Abstract

An endoscopic image display apparatus reads taken image data in which a taken image outputted from an endoscope is recorded, and reproduces and displays the taken image. The taken image data includes intensity information about a plurality of fundamental color components. The endoscopic image display apparatus includes an intensity changing unit which selectively reduces intensity of a specific color component in the taken image data by using the intensity information.

Claims

1. An endoscopic image display apparatus which reads taken image data in which a taken image outputted from an endoscope is recorded, and which reproduces and displays the taken image, the taken image data including intensity information about a plurality of fundamental color components, the endoscopic image display apparatus comprising:

an intensity changing unit that selectively reduces intensity of a specific color component in the taken image data by using the intensity information.

2. The endoscopic image display apparatus according to claim 1, wherein:

the specific color component is a blue color component.

3. The endoscopic image display apparatus according to claim 2, wherein:

intensity of the blue color component includes intensity of a light component of a wavelength band of from 400 nm to 420 nm.

4. The endoscopic image display apparatus according to claim 1, wherein:

the intensity changing unit includes an input portion which arbitrarily sets an intended value of reduction in the intensity of the specific color component.

5. The endoscopic image display apparatus according to claim 1, wherein:

the intensity changing unit uses intensity of at least one of the fundamental color components other than the specific color component, as the intended value of reduction in the intensity of the specific color component.

6. The endoscopic image display apparatus according to claim 1, wherein:

the taken image data is arranged to include the intensity information about the plurality of fundamental color components and information about image-taking conditions for the taken image data; and

the intensity changing unit includes;

a correction value storage portion which stores a correction value for correcting an intended value of reduction in the intensity of the specific color component in accordance with the image-taking conditions; and

an intensity changing portion which (i) acquires, from the correction value storage portion, the correction value corresponding to the information about the image-taking conditions read from the taken image data, (ii) corrects the intended value of reduction in the intensity with the acquired correction value, and (iii) changes the intensity of the specific color component.

7. The endoscopic image display apparatus according to claim 6, wherein:

the information about the image-taking conditions is information about a to-be-observed region of a to-be-inspected body in the taken image data.

8. The endoscopic image display apparatus according to claim 6, wherein:

the information about the image-taking conditions is information about a white balance adjustment value for adjusting white balance of the taken image outputted by the endoscope.

9. The endoscopic image display apparatus according to claim 6, wherein:

the information about the image-taking conditions is lighting time information which expresses total lighting time of a light source provided in the endoscope.

10. The endoscopic image display apparatus according to claim 1, wherein:

the taken image data is data of an image taken with illumination light whose spectroscopic profile includes laser light and light emitted from a fluorescent substance excited by the laser light.
