摘要： An optical sensor, for sensing a sensing frame corresponding to a flicker period of ambient light, comprising: a pixel array, configured to perform N times of exposure operations via at least one pixel of the pixel array in N exposure time intervals to generate N sub-frames, wherein a summation of the N exposure time intervals equals to a sensing interval and the sensing interval is less than or identical to a first flicker period. The optical sensor adds the N sub-frames to generate a summing sub-frame. The sensing frame comprises the summing sub-frame. The adding operation can also be performed to digital signals generated from the sub-frames. The influences caused by the fluctuation of ambient light can be neutralized, since the frame or portion of the frame is sensed at least twice at different phases of a single flicked period. By this way, the conventional flicker issue can be improved.

摘要： A photoelectric conversion apparatus includes a pixel, an A/D conversion portion and an output circuit. The pixel includes first and second photoelectric conversion portions and an accumulation portion configured to accumulate a signal charge in a location other than the photoelectric conversion portions. The A/D conversion portion is configured to perform A/D conversions on signals based on signal charges generated in the photoelectric conversions. The output circuit reads out first and second signals based on first and second signal charges accumulated in the first and second photoelectric conversion portions during an electric charge accumulation period and a third signal based on a third signal charge generated in the second photoelectric conversion portion and accumulated in the accumulation portion during the electric charge accumulation period. Conversion periods for analog-to-digital conversion to be performed on at least two of the first, second, or third signals have different lengths.

摘要： An imaging device includes an imaging unit including a plurality of pixels, respectively including photoelectric converters and charge accumulation nodes that accumulate signal charge. The imaging unit outputs image data based on signals corresponding to the signal charge accumulated in the charge accumulators. The imaging device includes an image processing unit that processes the image data output by the imaging unit. The imaging unit sequentially outputs a plurality of pieces of image data in one frame period by performing readout nondestructively. The image processing unit generates difference image data by determining a difference between two pieces of image data, selects output image data from initial image data and the difference image data, and combines the output image data and normal readout image data included in the plurality of pieces of image data, to generate combination-result image data.

摘要： The dynamic range of a pixel is increased by using selective photosensor resets during a frame time of image capture at a timing depending on the light intensity that the pixel will be exposed to during the frame time. Pixels that will be exposed to high light intensity are reset later in the frame than pixels that will be exposed to lower light intensity.
