Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To allow a processor to enhance a toner save function by forcibly assigning white level data to image data, whose resolution is converted into higher resolution than that of received image data. SOLUTION: A facsimile equipment stores once-received coded data to an image memory and decoded sequentially by a codec 8 and processed by an image-processing section 9 and printed out by a printer 10. The printer 10 is a laser printer or the like and has high resolution and the image-processing section 9 converts the resolution of the data in matching with that of the printer. When the resolution of the data is converted into a high resolution, it means that one-dot of data is converted into pluralities of dots, and the amount of consumption of toner and data is increased.  When the original image is not an image with high image quality, each dot of the data is ORed with each dot of a prescribed white level data pattern or the data are forcibly converted into white level data at a prescribed interval, so as to decrease the number of increased black level data to enhance a toner saving function effectively.
