On-chip upscaling and downscaling in a camera architecture
First Claim
1. A camera system, comprising:
- an image sensor chip configured to produce image data representative of light incident upon the image sensor chip;
an accelerator chip comprising;
a decimator configured to decimate the image data into a plurality of image sub-band components;
a downscale engine configured to downscale the image data using one or more of the image sub-band components; and
an upscale engine configured to upscale the image data using one or more of the image sub-band components; and
an image signal processor chip configured to process image data outputted by the image sensor chip or the accelerator chip and to output the processed image data.

Abstract
An image capture accelerator performs accelerated processing of image data. In one embodiment, the image capture accelerator includes accelerator circuitry including a pre-processing engine and a compression engine. The pre-processing engine is configured to perform accelerated processing on received image data, and the compression engine is configured to compress processed image data received from the pre-processing engine. In one embodiment, the image capture accelerator further includes a demultiplexer configured to receive image data captured by an image sensor array implemented within, for example, an image sensor chip. The demultiplexer may output the received image data to an image signal processor when the image data is captured by the image sensor array in a standard capture mode, and may output the received image data to the accelerator circuitry when the image data is captured by the image sensor array in an accelerated capture mode.
