Camera Quality

[ckrusecodes]

Is there any way to adjust the settings of the camera via your library? For example, increase brightness? I find that a large white and black qr code will scan. but anything small, or using a non standard color does not scan. I have some large codes that are a black/gray scale that won't scan. They scan fine with a iPhone, but that is obviously a much better camera.

you can do something like this in setup ==>

sensor_t *sensor = esp_camera_sensor_get();
sensor->set_framesize(sensor, FRAMESIZE_CIF);
sensor->set_pixformat(sensor, PIXFORMAT_GRAYSCALE);

You can also get hook to camera_config_t like ==>

ESP32QRCodeReader reader(CAMERA_MODEL_AI_THINKER,FRAMESIZE_CIF);
reader.cameraConfig.pixel_format = PIXFORMAT_GRAYSCALE;

hope this helps.
