Picture sensor elevates smartphone HDR


Omnivision’s OV50K40 smartphone picture sensor with TheiaCel know-how achieves human eye-level excessive dynamic vary (HDR) with a single publicity. Initially launched in automotive picture sensors, TheiCel employs lateral overflow integration capacitors (LOFIC) to offer superior single-exposure HDR, no matter lighting situations.

The OV50K40 50-Mpixel picture sensor encompasses a 1.2-µm pixel in a 1/1.3-in. optical format. Excessive acquire and correlated a number of sampling allow optimum efficiency in low-light situations. At 50 Mpixels, the sensor has a most picture switch price of 30 fps. Utilizing 4-cell pixel binning, the OV50K40 delivers 12.5 Mpixels at 120 fps, dropping to 60 fps in HDR mode however with a fourfold improve in sensitivity.

To attain high-speed autofocus, the OV50K40 presents quad part detection (QPD). This permits 2×2 part detection autofocus throughout the sensor’s whole picture array for 100% protection. An on-chip QPD remosaic permits full 50-Mpixel Bayer output, 8K video, and 2x crop-zoom performance.
