Abstract: Systems and techniques are described for performing foveated sensing. In some aspects, a method (e.g., implemented by an image sensor) can include capturing sensor data for a frame associated with a scene, obtaining information corresponding to a region of interest (ROI) associated with the scene, generating a first portion (having a first resolution) of the frame corresponding to the ROI, generating a second portion of the frame having a second resolution, and outputting (e.g., to an image signal processor (ISP)) the first portion and the second portion. In some aspects, a method (e.g., implemented by an ISP) can receive, from an image sensor, sensor data for a frame associated with a scene, generating a first version (having a first resolution) of the frame based on an ROI associated with the scene, and generating a second version of the frame having a second resolution (lower than the first resolution).

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, the second exposure time greater than the first exposure time; determining at least one of: that one or more pixels of the first image has a pixel value below a first threshold value; or that one or more pixels of the second image has a pixel value above a second threshold value; preventing image processing on the one or more pixels based on the determination; replacing, based on preventing image processing on the one or more pixels, one or more pixel values of the one or more pixels with one or more replacement pixel values; and outputting the first or the second image, the first or the second image including the one or more replacement pixel values.

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: Disclosed are systems, apparatuses, processes, and computer-readable media to capture images with subjects at different depths of fields. For instance, a method of processing image data includes obtaining a first image captured using an image sensor with a first exposure. The method may further include obtaining a second image captured using the image sensor with a second exposure. The method may include compressing the second image based on a comparison of the second image with the first image and storing the compressed second image in a memory. The method may further include obtaining the compressed second image from the memory and decompressing the compressed second image based on a difference between the compressed second image and the first image. The method may further include generating a combined image at least in part by combining the first image and the second image.
