Abstract
Image data transmitted through a line is recorded by conducting main scan by moving a recording head having a plurality of recording elements arranged in a sub-scan direction relative to a record medium in a main scan direction. A resolution in the main scan direction may be set by a user to a desired value through a switch, and the image data is thinned at a predetermined rate in accordance with the selected resolution and the speed to move the record head is increased.
Claims13
An image communication apparatus capable of recording an image on a record medium at a first resolution in accordance with image data transmitted through a line by record-scanning by using record means having a plurality of recording elements arranged at a predetermined recording density, comprising:
- selection means for selecting a resolution of the image to be recorded by said record means;
- supply means for dropping the image data at a predetermined rate when a second resolution lower than said first resolution of the image to be recorded by said record means is selected and supplying the dropped image data to said record means;
- and
- scan means for conducting the record-scanning of said record means at a high speed in accordance with said second resolution, wherein said scan means conducts the record-scanning at the second resolution at a speed of (the first resolution)/(the second resolution) times of the speed in the first resolution.
