Abstract
Abstract A digital control color illumination system is disclosed for use in a visual system of an industrial robot or the like. This system comprises: image memories to store the color data regarding illumination patterns of three primary colors of red, green, and blue; video signal producing circuits each for reading out the data from the image memory and converting it to the video signal indicative of the illumination pattern; video projectors each for projecting the light of the illumination pattern represented by the video signal onto an object to be illuminated; and a color TV camera to pick up the object image. The image data picked up is processed by a computer system to produce the data which is stored into the image memories. With this illumination system, the scanning of the illumination patterns, and the change, adjustment, storage, and the like of the illumination patterns can be executed by software in accordance with programs preliminarily stored in the program memory in the computer system.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
74 words
A digital control illumination system comprising: an image memory for storing data regarding a predetermined illumination pattern; video signal producing means for reading out the data from said image memory and converting said data to a video signal indicative of the illumination pattern; and light irradiating means for projecting the light of the illumination pattern represented by said video signal onto an object, said irradiating means including a lens through which said light passes.
Claim 2
Dependent Claim
74 words
A digital control illumination system comprising: an image memory for storing data regarding a predetermined illumination pattern; video signal producing means for reading out the data from said image memory and converting said data to a video signal indicative of the illumination pattern; and light irradiating means for projecting the light of the illumination pattern represented by said video signal onto an object, said irradiating means including a lens through which said light passes.
Claim 3
Dependent Claim
46 words
An illumination system according to claim 1, further comprising: image pickup means for picking up the image of the object; and image processing means for executing a predetermined process to the image data picked up and producing the data which is stored into said image memory.
Claim 4
Dependent Claim
31 words
An illumination system according to claim 1, further comprising means for moving a predetermined data of said image memory in the image memory to cause the illumination light to be scanned.
Claim 5
Dependent Claim
20 words
An illumination system according to claim 1, further comprising image pickup means for picking up the image of the object.
Claim 6
Dependent Claim
32 words
An illumination system according to claim 4 further comprising synchronizing control means for allowing the operations of said light irradiating means and said image pickup means to be synchronized with each other.
Claim 7
Dependent Claim
56 words
An illumination system according to claim 4, further comprising means for deflecting at least one of the light projected from said light irradiating means and light received by said image pickup means in order to make the optical axes of said light irradiating means and said image pickup means coincident at a location near the object.
Claim 8
Dependent Claim
70 words
An illumination system according to claim 4, further comprising: filtering means having a plurality of filters for allowing lights of a plurality of different colors to pass, said filters moving in front of said light irradiating means; and means for controlling said image pickup means so as to pick up the image of the object synchronously with the movement to said filters and synthesizing a plurality of image data obtained.
Claim 9
Dependent Claim
98 words
A digital control color illumination system comprising: an image memory for storing data regarding illumination patterns of color components of a plurality of different colors; video signal producing means for producing a video signal indicative of the illumination pattern of each color component on the basis of the data read out from said image memory and then outputting said video signal; and light irradiating means for projecting the light of said illumination pattern for each color component which is represented by said video signal onto an object, said irradiating means including a lens through which said light passes.
Claim 10
Dependent Claim
98 words
A digital control color illumination system comprising: an image memory for storing data regarding illumination patterns of color components of a plurality of different colors; video signal producing means for producing a video signal indicative of the illumination pattern of each color component on the basis of the data read out from said image memory and then outputting said video signal; and light irradiating means for projecting the light of said illumination pattern for each color component which is represented by said video signal onto an object, said irradiating means including a lens through which said light passes.
Claim 11
Dependent Claim
21 words
A color illumination system according to claim 8, further comprising image pickup means for picking up the image of the object.
Claim 12
Dependent Claim
75 words
A color illumination system according to claim 8, further comprising: a plurality of light irradiating means for projecting a plurality of lights corresponding to the illumination patterns of the colors for a plurality of different color components; and means for deflecting at least one of said plurality of projection lights in order to make the optical axes of the projected lights from said plurality of light irradiating means coincident at a location near the object.
