Patent attributes
Using a picture image printing system, both types of pictures recorded by a camera using a film and a digital camera are effectively printed. The printing system comprises a film scanner for inputting a picture recorded on a film, and a card reader for inputting a picture recorded by a digital camera. By switching between the scanner and card reader upon necessity, digital image data is obtained. An image processing apparatus performs pixel number conversion on the digital image data by keeping an aspect ratio of the image constant, so that the picture image data is printed in a width almost the same as a width of rolled paper. The digital image data whose pixel number has been converted are subsequently printed on the rolled paper by a printer.
