    Abstract: In one example, an apparatus comprises a pixel cell array and a controller formed within a semiconductor package. The pixel cell array is configured to: generate, at a first time and based on first programming signals received from the controller, a first image frame; transmit the first image frame to a host processor; and transmit the first image frame or a second image frame to the controller, the second image frame being generated at the first time and having a different sparsity of pixels from the first image frame. The controller is configured to receive second programming signals from a host processor, the second programming signals being determined by the host processor based on the first image frame; update the first programming signals based on the second programming signals; and control the pixel cell array to generate a subsequent image frame based on the updated first programming signals.

    Abstract: A multi-mode sensor assembly is described. The sensor assembly includes a first die and a second die. The first die includes a pixel array composed of color pixels that detect light in one or more color channels and sparse pixels. The color pixels and the sparse pixels are arranged to form macro pixels, and each macro pixel includes a respective subset of the color pixels and a respective subset of the sparse pixels. The second die is positioned below and coupled to the first die. The second die includes an analog-to-digital converter (ADC) array that is communicatively coupled to the sparse pixels such that each subset of the sparse pixels has a single corresponding ADC in the ADC array.

    CPC classification number: H04N23/73

    Abstract: In one example, an apparatus includes an array of pixel cells and a peripheral circuit. Each pixel cell of the array of pixel cells includes: a memory to store pixel-level programming data and measurement data, and light measurement circuits configured to, based on the pixel-level programming data from the control memory, perform a light measurement operation to generate the measurement data, and to store the measurement data at the data memory. The peripheral circuit is configured to: receive a pixel array programming map including pixel-level programming data targeted at each pixel cell; extract the pixel-level programming data from the pixel array programming map; and transmit the pixel-level programming data to each pixel cell of the array of pixel cells for storage at the memory of the each pixel cell and to individually control the light measurement operation and a generation of the measurement data at the each pixel cell.

    Abstract: In one example, an apparatus comprises a photodiode, a charge storage unit, and a processing circuits configured to: transfer overflow charge from the photodiode to the charge storage unit to develop a first voltage; compare the first voltage against a first ramping threshold voltage to generate a first decision; generate, based on the first decision, a first digital value; transfer residual charge from the photodiode to the charge storage unit to develop a second voltage; compare the second voltage against a static threshold voltage to determine whether the photodiode saturates to generate a second decision; compare the second voltage against a second ramping threshold voltage to generate a third decision; generate, based on the third decision, a second digital value; and output, based on the second decision, one of the first digital value or the second digital value to represent an intensity of light received by the photodiode.

    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.
