Display control device, display control method, and display control program
First Claim
1. A display control apparatus that performs display control on a touch-panel-incorporated display panel, the display control apparatus comprising:
- a processor and a memory, the processor being configured to;
store in the memory user information indicating whether the user is right-handed or left-handed;
acquire touch operation information from the touch panel;
determine whether or not the user is performing a pinch-out operation by using the user'"'"'s hand based on the acquired touch operation information;
estimate, upon determining that the user is performing a pinch-out operation, a region between a plurality of finger touch regions where the user is performing the pinch-out operation in a display region of the display panel as a target region which is a region of interest of the user;
set a brightness level of a non-target region to be lower than a set brightness level, the non-target region being a region other than the target region estimated in the display region, wherein the user is determined to be performing the pinch-out operation when a distance between a first touch region and a second touch region is less than a predetermined threshold, wherein the distance is measured between a first point and a second point, the first point is a point of the first touch region closest to the second touch region and a second point is a point of the second touch region closest to the first touch region;
estimate, a region between the first touch region and the second touch region as the target region, the first touch region being a region having a largest area in the touch regions indicated by the touch operation information, the second touch region being a region having a second largest area in the touch regions;
estimate a touch region and a region away from a right end point of the corresponding touch region in a rightward direction by a predetermined distance or more as hidden regions that are hidden by the user'"'"'s hand when the user is right-handed;
estimate a touch region and a region away from a left end point of the corresponding touch region in a leftward direction by a predetermined distance or more as the hidden regions when the user is left-handed; and
designate the estimated hidden regions as the non-target region.

Abstract
This display control device can effectively reduce power consumption while assuring visibility of a display area. A display control device (400) carries out display control for a display panel with an integrated touch panel and has: a touch operation information acquisition unit (410) that acquires touch operation information from the touch panel; a user operation information estimation unit (420) that estimates a region of interest, which is a region that a user is giving attention to, from the display region on the display panel on the basis of the touch operation information that is acquired; and a display control indication unit (440) that sets the brightness level for regions of non-interest, which is a region other than the region of interest estimated within the display region, lower than the set brightness level.

6. A display control method of performing display control on a touch-panel-incorporated display panel, the display control method comprising:
-
storing user information indicating whether a user is right-handed or left-handed; acquiring touch operation information from the touch panel; determining whether or not the user is performing a pinch-out operation by using the user'"'"'s hand based on the acquired touch operation information; estimating, upon determining that the user is performing a pinch-out operation, a region between a plurality of finger touch regions where the user is performing the pinch-out operation in a display region of the display panel, as a target region which is a region of interest of the user; setting a brightness level of a non-target region to be lower than a set brightness level, the non-target region being a region other than the target region estimated in the display region, wherein the estimation of the target region includes determining that the user is performing the pinch-out operation when a distance between a first touch region and a second touch region is less than a predetermined threshold, and wherein the distance is measured between a first point and a second point, the first point is a point of the first touch region closest to the second touch region and a second point is a point of the second touch region closest to the first touch region; estimating a region between the first touch region and the second touch region as the target region, the first touch region being a region having a largest area in the touch regions indicated by the touch operation information, the second touch region being a region having a second largest area in the touch regions; estimating a touch region and a region away from a right end point of the corresponding touch region in a rightward direction by a predetermined distance or more as hidden regions that are hidden by the user'"'"'s hand when the user is right-handed; estimating a touch region and a region away from a left end point of the corresponding touch region in a leftward direction by a predetermined distance or more as the hidden regions when the user is left-handed; and designating the estimated hidden regions as the non-target region.
