HQ Camera Raw Sensor Format with Picamera2 not working for 1332x990

[waikeat2397]

am playing with HQ Camera sensor formats. By referring to below snippets, we can know that HQ camera support 4 raw sensor mode.

I am trying to set raw sensor format to the lowest resolution. But end out it auto select second highest sensor format.

config = picam2.create_still_configuration(main={"size": (1332, 990), "format": "BGR888"}, raw={"size": (1332, 990)}) picam2.configure(config)

Anybody ran into the same problem as me? I tried with raspberry pi camera module v3, and its working.

FYI, I am using Raspberry Pi Model 4, HQ Camera, 2024-11-19-raspios-bookworm, libcamera v0.5.0, picamera2 0.3.27

The safest thing is to specify exactly the size and bit depth of the camera mode that you want. So maybe like this:

main = {"size": (1332, 990), "format": "BGR888"}
sensor = {'output_size': (1332, 990), 'bit_depth': 10}
config = picam2.create_still_configuration(main, sensor=sensor)

(If you don't specify everything, it may default to preferring a higher bit depth.)
