Image processing device

Abstract

Abstract PURPOSE:To separate the particles overlapping or touching with each other in a short time by setting plural projection axes to a picture of detected particles and separating the particles based on the projected picture of each projection axis. CONSTITUTION:The image of a sample 1 which is converted into electric signals by a photoelectric transducer 2 is supplied to a particle detector 4 as well as to a picture memory 5 via an A/D converter 3. The memory 5 freezes the data on particles having areas larger than a fixed value within the memory 5 and at the same time delivers the stand-by signal to a CPU7. A picture arithmetic means 6 performs the binary coding, elimination of noises, calculation of length of a contour line, calculation of particle areas, etc. Based on these arithmetic results, it is decided whether the particles detected by the detector 4 are individual to each other or overlapping or touching with each other.
