Patent ID: 8358325

Claim:
An image processing method comprising: recording an image by irradiating a recording medium with laser beams which are arrayed in parallel at predetermined intervals to heat the recording medium, so that the image is composed of a plurality of lines written with the laser beams on the recording medium, wherein in the image recording, the plurality of lines written with the laser beams include a line written first and an overwritten line, a part of which is overlapped with the line written first; and the irradiation energy for the overwritten line is smaller than the irradiation energy for the line written first, and wherein a ratio X of an overlapped width of the overwritten line relative to a line width of the line written first, and a ratio Y of the irradiation energy for the line written first relative to the irradiation energy applied to the overwritten line satisfy the following Expression (1): 0.6≦−0.8 X+Y≦ 1.0 Expression (1).
