Drawing method, heat-sensitive recording medium, and drawing device

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.
