Abstract:
1. An information processing apparatus configured to enhance a resolution in order to convert from a moving picture signal with a first resolution to a moving picture signal with a second resolution higher than the first resolution, the apparatus comprising: an edge detection module configured to detect edges in a frame of the moving picture signal with the first resolution in accordance with a predetermined edge determination reference value; an edge number counting module configured to count a number of edges detected; a resolution convertor configured to convert a resolution of the frame from the first resolution to the second resolution, in order to generate a provisional high-resolution image of the second resolution; a corresponding pixel point detection module configured to detect corresponding pixels in he provisional high-resolution image, which correspond to the detected edges; an image quality enhancement module configured to sharpen the detected corresponding pixels in the provisional high-resolution image; and a controller configured to calculate a maximum edge number at which the information processing apparatus is able to complete the resolution enhancement for one frame within a target process time, and to vary the edge determination reference value based on the detected edge number and the maximum edge number, in order to suppress the detected edge number to the maximum edge number or smaller.
