Abstract
An image processing device including: a color correction section that is input with an RGB signal, and performs color correction on the RGB signal; a YC conversion section that converts the color corrected RGB signal to a first brightness signal and a color difference signal; a Y conversion section that is input with the RGB signal, and generates a second brightness signal from the RGB signal; a processor configured to execute a process, the process including computing a ratio at which to combine the first brightness signal and the second brightness signal based on the RGB signal; and a combining section that combines the first brightness signal and the second brightness signal at the computed ratio.
Claims20
An image processing device, comprising:
- a color correction section that is input with an RGB signal, and performs color correction on the RGB signal;
- a YC conversion section that converts the color corrected RGB signal to a first brightness signal and a color difference signal;
- a Y conversion section that is input with the RGB signal, and generates a second brightness signal from the RGB signal;
- a processor configured to execute a process, the process comprising computing a ratio at which to combine the first brightness signal and the second brightness signal based on the RGB signal;
- and
- a combining section that combines the first brightness signal and the second brightness signal at the computed ratio.
An image processing method, comprising:
- by a color correction section input with an RGB signal, performing color correction on the RGB signal;
- by a YC conversion section, converting the color corrected RGB signal to a first brightness signal and a color difference signal;
- by a Y conversion section input with the RGB signal, generating a second brightness signal from the RGB signal;
- by a processor, computing a ratio at which to combined the first brightness signal and the second brightness signal based on the RGB signal;
- and
- by a combining section, combining the first brightness signal and the second brightness signal using the computed ratio.
A non-transitory recording medium storing an image processing program that causes a computer to execute a process, the process comprising:
- computing a ratio based on an RGB signal, when combining, in a combining section, a first brightness signal that has been converted by a YC conversion section from the RGB signal, which has been color corrected by a color correction section, with a second brightness signal that has been generated by a Y conversion section from the RGB signal.
