Camera configuration in a camera system accelerator architecture

摘要

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.

1. A camera system, comprising:
an image sensor chip configured to produce image data representative of light incident upon the image sensor chip during a capture interval; an image capture accelerator chip (“ICA”) comprising:
an input configured to receive the image data from the image sensor;a compression engine configured to decimate the received image data into a plurality of image sub-band components; andone or more outputs configured to output the received image data and an image sub-band component; and an image signal processor chip (“ISP”) with a first input and a second input, the ICA coupled between the image sensor chip and the ISP and configured to:
receive the processed image data at the first input;receive the image sub-band component at the second input;process the received sub-band component; andreconfigure the camera system based on the processing of the received sub-band component.
