Problems solved by technology

[0008] In the past, many BNC terminals were used as connectors for RGB signals and YPbPr signals. In the previous method of switching the input channel to the monitor, the number of connected terminals increased, and the work of connecting and switching became cumbersome. Shortcomings
[0009] In addition, a lot of space is required for connection, and there is a problem that miniaturization is difficult

Embodiment 1

[0052] refer to Figure 1 to Figure 21 Example 1 of the present invention will be described.

[0053] figure 1 The shown endoscope system 1 includes: endoscopes (abbreviated as endoscopes) 2A and 2B, which are inserted into body cavities to perform endoscopic inspection, etc.; , B) provide illuminating light; video processor 4, it has the signal connector holder 10 that connects the signal connector of endoscope 2I freely, as the camera unit that is installed on the endoscope 2I carries out signal processing The signal processing device for an endoscope; and the monitor 5 receive video signals via a connector detachably connected to the video processor 4, thereby displaying an endoscopic image captured by the imaging unit.

[0054] In this embodiment, various CCD9Is are installed in the endoscope 2I, so that the video processor 4 detachably connected to the endoscope 2I can perform signal processing corresponding to various CCD9Is. That is, in figure 1 Although there is ...

Abstract

The signal processing device for an endoscope has first and second video signal generating circuits respectively corresponding to the first and second video signal generating circuits attached to the endoscope detachably connected to the endoscope connecting portion. In the case of the first imaging element and the second imaging element, the first video signal and the second video signal having different resolutions are generated. The first and second video signals can be selectively output to the outside from a common video signal output connector.

Description

technical field [0001] The present invention relates to a signal processing device for an endoscope that generates various video signals from imaging signals of a solid-state imaging element mounted on the endoscope. Background technique [0002] In recent years, endoscope systems that perform endoscopic inspection and endoscopic diagnosis by displaying endoscopic images captured by an imaging unit using a solid-state imaging device on a display unit have been widely used. [0003] For example, in the endoscope system disclosed in Japanese Patent Application Laid-Open No. 6-169886, an endoscope image and images from external devices such as VTRs, image printers, and image filing devices can be selected for monitoring and display. [0004] In this endoscope system, there are a plurality of terminals for inputting various video signals (specifically, RGB signals, S / Y separated video signals, and composite video signals) from the video processor to the monitor. Any video signa...
