Motion estimation and detection in a camera system accelerator 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 image signal processor chip (“
ISP”
) configured to process the image data, the ISP comprising;
an input configured to receive the image data from the image sensor chip;
a decimator configured to decimate the received image data into a plurality of image sub-band components;
a motion detection engine configured to generate a motion map based on a first subset of the plurality of image sub-band components;
a motion estimation engine configured to generate a set of motion vectors based on the generated motion map and a second subset of the plurality of image sub-band components; and
an output configured to output one or more of the received image data and the set of motion vectors.

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.
