[1] Purpose of this embodiment [2] Hardware configuration of information processing apparatus [3] Functional configuration of information processing apparatus [4] Operation of information processing apparatus

[1] Object of this embodiment First, the object of the embodiment of the present invention will be described. In recent years, in a display device such as a computer display, it is possible to adjust the brightness, hue, and the like of the display screen so that an optimal display is performed on the display screen. As a method for adjusting the image quality parameter, the user can select an image quality parameter for correcting the image quality so that an optimal display is performed, or set the image quality parameter in advance according to the type of the LCD panel. It is done.

  Since the plurality of image quality parameters are related to each other, for example, when the color temperature setting on the display screen is changed, the color setting is changed according to the changed color temperature setting. In order to obtain an optimum image quality on the display screen, it is necessary to set not only the color temperature and color settings but also various image quality parameters for setting contrast, gamma characteristics, and the like. Since these parameters depend on each other, when one parameter is changed, it is necessary to change other parameters in accordance with the change of the parameter.

  Also, since the appropriate image quality parameter settings differ for each LCD panel and application, it is necessary to change multiple image quality parameters after comprehensively considering the LCD panel being used, the application being started, etc. There is. When setting each image quality parameter by user input, the user must understand the meaning of each image quality parameter and comprehensively consider the LCD panel, running applications, and the like. In particular, there is a problem that it is difficult for the user to appropriately set the image quality parameter for each application because the optimum image quality parameter setting differs depending on the running application.

  FIG. 10 is an explanatory diagram for explaining conventional image quality correction. Conventionally, as shown in FIG. 10, image quality correction is performed based on setting values of image quality parameters set in Graphics Device Driver (graphics device driver) or BIOS (Basic Input / Output System).

  Then, a still image or a moving image content is displayed on an LCD (Liquid Crystal Display: liquid crystal display monitor) via Graphics (graphics), which is hardware for displaying the content. Image quality correction by a driver includes correction for still image content and correction for moving image content, and the setting method differs for each driver. That is, the image quality parameter setting cannot be changed for each LCD panel, and the image quality parameter setting cannot be changed for each graphic to be used.

  Also, it is possible to change the setting of the image quality parameter according to the panel identification information of the BIOS. However, in this case, it is necessary to change the setting value table of the BIOS binary to change the setting of the image quality parameter. Furthermore, since the image quality correction by the driver and the image quality correction by the BIOS are set independently, it is extremely difficult for the user to set the image quality parameter to an appropriate value.

Thereby, it is possible to easily set various image quality parameters depending on each other only by selecting an image quality mode.

  Alternatively, a predetermined number of image quality modes may be prepared, and the user may select a desired image quality mode from the predetermined number of image quality modes. As a result, the user can easily optimize the image quality setting without being aware of the existence of each image quality parameter.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.

  For example, in the above-described embodiment, the application program being activated is determined, but the present invention is not limited to such an example. For example, the application program API may be used to determine the mode of the running application program. For example, one application program may have a mode in which a plurality of media such as a television broadcast and a DVD can be reproduced. In this case, it is possible to determine which mode the application program is in and set the image quality parameter according to the mode.

  Further, the format of content data may be determined using an application program or an API of a video driver. For example, the content data is HD or SD, or the color gamut of the content data is ITU-R BT. 709 or ITU-R BT. Whether it is 601 or xvYcc is determined. Then, an image quality parameter corresponding to the determined format of the content data may be set.
