Patent Images
1. A method for compressing frames of pixel data, comprising:
- organizing pixel data into groups of pixel data;
outputting compressed pixel data by an image sensor system using image compression on the groups of pixel data, the compressed pixel data outputted at a rate serviceable by an output bus of the image sensor system; and
transmitting, using the output bus, the compressed pixel data to a digital signal processor for processing into a video data format.

Abstract
Systems and methods are disclosed that capture and compress frames of pixel data. In an implementation, an image sensor chip is configured to convert light into pixel data and generate compressed pixel data at a variable compression rate including applying a transform to pixel data associated with a pixel category from a plurality of pixel categories. The variable compression rate is within an available bandwidth of an output bus configured to output the compressed pixel data.
