|1. (WO2015046045) IMAGING DEVICE AND IMAGING METHOD|
|Title:||IMAGING DEVICE AND IMAGING METHOD|
This invention provides an imaging device and an imaging method that make it possible to: acquire images corresponding to desired aperture values without the use of a mechanical diaphragm; acquire, in a single imaging operation, a plurality of images having different aperture values; and acquire high-quality images that exhibit reduced color mixing. This imaging device (1) is provided with an image sensor (14) and an electronic diaphragm unit. In the image sensor (14), in which a plurality of pixels that each have an organic layer that performs photoelectric conversion are arrayed two-dimensionally, each pixel is divided into a plurality of segments and has the following: an on-chip microlens (15) that forms, on said plurality of segments, pupil images from imaging optics (12); and readout units (16) that read out photoelectrically converted signals from the respective segments into which the pixel is divided. The electronic diaphragm unit, which electronically controls an aperture value, uses said aperture value to either select segments for the readout units (16) to read from or select a signal from among a plurality of segment signals read out by the readout units (16).
