固体撮像装置およびその駆動方法、電子機器
Document Type and Number:
Japanese Patent JP6731725
Kind Code:
B2
Abstract:
A solid-state imaging device 10 capable of extending a dynamic range by combining a plurality of read-out signals has a signal processing part 710 which, when combining the plurality of read-out signals, selects at least one signal which becomes necessary for the combination in accordance with a result of a comparison between at least one read-out signal among the plurality of read-out signals (high conversion gain signal HCG, low conversion gain signal LCG) with a threshold value (Joint Thresh), applies the selected signal to the combinational processing, and thereby generates the combined signal extended in the dynamic range, and the signal processing part can dynamically change the threshold value. By this configuration, it is possible to smoothly switch a plurality of signals to be combined irrespective of variations in individual units etc., possible to realize a higher dynamic range while suppressing deterioration of images, and consequently possible to realize a higher quality of image.
