摘要： A video signal processing apparatus processes a video signal which is obtained by carrying out a dot interlaced scanning in terms of four fields so that picture element data which correspond to one field and in which the picture element data of first and third dot interlaced fields (or second and fourth dot interlaced fields) alternately exist on each line are transmitted during a time period of one field. The video signal processing apparatus comprises a luminance difference detecting part and an interpolation part. The luminance difference detecting part performs a detecting operation to detect a luminance difference between two luminance data which are belonged respectively to two mutually adjacent picture elements in the same line and are among the picture element data which correspond to one field. When the luminance difference detecting part detects a luminance difference between the two luminance data during two or more consecutive detecting operations, the interpolation part replaces one luminance data out of the two luminance data in which the luminance difference is detected by the other luminance data.

摘要： A method of compressing and decompressing a multidimensional image. A video data including luminance data distributed at least in two-dimension is compressed to be codes. The codes are decompressed to reproduce the video data. A specific number of representative pixels are extracted from a plurality of pixels consisting of the digital signal of video data. Texture data is also extracted from the digital signal of video data. The representative pixels and the texture data are coded. And then the coded representative pixels and the texture data are decoded. The video data is reproduced using the decoded representative pixels and the texture data.

摘要： PURPOSE: To improve the reliability and the cost effectiveness of the compression/expansion device by limiting extraction of the feature points of lower importance to improve the compressibility and controlling the signal processing time to finish it within a prescribed time in a compression/expansion mode. CONSTITUTION: The image information is converted into the digital signals by an ADC 10 and inputted to an isolated pixel deletion means 16. Then the pixels whose luminance are not equal to those of all pixels adjacent to a two-dimensional image are regarded as noises, and the feature points generated by the noises are reduced. An adaptive luminance contour group generation means 12 analyzes the luminance value distribution of the isolated pixel interpolation image information to decide the luminance value B G. At the same time, the number of intersecting points are counted against the image luminance function. This luminance value is slightly increased and decreased to decrease the number of intersecting points and then to suppress the luminance contours which are generated by the change of luminance of lower importance. An encoder means 15 encodes the luminance value of the luminance contour feature points and also their position information group and outputs the encoded and compressed image data at a prescribed transmission speed.

摘要： PURPOSE:To attain highly efficient picture expansion by extracting a contours of specific luminance in a mixed function picture and using them for interpolating luminance information for picture expansion so as to absorb an error when a picture is sent between different types of equipments. CONSTITUTION:A contour tracer extracts a contour in picture information and decides a characteristic point and sends characteristic point information to a reception decoding circuit 8 via a transmission line. The reception decoding circuit 8 decodes a coded signal and gives the result to a luminance function reproduction device 9. A search address generator 31 of the luminance function reproduction device 9 generates an address of picture elements other than a picture element of a characteristic point stored in a picture memory 29 and retrieves a picture element at a characteristic point closest to the picture element and describes a mark thereto. An interpolation face discrimination circuit 32 extracts three characteristic points for deciding interpolation from an applied characteristic point name. An interpolation value write circuit 33 calculates an interpolated value in an internal area from the three characteristic points to fill a luminance value of picture elements other than those of the characteristic point existing in the internal area.
