Title: IMAGE PROCESSING METHOD, IMAGE PROCESSING DEVICE, AND RECORDING MEDIUM FOR STORING IMAGE PROCESSING PROGRAM
Abstract:
 The present invention provides an image processing method, an image processing device, and an image processing program which require low computing costs and with which it is possible to minimize noise enhancement and halo generation caused by HDR. An image processing device according to one embodiment of the present invention has: a multi-resolution image generation means for generating a multi-resolution image; a correction amount calculation means for calculating a brightness correction amount on the basis of a lowest-resolution image of the multi-resolution image, a differential image between adjacent resolutions of the multi-resolution image, and edge information calculated at each resolution of the multi-resolution image; and a noise suppression means for calculating, on the basis of the lowest-resolution image, the differential image between adjacent resolutions, the edge information, and the brightness correction amount, an image after brightness correction in which a noise component is suppressed.
