Abstract
The present invention allows output of image data without change when input image data and image data to be outputted have different resolutions and also allows reduction in a processing time and improvement in operating efficiency by providing an image recording apparatus. Some of lenses which form a telecentric lens system (optical system) are provided such that positions thereof in a direction along an optical axis can be varied by drive of a pulse motor 10. Due to the movement of these lenses, an imaging spot diameter on a photosensitive material is varied. The spot diameter is varied based on a resolution of the input image data. When the resolution of the input image data is lower than a previously set resolution, with the volume of the image data being left unchanged and the imaging spot diameter being increased, the previously set resolution is varied and recorded.
