US 7,257,278 B2 · Image sensor for capturing and filtering image data

Abstract

An integrated image sensor for acquiring and processing electrical signals representative of an object comprising a photosite array configured to convert light into the electrical signals, an A/D converter configured to convert the electrical signals into digital data, and logic integral with the image sensor configured to scale the digital data by a non-integer-scaling factor. A method for acquiring and processing image data with an integrated image sensor comprising the steps of capturing, via the image sensor, the image data representative of an image, scaling, via the image sensor, the image data by a non-integer value, and outputting from the integrated image sensor scaled image data.

Dependent claims

An image sensor for acquiring and processing image data, the sensor comprising:

an integrated circuit (IC) chip;
a photosite array configured to convert light into electrical signals;
a converter configured to convert the electrical signals into digital data;
and
scaling logic configured to apply spatial image resolution scaling to the digital image data, wherein the photosite array and the logic reside on the IC chip, and wherein the spatial image resolution scaling is defined by a scaling factor that is function of a selected image resolution, a selected zoom factor, and a total number of pixels in the photosite array.
