Description
Camera module for Arduino 5 MPx with a resolution of 2592 px x 1944 and speeds up to 120 frames per second. It extends the capabilities of the system, for example, microcontrollers Arduino, STM32 and mini-computers Raspberry Pi, with the possibility of taking photos and recording video clips. The device operates with a voltage of 3.3 V and 5 V, it communicates via SPI, the angle of view - 24 ° (non-linear), the lens is 1/4".
Modes of operation
- Single Capture Mode - the default mode of the device after the indicating the command via SPI, the camera captures a frame and adds it to the buffer, while setting a flag in the registry. By checking the state of the flag, the user knows that the read has been completed.
- Multiple Capture Mode - an advanced mode where the user specifies the number of frames to be captured. Please note that the number of frames cannot exceed the capacity of the buffer.
- JPEG Compression - in this mode, the output are compressed data in the JPG format with higher resolution, than RGB.
- Normal Read and Burst Read Operation - in this mode, it is sufficient to send a read command for receiving the continuous transmission of frames via an SPI interface.
- Rewind the Read Operation - it allows to read, several times, the same data contained in the buffer.
- Low Power Mode - disables the sensor and transducer in order to save energy.
- Image Sensor Control - mode change parameters of the camera sensor, i.a. balance, brightness, contrast and saturation.
