摘要： A synchronization signal generating apparatus comprises a cycle setting section, a pulse masking section, and a pulse generating section. The pulse masking section outputs a pulse train based on an input pulse train and cycle information. The pulse generating section outputs a pulse train based on the pulse train and cycle information output from the pulse masking section. When a synchronization signal is switched from the state of being in synchronization with the pulse train input from the pulse masking section to the independent state, the cycle setting section switches the cycle information upon receiving a pulse of the pulse train for the first time since a cycle selection signal was changed. On the other hand, when the synchronization signal is switched from the independent state to the state of being in synchronization with the pulse train input from the pulse masking section, the cycle setting section switches the cycle information after receiving a pulse of the pulse train since the cycle selection signal was changed.

摘要： An inter-frame motion detector detects the presence or absence of motion between frames on the basis of judgment whether or not an inter-frame difference is not more than a set value. A vertical edge continuity detector calculates difference values between an object pixel and pixels above or below the object pixel in an inlaid picture, and detects whether or not there is horizontal continuity of an inter-field vertical edge on the basis of judgment whether or not the signs of the difference values are the same continuously over not less than a predetermined number of pixels, in the horizontal direction, including the object pixel. When it is detected that there is no motion between frames, and it is detected that there is horizontal continuity of the inter-field vertical edge, it is judged that a picture is in a completely still state.

摘要： A binarizer binarizes a video signal input from an A/D converter and a video signal output from a line memory using an average luminance value provided from a detection window video signal processor as a threshold value, and outputs a binary pattern. A reference pattern generater generates a plurality of reference patterns. An angle detector compares the binary pattern with each of the plurality of reference patterns, and outputs the angle of a matched reference pattern as angle information. An arc shape detector outputs the edge angle information of a picture based on a combination of the angle information of an interpolation scanning line including an object interpolation pixel and the angle information of interpolation scanning lines above and below the interpolation scanning line.

摘要： A vertical interpolation circuit interpolates an interpolated pixel with pixels located on upper and lower vertical positions, and outputs a vertical interpolated value. An oblique averaging part averages pixels obliquely located with respect to the interpolated pixel on the basis of an oblique edge angle signal, and outputs the result of calculation as an oblique average. An oblique difference absolute value operation part calculates the absolute value of the difference between the values of the pixels obliquely located with respect to the interpolated pixel on the basis of the oblique edge angle signal, and outputs the result of calculation as an oblique difference absolute value. A mixing part outputs the vertical interpolated value, the oblique average or a mixed value thereof as an interpolated pixel value on the basis of the oblique difference absolute value.

摘要： An image processing method and apparatus for converting an original image by performing a pixel number conversion on the original image at a predetermined pixel number conversion rate in at least one of a column direction and a row direction in a matrix that has been specified. A character judging step determines whether each of a plurality of areas making up the original image is a character part or not. When it is determined that image has a character part, a pixel number conversion procedure is performed so that the lines within the original image are converted into lines with the same line width in the converted image. Alternatively, areas that are judged a character part can use an alternative pixel number conversion procedure so that a barycenter in the original image is maintained after the pixel number conversion.
