Abstract

An electronic device includes a display panel and image processing circuitry. The image processing circuitry receives input image data corresponding to an image to display on the display panel, modifies the input image data by executing a first context task (e.g., lower priority task), and receives a context switch request. The image processing circuitry also pauses modification of the input image data by pausing execution of the first context task and then switches to modifying the input image data by executing a second context task (e.g., higher priority task).
