Deformed example 1

[0071] In the above embodiment, the imaging timing of the lower photoelectric conversion layer 32 is delayed by half a frame, but it may be delayed by 1 / 3 frame to obtain a moving image with a frame rate three times the imaging rate. In this case, the first frame, the fourth frame, the seventh frame, ... are generated by imaging with the upper photoelectric conversion layer 31, and the second, fifth, eighth, ... generated by shooting. The remaining 3rd frame, 6th frame, 9th frame, . For example, the image of the third frame may be generated from the image of the second frame and the image of the fourth frame. That is, of the three consecutive frames, one of them is generated based on the imaged result of the upper photoelectric conversion layer 31 , one of them is generated based on the imaged result of the lower photoelectric conversion layer 32 , and the remaining frames are generated by interpolation. In addition, frames other than the first frame among three consecutive ...

Deformed example 2

[0073] In the above-described embodiment, odd-numbered frames are generated based on imaging results of the upper photoelectric conversion layer 31 , and even-numbered frames are generated based on imaging results of the lower photoelectric conversion layer 32 . Conversely, odd-numbered frames may be generated based on imaging results of the lower photoelectric conversion layer 32 , and even-numbered frames may be generated based on imaging results of the upper photoelectric conversion layer 31 .

Deformed example 3

[0075] Such as Figure 9 As schematically shown in (a), the imaging element 21 may have two horizontal output circuits 33a, 33b, and the readout of each pixel of the upper photoelectric conversion layer 31 and the readout of each pixel of the lower photoelectric conversion layer 32 may be performed simultaneously. readout. At this time, one horizontal output circuit 33 a corresponds to the upper photoelectric conversion layer 31 , and the other horizontal output circuit 33 b corresponds to the lower photoelectric conversion layer 32 . By adopting such a structure, for example, it takes time to read due to a large number of rows, such as Figure 9 As shown in (b), the present invention can be applied even when the readout period Ta of the upper photoelectric conversion layer 31 and the readout period Tb of the lower photoelectric conversion layer 32 overlap.

Abstract

The present invention provides an imaging device, comprising: a plurality of first pixels, which have a plurality of color components, and photoelectrically convert incident light to generate a first signal; Light is photoelectrically converted to generate a second signal; and a drive unit that reads out the first signal from the first pixel and reads out the second signal from the second pixel at a timing different from the timing at which the first signal is read out.

Description

technical field [0001] The present invention relates to imaging devices. Background technique [0002] Conventionally, it has been known that when a moving image is captured in a dark place using an imaging device that captures a moving image, the exposure time needs to be prolonged, and the frame rate decreases. For example, Patent Document 1 describes an image processing device that synthesizes past frames so that the sum of exposure times becomes a target exposure time, thereby reducing frame rate drop. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2013-26950 Contents of the invention [0006] In the prior art, since images of a plurality of frames are superimposed to apparently increase the frame rate, there is a problem that the influence of noise increases. [0007] According to the first aspect of the present invention, the imaging device includes: a plurality of first pixels having a plurality ...
