摘要： A motion information output portion acquires horizontal motion information concerning a line where the telop is present. From a signal of the current frame and motion-compensated signal components of frames which are present before and after the current frame. A decision information acquisition portion and a binarizing processing portion obtains a flag indicating whether each pixel of a screen is pixel at edge position of the telop. Based on this flag, an edge pixel extraction portion extracts pixel data of the edge position. A histogram processing portion uses this pixel data as a material to create a histogram for each item of data, thereby determining values of the pixel data corresponding to the telop from a class having a largest frequency. An extraction region selection portion obtains another flag indicating a line where the telop is present. An extraction portion extracts pixel data corresponding to the telop.

摘要： Apparatus and method for performing hierarchical coding without utilizing a delay circuit arranged separately from a memory for storing images. In the case where one second-layer pixel is formed from 2×2 first-layer pixels, three of the 2×2 first-layer pixels used to form the one second-layer pixel (excluding one final input pixel) are read out from a first-layer memory when the final input pixel is input. The three pixels read out are supplied to an adder which computes the sum thereof and supplies the sum value to an adder-subtracter. The adder-subtracter computes the sum of the sum value from the adder and the final input pixel so as to obtain the one second-layer pixel. Such second-layer pixel is supplied to a second-layer memory to be stored therein. The final input pixel is not stored in the first-layer memory.
