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 comprising luminance values beyond a predetermined edge determination reference value in a 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 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 frame; a resolution convertor configured to generate a temporary high-resolution image with the second resolution by converting a resolution of the frame from the first resolution to the second resolution; an image quality improvement module configured to enhance image quality of pixels in the temporary high-resolution image corresponding to a region other than the detected flat region, and 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 control at least one of the texture determination reference value and the flat region determination reference value based on a predetermined rule.
