Abstract

To provide an imaging device capable of forming two images on different areas of a single imaging element without greatly changing the focus position while suppressing the increase in size of the entire imaging device, and capable of expanding the depth of focus in a continuous range and camera system. It has: an objective optical system (1), which is used to image a light beam from an object; an imaging element (3), which is arranged near the imaging position of the objective optical system; a splitting element (4), which is arranged between the objective optical system and the Between the imaging elements, it is used to split the light beam from the objective optical system into two light beams, the reflected light beam and the transmitted light beam; the first reflective part (6), which is used to reflect the light beam reflected by the split element to turn it back and a second reflective component (7), which is used to reflect the light that has passed through the split element, wherein the light beam reflected by the first reflective component is imaged on the first region (3a) in the imaging element via the split element , forming an image of the light beam reflected by the second reflective member on a second area (3b) different from the first area in the imaging element.

Description

technical field [0001] The present invention relates to an imaging device and an imaging device system having a deep depth of focus suitable for, for example, endoscopic observation. Background technique [0002] Conventionally, there is an imaging device that expands the depth of focus by selecting and synthesizing an image with good contrast among two images having different focus positions. [0003] As one of conventional imaging devices, there is an imaging device such as the imaging devices described in Patent Document 1 and Patent Document 2, which divide one light beam into two by a half prism and capture images of the divided light beams. The optical paths of the two imaging elements are staggered so that the focus positions of the two images imaged on each imaging element are different. [0004] Figure 11 It is a figure which shows the schematic structure of the imaging device described in patent document 1. [0005] The imaging device described in Patent Documen...
