6 Block Diagram

Figure 2 shows the block diagram of ArduCAM mini shield which is composed by lens,

image sensor and an ArduChip. The image sensor is 5MP CMOS OV5642 from Omnivision. The

ArduChip uses ArduCAM proprietary third generation camera controller technology which

handles the complex camera, memory and user interface hardware timing and provides a user

friendly SPI interface.

7 Functions

7.1 Single Capture Mode

Single capture mode is the default capture mode of the camera. After issuing a capture

command via SPI port, the ArduCAM will wait for a new frame and buffer the one entire image

data to the frame buffer, and then assert the completion flag bit in the register. User only needs to

poll the flag bit from the register to check out if the capture is done.

7.2 Multiple Capture Mode

Multiple capture mode is advanced capture mode. By setting the number of frames in the

capture register, the ArduCAM will capture consequent frames after issuing capture command.

Note that number of frames should be set properly and make sure do not exceed the maximum

memory space. Multi capture mode can be use to take the same scene with different exposure to

create HDR images.

7.3 Short Movie Capture Mode

Short movie capture mode is the continuous capture mode until the 8MByte frame is full.

User can use this mode record couple of seconds video and save to AVI file into SD card.
