Abstract
Embodiments of the present application automatically utilize parallel image captures in an image processing pipeline. In one embodiment, image processing circuitry concurrently receives first image data to be processed and second image data to be processed, wherein the second image data is processed to aid in enhancement of the first image data.
Claims26
An image capture device, comprising:
- a hardware processor;
- and
- an image processing circuitry that concurrently receives first image data to be processed and second image data to be processed, wherein:
- the second image data is processed to aid in enhancement of the first image data;
- the image processing circuitry comprises an imaging pipeline for processing a plurality of image data captured from at least one image sensor;
- the imaging pipeline features two parallel paths for processing the plurality of image data;
- the first image data is processed at full-resolution on a first parallel path and the second image data is processed at a down-scaled resolution on a second parallel path;
- and
- the second parallel path comprises a hardware pipeline that extracts data used in decoding the first image data with the first parallel path, wherein the second parallel path is shut down after passing extracted data to the first parallel path without storing the extracted data in memory, wherein the first parallel path comprises a hardware pipeline.

An image processing method, comprising:
- receiving a first image data to be processed and a second image data to be concurrently processed;
- and
- processing the second image data to aid in enhancement of the first image data, wherein:
- the first image data and the second image data are processed in parallel pipeline paths, the first image data being processed at full-resolution on a first parallel path and the second image data being processed at a down-scaled resolution on a second parallel path;
- the first parallel path comprises a hardware pipeline;
- the second parallel path comprises a hardware pipeline that extracts data used in decoding the first image data with the first parallel path;
- and
- the second parallel path is shut down after passing extracted data to the first parallel path without storing the extracted data in memory.
5 more elements
An image processing method comprising:
- capturing first image data with a first image sensor;
- downscaling the first image data to produce second image data;
- receiving the first image data to be processed and the second image data to be concurrently processed;
- processing the second image data to aid in enhancement of the first image data,
- wherein the first image data and the second image data are processed in parallel pipeline paths, wherein the first image data is processed at full-resolution on a first parallel path and the second image data is processed at a down-scaled resolution on a second parallel path,
- wherein the first image data is processed and encoded using data extracted from processing of the second image data;
- and
- deleting the second image data and extracted data after encoding the first image data.
