Abstract
In order to attain an object to provide a display device capable of suppressing electric power consumption as well as displaying an image with excellent quality, a control device includes a control information output section (36) for, in a case where an image determining section (35) determines that an image is a flickering image, supplying, to a grayscale level control section (80), grayscale level control information for causing the grayscale level control section to carry out control for increasing or lowering a grayscale level of a pixel in which flicker is easily recognizable.
Claims14
A control device for a display device,
- said control device comprising:
- an image determining section for determining whether or not an image is a flickering image which has a characteristic of causing flicker to be easily recognizable;
- and
- a control information output section for, in a case where the image determining section determines that the image is the flickering image, supplying, to a grayscale level control section for carrying out control for changing a grayscale level of the flickering image, grayscale level control information for causing the grayscale level control section to carry out control for increasing or lowering a grayscale level of at least one pixel in which the flicker is easily recognizable.
A method for controlling a display device,
- said method comprising the steps of:
- a) determining whether or not an image is a flickering image which has a characteristic of causing flicker to be easily recognizable;
- and
- b) in a case where it is determined in the step a) that the image is the flickering image, supplying, to a grayscale level control section for carrying out control for changing a grayscale level of the flickering image, grayscale level control information for causing the grayscale level control section to carry out control for increasing or lowering a grayscale level of a pixel in which the flicker is easily recognizable.
