On-Chip Image Sensor Data Compression

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