PROBLEM TO BE SOLVED: To provide a video signal processing device, a video display device, and a video display system capable of reducing occurrences of flickers when a video is observed with shutter glasses.SOLUTION: A video signal processing unit 41 performs high frame rate conversion processing to an input video signal Din so that the frame rate of each video (right-eye video and left-eye video) becomes more than twice to generate a video signal D1. Then, the video signal D1 after the high frame rate conversion processing is alternately switched for each video in time division to perform video display. A shutter control unit 42 performs a control operation for shutter glasses 6 to perform an opening/closing operation synchronized with display timing of each video after the high frame rate conversion processing. In this way, a cycle of the opening/closing operation of the shutter glasses 6 becomes short (the frequency of the opening/closing operation becomes high).

PROBLEM TO BE SOLVED: To favorably generate interpolated image data in frame interpolation processing in a multi-screen display mode.SOLUTION: A speed detection unit 115, when time-series image data Vs is data with a child screen superimposed thereon, substantially stops speed detection in a child screen area. An interpolation processing unit 117 can generate interpolated image data of a parent screen without being affected by image movements in the child screen area. A film image determination unit 116, when the time-series image data Vs is data with the child screen superimposed thereon, does not reference detected information on regularity of the child screen area at the time of determination. The film image determination unit 116 can determine whether the time-series image data (parent screen) is film image data without being affected by the image movements in the child screen area, and the interpolation processing unit 117 can reliably perform generation processing of the interpolated image data corresponding to the film image data (film image interpolation).

PROBLEM TO BE SOLVED: To improve the picture quality of a picture signal after interpolation when a predetermined picture signal is superimposed on the picture signal before interpolation. SOLUTION: An MPU (Micro Processing Unit) 31 acquires OSD (On Screen Display) information, which is information about the position of a predetermined picture signal in an input picture signal; wherein the predetermined picture signal is superimposed on the input picture signal. An interpolation processing portion 72 specifies an interpolation stop region to be not applied with interpolation according to at least one motion vector in a signal between input picture signals, based on the OSD information. The interpolation processing portion 72 interpolates and outputs a signal between input picture signals in regions other than the interpolation stop region, based on a motion vector of the input picture signal; wherein the signal between input picture signals is a picture signal in an arbitrary time between the input picture signal and a previous input picture signal one place before the input picture signal. The present invention is applicable to a television receiver, for example. COPYRIGHT: (C)2009,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a video processing apparatus and method, capable of reducing the deterioration of image in frame rate conversion due to noises caused by image compression. SOLUTION: The video processing apparatus uses an arrangement position of an original image included in a time series image signal as a reference and calculates an amount of correction that indicates an arrangement position of an interpolated image signal to be interpolated in the time series image signal based on at least the data rate of the time series image signal. Based on the calculated amount of correction, the video processing apparatus sets creation time of the interpolated image signal to be interpolated in the time series image signal. In this case, when the data rate has changed such that, when it becomes less than a predetermined threshold, it further becomes a smaller value than the threshold, the amount of correction is calculated so that the arrangement position will be drawn closer to that of the original image, and when the data rate has changed such that, when it becomes less than the threshold, it becomes closer to the threshold, the amount of correction is so calculated as to draw the arrangement position closer to an equal position of the original image divided at equal intervals.

PROBLEM TO BE SOLVED: To provide an image information transferring device and image information transferring method for preventing an occurrence of excessive information to be eliminated without being used regardless of being transferred from an image information storing part when the image information storing part transfers image information to a display device in order to display the image information of a 4: 2: 0 format stored in the image information storing part such as a memory on the display device. SOLUTION: When a transfer control means transfers luminance information of a 4: 2: 0 format stored in a storing means, first color difference information, and second color difference information to an image signal generating means, the transfer control means transfers luminance information constituting a first line, the first color difference information, the second color difference information, and luminance information constituting a second line as one transfer unit, to the image signal generating means.

Abstract:
PROBLEM TO BE SOLVED: To form a phase locked loop (PLL) in a digital circuit. SOLUTION: A synchronizing signal extracted from a video signal is gated by an AND gate 3 through a separator circuit 1, and the gated synchronizing signal is supplied to a phase comparator circuit 4. This compared output is inputted through a loop filter 5 to an oscillation circuit 6 composed of a counter and this oscillated output is inputted to the phase comparator circuit 4, so that the PLL can be formed. Further a mask signal generating circuit 10 generates that mask signal from the output of this oscillation circuit 6 and a counter 13 counts how many times the synchronizing signals are continuously absent during the period of this mask signal. When this number of times exceeds a prescribed value, the synchronizing signal from the video signal is extracted and corresponding to this signal, the counter consisting of the oscillation circuit is reset. Thus, the stable and speedy PLL and synchronizing separator circuit are constituted.

PROBLEM TO BE SOLVED: To provide a video processing apparatus in which judders are less apt to be perceived. SOLUTION: The video processing apparatus is for enhancing the time resolution, by generating an interpolation image signal, based on a motion vector between time series image signals input continuously. The video processing device includes: a feature change detector for detecting a change in a predetermined feature between the time series image signals; a generation time setter for setting a generation time for the interpolation image signal; and an interpolation signal generator for generating the interpolation image signal, corresponding to the generation time set by the generation time setter. When it is desired to set the generation time, after the time series image signal having a feature change detected by the feature change detector, the generation time setter sets a generation time closer to the generation time for one of the time series image signals which are disposed before or after the generation time.

Abstract:
PROBLEM TO BE SOLVED: To improve image quality of an image signal after subjected to interpolation, when superimposing a predetermined image signal on the image signal, before being subjected to interpolation. SOLUTION: A microprocessing unit (MPU) 31 accepts a command, to start or end superimposing of a predetermined image signal on an input image signal. When the superimposition start or end command is accepted, an interpolation processing section 72 detects the motion vector of the input image signal, on which superimposing of the predetermined image signal is started or ended, and interpolates and outputs an interpolation signal, on the basis of the motion vector without having to depend on the reliability of the motion vector as a whole. The present invention is applicable to television receivers. COPYRIGHT: (C)2009,JPO&INPIT
