PROBLEM TO BE SOLVED: To change the thickness of a protection layer by calculating the energy of recording the protection layer from the brightness component extracted from the image data of an N component and recording the protection layer according to the value. SOLUTION: A brightness component calculating device 7 receives Y, M, C data from a recording color data generating device 3 by one element for each time so a to convert the same to a brightness component. A protection layer recording gradation converting device 9 receives the brightness component of the pixel from the brightness component calculating device 7 so as to output the energy for recording the protection layer according to the received value. In recording the protection layer, a head data generating means 4 receives the output from the protection layer recording gradation converting device 9 and convert the same into a signal form so that a thermal head 5 can record this on a recording paper for recording (transferring) the protection layer on the recording paper. Therefore, the protection layer can be recorded according to the brightness of the image to be recorded, and thus the thickness of the protection layer can be changed according to the brightness component of the inputted image signal. |
