Abstract

A drawing method according to an embodiment of the present disclosure to be performed on a heat-sensitive recording medium including a recording layer, the recording layer containing a leuco dye and a photothermal conversion agent that absorbs infrared wavelength light, includes: performing drawing in a plurality of first regions, the plurality of first regions each extending in one direction and having gaps therebetween; and thereafter detecting recorded states of the plurality of first regions, calculating differences from the input image information, and performing drawing in a plurality of second regions at recording intensities determined on a basis of the differences, the plurality of second regions each extending in the one direction and being provided at the gaps between the plurality of first regions.

First claim

The invention claimed is:

1. A drawing method to be performed on a heat-sensitive recording medium including a recording layer, the recording layer containing a leuco dye and a photothermal conversion agent that absorbs infrared wavelength light, the drawing method comprising:
performing drawing in a plurality of first regions, the plurality of first regions each extending in one direction and having gaps therebetween; and
thereafter detecting recorded states of the plurality of first regions, calculating differences from the input image information, and performing drawing in a plurality of second regions at recording intensities determined on a basis of the differences, the plurality of second regions each extending in the one direction and being provided at the gaps between the plurality of first regions.

2. The drawing method according to claim 1 , wherein the drawing in the plurality of first regions and the drawing in the plurality of second regions are each performed using a light beam.

3. The drawing method according to claim 2 , wherein the recording intensities are each adjusted by an output of the light beam.

4. The drawing method according to claim 1 , comprising:
performing drawing in a plurality of third regions at recording intensities determined on a basis of the differences, the plurality of third regions each extending in the one direction and each of the plurality of third regions being provided between the plurality of first regions and the plurality of second regions.

5. A drawing device comprising:
a light source section that emits a light beam;
a scanner section that performs drawing, on a recording layer containing a leuco dye and a photothermal conversion agent that absorbs infrared wavelength light to generate heat, by scanning the light beam emitted from the light source section in a plurality of first regions and a plurality of second regions, the plurality of first regions each extending in one direction and having gaps therebetween, the plurality of second regions each extending in the one direction and being provided at the gaps between the plurality of first regions;
a detector that detects a recorded state of the recording layer; and
a corrector that determines a recording intensity on a basis of a result obtained by the detector, wherein
the scanner section performs scanning in the plurality of first regions on a basis of input image information,
the detector detects recorded states of the plurality of first regions in which drawing has been performed by the scanner section, and outputs, as image information of the plurality of first regions, the recorded states of the plurality of first regions to the corrector,
the corrector calculates differences between the image information of the plurality of first regions inputted from the detector and the input image information, and determines, on a basis of the differences, recording intensities of drawing on the plurality of second regions, and
the scanner section performs scanning in the plurality of second regions using the recording intensities determined by the corrector.
