1/3” Color Camera Module With Digital Output General Description The C3188A is a 1/3” color camera module with digital output. It uses OmniVision’s CMOS image sensor OV7620. Combining CMOS technology together with an eas y to use digital interface makes C3188A a low cost solution for higher quality video image application. The digital video port supplies a continuous 8/16 bit -wide image data stream. All camera functions, such as exposure, gamma, gain, white balance, color matrix, windowing, are programmable through I2C interface. In combine with OV511+, USB controller chip, it will be easily form a USB camera for PC application. Features: 326,688 pixels, VGA / CIF format Small size : 40 x 28 mm Lens: f=6mm (Optional) 8/16 bit video data : CCIR601, CCIR656, ZV port Read out - progressive / interlace Data format -YCrCb 4:2:2, GRB 4:2:2, RGB I2C interface Built in 10bit 2 ch A/D converter Electronic exposure / Gain / White balance control Image enhancement - brightness, contrast, gamma, saturation, sharpness, window, etc Internal / external synchronization scheme Frame exposure / line exposure option Wide dynamic range, anti blooming, zero smearing Single 5V operation Low power consumption (<120mW) Monochrome composite video signal output (60Hz) Application Example l Video Conferencing l PC Multimedia l Video Phone l Video Mail l Still Image l Machine Vision l Process control Note: Evaluation Board is available for C3188A Specification Imager OV7620, CMOS image sensor Array Size 664x492 pixels Pixel size 7.6 x 7.6 µm Scanning Progressive / interlace Effective image area 4.86mm x 3.64mm Electronic Exposure 500:1 Gamma Correction 128 curve settings S/N Ratio >48dB Min Illumination 2.5lux @F1.4 Operation Voltage 5 VDC Operation Current 120mW Active 10 µW Standby Lens (Optional) f6mm, F1.6 Pin Description 1~8 Y0~Y7 Digital output Y Bus.
