Patent ID: 8233744

Claim:
An image enlargement apparatus that receives a low-resolution image and outputs a high-resolution image of a higher resolution than the low-resolution image, said image enlargement apparatus comprising: an interpolation unit configured to receive the low-resolution image, and generate an interpolation image having the number of pixels of the high-resolution image; a feature value analysis unit configured to analyze a feature value of the low-resolution image, and output the feature value for each pixel of the high-resolution image; a correction amount calculation unit configured to receive the feature value outputted by said feature value analysis unit and the low-resolution image, and calculate a correction amount for each pixel of the high-resolution image; a synthesis unit configured to generate a first high-resolution image, by synthesizing the correction amount calculated by said correction amount calculation unit and the interpolation image generated by said interpolation unit; and a re-correction unit configured to generate a corrected second high-resolution image by re-correcting the first high-resolution image outputted by said synthesis unit using the feature value generated by said feature value analysis unit, and output the generated second high-resolution image from said image enlargement apparatus.
