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.
