摘要： An image signal corresponding to infrared light is separated from an image signal corresponding to visible light, the visible light including an infrared light signal, even when imaging is performed while performing the infrared light irradiation. An exposure control unit alternately repeats a first frame in which an exposure time is set to a predetermined first exposure time and a second frame in which the exposure time is set to a second exposure time longer than the first exposure time. An infrared light irradiation control unit performs irradiation of infrared light in a predetermined infrared light irradiation period which is equal to or less than an aggregate period of the first frame and the second frame. An image signal acquisition unit acquires a first image signal which is the image signal in the first frame and a second image signal which is the image signal in the second frame. An extraction unit extracts a visible light intensity per unit time and an infrared light intensity per unit time from the first image signal and the second image signal. A generation unit generates an image signal corresponding to visible light and an image signal corresponding to the infrared light on the basis of the visible light intensity per unit time and the infrared light intensity per unit time.

摘要： Provided is a method and apparatus for converting, to a digital video signal, an analog video signal capable of having a variety of resolutions. A video reception apparatus determines a format of an analog video signal by sampling the analog video signal. The video reception apparatus converts the analog video signal to a digital video signal based on the determined format. A comb filter is used to separate a color difference signal and a luminance signal from the digital video signal, and the digital video signal is reconfigured using the luminance signal and the color difference signal.

摘要： An adaptive temporal motion filter for a video decoder system operates in an infinite impulse response (IIR), a max or a bypass mode. The adaptive temporal motion filter includes an adaptive time constant control module and a filter gain module. A gain factor of the filter gain module is varied by the adaptive time constant control module for every pixel in a current composite video signal. The adaptive time constant control module selects a variable gain for the filter gain module based on the motion magnitude, motion polarity and chroma luma status of the pixel.
