Abstract

Apparatus for printing images from a display included within an image capture device including a display for producing an image captured by the image capture device; a printer which includes photosensitive media which is adapted to be illuminated by an light image from the display; and a structure for controlling the display so as to produce a color image which is color balanced. The apparatus presents a photosensitive medium to be illuminated by the color balanced image.

Claims

1. Apparatus for printing images from a display included within an image capture device, comprising:

a) a display for producing an image captured by the image capture device;

b) a printer which includes photosensitive media which is adapted to be illuminated by an light image from the display;

c) means for controlling the display so as to produce a color image which is color balanced; and

d) means for presenting a photosensitive medium to be illuminated by the color balanced image.

2. Apparatus for printing images from a liquid crystal display included within an image capture device, comprising:

a) a liquid crystal display for producing an image captured by the image capture device;

b) a source of light for illuminating the liquid crystal display;

c) a printer which includes photosensitive media which is adapted to be illuminated by an light image from light passing through the liquid crystal display; and

d) means for controlling a predetermined number of exposures of the photosensitive media by light from the liquid crystal display so as to produce a color image which is color balanced.

3. The apparatus of claim 2 wherein there are a plurality of exposure intervals for different color channels.

4. The apparatus of claim 3 wherein there are three exposures, the first permitting broad band light from the liquid crystal display to expose the photosensitive medium, the second to restrict green light from the display for exposing the photosensitive medium, and the third for restricting green and blue light for exposing the photosensitive medium.
