An imaging unit images an object in a state where an infrared projector projects infrared light. The imaging unit generates an imaging signal. A determination unit analyzes the relationship between the amount of environmental visible light and the amount of infrared light. A controller controls the imaging device, according to the relationship between the amount of environmental visible light and the amount of infrared light, analyzed by the determination unit.

Imaging device, image signal processing method, and image signal processing program

An imaging unit causes each exposure corresponding to one frame period of respective second image signals in a first mode, and causes each exposure in divided sections of one frame period of the respective second image signals under different imaging conditions in a second mode. An image processing unit generates frames of respective first image signals based on each imaging signal read out in such a manner as to correspond to each exposure corresponding to one frame period in the first mode, and generates frames of the respective first image signals based on each imaging signal read out in such a manner as to correspond to each exposure of the divided sections in the second mode. An image output unit sequentially outputs frames of the second image signals set to a signal format common to the first mode and the second mode.

Imaging device, method for controlling imaging device, and control program

A first projection controller of an imaging device controls a first infrared projector, capable of projecting infrared light with multiple wavelengths, to selectively project the infrared light with the multiple wavelengths. An imaging unit of the imaging device images an object in a state where the first infrared projector projects the infrared light. A synchronous signal transmitter transmits outward a synchronous signal for synchronizing a timing of projecting infrared light from a second infrared projector controlled by a second projection controller included in another imaging device other than the imaging device, with a timing of projecting the infrared light from the first infrared projector controlled by the first projection controller.

An imaging unit includes a color filter in which filter elements of R, G and B are arranged in a plane thereof. The imaging unit captures an object in a state where infrared light with three frequencies assigned to R, G and B are projected so as to generate first to third frames. A synthesizing unit in a pre-signal processing unit arranges pixel data for the three primary colors including pixel data for R in the first frame, pixel data for G in the second frame and pixel data for B in the third frame in such a manner as to have the same array as the filter elements in the color filter, so as to generate synthesized image signals synthesized in one frame. A demosaicing unit subjects the frame of the synthesized image signals to demosaicing so as to generate frames of the three primary colors.

Imaging device, image processing device, image processing method, and image processing program

An image processing unit is configured to generate pixel data for a predetermined color in an intermediate mode implemented based on pixel data obtained from a predetermined region in a light receiving element when an object is captured in a state where infrared light is projected. The image processing unit is configured to generate the pixel data for the predetermined color in a night-vision mode implemented based on pixel data obtained from a wider region than the predetermined region in the light receiving element when the object is captured in the state where the infrared light is projected. The mode stitching unit is configured to switch, depending on conditions, between a state where an image output unit outputs an image signal generated in the intermediate mode and a state where the image output unit outputs an image signal generated in the night-vision mode.
