Title:
IMAGE PROCESSING DEVICE AND LEARNING METHOD
Document Type and Number:
Japanese Patent JP2022143211
Kind Code:
A
Abstract:
To make it possible to output a more suitable demosaic image.SOLUTION: An image processing device that performs image processing using a neural network (NN) includes: acquisition means for acquiring teacher image data; generation means for generating student image data obtained by mosaicking the teacher image data; weight acquisition means for acquiring a loss weight map indicating a weight of a loss value at each pixel position of the teacher image data; and learning means for performing learning of demosaic processing based on a difference between result image data obtained by inputting the student image data to the NN and the teacher image data, and the loss weight map. In the loss weight map, the weight of the loss value at a pixel position of a specific phase in the teacher image data is different from the weight of the loss value at a pixel position other than the specific phase.SELECTED DRAWING: Figure 4
