Abstract:
1. An image processing method comprising: delivering laser light to a thermoreversible recording medium so as to heat the thermoreversible recording medium and record an image thereon, the thermoreversible recording medium reversibly changing a transparency or tone thereof depending on a temperature thereof; and heating the thermoreversible recording medium so as to erase the image recorded on the thermoreversible recording medium, wherein the delivering is carried out using an image processing device which comprises: a laser light emitting unit; a light scanning unit disposed on a plane onto which laser light emitted from the laser light emitting unit is delivered; a light intensity distribution adjusting unit configured to change a light intensity distribution of the laser light; and a fθ lens configured to condense the laser light, and wherein energy of the laser light which passes through a peripheric portion of the fθ lens and travels onto the thermoreversible recording medium is lower than energy of the laser light which passes through a center portion of the fθ lens and travels onto the thermoreversible recording medium.
