Abstract: A monolithic integrated circuit including an image sensor for capturing image information; at least one analog to digital convertor for converting analog signals corresponding to the image information into digital image data; and an image processor, the image processor including a low-pass filter for filtering the image data, thereby to generate filtered image data.

Abstract: A monolithic integrated circuit comprising an image processor configured to make each of a series of frames of image data available to a host processor, the image processor being configured to receive a first message from the host processor indicative of the host processor not requiring further access to the image data prior to a subsequent frame synchronisation signal; in response to the first message, causing at least part of the integrated circuit to enter a low power mode; and in response to a frame synchronisation signal, cause the part of the integrated circuit in the low power mode to exit the low power mode.

Abstract: A monolithic integrated circuit including an image sensor for capturing image information; at least one analog to digital converter for converting analog signals corresponding to the image information into digital image data; and a first framestore for storing frames of the digital image data.
