I am trying to process a raw image using the NvMedia ISP API (nvmedia_isp.h) in order to get the histogram. Unfortunately the image comes out purple (the green channel is missing) and the histogram registers all pixels in the top bins. I believe the ISP is not configured correctly. We have a camera_overrides.isp, but I’m not sure how these settings would need to be loaded. I am currently manually setting some of the key settings, like the colour calibration matrix, using the ISP API.
I see there is a function called NvMediaISPSettingsLoadConfig, but it expects a binary blob file. How can I create or obtain such a blob file? I have a .nito file for this sensor, but apparently this isn’t the binary format that is expected here, because the call fails if I try to load that.
Anyone have any tips either to the source of the problems or how to load the ISP configuration?
(As a sidenote: the component I’m integrating this into is currently using SIPL, the surfaces I use as source and destination are the ones returned by SIPL. If the image is processed using SIPL, it looks fine, but I don’t see the option to get the histogram there under 5.1.6.)
