摘要： Multiple images are captured where the exposure times for some of the images overlap and the images are spatially overlapped. Charge packets are transferred from one or more portions of pixels after particular integration periods, thereby enabling the portion or portions of pixels to begin another integration period while one or more other portions of pixels continue to integrate charge. Charge packets may be binned during readout of the images from the image sensor. Comparison of two or more images having different lengths of overlapping or non-overlapping exposure periods provides motion information. The multiple images can then be aligned to compensate for motion between the images and assembled into a combined image with an improved signal to noise ratio and reduced motion blur.

摘要： A CMOS image sensor or other type of image sensor comprises a sensor wafer and an underlying circuit wafer. The sensor wafer comprises a plurality of photosensitive elements arranged in respective positions of a two-dimensional array of positions in which a subset of the array positions do not include photosensitive elements but instead include diffusion regions each of which is shared by two or more of the photosensitive elements. The sensor wafer is interconnected with the circuit wafer utilizing a plurality of inter-wafer interconnects coupled to respective ones of the shared diffusion regions in respective ones of the array positions that do not include photosensitive elements. The image sensor may be implemented in a digital camera or other type of image capture device.

摘要： A CMOS image sensor or other type of image sensor comprises a pixel array and a signal generator coupled to the pixel array. The pixel array comprises a plurality of pixels each having a photosensitive element coupled to a transfer gate. The signal generator is configured to generate a transfer gate signal for application to at least one of the transfer gates. The transfer gate signal has at least an on state voltage level and first and second off state voltage levels, with the first off state voltage level typically having a higher magnitude than that of the second off state voltage level. In an illustrative embodiment, the second off state voltage level is utilized during a readout operation in order to reduce dark current in floating diffusion regions of the pixel array.

摘要： A thin lens consists of a first optical element which comprises a first refracting surface, wherein incoming light passes through the first refracting surface on a first optical axis. A reflecting surface changes a direction of the incoming light from the first optical axis to a second optical axis. Incoming light on the second optical axis passes through a second refracting surface. A second optical element comprises a first refracting surface, wherein incoming light passes through the first refracting surface on the second optical axis. A reflecting surface changes a direction of the incoming light from the second optical axis to a third optical axis. Incoming light on the third optical axis passes through a second refracting surface. The third optical axis is approximately parallel to, and in opposite direction from, the first optical axis.
