Image conversion device, image conversion model learning device, method, and program

Abstract

A low-resolution image can be converted into a high-resolution image in consideration of differential values of the images. A learning conversion unit 22 inputs a first image for learning to a conversion processing model for converting the first image into a second image having a higher resolution than the first image to acquire the second image for learning corresponding to the first image for learning. Then, a differential value calculation unit 24 calculates a differential value from the acquired second image for learning, and calculates a differential value from a correct second image corresponding to the first image for learning. Then, the learning unit 26 causes the conversion processing model to learn by associating the calculated differential value of the second image for learning with the differential value of the correct second image.
