摘要： A system and method for performing frequency compensation in a video digital cameral utilizing a time-indexed multiple sampling technique is presented. The frequency compensation removes distortion from the digital image signal captured by the video digital camera as compared with a human-perceived image signal.

摘要： A system and method for performing low-power analog-to-digital conversion in digital imaging system utilizing a time-indexed multiple sampling technique is presented. The analog-to-digital converter is switched off when the digital image signal resulting from an exposure time selected from a plurality of exposure times satisfies a threshold value.

摘要： An image (or other light) sensor has a reflective element under each light-sensing element. The reflective element is positioned to reflect incident light that passes through the light-sensing element without being absorbed, back towards the light-sensing element for a second chance at being absorbed. The present invention increases the effective quantum efficiency of each light-sensing element without having to increase the thickness of the absorption region within the light-sensing element. In one embodiment, each reflective element is a discrete mirror that is positioned within the sensor packaging adjacent to (e.g., below) the integrated image sensor. In another embodiment, each reflective element is an integral part of the integrated circuit that contains the image sensor, such as a light-reflecting region formed within the substrate below the corresponding light-sensing element.
