16-Bit Display Mapping Is Not Working On IMAQ Image Display Primary Software Version: 2.0 Primary Software Fixed Version: Secondary Software:
Problem: Whenever I right click an IMAQ Image Display in LabVIEW and select 16-Bit Display Mapping..., none of the options in this menu seem to change the appearance of the image. How can I solve this? Solution: This is actually expected behavior. NI-IMAQ and NI-IMAQ for 1394 specify the bit depth for the images they acquire, and when the bit depth for an image is known, the IMAQ Image Display uses this bit depth. When loading a file from disk, the file format may not specify the bit depth, in which case the display falls back to the settings specified by right clicking and selecting 16-Bit Display Mapping.... If you want to use the user settings for an image with a known bit depth, use the IMAQ Image Bit Depth.vi to set the bit depth for the image back to zero, which represents unknown. The mapping settings will then map your pixel values accordingly. Related Links: Attachments:
