Patent Number: 8,798,379

Title: Image processing method, encoding device, decoding device, and image processing apparatus

Abstract: There is provided an image processing method includes: separating an image taken at a predetermined frame rate into a first frame and at least one second frame other than the first frame at intervals of 1/n, where n is an integer of 2 or larger; calculating a low-frequency-component difference between the separated at least one second frame and first frame; performing signal processing designated by a user on the first frame; decompressing, using a low-frequency component in the first frame being subjected to the signal processing and the low-frequency-component difference, a low-frequency component in the at least one second frame being approximately subjected to the signal processing; and decompressing, using the decompressed low-frequency component in the at least one second frame and a high-frequency component therein, the at least one second frame being approximately subjected to the signal processing.
