Problems solved by technology

Therefore, it is difficult to adopt a pixel sharing system, whereby there is a problem in the size reduction of pixels
[0006] In the solid-state image capture device disclosed in Japanese Unexamined Patent Application Publication No. 2009-268083, since signal charges are also accumulated in the CCD type charge holding capacitor portion and the floating diffusion portion, it is difficult to adopt a pixel sharing system

Abstract

An electronic apparatus includes: a pixel array section in which pixels including photoelectric conversion sections that generate signal charges corresponding to amounts of light, charge accumulation sections that receive the signal charges from the corresponding photoelectric conversion sections and that are shared thereby, and pixel transistors that read out the signal charges generated by the corresponding photoelectric conversion sections and that are shared thereby are two-dimensionally arranged in a matrix; a solid-state image capture device including a scanner that can drive the pixels so that exposure periods of all of the pixels are simultaneously started, that can drive the pixels so that the exposure periods of all of the pixels are simultaneously ended, and that sequentially selects and scans the pixels in readout periods; and a mechanical shutter that determines an end of the exposure periods for still-image shooting.

Description

technical field [0001] The present disclosure relates to electronic devices with solid state image capture devices. In particular, the present disclosure relates to electronic devices having solid-state image capture devices with global shutter functionality. In addition, the present disclosure relates to a driving method for the electronic device. Background technique [0002] Typically, a CMOS (Complementary Metal Oxide Semiconductor) solid-state image capture device employs a system for sequentially reading out, row by row, signal charges generated and accumulated by light-receiving portions in pixels arranged in a two-dimensional matrix. In this case, the exposure timing at the light receiving portion of each pixel is determined by the start and end of readout of signal charges. Therefore, the exposure timings at the respective pixels are different from each other. Thus, when such a CMOS solid-state image capture device is used to capture an image of a fast-moving sub...
