Hi Kevin,
We are using the uCAM-III during night time using an infrared lighting source (940nm) using batteries. In order to reduce power usage is it possible to switch the IR lighting source on, take a snap shot (one data frame) using the getpic command and then turn off the IR lighting source? During the off time the frame is transferred to the host (Atmel SAMD21) over a dedicated serial line.
The uCAM-III coms setup is 921600, and 8 bit gray scale, RAW mode 60x80 or 128x96.
Images are captured every 0.5 second at 60x80
From previous data sheet the total time (Ttotal) the image is captured and sent is Ttotal =Tframe + Tshutter.
where Tframe is the time to transfer one data frame of image (header and payload) from uCAM-III to the host
and Tshutter is the time after getpic starts to be sent before image processing begins (Datasheet specs a range between 150 and 200ms)
How does the uCAM-III process the image exposure/brightness/contrast to capture the frame into memory? Is it only during Tshutter time when getpic received from host or during Tshutter and Tframe, or processes it in the background ie any time the uCAM-III is ON?
The images are in low light so may need some time for processing.
Regards
Gerald
