Abstract

It is an object of the present invention to provide a video processing apparatus which makes it possible to print a picture having an arbitrary size without forging an original picture. A video processing apparatus according to the present invention includes a print size selecting means 51 for selecting a print size of a printer 3 by selecting a size of a picture frame, a CPU 43 for determining the number of pixels of a video data corresponding to the selected print size, and a memory controller 33 for processing the video data in accordance with the number of pixels so that pixels of a video data output from a camera 1 should be in one-to-one correspondence with pixels of a video data to be printed by the printer 3. It is not necessary to subject the original picture to video processings such as a decimating processing, an interpolation processing or the like. Therefore, it is possible to obtain a printed picture having an arbitrary size without forging an original data as required when an attesting photograph is taken.

Dependent claims

A video processing apparatus comprising:

an imaging means for imaging an object through an optical system to obtain an electric signal through conversion and outputting a signal as a video data;
a display means for displaying a picture of said video data in a predetermined picture frame;
a printing means for printing the picture in said picture frame of said video data;
a print size selecting means for selecting a print size of the picture to be printed by said printing means;
a pixel-number determining means for determining the number of pixels of said video data corresponding to the print size selected by said print size selecting means;
and
a video data processing means for processing said video data based on the number of pixels determined by said pixel-number determining means so that the pixels of said video data output from said imaging means should be in one-to-one correspondence with the pixels of said video data printed by said printing means and so that the number of pixels of said video data output from said imaging means is the same as the number of pixels of said video data printed by said printing means,
wherein said pixel-number determining means determines the number of vertical-direction pixels based on a transmission system of said video data.
