Abstract:
1. An information processing apparatus configured to execute resolution enhancement in order to generate a second moving image signal with a second resolution from a first moving image signal with a first resolution lower than the second resolution, the information processing apparatus comprising: an edge detection module configured to detect an edge region in which luminance values are changed to values beyond a predetermined edge determination reference value in a to-be-processed frame of the first moving image signal with the first resolution; a texture detection module configured to detect a texture region where a change in luminance value is substantially regular and continuous in the to-be-processed frame based on a predetermined texture determination reference value; a flat region detection module configured to detect a flat region where a change in luminance value is smaller than a predetermined flat region determination reference value in the to-be-processed frame; a resolution convertor configured to generate a temporary high-resolution image with the second resolution by converting a resolution of the to-be-processed frame from the first resolution to the second resolution; an image quality improvement module configured to execute first image quality improvement processing in order to enhance image quality of pixels in the temporary high-resolution image corresponding to a region other than the detected flat region, and to execute second image quality improvement processing in order to sharpen the pixels in the temporary high-resolution image corresponding to the detected edge region not in the detected texture region; and a controller configured to adjust the texture determination reference value in order to limit a time of the resolution enhancement per frame within a predetermined time.
