1，General Description
The BF2507 is a highly integrated, high performance, 1/4-inch 5 Megapixel CMOS Image Sensor (CIS) with digital video parallel and MIPI CSI-2(Mobile Industry Processor Interface Camera Serial Interface 2) compliant interfaces. It is fabricated with the world's most advanced CMOS image sensor process to realize ultra-low dark noise, high sensitivity and very low power imaging system
The CMOS sensor consists of 2608 × 1952 active pixel array in 1/4 inch optical format. It has integrated noise canceling CDS (Correlated Double Sampling) circuits, Programmable analogue global gain and separated R/G/B gain controller, auto black level compensation and on-chip 10-bit ADC
The BF2507 is capable of operating at up to 15 frames per second at 96MHz master clock in OSXGA mode, with complete user control over image quality and data formatting. BF2507 incorporates sophisticated on-chip image processing functions, including Mirror and Flip, windowing and subsample, Test Patterns, Auto Flickers Cancellation, Auto Black Level Calibration (BLC), Lens Shading Correction (LSC), Auto Exposure, Auto White Balance (AWB), Gamma Correction, Auto Focus, Defect Pixel Correction (DPC), De noising, Black Sun Cancellation, Image Downscaling, and so on.
