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: In an imaging apparatus, two pupils of a pupil division optical system transmits light of a first wavelength band and light of a second wavelength band. An amount of components of the first wavelength band in first transmittance characteristics and second transmittance characteristics is more than an amount of components of the second wavelength band in the first transmittance characteristics and the second transmittance characteristics. An amount of components of the second wavelength band in third transmittance characteristics is more than an amount of components of the first wavelength band in the third transmittance characteristics. A processor is configured to generate a color image including a first signal that is based on the first transmittance characteristics as a first channel and a second signal that is based on the second transmittance characteristics as a second channel and a third channel.

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: An endoscope device includes an endoscope including, in a tip end thereof, an imaging device, a first optical system, and an optical element. The optical element is disposed at any one of a first position on an optical path of the first optical system and a second position away from the optical path of the first optical system and is configured to switch between states of light incident on the imaging device. In addition, the endoscope device includes a detector and a processor. The detector is configured to detect movement of the optical element. The processor is configured to determine whether or not the optical element moves from the first position or the second position on the basis of the movement. The processor is configured to control a position of the optical element on the basis of a result of determination executed by the processor.

Abstract: In a measurement device, a controller causes an imaging unit to generate a plurality of first pictures based on a first image and a plurality of second pictures based on a second image. The controller determines whether or not there is blurring on the basis of at least two of the plurality of first pictures. The controller determines whether or not there is blurring on the basis of at least two of the plurality of second pictures. The controller causes a measurement unit to perform measurement when the controller determines that there is no blurring in first picture blurring determination and second picture blurring determination.

Abstract: In a measuring device, a second objective optical system is arranged to have a parallax with respect to a first objective optical system. An imaging unit captures a first subject image formed through the first objective optical system at a first imaging timing and captures a second subject image formed through the second objective optical system at a second imaging timing different from the first imaging timing. A virtual image generating unit generates a virtual image based on the first subject image acquired in a case in which the imaging unit is assumed to capture the first subject image at the second imaging timing. A measurement processing unit measures a shape of a subject on the basis of a second image based on the second subject image and the virtual image.
