Abstract

A digital imaging sensor includes an array of pixels. A subset of the pixels in the array has reduced photosensitivity in comparison to other pixels in said array. A controller operates to control an integration time of the array of pixels such that a first integration time of the subset of pixels is longer than a second integration time of the other pixels in the array. Such an image sensor is particularly useful for sensing light sources that are not illuminated continuously.

First claim

What is claimed is:

1. A digital imaging sensor, comprising:
an array of pixels arranged in columns and rows, wherein each column and row includes a plurality of pixels, wherein a subset of the plurality of pixels in a given row of said array has reduced photosensitivity in comparison to other pixels in said given row of said array;
and a control circuit configured to control an integration time of said array of pixels such that a first integration time of said subset of pixels…
