Abstract:
1. A method for image processing, comprising: at least any one of image forming step and image erasing step, wherein an image is formed on a thermoreversible recording medium in which any one of transparency and color tone is changed reversibly depending on temperatures attained by the medium by heating due to laser beam irradiation to the thermoreversible recording medium in the image forming step, an image formed on the thermoreversible recording medium is erased by heating due to laser beam irradiation to the thermoreversible recording medium in the image erasing step, and a light irradiation intensity of the center is 1.05 times or less than 1.05 times the light irradiation intensity of the periphery in the light intensity distribution of cross-section in a direction approximately perpendicular to the traveling direction of the laser beam irradiated at least in any one of the image forming step and the image erasing step.
