    摘要： A method of managing power consumption in a device such as a video image processing device for processing data from one or more pixels forming a frame of an image, the method comprising the steps of determining one or more regions of interest in the image, identifying one or more pixels located in said one or more regions of interest, processing the one or more identified pixels in a predetermined manner and switching off the power for at least part of the device when the transmitted pixel data are not amongst the one or more identified pixels for a predetermined period of time.

    摘要： A vignetting-like chromatic error, particularly found in image sensors having pixel dimensions of a few microns, is corrected by applying to each colour channel a gain factor which increases with the radial position of the pixel, and which is also controlled in dependence on ambient colour temperature.

    摘要： A light-sensitive pixel array (10) has an active area (12) and an additional area (14) of optically shielded pixels. A 'noise figure' is derived as a measure of the prevalence of noise in the image signal without being affected by the presence of moving detail in the image. The noise figure is derived by measuring the difference in output between the pixels of at least one pair of pixels in the optically shielded area (14) in one frame, repeating this in a subsequent frame, and subtracting one pixel pair difference from the other to give a difference of differences. In a preferred form, four pairs of pixels are used. The noise figure may be used to control digital signal processing of the image signal, such as be smoothing.
