Video overhead display system
First Claim
Patent Images
1. A video overhead display system for displaying an image of an object, comprising:
- image enlarging means for magnifying an optical image of the object;
image pick-up means for receiving the magnified optical image of the object and converting the magnified optical image into an electronic image signal;
image output means for receiving the electronic image signal and converting the electronic image signal into a displayed image; and
image reversing means which selectively reverses the image of the object, wherein the image reversing means further includes,an A/D converter which receives an electronic image signal output from the image pick-up means and converts the electronic image signal into a digital image signal,an image reverser, which receives the digital image signal from the A/D converter, selectively reverses the digital image signal, and outputs the selectively reversed digital image signal,a digital signal processor which processes the digital image signal received from the image reverser, and outputs a luminance signal, a chrominance signal, and a composite synchronizing signal, andan image signal processor which combines the luminance, chrominance, and composite synchronizing signals, and outputs the combined signals as a composite image signal.

Abstract
A video overhead display system for displaying an image of an object includes an image enlarging unit for magnifying an optical image of the object. An image pick-up unit receives the magnified optical image of the object and converts the magnified optical image into an electronic image signal. An image output unit receives the electronic image signal and converts the electronic image signal into a displayed image.

4. A video overhead display system for displaying an image of an object, comprising:
-
a body having a control panel; an image enlarger for magnifying an optical image of the object; an image pick-up unit connected to the body, and which picks up the magnified optical image of the object, and wherein the image enlarger is separably mounted to the image pick-up unit; an image reversing device which selectively reverses the image of the object, wherein the image reversing device further includes an A/D converter which receives an electronic image signal output from the image pick-up unit and converts the electronic image signal into a digital image signal, an image reverser, which receives the digital image signal from the A/D converter, selectively reverses the digital image signal, and outputs the selectively reversed digital image signal, a digital signal processor which processes the digital image signal received from the image reverser, and outputs a luminance signal, a chrominance signal, and a composite synchronizing signal, and an image signal processor which combines the luminance, chrominance, and composite synchronizing signals, and outputs the combined signals as a composite image signal. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
