摘要： Film-originated video detection is performed on an input video signal in each of regions into which an entire screen is divided. Based on the detection result, a case where there is not film-originated video is separated from a case where film-originated video covers the entire screen. When both a film region and a non-film region are contained, film-originated video detection is performed in sub-regions into which a region which has been determined to be a film region is subdivided. Based on the detection result, it is determined whether or not all the sub-regions are film regions. The determination is repeatedly performed until it is determined that all sub-regions are film regions. If it is determined that all sub-regions are film regions, a film-originated video region is determined, and the process is ended. Thus, a film-originated video region can be accurately detected in a screen containing film-originated video and non-film-originated video.

摘要： An image processing method includes a difference extraction step (103) of outputting a frame difference signal from an input image signal and from an image signal that has been frame-delayed so that a base value of noise of the film image is acquired from a portion of the film image of a 2-3 pull-down scheme where a signal that is identical every five fields, an integration step (107) of accumulating output signals of the difference extraction step, a detection step (106) that a difference of the entire frames is small based on the output signal of the difference extraction step, and an acquisition step (108) of acquiring, as a noise amount, an integrated value of the frame in the integrated step at timing when it is detected in the detection step that a difference of the entire frames is small. With this, noise is detected by the image processing method. A noise reduction step (113) is carried out using a result of the detection of noise.

摘要： In a semiconductor device of the present invention, a clock is not changed instantaneously but it is changed over maximum N+1/M clocks (N: integer not less than 2) by shifting delay cells stepwisely to make the phase state of a previous reference signal and the phase state of a present reference signal coincide with each other, whereby the clock is synchronized with the reference signal with accuracy, and the duty of the output clock is kept constant. According to the semiconductor device of the present invention, it is possible to prevent the duty of the clock from being discontinuous when a signal whose reference signal does not coincide with the clock is inputted and reset is made to a rising edge of this reference signal.

摘要： A contour correcting device which includes a plurality of delay elements which delay an input video signal, a pixel-selection-control-signal generation circuit, a pixel selection circuit which selects outputs of the plurality of delay elements in response to outputs of the pixel-selection-control-signal generation circuit, a high-pass filter operation circuit and an adder circuit which adds an operation result of the high-pass filter operation circuit to the input video signal. When the pixel selection circuit extracts a contour component in a boundary portion between a horizontal video effective period and a period other than the horizontal video effective period of the input video signal, the pixel selection circuit replaces pixel data in the period other than the horizontal video effective period among pixel data input to the high-pass filter operation circuit, with pixel data at an edge-point of the horizontal video effective period.
