example 1

[0102] As an example, a case where only the ISO sensitivity is different between the first imaging condition and the fourth imaging condition, and the ISO sensitivity of the first imaging condition is 100 and the ISO sensitivity of the fourth imaging condition is 800 is taken as an example. The pixel P of interest in the main image data is obtained under the first imaging condition (ISO sensitivity 100). In this case, the processing unit 33b of the image processing unit 33 uses the image data of the reference pixels Pr1 to Pr6 of the main image data obtained under the first imaging condition among the reference pixels Pr and the first processed image data obtained at the ISO sensitivity of 100. Reference pixels Pr7, Pr8 ( Figure 7 The image data of (d)) is used for image processing. The processing unit 33b does not use the image data of the reference pixels Pr7 and Pr8 obtained under the fourth imaging condition (ISO sensitivity 800) among the reference pixels Pr obtained un...

[0104] As an example, the case where only the shutter speed is different between the first imaging condition and the fourth imaging condition, and the shutter speed of the first imaging condition is 1 / 1000 second and the shutter speed of the fourth imaging condition is 1 / 100 second . The pixel P of interest in the main image data is obtained under the first imaging condition (shutter speed 1 / 1000 second). In this case, the processing unit 33b of the image processing unit 33 uses the image data of the reference pixels Pr1 to Pr6 of the main image data obtained at a shutter speed of 1 / 1000 second among the reference pixels Pr, and the image data of the reference pixels Pr1 to Pr6 obtained at a shutter speed of 1 / 1000 second. Image processing is performed with reference to the image data of the pixels Pr7 and Pr8 of the image data for the first processing. The processing unit 33b does not use the image data of the reference pixels Pr7 and Pr8 of the main image data obtained unde...

example 3

[0106] As an example, the case where only the frame rate is different (the charge accumulation time is the same) between the first imaging condition and the fourth imaging condition, and the frame rate of the first imaging condition is 30 fps and the frame rate of the fourth imaging condition is 60 fps . The pixel of interest P in the main image data is obtained under the first imaging condition (30 fps). In this case, the processing unit 33b of the image processing unit 33 uses the image data of the reference pixels Pr1 to Pr6 of the main image data obtained at 30 fps and the reference pixels of the first processing image data obtained at 30 fps among the reference pixels Pr. Pr7, Pr8 image data for image processing. The processing unit 33b does not use the image data of the reference pixels Pr7 and Pr8 of the main image data obtained under the fourth imaging condition (60 fps).

[0107] On the other hand, when the first imaging condition applied to the pixel P of interest ...

Abstract

This imaging device is provided with: an imaging element which has an imaging region for imaging a subject, said region having arranged therein first pixels, which output a signal generated from a photoelectrically converted charge, and second pixels, different from the first pixels, which output a signal generated from a photoelectrically converted charge; a setting unit which sets an imaging condition of a first region of the imaging region, in which the first pixels are arranged, and sets an imaging condition of a second region of the imaging region, different from the first region, in which the second pixels are arranged; a selection unit which selects pixels for use in interpolation of the first pixels in the first region in which the first imaging condition was set by the setting unit, said selection being made from the second pixels in the second region in which a second imaging condition different from the first imaging condition was set by the setting unit and the second pixels in the second region in which a third imaging condition different from the second imaging condition was set by the setting unit; and a generation unit which generates an image of at least part of the subject imaged in the imaging region using a signal which, outputted from the first pixels in the first region in which the first imaging condition was set, is interpolated by means of the signal outputted from the second pixels selected by the selection unit.

Description

technical field [0001] The present invention relates to an imaging device and an image processing device. Background technique [0002] There is known an imaging device equipped with an imaging element capable of setting different imaging conditions for each area of ​​the screen (see Patent Document 1). However, when using image data generated in areas with different imaging conditions, there is a problem that it cannot be the same as when using image data generated in areas with the same imaging conditions. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2006-197192 Contents of the invention [0006] According to the first aspect of the present invention, the imaging device includes: an imaging element having an imaging area for imaging a subject, and the imaging area is an area in which first pixels and second pixels different from the first pixels are arranged. an area in which the first pixel outputs...
