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： In an imaging apparatus, a function whose value increases in time is used as a threshold electric-signal level, and an electric-signal level of a photoreceptor element is compared with the threshold electric-signal level. Even if a light received by the photoreceptor element has a low luminance, the electric-signal level of the photoreceptor element crosses the threshold electric-signal level in a short time, allowing calculation of the amount of optical energy received by the photoreceptor element. Furthermore, when an object having a region where brightness changes in time and also having a region with a low luminance is imaged, imaging interval is changed in accordance with luminance. Accordingly, information regarding how the brightness of the object is rapidly changing in time can be obtained more precisely, and an image can be output without making a projection image of the dark region completely black.

摘要： The invention provides a new method and apparatus for NTSC and PAL image sensors which employs fusion of adjacent row pixel charge samples to generate image data for a row. A variety of fusion schemes are possible for fusing the pixel signals from the adjacent rows. The rows of pixels are scanned so that each scan takes an odd row signal sample and, in some cases, an adjacent even row signal sample when specified conditions are met. One sampled row of the two adjacent rows integrate an image with a first integration period while the other adjacent row integrates an image with a second integration period.
