Patent ID: 8094339

Claim:
A digital camera capable of communicating with a printer, comprising: an image sensor; and a printing system, the printing system comprising: an image receiving module capable of receiving a first image; a selection module capable of allowing selection of a desired print size for the first image; an availability module capable of determining available paper sizes of a printer connected to the digital camera; a comparison module capable of determining whether the printer supports the desired print size input to the selection module; a size module capable of selecting a paper size, from the available paper sizes, bigger than the desired print size if the printer doesn't support the desired print size; an image forming module for resizing the first image to form a second image including the first image therein if the printer doesn't support the desired print size, wherein the ratio of the size of the second image to the size of the first image therein is equal to the ratio of the paper size selected by the size module to the desired print size; and an image output module capable of receiving the second image, and outputting the received image to the printer; wherein the second image satisfies the following conditions: (1) a 1 /a 2 =A 1 /A 2 ; and (2) b 1 /b 2 =B 1 /B 2 , wherein a 1 is the length of second image, b 1 is the width of the second image, a 2 is the length of the first image including in the second image, the b 2 is the width of the first image including in the second image, A 1 is the length of the selected paper size, B 1 is the width of the selected paper size, A 2 is the length of the desired print size, and B 2 is the width of the desired print size.
