  What is the HP Digital Imaging Monitor? Apply to my operating system, Windows 7? I want to remove the icon from the task bar (toolbar in the lower right corner of the screen) that I never use it.

  Picardjc wrote that "Digital imaging monitor is part of the HP software that communicates with your HP printer. This program allows to read the inklevels, get an out of paper message, scan from the device to the computer and so on. It is not necessary, but it will restrict the use of printers if you delete. "Understood. But for my printer HP Officejet Pro 8000 A809a, what is the purpose of having the digital imaging monitor icon in the taskbar Windows7 sp1 of the Notification area (aka system tray)? My A809a is NOT an all-in-one that includes a scanner; It is simply a very good printer. When I start to print something, if you need ink or paper, that information is displayed on the screen of my computer. So I ask again: why is the icon of monitor digital imaging on the taskbar? I clicked on at the time of this icon (I not print anything, but as usual, the printer is turned on), and nothing happened. R.N. (Roger) Folsom _ P.S. below I'll post some other discussions (with links to their locations) of the digital imaging monitor, I discovered before finding this site on which I am writing. There are a variety of opinions on what makes the digital imaging monitor. HP Digital Imaging Monitor is for HP director system tray access. This is necessary if you want to use the buttons of all-in-one on a HP printer all in one to scan documents or transfer photos from a camera manually. Closing the icon monitor HP digital imaging in the Windows system tray can cause the HP all-in-one to lose part of its scanning features and not the connection error message. In this case, you can restore all functionality by restarting the computer or by starting the HP digital imaging monitor.

[Edited] 03/08/2011 14:05 - edited? 03/08/2011 14:08 Yes, it is safe to remove. In my view, it is usually in the program group under start / all programs / startup. Simply navigate under the Start button, right-click on it and delete! If it is not there, then remove it from the registry: run regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and delete it from the list in the right pane. If she is not there, then try hkey_current_user\\software\\microsoft\\windows\\currentversion\\run it's better than using msconfig and uncheck it. In my opinion, msconfig must always be set to Normal startup. Your printer will always print without that annoying obstructive utility called Digital Imaging Monitor. Ciao!

• Photo, what are the criteria for images selected from the collections of photos?

  With Photo on my Mac when I'm in the view "of the years', I see all my photos. When I switch to 'Moments' I see all the photos, especially older. When I go to "collections", then I self pictures? What are the criteria for images selected in 'collections' of photos? Thank you

  You should see all the photos in the Moments, the years, Collections, unless you have the "Summarize" option enabled in Photos > Preferences > General.  Then some pictures will be omitted, but the rules are not documented.

• What is the acquisition card OR 1426 compatible with a line/Linear array scanner?

  What is the acquisition card OR 1426 compatible with a line/Linear array scanner?

  I'm currently doing a feasibility study of the project that uses the NI 1426 and a linear Array Scanner acquisition card, and I would like to know if they are compatible with each other.

  Thanks in advance

  Martin

  Hi sandeepchinni,

  I agree with gunnesjr that we need more information about what you mean by Linear Array Scanner.  As he said if it is a scan line or an area then yes it will most likely compatible.  A small correction to what he says.  You need not buy NI Vision if all you need to do is to acquire images.  The framegrabber will be delivered with the software that is needed to work.  If you need to do any image processing then you need NI Vision.  The following knowledge base lists what is installed with the driver for the card.  Live that are installed with OR-IMAQ Vision Acquisition Software?

• Executives ignored in the acquisition of images with 4 Configuration of the camera (cards 2 x 1430), record only half of the expected data

  Hi all

  I have a VI that puts in place a continuous grab for four camera link cameras at 100 Hz (512 x 640).  I have the cameras running on an external clock of 100 Hz for synchronization (comes from box NI DAQ, trigger ports on 1430 cards are not connected to anything).  The VI sticks all the frames in a queue, and then I (slowly) he writes to disk after that I get what I want.

  The problem is, for a minute 4 capture, I get only about 14 000 items in the queue instead of 24 000.  Also, each image gets populated with a number of buffer, so I can see it is missing all the other images or something like that, sometimes it will jump 10 in a row, sometimes it will jump rare... any ideas?

  Here is a picture of my installation of collection (Scripture on the part of the disk is not displayed, but that pours out of the queue is fine)-

  

  Hello

  I see a number of problems with the approach in your VI that I'll try to cover...

  Your consumption with queues and images won't work as you wrote because the images are a type of reference data and so put them in the queues is not copy data values, only the references. So if you keep to the same reference to the image in a queue, they are all pointing to the same data of the image (which may be substituted).

  A better approach is to have two queues of images, representing the 'free' pads and then one that represents the images 'full' (your queue current consumer). You would then have your acquisition loop pull a 'free' image, fill it with data via a Get buffer call and then queue it for your use. Your consumer could pull this queue, do its thing and then queue the image to the queue 'free' for the producer to use again.

  In addition, your code does not currently use the lower level is VI buffer, so you take advantage of the buffering model input-output IMAQ uses internally. The simple Grab acquire VI returns only the most recent image, but if you fall at all it does not use the FIFO. You want to call make buffer with a buffer incremeenting number so that you do not skip the buffers and are allowed to get behind up to the number of buffers in the buffers configured list.

• Problem in the acquisition of images

  I use a ccd Hitachi, which worked fine until yesterday, all of a sudden, I have an "IMG_ERR_VLCK" error - cannot be locked on the video source (error 1074397153) who appears whenever I press on acquire.

  the cable seems very well made the pins, the domain controller is also correct, I don't know what happened
  I tried the solution written in common mistakes and still nothing.

  can someone help me please?

  Hi Dalia12,

  I see you've already found: http://digital.ni.com/public.nsf/allkb/3434173630CBC97686256F8000536593#1

  Who has a multiple troubleshooting techniques.

  As he has worked before, have you installed the new drivers or made any changes to the settings in the camera file or the device itself? If this isn't the case, it may be a hardware problem, in which case you have another camera, capture card, or cable to test?

• help the acquisition of images only when the light is on

  Hi, I need help to create an instrument.

  I need to create an instrument to:

  I have a black box with a camera. This camera will be connected to the pc via the USB port. When I press a pedal strong light comes througt it.

  I need that labview shows an image in real time when the light comes and stops showing the image when the light goes out, showing the last structure that was light. It's like a system called last taken image.

  for example:

  I have a pedal that start a strong brightness. LV doesn't show any picture, when I press the pedal and lights in LV stars to show the image when I stop pressing the button LV displays the last picture or image that was light. If he starts another moment to press the pedal LV begin to appear the new images until I stop to press the pedal.

  any idea?

  Thank you

• Keep all information collection during the acquisition of images when you use the basic IMAQ package

  I did show a command of X from IMAQ image control that has the ability to overlay dots and lines on an image, but when I put my control of X in my loop of acquiring image collections information disappears with each new picture that I acquire.

  How can I keep the overlay in place and just update the control with the new image and does not overwrite data overlay? I tried the function of superimposition of fusion, but this doesn't seem to work.

  Thank you.

  Overlays are completely erased when you acquire a new image.  You can create collections on a separate image, and then copy to each new image overlays until you view it.  The other option is to re-create overlays for each new image.

• What is the best audio format to import a CD?

  Dear people of the communities,

  What is the best format in terms of better sound quality for an import CD, regardless of the size of the file, just a pure sound quality?

  The goal is to save my music library CD and vinyl in a computer/drive and listening using a computer connected to a sound system 'Stereo' (not ' Surround', regular stereo) with speakers high quality stereo (L + R).

  So far, I've downloaded using a 320 kbps MP3 format. Listening to a CD quality is very poor.

  I use iTunes 10.7.x (as well as iTunes 12.x on a newer platform, but imports of CD I use version 10.7)

  All parameters are the following:

  Import using MP3 encoder =

  Parameters = custom

  Use the Error Correction = No.

  ---------------------------------------------

  Stereo BitRate = 320 Kbps

  VBR = No

  = 44,100 kHz sampling rate

  Channels = stereo

  Stereo mode = Normal

  Smart encoding = No

  Filter Freq below 10 Hz = No

  I think he wouldn't be WAV course, AIFF and Apple Lossless I know are both better quality, but using an Apple encoder can restrict what will be the player who is also important.

  Thank you

  Alon

  .

  Any lossless format will offer the best audio quality.  The available choices:

  • WAV is probably the most widely supported but it lacks the ability to incorporate metadata or illustrations, so while you can move the audio between different systems files as soon as you go outside iTunes you will lose all the artist / album / song information.
  • Apple Lossless (ALAC) is definitely the best choice in iTunes - he has the same metadata / support work such as MP3 or AAC and supports full 16/44.1 audio with file sizes about 65% of the equivalent WAV file
  • AIFF is very similar to the ALAC, except that (in the Variant used by iTunes), there is no lossless compression, so the file size will be larger

  The determining factor here will be where you intend to use the files - many other readers take in charge of the three options mentioned above, either natively or (for the ALAC and AIFF) using the appropriate plugins.  Unfortunately the lossless codec which has the broad support of all (FLAC) is not supported by iTunes.  There are, however, many utilities out there that can convert between ALAC and FLAC (and vice versa) if that proves necessary.

• What is the most important difference between 3D Picture control and controlling the display of Simulator

  I want to create a simulation of 3D on the front panel, and I see that we can use a 3D image control or a display of Simulator control. It seems that each of them can be used at the same position. What is the most important difference between 3D Picture control and display of Simulator?

  Hi sfh1,

  You are right, I found examples of Robotics that use 3D photo control and display Simulator control to display a scene 3D on the front panel. After further research, it seems that control the display of Simulator adds additional features compared to the 3D picture control. The control displays Simulator allows the user to right-click control during execution and change the background color, draw fashion, draw contact, view the ID of robot, display sensor data, suspension of service Simulator and reset service Simulator.

  More in depth on these options and the display of control Simulator can be found here:

• What is the important of the framework and what is its role?

  What is the important of the framework and what is its role?

  I guess you mean, NET Framework and its different versions.  It is a programming platform, some of your applications need this to work.  Instead of having to write completely every thing software developers scratch use so-called "frameworks" to ensure that their applications do certain things, for example, if you want to tell your program to save a file, just insert a little short of code that calls the framework to do real work, in this way, you don't have to write all the code to save the file and orders the programming for this platform.  Not only this saved a lot of work, he adds also in general more stability to the software that the programmer doesn't have to test and debug these programming functions that have been developed and tested by Microsoft, otherwise, it would be some sort similar to reinvent the wheel for each piece of software.  If you know a little more about programming, or on older versions of Windows 9 x, .NET Framework is like Visual Basic and the runtime libraries, it is a more recent incarnation of software platform.  It is best to not uninstall and play with these different versions, if you are part of your software may stop working.
