Why the default OV2640 camera on the development board may not be suitable for this example? (AIV-633) #268

It's not really an issue per se, but I used this example on the new ESP-S3-EYE v2.2 with mixed results.

In the read-me file it is stated that:

"Note: the default OV2640 camera on the development board may not be suitable for this example."

Why? or what would be the best camera for QR decoding?

Thanks, Sergio

Hi, Because the default focal length of the camera is for facial recognition tasks, relatively long, and QR code recognition often occurs at a closer distance, a camera with a shorter focal length would be more suitable.
