Block Diagram
Figure 2 shows the block diagram of ArduCAM mini shield which is composed by lens, image sensor and an ArduChip. The lens is changeable and can be mounted by S-mount (M12x0.5) or CS-mount lens holder. 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.
Functions
- 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.
- 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.
- JPEG Compression
The JPEG compression function is implemented in the image sensor. With proper register settings to the sensor, user can get different resolution with JPEG image stream output. It is recommended to use JPEG output to get higher resolution than RGB mode, due to the limitation of frame buffer.
- Normal Read and Burst Read Operation
Normal read operation reads each image data by sending a read command in one SPI read operation cycle. While burst read operation only need to send a read command then read multiple image data in one SPI read operation cycle. It is recommended to use burst read operation to get better throughput performance.
- Rewind Read Operation
Sometimes user wants to read the same frame of image data multiple times for processing, the rewind read operation is designed for this purpose. By resetting the read pointer to the beginning of the image data, user can read the same image data from the start point again.
- Low Power Mode
Some battery power device need save power when in the idle status, the ArduCAM offers the low power mode to reduce power consumption, by shutdown the sensor and memory circuits.
- Image Sensor Control
Image sensor control function is implemented in the image sensor. By setting proper set of register settings, user can control the exposure, white balance, brightness, contrast, color saturation and etc.
