Abstract
An image recording apparatus with a variable magnification capability includes: a recording unit for recording an image by scanning a photosensitive material with a laser beam or the like; a circuit for generating an image recording signal for modulating the laser beam based on an image signal; an inputting unit for setting a desired magnification; and an adjusting circuit for adjusting the image recording signal based on the desired magnification. The adjusting circuit includes a circuit for setting the size of a standard image dot, and for changing the size, along the scanning direction of the beam, of a portion of the dots to obtain a desired degree of magnification/reduction of the image. The size of the standard dot is defined by a reference signal of a predetermined frequency. The size of the modified dots is defined by changing the frequency of the reference signal for the modified dots. The final image is comprised of a large number of the standard dots intermixed with a smaller number of the modified dots.
