General Description

The onsemi AR0246 is a stacked 1/4−inch back side illuminated

(BSI) CMOS active−pixel digital image sensor with a pixel array of

1920 (H) x 1080 (V). The sensor has enhanced NIR response. It

captures images in either linear or high dynamic range modes with a

rolling shutter readout, and includes sophisticated camera functions

such as binning, windowing and both video and single frame modes. It

is designed for both low light and high dynamic range performance.

AR0246 can combine on chip up to three exposures and compand to

12−bit HDR output (eHDR) or it could provide line interleaved output

of two exposures to support off chip HDR (LI HDR) in an ISP chip. It

could also provide enhanced Dynamic Range (eDR) from single

exposure. The AR0246 produces extraordinarily clear, sharp digital

pictures, and its ability to capture both continuous video and single

frame enhanced NIR response makes it the perfect choice for security

applications.
