Abstract (en)
[origin: WO9418800A1] The measurement of gray scale or color composition integrated densities of irregularly shaped areas of a subject specimen (52) is accomplished by using a video camera (54) to derive an analog video image signal representative of the optical intensity of light associated with the specimen. A modified low cost high speed video digitizer (58) converts the video image signal into a digital format which an interactive computer program (64) converts into digital optical density values that are used to determine the net integrated density of each irregularly shaped area within the specimen.
