An image is recorded on an image recording material by energizing a thermal head having a plurality of heating elements with input image data. As the image recording material, there is employed a heat sensitive recording material comprising a support coated with a coating solution which makes an unheated area colored and a heated area transparent in a colorless or light colored manner. An image is recorded on the heat sensitive recording material with the thermal head by processing the image data through negative-positive reversal and applying the processed image data to the thermal head. The image data are processed through negative-positive reversal by converting the image data based on a function which has the input image data as a variable and a negative differential coefficient. |

DETAILED DESCRIPTION It is a general object of the present invention to provide a method of and an apparatus for thermally recording an image, characters, or the like on a heat sensitive recording material of the type described above with a thermal head, such that the same image is reproduced in an image area 4 (FIG.
1) whereas an image colored at a prescribed density is formed in a non image area 6, by applying an image signal reversed in negative-positive relationship to the thermal head, so that an image thermally recorded on the heat sensitive recording material can easily be visually recognized when it is observed on a light table such as an illuminating box.
Another object of the present invention is to provide a method of recording an image on an image recording material by energizing a thermal head having a plurality of heating elements with input image data, the method comprising the steps of employing, as the image recording material, a heat sensitive recording material comprising a support coated with a coating solution which makes an unheated area colored and a heated area transparent in a colorless or light colored manner, and recording an image on the heat sensitive recording material with the thermal head by processing the image data through negative-positive reversal and applying the processed image data to the thermal head.
Still another object of the present invention is to provide the method wherein the image data are processed through negative-positive reversal by converting the image data based on a function which has the input image data as a variable and a negative differential coefficient.
Yet another object of the present invention is to provide an apparatus for recording an image on a heat sensitive recording material comprising a support coated with a coating solution which makes an unheated area colored and a heated area transparent in a colorless or light colored manner, the apparatus comprising negative-positive reversal means for processing the input image data through negative-positive reversal, and a thermal head having a plurality of heating elements energizable by the processed image data for recording an image on the heat sensitive recording material held against the thermal head based on the processed image data
