Electronic apparatus and driving method therefor

A method for driving an electronic device, the electronic device including

• a solid-state imaging device including
• a pixel array unit on which pixels are two-dimensionally arranged in a matrix form, the pixels including a photoelectric conversion unit that generates a signal charge according to an amount of light, a plurality of pixel transistors each of which transfers and reads the signal charge accumulated by the photoelectric conversion unit, and a charge accumulation unit that is shared between the plurality of photoelectric conversion units, and
• a scanning unit capable of driving the pixels during an exposure period in a manner that the exposure period concurrently begins for all of the pixels, and capable of driving the pixels in a manner that the exposure period also concurrently terminates for all of the pixels, and configured to selectively scan the pixels in order during a reading period, and
• a mechanical shutter configured to decide when the exposure period terminates in capturing a still image, the method comprising:
• configuring the plurality of photoelectric conversion units to photoelectrically light of a same color, the plurality of photoelectric conversion units sharing the charge accumulation unit,
• alternately arranging columns including pixels for photoelectrically converting green light and columns on which pixels for photoelectrically converting red light and pixels for photoelectrically converting blue light are arranged two by two in a column direction on the pixels,
• sharing the charge accumulation unit between two pixels of a same color adjacent to each other in the column direction,
• concurrently beginning an exposure period for all of the pixels in capturing a moving image by discharging the signal charge accumulated by the photoelectric conversion unit, concurrently terminating the exposure period for all of the pixels by transferring the signal charge generated and accumulated by the photoelectric conversion unit during the exposure period to the charge accumulation unit, and concurrently reading a signal charge of a pixel of a same color that shares the charge accumulation unit, and
• concurrently beginning the exposure period for all of the pixels in capturing a still image by discharging the signal charge accumulated by the photoelectric conversion unit, and concurrently terminating the exposure period for all of the pixels by closing the mechanical shutter.
