the mains frequency is dependant on the status of the GPIO3 pin, which can be achieved by population of a PCB link at a late
stage in production, once the country of destination is known, without the need to change the crystal frequency.
The auto exposure and gain algorithm is always enabled during ’Snapshot’/self-timer/continuous mode. When the shutter button
is pressed in ‘Snapshot’ mode, the chipset captures an image if the exposure and gain value has reached a suitable value for the
current scene. If the light detected has suddenly changed, the camera may emit an audible tone to indicate that more time is
required to reach the correct exposure target. In ‘Snapshot’ mode the chipset only captures the image data if sufficient light is
present in the image. In continuous capture mode, the chipset captures images regardless of whether enough light is present.
Note: Auto-detect of the mains lighting frequency is not currently supported.
