Problems solved by technology

Therefore, when a user (doctor) who uses an ordinary endoscope wishes to observe a fluorescence image, he / she must separately purchase expensive fluorescence endoscope equipment
However, in many cases, the observation of fluorescent images is only performed to supplement the observation of ordinary images, and the frequency of observing fluorescent images is much less than that of ordinary images

Embodiment Construction

[0153] A first embodiment of the present invention will be described in detail below with reference to the accompanying drawings. figure 1 is a schematic diagram showing the configuration of a fluorescence endoscope apparatus to which the first embodiment of the present invention is applied.

[0154]The fluorescence endoscope apparatus 100 according to the present embodiment operates in the normal image mode and in the fluorescence image mode. In the normal image mode, the region 10 to be observed is irradiated with the illumination light L1 to acquire a color normal image, and the acquired image is displayed in the form of animation (video image, dynamic image, etc.). In the fluorescent image mode, the region 10 to be observed is irradiated with illumination light L1 and excitation light L2 to acquire a color image, and a pseudo-color normal image is acquired from the acquired color image through operation processing (to be described later). In addition, pseudo-color normal...

Abstract

A fluorescent image obtainment apparatus includes a light illumination means (130, 150) that illuminates a region to be observed with illumination-light and excitation-light at the same time, and an imaging means (110) that captures an image composed of light reflected from the region illuminated with the illumination-light and an image composed of fluorescence output from the region illuminated with the excitation-light. Further, the apparatus includes an image processing means (170) that produces an ordinary image based on the image of the reflection light and a fluorescent image based on the image of fluorescence, and a light amount control means (186) that controls the light amount of the illumination-light so that a representative luminance value of the ordinary image becomes a predetermined luminance value and the light amount of the excitation-light so that the ratio of the light amount of the excitation-light to that of the illumination-light becomes a predetermined ratio.

Description

technical field [0001] The invention relates to a fluorescence image acquisition method, a fluorescence image acquisition device, a fluorescence endoscope device and an excitation light device. Specifically, the present invention relates to a fluorescence image acquisition method, a fluorescence image acquisition apparatus, and a fluorescence endoscope apparatus that generate a fluorescence image by acquiring an image containing fluorescence emitted from an observed region irradiated with excitation light. Furthermore, the present invention relates to an excitation light device that emits excitation light to generate a fluorescent image. Background technique [0002] Conventionally, endoscopic apparatuses for observing tissues in a patient's body cavity (in vivo) are widely known. Also, electronic endoscopes are widely used, which acquire general images by imaging the area in the body cavity while irradiating the area with white light, and display the acquired images on a m...
