Abstract: From a pixel array where imaging pixels are arranged, pixel signals of respective columns on a selected row are read in parallel in a horizontal blanking period of a horizontal period. The pixel signals of the respective columns are output to horizontal signal lines in an effective period of the horizontal period via charge integrating amps provided respectively for the columns, i.e., provided respectively for vertical signal lines, and are thereby transferred horizontally. In the charge integrating amps, it is possible to enter a standby state while holding the pixel signals by a holding voltage. Furthermore, in the charge integrating amps, a reference potential for precharging feedback capacitors for amps at the time of a reading operation is automatically controlled based on a black level. Furthermore, pixel signals from the respective charge integrating amps are horizontally transferred in parallel using a plurality of horizontal signal lines.

Abstract: The present invention is an electronic imaging device and method of expanding its dynamic range. The invention comprises modifying the imaging device by providing a comparator and reset trigger circuit located at or near the site of each of the pixels. The comparator triggers a reset mechanism when the voltage in the charged pixel reaches a reference voltage. During the global exposure time each individual pixel can be self-reset several times, depending on the intensity of the radiation incident upon it. At the end of the global exposure time, each pixel contains only the “residual value” of voltage that remains from the last individual self-reset to the end of the global integration time. An algorithm is implemented, which estimates and determines the number of resets undergone by each pixel during the global exposure time. From this number of resets the algorithm is able to reconstruct the true image.
