Abstract
An image recording apparatus which applies energy of distributed level to record, on a pixel by pixel basis, image fragments whose density or saturation (tone) corresponds to the necessary energy levels. Image fragments corresponding to an amount of heat of a comparatively high level are contained, on a pixel basis, in image fragments corresponding to an amount of heat of a comparatively low level, whereby record data of the image fragments corresponding to the amount of heat of the comparatively low level are provided. When image fragments corresponding to any of the levels are to be recorded, an amount of heat corresponding to a difference between that particular level and the lowest level is generated.
Claims4
An apparatus for recording multi-colored composite images on an energy sensitive recording medium, wherein said image is defined by a pixel by pixel basis and wherein the multi-color image requires one energy level to produce one color and a higher energy level to produce a second color wherein said apparatus comprises:
- a means for holding and advancing said recording medium;
- record data combining means for combining a plurality of kinds of image data to produce an image which is a composite image, in which some image fragments are produced in which the amount of energy necessary to produce said image fragments is an amount of energy of the low level for recording one color and which is lower than said high level necessary for recording said second color;
- a recording head for applying energy to said recording medium;
- energy applying means for applying to the record head, when said image fragment is to be recorded at said lower energy level, an amount of energy corresponding to said lower level and for applying to the record head, when said image fragment is to be recorded at the higher level needed to record a second color the difference between said low level of energy necessary to record said first color and said higher level.
