An image recording apparatus includes a light source, a switching drive circuit configured to control an electric current for causing the light source to emit a light beam, a moving part configured to move one of a recording target on which an image is to be recorded by the light beam and a light emitting position at which the light beam is emitted relative to another one of the recording target and the light emitting position, and a controller configured to control a light emission timing of the light source and a relative moving speed of the moving part based on image information. The drive circuit includes a switching circuit configured to turn on and off a switching element. The controller is configured to change a switching frequency of the switching element according to at least one of the light emission timing and the relative moving speed.

A method is provided of generating a pattern image used to form a pattern on a surface of a fabric using laser irradiation. A plurality of parameters associated with laser irradiation units are input into a user interface. The parameters include an area parameter, a laser irradiation unit density parameter, optionally a discontinuity parameter, and a dye removal parameter. A plurality of laser irradiation units arranged in a pattern area of a user interface based on computer processing of the inputted plurality of parameters is received for viewing at the user interface. The laser irradiation units collectively establish the pattern image for viewing by the user.
