Besides the obvious change from HQVGA to QQVGA, any other suggestions to the code below that works well for the standard camera?
Reset sensor
sensor.reset()
sensor.set_contrast(3)
sensor.set_gainceiling(16)
HQVGA and GRAYSCALE are the best for face tracking.
sensor.set_framesize(sensor.HQVGA)
sensor.set_pixformat(sensor.GRAYSCALE)
sensor.set_framebuffers(1)
