H7 cam has a green filter?

Hi! Newbie here, I got my hands on the OpenMV cam H7 and it was working great, tried out some examples which were really helpful. Then I updated the firmware to the latest version 4.1.2, and now the camera looks like it has a green filter when the pixel format is set to RGB565. Anything suggestions to remedy this? Thanks.

Hmmm, wait there might be a software regression. I just tested the firmware on an H7 pure thermal with the same camera and this does not happen.

Can you post a picture of your board?

Hi, I have an H7 Plus camera and I don’t get a green image.

# Untitled - By: kwagyeman - Sun Dec 5 2021

import sensor, image, time

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time = 2000)

clock = time.clock()

while(True):
    clock.tick()
    img = sensor.snapshot()
    print(clock.fps())

Please run this:

import omv

print(omv.arch())

Should print: OMV4P H7 32768 SDRAM

If it prints something else it means you have the wrong firmware onboard.

Okay so I definitely installed the wrong firmware somehow. I was able to get the right one and my problem is fixed, thank you for your help!
