Gentex Announces HDR CMOS Sensor with Per-Pixel Exposure Control

Marketwired: Gentex announces an HDR image sensor with per-pixel exposure control: "Automotive video for rear vision requires a camera with high dynamic range, which is the ratio between the brightest and darkest areas of a given scene. The challenge is to display the details in the darkest and brightest areas of a given scene simultaneously, without causing the display to "washout" due to bright light sources. The new Gentex camera meets this challenge in a unique way, with a proprietary CMOS (complementary metal oxide semiconductor) imager that delivers unprecedented dynamic range. The imager allows each individual camera pixel to choose its own exposure, self-adjusting so that the brightest and darkest areas of any given scene are clear and visible."

Gentex' Nov 2014 investor presentation gives a little bit more detail on the new HDR sensor:


  1. It sounds like the statement from Pixim: one camera per pixel...

  2. If 1 pixel can be considered as a group of pixels then there might me some patent related issues.

  3. What is the operating principle of this "super" sensor please?
