A processing method based on resist pattern formation, includes the steps of forming an electrostatic latent image on a photosensitive rotating drum, forming a toner image on the drum by developing the electrostatic latent image with a hot-melt toner, transferring the toner image on the drum onto a processing target member made of a material that is dissolved by an etchant, in accordance with hot-melt transfer, and processing the processing target member based on the toner image thereon as a resist pattern. The processing step has an etching step of causing the etchant to act on a surface of the processing target member on which the resist pattern has been transferred, thereby selectively etching the surface of the processing target member.

Video ID photo printing apparatus corrects the complexion of a person serving as an object into a desired color without any influences caused by controlling an illumination light source and the various control section of a video image pickup apparatus, printer characteristics, and the like. In order to extract the complexion data of the person serving as an object photographed by a color TV camera, a skin-color portion in a face image is detected by a detection point setting unit. A comparator compares the detected data value with a data value of a desired standard skin color formed in advance and stored in a standard color memory. The skin color of the picked up face image is converted into a desired skin color by a look-up table in accordance with a comparison result, and the data of the desired skin color is written in a frame memory. Thereafter, the face image which is subjected to color conversion is printed by a full-color printer.
