Abstract
A display control apparatus includes a touch detection unit configured to detect a touch performed on a display unit, a specifying unit configured to specify a target of specification in a predetermined region of the display unit according to a touched position, and a display control unit configured to control an object identification mark to be displayed in the predetermined region so as to indicate a first axis and a second axis that makes the target specified by the specifying unit based on the touched position of the touch become an intersection point with the first axis in response to the touch performed in the predetermined region, and control the object identification mark to be hidden when the touch is released.
Claims23
A display control apparatus comprising:
- at least memory and at least one processor that cause the display control apparatus to:
- detect a touch performed on a display unit;
- specify a specifying object in a predetermined region of the display unit according to a touched position;
- control, in response to a touch being performed in the predetermined region, to display an object identification mark in the predetermined region to indicate a first axis and a second axis, wherein an intersection point of the first axis and the second axis corresponds with the specified specifying object based on the touched position of the touch, and to hide the object identification mark when the touch is released;
- switch between a first mode in which the display control apparatus specifies a target from targets of a first type in the predetermined region and a second mode in which the display control apparatus specifies a target from targets of a second type different from the targets of the first type in the predetermined region;
- control the object identification mark not to be displayed in a case where a touch is released from a position where the touch is started before a predetermined time has passed after the touch onto the predetermined region is started;
- and
- control the object identification mark to be displayed according to a touch performed in the predetermined region in the first mode, and control the object identification mark not to be displayed even if a touch is performed in the predetermined region in the second mode.
A control method for a display control apparatus including a display unit, the method comprising:
- detecting a touch performed on the display unit;
- specifying a specifying object in a predetermined region of the display unit according to a touched position;
- controlling, in response to a touch being performed in the predetermined region, to display an object identification mark in the predetermined region to indicate a first axis and a second axis, wherein an intersection point of the first axis and the second axis corresponds with the specified specifying object based on the touched position of the touch, and to hide the object identification mark when the touch is released;
- and
- switching between a first mode in which the display control apparatus specifies a target from targets of a first type in the predetermined region and a second mode in which the display control apparatus specifies a target from targets of a second type different from the targets of the first type in the predetermined region;
- controlling the object identification mark not to be displayed in a case where a touch is released from a position where the touch is started before a predetermined time has passed after the touch onto the predetermined region is started;
- and
- controlling the object identification mark to be displayed according to a touch performed in the predetermined region in the first mode, and controlling the object identification mark not to be displayed even if a touch is performed in the predetermined region in the second mode.
A non-transitory computer-readable storage medium storing a program for executing a control method for a display control apparatus including a display unit, the method comprising:
- detecting a touch performed on the display unit;
- specifying a specifying object in a predetermined region of the display unit according to a touched position;
- controlling, in response to a touch being performed in the predetermined region, to display an object identification mark in the predetermined region to indicate a first axis and a second axis, wherein an intersection point of the first axis and the second axis corresponds with the specified specifying object based on the touched position of the touch, and to hide the object identification mark when the touch is released;
- switching between a first mode in which the display control apparatus specifies a target from targets of a first type in the predetermined region and a second mode in which the display control apparatus specifies a target from targets of a second type different from the targets of the first type in the predetermined region;
- controlling the object identification mark not to be displayed in a case where a touch is released from a position where the touch is started before a predetermined time has passed after the touch onto the predetermined region is started;
- and
- controlling the object identification mark to be displayed according to a touch performed in the predetermined region in the first mode, and controlling the object identification mark not to be displayed even if a touch is performed in the predetermined region in the second mode.
