Abstract: This disclosure provides systems, methods, and devices for image signal processing that support efficient cache usage in an image processing system. In a first aspect, a method of image processing includes storing, by an image processor, a first portion of a first stripe of a first frame in a cache, the first portion of the first stripe overlapping a second portion of a second stripe of the first frame, reading, by the image processor, a third portion of the second stripe from a memory, reading, by the image processor, the first portion of the first stripe from the cache, and processing, by the image processor, the second stripe using the first portion of the first stripe and the third portion of the second stripe. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for image signal processing that support improved correction of motion artifacts within image frames. In a first aspect, a method of image processing includes receiving a first image frame and a second image frame, determining a motion map indicating motion of objects within the first and second image frames. Additionally, motion hotspots may be identified within the second image frame based on the motion map. A temporal filtering process may be applied to portions of the second image frame located within motion hotspots to generate a corrected image frame. Other aspects and features are also claimed and described.

CPC classification number: H04N5/265 , G06K9/6202
Abstract: Methods and apparatuses are disclosed for processing a plurality of captured image frames. An example method may include receiving a first image frame and a second image frame from a camera sensor. The example method may also include determining a first portion of the second image frame with a temporal difference from a corresponding first portion of the first image frame, wherein a second portion of the second image frame is without a temporal difference from a corresponding second portion of the first image frame. The example method may also include processing the second image frame, including processing the first portion of the second image frame, and preventing processing the second portion of the second image frame.

Abstract: Systems and techniques are provided for conserving resources when performing motion estimation. An example process can include determining, based on an input image and a reference image, motion vectors identifying motion between the input image and the reference image; determining whether the motion indicated by the motion vectors is below a first threshold; based on a determination that the motion indicated by the motion vectors is below the first threshold, refraining from determining a local motion between the input image and the reference image; determining a transform matrix based on the motion vectors and without using a local motion between the input image and the reference image; and adjusting the input image based on the transform matrix.
