Abstract: A video printer for printing a plurality of kinds of images having different image formats, consisting of an image memory for storing image data of one image portion of an input image signal, an image data processing unit for converting image data from the image memory into image printing data, an image printing unit for executing an image printing based on image printing data from the image data processing unit, an input image format decision unit for deciding an image format of an image signal inputted to the image memory, an image format decision unit for deciding an image printing format determined by either an image printing sheet or an ink sheet set to the image printer, an operating portion for inputting an instruction of an operator, and a system controller for controlling the image memory or the image data processing unit so that the image signal inputted to the image memory is printed to match the image printing format, based on an input signal decision signal from the input image format decision un

Abstract: A video memory control apparatus has a frame memory in a video printer or the like constituted by two field memories. The two field memories are arranged so as to be switched in response to a signal obtained by frequency-dividing a vertical synchronizing signal into halves. At this time, not only the respective outputs of the two field memories are switched but also the supply of clock pulses for writing/reading is switched in response to the frequency-divided signal.

Abstract: A thermal-transfer recording method and an apparatus used for this method in which ink on an ink tape is heat-transferred in the form of a mirror image of a desired image to an intermediate recording sheet having a base film and an ink absorbing adhesive layer formed on the base film, and in which the intermediate recording sheet to which the mirror image has been heat-transferred is bonded to a desired recording medium at the surface of the ink absorbing adhesive layer.
