Abstract
Abstract In a television system used in a training device to synthesize a television display, a color presentation is derived from black and white video signals. A black and white signal is selectively attenuated or amplified in three separate circuits connected to the respective color guns in a color television receiver. Running lights are provided to simulate the appearance of a ship at night. Means are provided to simulate a missile ship.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
In a television system using a monochrome television camera to generate video information and a color television monitor for displaying said video information, the improvement comprising: connecting means connecting said camera to said monitor for transmitting said video information from said camera to said monitor, said connecting means comprising three separate channels, each of said channels comprising a variable attenuator for selectively attenuating said video information in a respective channel and a video gate for selectively inhibiting said video information in said respective channel, the output of said camera being connected to each of said channels, the output of each of said channels being connected to a respective one of the red, green, and blue electron guns in the picture tube of said color television monitor, whereby said video signal may be displayed on said monitor in colors determined by the selected adjustments of said variable attenuators.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
138 words
The apparatus of claim 1, and including: a first model having a realistic appearance, a first monochrome camera, said first model being positioned in the field of view of said first camera, a second model having a dark non-reflective finish, a second monochrome camera, said second model being positioned in the field of view of said second camera, a plurality of simulated lights having a lighter appearance affixed to said second model, said first camera and said second camera each being connected to said monitor by respective connecting means such as described in claim 1, and video selection logic circuits for controlling said video gates to display an image of said first model on said monitor to simulate a daytime scene and to display an image of said simulated lights on said monitor to simulate a nighttime scene.
Claim 4
Dependent Claim
63 words
The apparatus of claim 2, and including: a missile model, a third monochrome camera, said missile model being positioned in the field of view of said third camera, said third camera being connected to said monitor by connecting means such as described in claim 1, said video selection circuits being connected to control said video gates to display said missile on said monitor.
