GigE Camera: focus and zoom control?

• Google Maps: pan and zoom controls are not displayed. 'PIN' markers can appear only once, and then disappear.

  Loading Google Maps, either directly, or where they are incorporated into other sites, orders pan and zoom are not displayed. Location markers 'PIN' can appear only once, but disappear after doing anything with the card. I'm on the last Windows XP and latest Firefox. This problem is long-standing and has remained the same during several different versions of Firefox and Windows updates. I tried "CTRL-0' no effect."

  Problem solved by 'Reset Firefox'. Before that, tried "Safe Mode", no difference. Not aware of the limits on the cookies or the memory usage. Controls on the left (Pan, zoom) for Google Maps were good here and in usual and sizing correct positions and could be found with the cursor and activate it, but 'ghosts' that were not display. Same problem if the content was maps or satellite pix. Reset solved the problem.

• Adobe Camera Raw and exposure control

  I have a huge problem in the cab for a few weeks. Most of the time I can not use the command of exposure because the parameter jumps to "0.00" whenever I have release the mouse button or click elsewhere on the screen. It goes the same for the adjustment brush.

  It is pretty hard to explain, so I recorded a short film.

  Sometimes it works all of a sudden, but 95% of the time that it does not work.

  Any suggestions how to solve this problem? Y at - it a setting I accidentally hit?

• 3D photo orthographic view zoom control - camera put in place?

  I try to display two controls 3D image.  A poster of the 3D objects (Auto Projection: Perspective, Camera Controller: spherical).  This 3D image works fine and I have no problem with him.  Other Contol photo is intended to simulate a 2D to 3D, essentially a Plan view object image.  To do this, I made an image with an orthogonal view 3D control.  I put the camera to see through top (z axis) and set a goal to be the positive y-axis.

  I've attached an example vi (labview 2013 SP1) that creates simple 3D objects and displays them using the same camera Position in Perspective and orthographic.  Initial start-up, the orthographic image is zoomed in strongly. If I Zoom in manually (button press and hold Shift and mouse upwards or downwards), then the orthographic image will set itself in the right position of the camera.  This is essentially the solution to my problem, but I can't assume that the user will have the ability to zoom in manually the image.  So I need to set it programmatically.

  If you manual adjust the display on a screen (rotation and zoom), then click on the button Set camera, two images will give a plan view, but only the Image point of view will be the right zoom camera or the distance.  The spelling remains to the last zoom distance.

  Is it possible to set the distance of the camera for orthographic projection by programming?   I have tried running with the perspective 3D picture control, set the distance of the camera and then change to spelling, but this still translates into a spell zoomed image.  Reading, I did it, I think I'm trying the impossible.  Does anyone have another suggestion to get the same result.  I've used 2D image functions to generate the image, but found that this inefficient method.

  And suggestions would be great.

  Thank you

  Hi Relec,

  Thanks (and congratulations) for this inspiring demo!

  Took me all to work out, but I might have found something that might help us with the orthographic projection.

  Sometimes, back someone posted a way to collect the current data of the camera. Sorry I lost the source. But here's my version as a Get3DCameraPosition.vi using the ModelViewMatrix.

  Unfortunately this does not return the current target and so a bit of guessing in the right Direction is necessary.

  I am impressed that you found a way to make the shift Zoom-possible movement on the spelling window.

  It seems that a whole thread to http://forums.ni.com/t5/LabVIEW/3D-Picture-Control-Doesn-t-Zoom-in-Orthographic-Mode/td-p/1544460/p... was not able to know which.

  In the meantime, I found a way using the ProjectionMatrix to create a magnifying glass effect which build in your demo using the mouse wheel.

  Overall, I tried to translate the camera movements from the window from the perspective of the ortho - assuming it is what you were after?

  Yet once the missing information from the target do not quite right.

• Adjust the size of the frame of the focus when you use Pan and zoom tool in first 14?

  I'm learning to use the pan & zoom tool through Adobe's Classroom in a Book for first elements 11.  The book is excellent, but as his writings for a generation of software of creation that is 3 years old, I'm trying to tackle a smaller image section that lets you control the default structure more small bowl size. (using the angle of the image update)

  Is it possible to adjust the image to a size smaller than the smallest default size allowed?  Thanks for your help!

  provlima

  I am not 14 as being different from 11 regarding the resizing of the workspace Pan and Zoom focus frame (by clicking on - or +). And I have not found a way to adapt a framework of development less than its smaller default size allowed using the-. or otherwise.

• Camera Raw loses system focus and becomes idle

  While working in ACR if I hover over one of the command buttons, Save the Image, Open the Image, Cancelor done a few seconds the 'bubble' for the poster button and as soon as I move the mouse again the entire Camera Raw windows loses system focus and becomes inactive (each tab, menu, controls, etc., becomes gray).  To return to the development of the system, move the mouse to the taskbar of windows 7, then returned in Camera Raw.  If the fullscreen in Camera Raw box is active the only way to regain the focus system is to press the Windows key twice on the keyboard and move the mouse over the taskbar tray.  This is getting quite frustrating.  Clues?

  It is not normally do, I assure you.  Normally the ToolTips just pop up and Camera Raw remains active.

• How must better panning and zoom like a real camera

  I took a bunch of 4K videos I want to pan and zoom.  When I use the key to pan and zoom image it always comes out a sort of jerky and evil.  Anyway to make it smooth as actually moving a camera?

  are there other tools that help with that?

  Here is what I get, not so good...

  Tammy during his lesson of surfing in Santa Cruz - YouTube

  One way to smooth out the pan and zoom is to have keyframes begins and ends before and after the element appears on the timeline.  This way, the clip is already in motion when it appears and it's always moving when is disappears.

  If there is a transition, be sure that the keyframes are before and after the handles.  If a few cuts, as some images before and after are OK.

• Connection to CVS GigE camera via a network switch

  It is a fundamental and very simple question!

  I intend to connect two GigE cameras to NI CVS-1458RT for an application of Imaging. When I tested the configuration in MAX, I realized that I can connect the cameras directly to the PoE ports, or alternatively, connect the cameras directly to the network switch and in both cases, connect the CVS to my network via its ethernet port. I was wondering if there is a benefit by connecting directly the VCA cameras, if I do not anticipate supply their Poe or if my switch has PoE Betacam.

  Thank you

  Usually, you always want your cameras on dedicated lines, or at least only sharing bandwidth with other devices. The mechanism of transport used by GigE Vision isn't really sharing good bandwidth with other devices. If you only share the bandwidth on a link given with other devices, you can throttle each take only a percentage of the total bandwidth. If you have devices without camera on the link, they don't usually have a mechanism to control the gap inter-frame limitation insofar as GigE vision made which would be necessary for properly sharing the bandwidth without remove the packages of bandwidth.

  If you end up sharing one of the ports for the operation and configuration of the CVS on the network, you will be at the risk of losing image data packets whenever the rest of the traffic is sent. Although there are mechanisms in place to return data, these add latency and jitter to your purchase.

• How to identify a GigE camera by IP address

  I have a system with 8 Basler Ace GigE cameras, all on static IP addresses on the same subnet.  I would like to be able to exchange any device with a new one that is configured to the same IP and my LabView RT running on an Exchange virtual server program automatically starts using the new camera.  The LabVIEW program already sets the settings in the camera, if I don't want the user to have to use MAX for any configuration of the camera.  I want to just the user to use the Basler IP configuration tool and the tool of Basler to focus the camera, then having my program discover the camera by its IP address.

  However, I have not found an IMAQdx tool that allows me to distinguish the cameras by its IP address.  The discovering Ethernet cameras VI has an address entry, but it is only a mask and cannot me narrowly find just a single camera on an IP address.  I have not found any camera property or an attribute that returns the IP address.

  So, if I have a bunch of cameras and want to identify who is who, by his IP address, how can I do?

  Hi Ken,

  The main identifier imaqdx uses to track/locate cameras is serial number, which is identical to its MAC address for GigE Vision cameras in IMAQdx. Unfortunately us don't really use IP address as any kind of ID to connect with a specific camera, because we assume that the IP address can be dynamic and flexible (makes it spec GigE Vision DHCP and link-local addressing a requirement standard and everything is designed to allow these cases to work well).

  That said, there is an attribute called 'CameraInformation::IPAddress' that you can query to see the IP address of the camera. The only downside is we do not currently provide this information via the Enumerate mechanism - you first need to query this property of the device. Your application might first browse the cameras and do a mapping of serial to IP addresses?

  Hope this helps,

  Eric

• VB6 with GigE cameras?

  I use Vision Devlopment Module 8.5 with VB6.   I wrote a lot of code using activeX controls for cameras, firewire 1394.   Are there for GigE cameras VB6 activeX controls?  If so, can you put link here for examples.  Thank you

  Hi Dan,.

  IMAQdx documentation indicates that it has supported inherited from MSVB6. Your device should work with these examples as long as it meets the standards GigE or correct DCAM to work with IMAQdx, because it's always using our IMAQdx drivers.

  I'm not sure the support ActiveX specifically for GigE cameras, but once that you have connected to your camera with IMAQdx in VB6, I don't see why you shouldn't be able to use the functions you used before. I suggest that you try to change your existing code to connect you with your GigE camera and test the functionality of your ActiveX code.

  Thank you

• Windows updates driver Nvidia and Nvidia Control panel stops working

  I was choosing to update the video card myself with the latest driver 310.09 being installed, and everything was fine. Then I started having "failed to initialize Nvidia Control Panel, you don't have permission to access or access denied errors at startup and to the continuation of the investigation I found updated encrypted files (c:\windows\system32\nvcpl.dll being one of many) and a Nvidia driver recent 311 already in the section updates installed windows from the control panel."

  Now, I have no Nvidia Control Panel, but I managed to roll back the driver to 310.09, but still with no possibility to install driver 314, or remove any previous version using uninstallers. I'm stuck in the middle with nowhere to go!  I want my back Nvidia Control Panel, and I hate error messages!

  Problem not solved! When I did the screen went black, with me ends up having to re-start, the machine came back, and before I can do anything Windows back to or downloaded 311 driver and I'm at square one. Impossible to uninstall any Nvidia or reinstall anything Nvidia.

  If Windows will update a 3rd party driver why it deletes the old software first. Now I have the supplied Windows driver 311 mixed with the old Nvidia provided 310 software update! It's no wonder that nothing works!

• Purpose of track and zoom green screen?

  I have two shots, I'm trying to merge.  One is a handheld zoom and travelling of a person wearing a mask, and I'm putting an ORB that I green projected onto the front of the mask.  I had tried to animate the sequence manually, but decided to try after effects CC because it seemed that it would be a simple solution (as an anchor to a 3D point).  I was not able to find a solution that works well, but the closest I came is to create a tracker of the camera but do not compensate for the zoom when I move the layer of the orb to the solid that I create.  I hope it's just something simple I am missing! Thanks for your help - Andrew

  The simplest solution is that if you see the shots. Here are some things to consider. Point of view is controlled by the position of the camera, focal control framing. You try to mix a mobile camera with an evolution of the focal length. This means that there is a problem immediately top with perspective. Maybe it's not important because I'm not sure of what look like your shots. So it is this hand held shot of a person wearing a mask and that they walk so the camera and the person are moving. Then there's this orb that was shot on a green screen that you want to attach to the mask. You are zoomed out of the person while the perspective shifts across shot because the camera is moving and the perspective of the person moving in the changes of shooting because they move around the scene and the scale or the framing of the picture changes because you are zooming. Then you have an ORB (something spherical) you shot with a camera locked for perspective and framing does not change. When you say you want to put the ORB on the forehead of the mask I'm picturing the composite final as a shot of an actor wearing a mask that has some sort of jewelry that looks like an ORB and the actor is walking toward the camera while the camera zooms in. If it is we break down what is happening in the shot and the challenges that await you.

  Let's take the ORB first. It is a locked low blow so there is no problem to change perspective or the change of scale (zoom with camera) deals. The only thing you can do is hope that the prospect of the ORB is close enough to the prospect of the actors face which does not matter.

  Now let's talk about the outstretched hand of shooting of the actor. When the camera moves there is a shift in perspective in the whole scene. Because the actor also moves, there is a change in the perspective of the actor. Since the ORB will be attached to the mask's actor it is really unnecessary to worry about the perspective change in the background, you only need to worry with the change of point of view of the actor. If the distance between the camera and the actor remains fairly constant, then the change of perspective probably won't be much of a factor. If the actor begins 10 feet from the camera and ends with 2 feet of it camera then you have to deal with the change of point of view as well. Now consider the zoom.

  Zoom does not change the point of view, it changes only the framing or the extent of the shooting. You have to find a way to measure this change globally and apply the change to the scale of the layer of the orb. Fortunately, this part is not too hard.

  Now we are going to attach the ORB to the mask. If the distance between the camera and the actor is relatively constant so you don't have to worry much about a change of perspective. This means that the best thing to do would be to stabilize the mask so that it is not moving. If the player does not turn their head a lot so it's pretty easy. If the actor turns his head then it becomes much more difficult. Suppose that the actor don't move their head. You'll need to follow the position of the mask and the face of the actors and scale and rotation. Then, you need to apply this position, scale, and rotation to the layer of the orb. You could do that little monitoring by tracking the eye holes in the mask or by the monitoring of the upper part of the head and the Chin or the other two parts of the mask with a geometry set. Once the head and, therefore, the mask is followed for the position, scale and rotation, you can apply these data to the orb. There are basically two ways to do it. You can either stabilize shooting so that the mask does not move in the image, then place the ORB on the stabilized mask and then put the movement in shooting and apply tracking to the layer with the orb data so that it moves with the head of the actors. The other option is simply to apply directly tracking data to the layer of the orb in position on the mask and match the scale and rotation of the changes at the head of the actors. You can use AE tracker or tracker in Mocha for either. It is easier and more efficient method depends entirely on shooting.

  If the actor turns his head during the shooting, then everything in the previous paragraph applies more you need follow the change of perspective in the minds of the players. Maybe it's where you use the tracking camera AE and Mocha AE not having any real 3D tracking tools that track different elements 3D as the face of actors in a scene. According to the shooting, there may be a way to use tracker AE camera to simply follow the movement of the face and then add a sphere 3D layer so that it will follow with the movement of the actor. You can even use a 3D object. You would do that by stabilizing the first actors to head in the shot so that the position, scale and head actors has been locked. You would then duplicate this layer and mask the layer so that only the head of the actors was visible in the shot. You would then dial before shooting hidden just head of actors and run the tracker of the camera on the demo. By doing this, you may be able to fool the camera into thinking that the actors head does not move, but the camera moves around the head of the actors. If you can get a good track then you can add a null value and a camera to the scene and then the 3D layer orb and i match position ' t to null. If the ORB remains attached to the mask actors as it should then you could turn off the layer of film, leaving only the orb and the camera in the demo.

  Now, all you have to do is to put the rear movement essentially shot by reversing the stabilization and applied these data to follow-up to the pre comped ORB.

  Here is a tutorial of Mikey who is good enough and gives you an idea of how do track camera mobile head.

  I don't know if that helps at all, but it should point you in the right direction. The explanation also stresses that the planning of the production before when you do something like this. Just Runnin ' and gunnine you can get in a lot of trouble.

• Pan and Zoom effect, what version of PE it introduced?

  I love my PE 3.0 but it does not seem to offer the Pan and Zoom effect. Or am I just not see it.  Does anyone know what later introduced? I know 8.0 has it, but when it come?  The embedded Photoshop 5.0 version, it came with a a pan slide show, just found out.

  Also, I am familiar with keyframes, that would be helpful with pan 3.0? or I need a newer version.  Any good tutorials for this?

  Thank you

  Pan & Zoom is available in all versions that offer keyframes on the fixed effects > Motion > scale (Zoom) and the movement > Position (Pan). Which may have been introduced would be Presets to make those who have 'a button '. Don't know when those who saw the light of day. I do not use them in the pre 4 and would not forward 8 or 9, as I want to control, and also the ability to determine what MY subject is in a picture. No amount of AI can do for me, so a "Preset" is central to about a zero chance to do exactly what I want.

  At some point, PSE said the automatic random Pan & Zoom. Were once again, I have made a slide show in it, I would not apply, as I would Motion Keyframe > Position and movement > pre scale.

  In the pre 3, I firmly believe that you have the effects Panel (access via effects change for a Clip/still), and the ability to keyframe the two movement > scale and Motion > Position. This allows to adjust the settings for these effects over time, i.e. to create a Zoom and create a pan. Other than the fact that make you these by hand, by eye and by mind, but with the ultimate control, you have the features - all simply not automatically applied via a single button.

  Good luck

• What are the ranks for each zoom control

  I want to make sure that websites are accessible to 200%, as required by the WCAG. How much time do I need to repeat the 'increase zoom' to reach 200%? It would also be useful to know what extra step each Ctrl + [+] to get.

  Thanks for any help you can give.

  Oh, I should mention that you can move the zoom controls in the Panel of the menu on the toolbar for easier reading at-a-glance.

  Near the top of the Panel "3-bar" menu, you will see something like:

  - | 100% | +
  

  To move at the end of the toolbar, right-click and choose move from the toolbar.

  To move it to another location in the toolbar, use the customization feature. See: Customize Firefox commands, buttons, and toolbars.

  However, when you read the percentage on that zoom level reset button in the Center, keep in mind that that is compared to your zoom level base and the history itself.
