Abstract
[Object] It is desirable to provide a technology capable of further appropriately adjusting the luminance of the endoscopic image. [Solution] Provided is an image processing device including: a peak detection unit configured to detect a first peak and a second peak in sequence from a high luminance side from a number-of-pixel distribution for each luminance of an endoscopic image based on imaging by an image sensor; and an exposure control unit configured to perform exposure control on a basis of a first luminance difference between the first peak and the second peak.
Claims15
The image processing device according to claim 1,
- wherein the exposure control unit performs the exposure control by acquiring a first correction value of a parameter for controlling exposure on a basis of the first luminance difference, and correcting the parameter on a basis of the first correction value.
The image processing device according to claim 1,
- wherein the exposure control unit performs the exposure control in a case that the first luminance difference is greater than a threshold.
The image processing device according to claim 1,
- wherein the exposure control unit performs the exposure control in a case that the number of pixels of the first peak exceeds a predetermined number of pixels.
An image processing method comprising:
- detecting a first peak and a second peak in sequence from a high luminance side from a number-of-pixel distribution for each luminance of an endoscopic image based on imaging by an image sensor;
- and
- performing exposure control by a processor on a basis of a first luminance difference between the first peak and the second peak.
A program for causing a computer to function as an image processing device comprising:
- a peak detection unit configured to detect a first peak and a second peak in sequence from a high luminance side from a number-of-pixel distribution for each luminance of an endoscopic image based on imaging by an image sensor;
- and
- an exposure control unit configured to perform exposure control on a basis of a first luminance difference between the first peak and the second peak.
An image processing system comprising:
- a light source unit configured to emit light;
- an image sensor configured to capture an endoscopic image by receiving reflected light of the light emitted by the light source unit;
- and
- an image processing device including
- a peak detection unit configured to detect a first peak and a second peak in sequence from a high luminance side from a number-of-pixel distribution for each luminance of the endoscopic image, and
- an exposure control unit configured to perform exposure control on a basis of a first luminance difference between the first peak and the second peak.
