Abstract: Provided is a color camera that captures using environmental light, a monochrome camera that captures using infrared light, a signal processing unit that processes a signal of a color image output from the color camera and a signal of a monochrome image output from the monochrome camera, a storage unit that stores alignment information generated from a color image and a monochrome image captured in a state of sufficient environmental light, an alignment unit that performs an alignment based on alignment information to match positions of a subject shown in a color image and a monochrome image captured in a state of insufficient environmental light, and an image synthesis unit that acquires color information from the aligned color image and performs color conversion to colorize the monochrome image using the color information.

Abstract: An imaging device includes an imaging section including an imaging sensor section of a rolling shutter system, a condition designator that sets an imaging condition using first auxiliary light which is non-visible light as an imaging condition for the imaging section and an imaging condition using visible light with the first auxiliary light as non-emitted light, and alternately designates the imaging condition and a light emission condition of the first auxiliary light at a cycle of at least two frames in a time division basis, a first light emitter that emits the first auxiliary light according to the light emission condition; and an image composer that composes a non-visible light image captured by the imaging section under the imaging condition using the first auxiliary light during a first period in which the first auxiliary light is emitted and a visible light image captured by the imaging section under the imaging condition using the visible light during a second period subsequent to the first period.

Abstract: An imaging device is provided with a condition designating unit which designates, by time division, imaging conditions for capturing an image, and light emission conditions for emitting auxiliary light, an imaging section which captures an image including a subject according to the imaging conditions, a light emitting unit which emits auxiliary light with respect to the subject according to the light emission conditions, and an image composer which composes a first image that is captured under a first imaging condition during a light emission period in which the auxiliary light is emitted and a second image which is captured under a second imaging condition during a non-light-emission period which is continuous to the light emission period and in which the auxiliary light is not emitted, in which quality of an image which is captured in a low illumination environment is improved.

Abstract: To increase the processing speed when median processing in the time direction is performed on color images, pixel values of each channel (R, G and B values) are extracted from multiple temporally consecutive frame images; subsequently, identifiers (index numbers) corresponding to frame images from which the pixel values are extracted are assigned to the pixel values; subsequently, a sorting process is performed on a set of pixel values of one channel (G values) to obtain an identifier assigned to a median value thereof; subsequently, a pixel value to which an identifier identical with that assigned to the median value is assigned is selected as a median value of each channel; and subsequently, a median image is generated on the basis of the median value of each channel obtained for each pixel.

Abstract: An object of the present disclosure is to display a captured image and a shake corrected image thereof on the same screen. An imaging device is provided and has a configuration provided with a correction amount calculator that calculates a correction amount for correcting image shake in a frame image, a shake corrected image generator that generates a shake corrected image in which the image shake is corrected by performing a geometrical conversion with respect to a current frame image based on the correction amount, and a synthesized image generator that generates a synthesized image in which the current frame image and the shake corrected image are disposed on the same screen.

Abstract: An image processing device for synthesizing a plurality of mutually adjacent and partially overlapping pieces of image data, includes a boundary portion selection unit which, from boundary portions of adjacent image data, selects the boundary portion for calculating an image correction value, a correction value calculator which calculates the image correction value of the boundary portion selected by the boundary portion selection unit, and an image correction unit which, in the boundary portion selected by the boundary portion selection unit, performs image correction of the boundary portion using the image correction value calculated by the correction value calculator, and which, in the boundary portion that has not been selected by the boundary portion selection unit, performs image correction using the image correction value calculated in the past.

Abstract: Imaging device has a configuration provided with: a primary correction amount calculator that calculates a primary correction amount for correcting image shake in a current frame image based on a physical shake amount of the imaging device; a secondary correction amount calculator that calculates a secondary correction amount for correcting a search shake amount between the current frame image and a previous frame image which is one frame image before the current frame image; a correction amount selector that selects at least one of the primary correction amount and the secondary correction amount based on at least one of an imaging condition and the primary correction amount; and an image converter that performs a geometrical conversion with respect to the current frame image based on at least one of the primary correction amount and the secondary correction amount which is selected by the correction amount selector.
