Overview

The OV4688 is a high-performance 4-megapixel CameraChip sensor in a native 16:9 high definition (HD) format designed to deliver ultra-high quality fast frame rate HD video for mobile devices. Built on a new 2-micron OmniBSI-2™ pixel, the OV4688 offers best-in-class low-light performance with a 40 percent increase in sensitivity compared to the 1.75-micron OmniBSI-2 pixel.

The OV4688 supports timing for two High Dynamic Range (HDR) modes, frame-based sequential HDR and line-based staggered HDR. A major advantage of staggered mode over sequential mode is a significant reduction of motion artifacts in the captured images. The sensor's enhanced performance, along with its ability to record full resolution 4MP @ 90 frames per second (fps), allows it to capture best-in-class video and high-speed photography with zero shutter lag, and video HDR at 30 fps.

The 1/3-inch OV4688 can also capture 1080p HD at 120 fps with electronic image stabilization (EIS), or 720p HD at 180 fps. The OV4688's high frame rates enable additional key benefits, including full-resolution continuous frame capture or burst photography and recording of high-quality slow-motion video.

The OV4688 features a high-speed 4-lane MIPI serial output interface to facilitate the required high data transfer rate and fits into an 8.5 x 8.5 mm module with az-height of about 5 mm.
