  • Publication number: 20210058572
    Abstract: An imaging apparatus includes an optical element configured to separate incident light into light components in at least two types of wavelength bands, and a plurality of imaging elements configured to receive the light components in the at least two types of wavelength bands separated by the optical element, respectively. When pixels that have undergone binning processing are regarded as one pixel on a group basis, pixels of at least one imaging element of the plurality of imaging elements are arranged with a shift of a half pixel in at least one direction of a horizontal direction and/or a vertical direction with respect to pixels of at least one other imaging element.

  • Publication number: 20210052149
    Abstract: An imaging apparatus includes an optical element configured to separate incident light into light components in at least three types of wavelength bands, and a plurality of imaging elements configured to receive the light components in the at least three types of wavelength bands separated by the optical element, respectively. At least one imaging element of the plurality of imaging elements has a function of further separating a wavelength band of light that has entered the imaging element into at least two types of wavelength bands.

  • Patent number: 10805553
    Abstract: According to one embodiment, an imaging apparatus includes an image sensor, image generation circuitry, calculation circuitry and superimposition circuitry. The image generation circuitry successively generates a first image and a second image. The calculation circuitry calculates a first parameter to allow brightness of the first image to be equal to or close to a predetermined value, and calculates a second parameter relating to brightness of the second image based on the first parameter and a predetermined ratio. The superimposition circuitry generates a composite image by superimposing the second image in which the brightness is adjusted using the second parameter onto the first image in which the brightness is adjusted using the first parameter.

  • Patent number: 10638077
    Abstract: An imaging device according to an embodiment includes an image sensor, and processing circuitry. The image sensor is a rolling-shutter type image sensor that includes a plurality of pixels that are arranged in a matrix and generate an electric signal due to light received and, on a frame-to-frame basis, repeatedly performs a process to sequentially start to conduct exposure on at least every line, starting from the first line of the pixels to the last line, and output the electric signal sequentially from the line for which exposure has been completed. The processing circuitry causes the pixels to receive light during only a period based on the blanking period that corresponds to the period from when the output of the electric signal from the last line is finished until the output of the electric signal from the first line is started. The processing circuitry generates images in accordance with the electric signal.

  • Patent number: 8937670
    Abstract: An imaging apparatus of an embodiment includes a captured video signal outputting unit, a data outputting unit, a supplement processing unit, and a video processing unit. The captured video signal outputting unit outputs a captured video signal related to video captured using an image capturing element. The data outputting unit outputs part of data related to the image capturing elements stored in a storage unit. The supplement processing unit receives the outputted part of the data related to the image capturing elements and uses the received part of the data related to the image capturing elements to perform supplement processing of the data. The video processing unit performs video processing of the outputted captured video signal using the supplement processed data and outputs a video signal.

  • Patent number: 7880774
    Abstract: An image recording apparatus and method that can store image information by thinning out latest image information at a low thinning-out ratio and thinning out old image information at a high thinning-out ratio. The image recording apparatus includes a recording unit that records plural pieces of image information received from the image pickup unit in a storage area together with recording date and time information of the respective pieces of image information; and a deleting unit that compares the present date and time and the recording date and time information recorded by the recording unit to calculate elapsed time of the respective pieces of image information and deletes the image information with the longer elapsed time at a thinning-out ratio higher than that of the image information with the shorter elapsed time.
