专利汇可以提供Color separation for discrimination in pattern recognition systems专利检索，专利查询，专利分析的服务。并且A color separation system is provided for use in combination with a pattern recognition system which is particularly useful in blood cell analysis. The color separation means include filtering means for transmitting from a field having a plurality of patterns light in a plurality of spectral bands. Photomultiplier means are responsive to the filtering means for providing a pluarlity of electrical signals each of which varies in accordance with the light intensity in one of the spectral bands. The signals are utilized by the pattern recognition system and facilitate discrimination of predetermined patterns in the field.，下面是Color separation for discrimination in pattern recognition systems专利的具体信息内容。

权利要求

1. A pattern recognition system for use in distinguishing white blood cells in a whole blood smear comprising means for scanning a field in said whole blood smear, said means for scanning generating light in accordance with the color of said images in said field, quantization means for generating binary signals representative of the positions of said field scanned, storage means responsive to said quantization means for serially shifting and storing said binary quantization, and pattern recognition means connected to said storage means for analyzing the binary quantization of said field for distinguishing the pattern scanned in said field wherein the improvement comprises color separation means for receiving said generated light from said means for scanning, said color separation means including filtering means for transmitting from said light in said field light only in a predetermined plurality of portions of the light spectrum, means responsive to said filtering means for providing a plurality of electrical signals, each of which varies in accordance with the light intensity in one of said portions of the light spectrum, said means responsive to said filtering means including means for removing from said plurality of electrical signals essentially all of said signals representative of a red cell, said means responsive for generating a resulting signal which is connected to said quantization means, said quantization means receiving said resulting electrical signal and for providing the binary quantization thereof for each position of the field scanned, said binary quantization of said field including white cell information and an insubstantial portion of red cell information so that red cell information is not analyzed during analysis of said binary quantization.

2. THe pattern recognition system of claim 1 wherein said means for removing information relative to red blood cells includes means for combining a pair of said electrical signals, said combining means comprising a subtractor, said combining means receiving signals, each of which includes approximately the same amount of red cell information so that subtraction of one of the signals from the other causes removal of the red cell information.

3. The pattern recognition system of claim 1 wherein said scanning means comprises a flying spot scanner and a microscopic lens system for focusing a beam of light from said scanner onto said field in said blood smear.

4. The pattern recognition system of claim 2 wherein said plurality of portions of the light spectrum comprise the green, blue and red spectral bands and said combining means receives signals representative of the blue and green spectral bands.

5. The pattern recognition system of claim 1 wherein said system includes a plurality of means for combining each of which combines a different combination of said electrical signals, said quantizing means including a plurality of quantizers each responsive to one of said combined electrical signals, said plurality of combined signal quantizers providing additional information to said pattern recognition system for discrimination of predetermined patterns in said field.

6. The pattern recognition system of claim 1 wherein said color separation means includes a plurality of dichroic mirrors which are used to separate the components of light from said field into the red spectral band, the green spectral band and the blue spectral band.
