Abstract
Image deterioration when image data containing scanning lines of the previous and next fields mixed together by video editing is displayed is prevented. An inter-field scanning line interpolating unit superimposes scanning line data of the previous and next fields of interlacing image data in a video stream input from a tuner or a memory card to perform inter-field scanning line interpolation, and generates progressive image data corresponding to that video stream. An IP-conversion selection signal indicating a determination result whether or not the reliability of the video stream meets a predetermined level is input into a back-end from a CPU. A selector refers to the IP-conversion selection signal, and when the CPU determines that the reliability of the video stream is lower than the predetermined level, image data having undergone interpolation by the inter-field scanning line interpolating unit is selected as an image to be displayed.
