Image recording method and apparatus

摘要

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.
