Notice
IMX477 12.3MP Camera can only support the Raspberry Pi Compute Module series, it cannot be used with Raspberry Pi boards like Raspberry Pi Model 4B.
IMX477 12.3MP Camera can be used with Jetson Nano Developer Kit, if you want to use it with Jetson Nano, you need to install the driver. Please backup your OS before you install the driver because the driver is not suitable for IMX219.
FAQ
Answer:
In different shooting environments, the white balance effect may not be normal. Users can adjust the white balance parameters according to the actual usage.
The following OpenCV adjustment code is for reference only. (The code is shared by RPi Camera (G) users)
import picamera
import picamera.array
import cv2
from time import sleep
import numpy as np
def test_gcamera():
cv2.namedWindow("img",0)
with picamera.PiCamera() as camera:
camera.resolution = (1920, 1080)
camera.awb_mode = 'off'
rg, bg = (1.8, 1.4)
camera.awb_gains = (rg, bg)
with picamera.array.PiRGBArray(camera) as output:
for foo in camera.capture_continuous(output, 'rgb', use_video_port=True):
img = cv2.cvtColor(output.array, cv2.COLOR_RGB2BGR)
cv2.imshow("img", img)
cv2.waitKey(1)
cv2.imwrite("test.jpg",img)
r, g, b = (np.mean(output.array[..., i]) for i in range(3))
if abs(r - g) > 2:
if r > g:
rg -= 0.1
else:
rg += 0.1
if abs(b - g) > 1:
if b > g:
bg -= 0.1
else:
bg += 0.1
camera.awb_gains = (rg, bg)
output.seek(0)
output.truncate(0)
