[0117] 3.1. Endoscopic device

[0118] Figure 10 A second configuration example of the endoscope device is shown. The endoscope device includes a light source unit 100 , an imaging unit 200 , a control device 300 (processor unit), a display unit 400 , and an external I / F unit 500 . main pair with figure 1 The structural elements that are different from the first structural example described above will be described, and the description of the same structural elements will be appropriately omitted.

[0119] The light source unit 100 includes a white light source 101 and a condensing lens 104 that condenses light onto an incident end face of the optical fiber 201 . In the second configuration example, there is no rotary color filter.

[0120] In the imaging unit 200 , a primary color single-plate imaging element is used as the imaging element 209 in the second configuration example. The primary color single-plate imaging element is a so-called Bayer array imaging element, a...

Abstract

This image processing device for use with an endoscope contains an image acquisition unit (305) and a boundary-region correction unit (315). The image acquisition unit (305) acquires an image signal in which a front image corresponding to a front field of view and a side image corresponding to a side field of view form a single acquired image comprising a front region, namely the region of the acquired image corresponding to the front field of view, and a side region, namely the region of the acquired image corresponding to the side field of view. The boundary-region correction unit (315) makes the front-region image and / or the side-region image overlap a boundary region, said boundary region being the boundary between the front region and the side region.

Description

technical field [0001] The present invention relates to an image processing device for an endoscope, an endoscope device, an image processing method, and the like. Background technique [0002] Conventionally, in endoscopic diagnosis, there is a need to improve the detection accuracy of lesions in a body cavity, and an endoscopic body having a wide-angle optical system of 170 degrees has been developed. [0003] In the above-mentioned endoscopic body, for example, the inner side of the folds of organs with large folds such as the large intestine, etc., the area located on the side and behind the side sometimes does not enter the field of vision, so it is sometimes difficult to obtain information that exists in this area. Lesions in the region as images.
