Query regarding zoom_image

[anuprao]

Hi ! This is not an issue but a query.

Thank you for publishing your code. It is very helpful.

I am trying to obtain a 320x240 crop from a (2592x1944) on OV5640 setup.

I used the zoom_image function in your code to generate values for cropping. But I get only black image returned as data from sensor.

All the register values generated by the function are set in the same order.

Is there anything else I should look at ?

Regards,
Anup

Hi Anup,

Have a look at sourcefile gc0308.c to learn using the zoom_image function.
This will crop to any size with varying fps.
There is a standard 320X240 resolution init sequence in ov5640.c that you can select with your
viewer like vlc or cheese..
black picture could be timing problems.
