Filed:

May 24, 2011

Appl. No.:

13/114694

Inventors:

Peter Alan Levine - West Windsor NJ, US
Rui Zhu - East Brunswick NJ, US

Assignee:

SRI International - Menlo Park CA

International Classification:

H01L 27/146

US Classification:

2502081

Abstract:

A non-linear conversion capability within an on-chip, per-column analog-to-digital converter (ADC) is provided to expand a compressed analog signal such that the resulting digital output that has a predetermined (linear or non-linear) mapping with respect to input brightness level of an incoming light signal to a row of pixels. The predetermined mapping may also be provided by a non-linear amplifier coupled to a linear or non-linear ADC and a resulting compressed non-linear digital representation at the output of the ADC is substantially linearized by an on-chip or an off-chip look-up table (LUT).

International Classification:

H04N 5/374

Abstract:

An imaging sensor for low light level color imaging includes an array of pixels. Each pixel has a first pixel portion that has a first photosensitive area and is responsive to light in a panchromatic spectral range and a second pixel portion that has a second photosensitive area and is responsive to light in a sub-band spectral range. The first photosensitive area is greater than the second photosensitive area and the sub-band spectral range is narrower than and contained within the panchromatic spectral range. The first and second pixel portions of each pixel are independently addressable. The imaging sensor is beneficial for applications requiring wide dynamic range, low light sensitivity and color discrimination, and enables improved object discrimination and scene interpretation.
