OV7725 phone camera module
● OV7725 phone camera module ntroduction
The OV7725 phone camera module uses the OV7725 CMOS type digital image sensor. It is divided into a cell phone camera module version with FIFO and a cell phone camera module version without FIFO.
● OV7725 mobile phone camera module feature
The size of the OV7725 mobile phone camera module is 33.4*30mm, it is small, and the working voltage is low.
Support the use of VGA, QVGA, and CIF to output image data of any size of 40*30.
The collected images support basic processing such as gamma curve, white balance, saturation, and chroma.
The version with FIFO is used with STM32F103VET6 Development Board and STM32F103 microcontroller development board STM32F103ZET6, and provides corresponding routines such as LCD real-time display, camera photo taking, and serial port real-time display of the host computer.
Note: Since the STM32 F1 series microcontroller is not fast enough to process information, it cannot process the 300,000-pixel data from the OV7725 mobile phone camera module in time. A FIFO must be added as a buffer. The FIFO chip can only store one frame of 320*240 pixel data.
