Abstract
An image processing apparatus includes an image quality correction circuit for correcting an image quality of input video data by enhancing the input video data and a control circuit for controlling the image quality correction circuit. The control circuit detects a signal level of a high-frequency component of the input video data and controls the image quality correction circuit in response to the signal level detection result so that the degree of enhancement of the input video data is increased in response to an increase in the signal level of the high-frequency component.
Claims9
An image processing apparatus comprising:
- an image quality corrector for correcting an image quality of input video data by enhancing the input video data;
- and
- a controller for controlling the image quality corrector, the controller detecting a signal level of a high-frequency component of the input video data and controlling the image quality corrector in response to the signal level detection result so that the degree of enhancement of the input video data is increased in response to an increase in the signal level of the high-frequency component.
An image processing method comprising steps of:
- correcting an image quality of input video data by enhancing the input video data;
- detecting a signal level of a high-frequency component of the input video data;
- and
- performing a control process in response to the signal level detection result so that the degree of enhancement of the input video data is increased in response to an increase in the signal level of the high-frequency component.
A computer program for causing a computer to correct image quality of input video data, comprising steps of:
- correcting an image quality of input video data by enhancing the input video data;
- detecting a signal level of a high-frequency component of the input video data;
- and
- performing a control process in response to the signal level detection result so that the degree of enhancement of the input video data is increased in response to an increase in the signal level of the high-frequency component.
A recording medium storing a computer program for causing a computer to correct image quality of input video data, the computer program comprising steps of:
