Video photometric color system for processing color specific streams

A video photometric color sensing system for characterizing the color of a homogeneous substance by controlling the rate of color change of said homogeneous substance, comprising:

• (a) a process stream of said homogeneous substance;
• (b) a sample port for receiving a sample stream from said homogeneous process stream;
• (c) equipment means for increasing or decreasing the color hue of said homogeneous process stream;
• (d) camera means for quantifying a color video image of said homogeneous substance within said sample port and providing as outputs analog voltage signals representative of the amount of red, green and blue in said color video image;
• (e) peak detector circuit means for receiving said analog voltage signals representative of the amount of red, green and blue in said color video image and generating peak red, green and blue analog voltage signals and for using the individual voltage values of each red, green and blue component to derive the luminance value from software generated nonadditive matrix;
• (f) converter means for converting each of said peak red, green and blue analog voltage signals and said luminance value to corresponding digital levels;
• and
• (g) processor means for receiving said red, green, blue and luminance digital levels from said converter means and comparing said received red, green, blue and luminance digital levels to red, green, blue and luminance reference levels stored within said processor means to determine the actual concentration of said homogeneous substance within said sample port;
• said processor means providing an operating signal to said converter means which in turn is transmitted to said equipment means when said actual color of said homogeneous process stream does not match the preselected desired level of color of said homogeneous process stream.
