From what you describe I assume that you are using a color camera with a Bayer pattern. The sensor of such a camera has a Bayer mosaic filter applied to its pixels with which it is capable of acquiring color images with sub sampled color data. These sub sampled color images are more economic in terms of bandwidth (see also this discussion) and are technically transmitted in a format with only 8 bits per pixel. In the computer, this raw Bayer format is usually visualized as monochrome, but if you have a closer look at these images you can still see the actual Bayer filter.
For example the Bayer representation of this image:
looks like this (200% zoom):
What might be happening on your system:
- The GenICamBrowser detects the Bayer format and applies the necessary conversion in order to be able to display the images as color images.
- However, this does not alter the actual image data. When trying to save the image, only the actual image data, not the current visualization will be stored to disc, and as the actual image data seems to still be mono8, only a monochrome image will be stored (in which you will most likely be able to see the characteristic pattern…).
- The GenICam.vin also only acquires the raw image data - which as you confirmed is a monochrome image.
Can you double check your $CVBDATA/GenICam.ini file on both systems? There might be differences between the two systems, especially the
PixelFormat settings seems to be different according to your account (a setting
PixelFormat = 0 on the Jetson would explain the behavior you are seeing, whereas the PC seems to be using either
PixelFormat = 5 or
PixelFormat = 2 see also here for a description of these settings).
