The Problem
Quite frequently photographers encounter the annoying experience, of practical inability to shoot a scene with a wide range of brightness levels.  The modern camera, as perfect as it may seem, lacks the necessary dynamic range for scenes, with complex and "not ideal" lighting conditions.  The problem results, too frequently, in the need to abandon a picture and/or a video stream due to the lack of the right capturing angle, or to settle for a poor compromise on image quality.
The need for better sensitivity in order to capture the fine details of dark areas photographed can be solved by image sensors with larger pixel sizes, longer image exposure times and with wider iris opening. These solutions increase the need for image sensors that must have additional grey levels per pixel.  These extra sensitive sensors are called wide dynamic range (WDR) sensors.  Cameras with WDR and low light sensitivity that is capable of producing, high quality image(s) that shows the fine details of the darker image areas, yet without over exposure of the brightest image areas.  These sensors are in dire need for surveillance, automotive, machine vision and other applications.  The Mega pixel race and the reduction of pixels' dimensions, increase the need for sensitivity and WDR solutions also for common sensors integrated in Digital Stills cameras and Cam phones.

With all the known marvels of the digital technology, no solution is rendered for extremely bright areas adjacent to relatively dark areas in the photo scene.

Bright's solution was designed to extend the dynamic range (DR) of CMOS image sensor based cameras, by a large factor.  The solution is based on its high quality Multi-Resets (MR) method and trades expensive sensor's hardware "real estate" with low cost software.  The Camera’s DR is adapted, automatically, to fit a specific scene resulting in low noise level at all light intensities, high quality images, short setup time and higher compression ratios. 

In MR, the sensor modification allows independent discharging of every pixel, whenever saturation is reached. The pixel continues the process of photons acquisition and discharge till the end of the exposure interval.  Typical MR implementation requires a counter per pixel to store the number of discharges per pixel during frame integration.  A single exposure time is required to capture the image details of the darkest areas of the scene. Bright's solution uses the same reset mechanism as MR but without the counters, looses the number of discharges per pixel and therefore must recover these values by post analysis.  Bright's solution is not bounded to the counter's number of bits, do not require their large real estate and therefore enjoys from low cost implementations.
