37、2.7-inch full size HD CMOS image sensor that provides the full functionality of a single 1080p (1920x1080) camera using OmniPixel3-HS? technology in a small footprint package. It provides full-frame, sub-sampled and windowed 10-bit images in various formats via the control of the Serial Camera Contr

38、ol Bus (SCCB) interface or MIPI interface.The OV2710 has an image array capable of operating at up to 30 frames per second (fps) in 1080P resolution with complete user control over image quality, formatting and output data transfer. All required image processing functions, including exposure control

39、 white balance, defective pixel canceling, lens shading correction etc., are programmable through the SCCB interface. In addition, OmniVision image sensors use proprietary sensor technology to improve image quality by reducing or eliminating common lighting/electrical sources of image contamination

40、 such as fixed pattern noise, smearing, etc., to produce a clean, fully stable, color image.For customized information purposes, the OV2710 includes a one-time programmable (OTP) memory.The OV2710 has a one lane MIPI interface and a traditional parallel digital video port (DVP).9.2 architectureThe

41、OV2710 sensor core generates stream pixel data at a constant frame rate, indicated by HREF, VSYNC, and PCLK. figure 2-1 shows the functional block diagram of the OV2710 image sensor.The timing generator outputs signals to access the rows of the image array, precharging and sampling the rows of array

42、 in series. In the time between pre-charging and sampling a row, the charge in the pixels decreases with the time exposed to the incident light. This is known as exposure time.The exposure time is controlled by adjusting the time interval between precharging and sampling. After the data of the pixels in the row has been sampled, it is processed through analog circuitry to correct the offset and multiply the data with corresponding gain. Following analog processing is the ADC which outputs 10-bit data for each pixel in the array.
