| Zusammenfassung: | PROBLEM TO BE SOLVED: To solve the following problem: a dynamic range of an imaging unit has been limited to a narrow range.SOLUTION: The imaging element includes: a photoelectric conversion unit for converting light into charges; a storage unit for storing a first signal generated by charges of the photoelectric conversion part; and a control unit for controlling to store charges for a second signal generated later than a first signal stored in the storage unit in the photoelectric conversion unit on the basis of the first signal. In the imaging element, the storage unit may store a third signal generated by the first signal and the second signal.SELECTED DRAWING: Figure 8
【課題】撮像ユニットのダイナミックレンジは、狭い範囲に限られていた。【解決手段】撮像素子は、光を電荷に変換する光電変換部と、光電変換部の電荷により生成された第１信号が格納される格納部と、格納部に格納された第１信号に基づいて、光電変換部において、第１信号よりも後に生成される第２信号のための電荷蓄積を行うように制御する制御部と、を備える。上記撮像素子において、格納部は、第１信号と第２信号とにより生成される第３信号が格納されてもよい。【選択図】図８ |
