Abstract: An apparatus comprises a first photodiode, a second photodiode, a quantizer, a memory, and a controller configured to: set a first exposure period in which the first photodiode generates a first charge; set a second exposure period in which the second photodiode generates a second charge, the second exposure period being set based on the first exposure period and at least one of: a first time associated with a read out operation of the memory to a second apparatus, or a second time associated with a quantization operation by the quantizer; perform, using the quantizer, the first quantization operation of the first charge to generate a first digital output; and perform, using the quantizer, a second quantization operation of the second charge to generate a second digital output.

Abstract: A depth estimation system is described capable of determining depth information using two images from two cameras. A first camera captures a first image and a second camera captures a second image, both images including a plurality of light channels. A scan direction is selected from a plurality of scan directions. For the selected scan direction, along each of a plurality of scanlines, the system compares pixels from the first image to pixels from the second image. The comparison is based on calculating a census transform for each pixel in the first image and a census transform for each pixel in the second image. This comparison is used to determine a stereo correspondence between the pixels in the first image and the pixels in the second image. The system generates a depth map based on the stereo correspondence.

Abstract: In one example, a mobile device comprises: a physical link; a plurality of image sensors, each image sensor being configured to transmit image data via the physical link; and a controller coupled to the physical link, whereby the physical link, the plurality of image sensors, and the controller form a multi-drop network. The controller is configured to: transmit a control signal to configure image sensing operations at the plurality of image sensors; receive, via the physical link, image data from at least a subset of the plurality of image sensors; combine the image data from the at least a subset of the plurality of image sensors to obtain an extended field of view (FOV); determine information of a surrounding environment of the mobile device captured within the extended FOV; and provide the information to an application to generate content based on the information.
