Abstract: In an imaging apparatus, a pupil division optical system includes a first pupil transmitting light of a first wavelength band and a second pupil transmitting light of a second wavelength band different from the first wavelength band. An imaging device is configured to capture an image of light transmitted through the pupil division optical system and a first color filter having a first transmittance characteristic and light transmitted through the pupil division optical system and a second color filter having a second transmittance characteristic partially overlapping the first transmittance characteristic, and output the captured image. A processor is configured to generate a monochrome correction image or a correction image by correcting a value that is based on components overlapping between the first transmittance characteristic and the second transmittance characteristic for the captured image.

Abstract: In an imaging apparatus, a processor is configured to generate at least one of a first monochrome correction image and a second monochrome correction image as a monochrome correction image. The first monochrome correction image is an image generated by correcting a value based on components overlapping between a first transmittance characteristic and a second transmittance characteristic for a captured image having components based on the first transmittance characteristic. The second monochrome correction image is an image generated by correcting a value based on components overlapping between the first transmittance characteristic and the second transmittance characteristic for the captured image having components based on the second transmittance characteristic. The processor is configured to superimpose a mark on the monochrome correction image or a processed image generated by processing the monochrome correction image on the basis of point information.

Abstract: In an endoscope device, a control unit brings an imaging device into an operation in a first read-out mode. In the first read-out mode, the imaging device reads out pixel signals from a plurality of pixels in a first time. After an instruction for the measurement of a subject is generated, the control unit brings the imaging device into an operation in a second read-out mode. In the second read-out mode, the imaging device reads out the pixel signals from the plurality of pixels in a second time. The second time is shorter than the first time. The control unit causes an imaging condition switching unit to switch imaging conditions on the basis of an operation of the imaging device in the second read-out mode.

Abstract: In an imaging apparatus, a processer is configured to output a first monochrome correction image and a second monochrome correction image. The first monochrome correction image is an image generated by correcting a value based on components overlapping between a first transmittance characteristic and a second transmittance characteristic for a captured image having components based on the first transmittance characteristic. The second monochrome correction image is an image generated by correcting a value based on components overlapping between the first transmittance characteristic and the second transmittance characteristic for the captured image having components based on the second transmittance characteristic. The processer is configured to perform image processing on a processing target image out of the first and second monochrome correction images such that the difference of image quality between the first and second monochrome correction images becomes small.

Abstract: An image-processing device is provided with: a pattern-matching portion that performs pattern matching between a first image and a second image acquired before the first image and that outputs a motion vector between the images and an evaluation value that indicates the accuracy of the motion vector; a recursive noise-reduction portion that outputs a noise reduction image, which is the first image to which noise reduction has been applied, and that performs noise reduction in which an image based on the first image and an image based on the noise reduction image formed in the past are mixed in accordance with a predetermined recursion amount; and a controlling portion that controls a recursion amount in the recursive noise-reduction portion on the basis of the motion vector and the evaluation value output by the pattern-matching portion and a gain that is applied to the first image to adjust a brightness thereof.
