Abstract: Systems and techniques are described herein for processing frames. For example, a process can include obtaining a current frame from a sequence of frames, the current frame associated with a first bit depth resolution and a reference frame preceding the current frame associated with the first bit depth and resolution. The process can include determining a difference between a first pixel value of the current frame and a second pixel value of the reference frame, the first pixel value and the second pixel value associated with a corresponding first pixel position. The process can include outputting a first portion of the determined difference as a first output value and, based on a determination that the determined difference does not exceed a maximum magnitude of a second bit depth, outputting an indication that the determined difference does not include a second portion associated with the first pixel position.

Abstract: Systems and techniques are provided for generating an HDR image. An example method can include obtaining a first image and a second image that has an exposure that is greater than an exposure of the first image; setting pixels of the first image that are below a minimum threshold to a minimum value and pixels of the second image that are above a maximum threshold to a maximum value; retrieving, from memory, a compressed version of the first image with the pixels set to the minimum value and a compressed version of the second image with the pixels set to the maximum value; generating a first decompressed image including the first image with the pixels set to the minimum value and a second decompressed image including the second image with the pixels set to the maximum value; and generating an HDR image based on the first and second decompressed images.

Abstract: Systems and methods for processing pixels of an image at an imaging hardware device are provided. The method comprises receiving a first pixel. The method further comprises determining a content parameter of the first pixel. The method further comprises, based on the determining, storing the content parameter of the first pixel. The method further comprises initiating a computation of a first output pixel value for the first pixel. The method further comprises receiving a second pixel. The method further comprises determining a content parameter of the second pixel. The method further comprises determining that the second pixel is redundant in response to the content parameter of the second pixel matching the stored content parameter of the first pixel. The method further comprises, in response to the matching, setting a second output pixel value for the second pixel to be equal to the first output pixel value.

Abstract: This disclosure provides systems, methods, and devices for image signal processing that support compression of phase detection (PD) data. In a first aspect, a method of image processing includes receiving image data and first phase detection data corresponding to the image data; determining a first channel of the first phase detection data and a second channel of the first phase detection data; and coding the first phase detection data to determine second phase detection data by separately coding the first channel and the second channel. Other aspects and features are also claimed and described.

Abstract: Techniques are described herein for processing image data. For instance, a technique can include obtaining a first image having a first exposure time and a second image having a second exposure time that is greater than the first exposure time. The technique can further include determining at least one of: that a first pixel of the first image has a first pixel value below a first threshold value; or that a second pixel of the second image has a second pixel value above a second threshold value; suppressing at least one of the first pixel or the second pixel based on the determination so as to prevent storing the first pixel or the second pixel; replacing the suppressed first pixel or second pixel based on a another pixel value; and outputting the first image or the second image, the first image or the second image including the another pixel.

Abstract: An example image processor for processing pixels includes processing circuitry configured to determine that a first subset of input bits of a current pixel are the same as a first subset of input bits of a previously processed pixel, selectively bypass processing the first subset of input bits through a first pipeline based on the determination, output a first subset of output bits of the previously processed pixel as a first subset of output bits of the current pixel based on the determination, and merge the first subset of output bits of the current pixel with a second subset of output bits of the current pixel generated through a second pipeline from a second subset of input bits of the current pixel.
