CMOS Camera Module MT9D111 is a 1/3.2 inch 2-megapixel CMOS image sensor with an integrated advanced camera system. The camera system features a microcontroller (MCU) and a sophisticated image flow processor (IFP) with a real-time JPEG encoder. It also includes a programmable general purpose I/O module (GPIO), which can be used to control external auto focus, optical zoom, or mechanical shutter.
The microcontroller manages all components of the camera system and sets key operation parameters for the sensor core to optimize the quality of raw image data entering the IFP.
The sensor core consists of an active pixel array of 1668 x 1248 pixels, programmable timing and control circuitry including a PLL and external flash support, analog signal chain with automatic offset correction and programmable gain, and two 10-bit A/D converters (ADC). The entire system-on-a-chip (SOC) has ultra-low power requirements and superior low-light performance that is particularly suitable for mobile applications.
