IMAGE QUALITY-ENHANCEMENT LEARNING DEVICE AND IMAGE QUALITY-ENHANCEMENT DEVICE

摘要

To provide an image quality-enhancement learning device and an image quality-enhancement device capable of efficiency achieving high image quality enhancement with a small processing load.SOLUTION: An image quality-enhancement learning device includes: region extraction means 11 which extracts an adjacent region (c) including a pixel A of interest and a peripheral region (b) including the pixel A of interest from a resolution conversion image (a); approximate pixel specifying means 12 which acquires a pixel on a high-image-quality image (d) corresponding to the pixel A of interest as a target pixel R, and specifies a pixel having a pixel value closest to that of the target pixel among pixels in the adjacent region as an approximate pixel; and learning mans 13 which has a neural network constitution having an input layer, a plurality of intermediate layers, and an output layer, wherein the input layer comprises means for capturing respective pixels included in the peripheral region, the output layer comprises neurons, the number of which corresponds to the respective pixels included in the adjacent region, and a coefficient between neurons between the layers is changed such that a value of a neuron corresponding to the approximate pixel of the output layer is changed.SELECTED DRAWING: Figure 2
