Imx477 (B0272) motorized camera i2cset protocol

shineworld · July 5, 2022, 9:09am

Hi all.
There is a documentation about motorized imx477 (B0272) i2cset (bus 10 address 0xc) ?
I’m trying to improve autofocus and focuser code but I don’t know the focus camera operation parameters.

I was able to find something about PTZ camera but I guess are not applyable to my ixm219/447.

Thank you for support

Hi，
The motorized imx477 is different from PTZ camera. You are right. for the motorized camera, driver bus is i2c10 and address is 0x0c. You can refer to the demo we released for users:

    img_sobel = np.abs(cv2.Laplacian(img_gray, cv2.CV_16S, ksize=3))
    return cv2.mean(img_sobel)[0]
