[57] ABSTRACT
The measurement of integrated densities of irregularly shaped areas of a subject specimen is accomplished by using a video camera 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 converts the video image signal into a digital format which an interactive computer program converts into digital optical density values that are used to determine the net integrated density of each irregularly shaped area within the specimen.
