Title:
IMAGE PROCESSING DEVICE AND MULTI-FRAME PROCESSING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/131655
Kind Code:
A1
Abstract:
Disclosed is an image processing device according to an embodiment, the image processing device comprising memory which stores one or more instructions, and a processor which executes the one or more instructions stored in the memory, wherein the processor: identifies, in a previous frame, a prediction sample corresponding to the current sample in the present frame; generates a prediction frame for the current frame by changing a sample value of a collocated sample of the previous frame according to a sample value of the prediction sample; derives a weight by comparing the sample value of the current sample with the sample value of the prediction sample; applies the weight to the collocated sample of the prediction frame in order to acquire a weighted prediction frame; and acquires the current output frame by processing the weighted prediction frame and the current frame through a neural network including a convolutional layer, wherein the collocated sample of the previous frame and the collocated sample of the prediction frame are collocated samples for the current sample.
