Abstract
An image processing apparatus acquires a color image including a plurality of primary color signals, performs color space conversion processing on the color image to generate a brightness signal image and a color difference signal image, performs super-resolution processing on the brightness signal image and the color difference signal image to generate a prediction brightness signal image, and uses the prediction brightness signal image to generate a super-resolution color image in which a resolution of the color image is increased.
Claims17
An image processing apparatus comprising:
- a processor configured to:
- acquire a color image including a plurality of primary color signals;
- perform color space conversion processing on the color image to generate a brightness signal image and a color difference signal image;
- perform super-resolution processing on the brightness signal image and the color difference signal image to generate a prediction brightness signal image;
- and
- use the prediction brightness signal image to generate a super-resolution color image in which a resolution of the color image is increased.
An image processing method comprising:
- a step of acquiring a color image including a plurality of primary color signals;
- a step of performing color space conversion processing on the color image to generate a brightness signal image and a color difference signal image;
- a step of performing super-resolution processing on the brightness signal image to generate a prediction brightness signal image;
- and
- a step of using the prediction brightness signal image to generate a super-resolution color image in which a resolution of the color image is increased.
A non-transitory computer readable medium for storing a computer-executable program for causing a computer to function as an image processing apparatus, the computer-executable program causing the computer to execute:
- a function of acquiring a color image including a plurality of primary color signals;
- a function of performing color space conversion processing on the color image to generate a brightness signal image and a color difference signal image;
- a function of performing super-resolution processing on the brightness signal image to generate a prediction brightness signal image;
- and
- a function of using the prediction brightness signal image to generate a super-resolution color image in which a resolution of the color image is increased.
An endoscope system comprising:
- an endoscope that images a subject to generate an endoscope image;
- a display that displays the endoscope image;
- and
- an image processing apparatus that includes a processor and generates a super-resolution endoscope image in which a resolution of the endoscope image is increased,
- wherein the processor is configured to:
- acquire the endoscope image as a color image;
- generate the super-resolution endoscope image in which the resolution of the endoscope image is increased;
- and
- perform control of displaying the super-resolution endoscope image on the display.
