    Abstract: An image signal conversion apparatus for converting a SD signal (525i) into a HD signal (525p or the like). In the image signal conversion section, the SD signal is converted into the HD signal, and the image is displayed on the display section. A class code CL indicating a class of a subject pixel of the HD signal is obtained by detecting a space class and a motion class from tap pixel data corresponding to the subject pixel of HD signal which is selectively fetched from a SD signal. The controller loads coefficient data of each class according to the selected resolution into the coefficient memory from the information memory bank when the user selects the resolution. In the calculation circuit pixel data of the subject pixel of the HD signal is calculated using an estimating equation based on the tap data xi corresponding to the subject pixel of the HD signal selectively fetched from the SD signal in the tap selection circuit and the coefficient data read in class code CL from the coefficient memory.

    Abstract: An object of the present invention is to make it possible to detect the mixture state of an image. An area specifying unit 103 specifies, in correspondence with image data, a mixed area in which foreground object components forming a foreground object and background object components forming a background object are mixed and a non-mixed area formed of a foreground area consisting of only the foreground object components and a background area consisting of only the background object components. A mixture-ratio calculator 104 estimates, based on the ratio of the width of the mixed area in a predetermined direction with respect to the moving direction of the foreground object, the width of the mixed area being specified by the area information, to the distance from the position of a designated pixel to the edge of the mixed area in the predetermined direction, the mixture ratio indicating the ratio of the foreground object components and the background object components of the designated pixel. The present invention is applicable to an image processing apparatus.
