The invention discloses an ARM (random access memory) camera interface based video collection displaying system which comprises a black-and-white CCD (charge coupled device) camera, a video amplifier or an A/D (analog-digital) convertor, an FPGA (field programmable gate array), an ARM with the camera interface and a video sync separator. An SDRAM (synchronous dynamic random access memory), an FLASH and an LCD (liquid crystal display) touch screen which are connected with the RAM are arranged on the periphery of the ARM, the FPGA receives data video signals outputted by the A/D convertor and converts the digital video signals into a YCbCr4:2:2 format prior to inputting the digital video signals into the digital camera interface of the ARM, and a video is displayed through the LCD touch screen; the video sync separator separates the signals outputted by the black-and-white CCD camera into a horizontal sync signal and a field sync signal which are transmitted to the FPGA, the FPGA generates a camera control sequ
