In recent developments, image sensors are no longer simply a means for collecting optical signals, but rather, are increasingly expected to serve as intelligent systems with surrounding configurations. Coded exposure (CE) is one of the methods applied in intelligent systems approaches, and various functions can be realized by the selection of the integration variable in the plenoptic function. High DR can be realized if the integration variable is time. A variety of means to achieve high DR have been proposed in the literature, for example, a method that provides a plurality of detection capacitors (LOFIC, [1]) or a method of preventing saturation by adding low-sensitivity pixels [2]. These methods often require an enlarged pixel size. Alternatively, high-speed readout like an array parallel stacked structure [3] is useful for integrating multiple frames to realize high DR. However, this leads to an increase in noise and needs faster readout to
