Abstract
The improved thermal image recording method for forming an image to be recorded corresponding to image data on a thermal recording material using a thermal head, includes the steps of dividing the image to be recorded on one screen into a specified number of regions each having a specified number of pixels and calculating for each of the regions a representative value of the image data within that region; calculating a predicted value of temperature for each of the regions from the representative value of the image data within that region and an initial value of temperature as detected with a specified number of thermistors; calculating a value of temperature correction for each of the regions from the predicted value of temperature for that region; interpolating the values of temperature correction for the regions to calculate a value of temperature correction for each of the pixels in the image to be recorded on one screen; and performing temperature compensation on the image data of each of the pixels. The improved thermal recording apparatus carries out the improved thermal recording method described above. These apparatus and method are capable of recording high quality images at high speed without uneven densities.
