Image processing unit whose ability to process endoscopic image signal can be expanded, and endoscopic imaging system
First Claim
1. An endoscopic imaging system, comprising:
- an imaging apparatus having an imaging device for producing a motion picture signal representing an object image formed by an endoscope;
a main substrate having a signal processing means, which processes the motion picture video signal, which represents the object image and produced by said imaging device, and produces a digital motion picture signal, mounted thereon; and
an expansion substrate connected to said main substrate so that it can be disconnected freely, and having a processing circuit, which includes a digital motion picture compression circuit for compressing a digital motion picture signal produced by said signal processing means, and a compression signal output circuit for outputting a compression signal produced by said digital motion picture compression circuit, mounted thereon.

Abstract
When an endoscopic imaging system is employed in, for example, the department of otorhinology, a color processing expansion substrate, a still image production expansion substrate, and a still image compression/recording substrate are stacked on an expansion connector formed on a main substrate and are thus connected to the main substrate. A data bus and an address bus extending from a control unit mounted on the main substrate are linked to the expansion substrates. A sync signal generator outputs various kinds of sync signals including a clock signal CLK, a horizontal sync signal HD, a vertical sync signal VD, a field identification signal FLD, and a composite sync signal CSYNC to the expansion substrates.
