Abstract

An electronic apparatus includes a touch detection unit that detects a touch operation on a touch panel, a selection unit that selects positions on a display unit via a touch operation on the touch panel, and a control unit that controls the selection unit, wherein, in a case where a touch position movement is performed on the touch panel, the control unit controls the selection unit to select, from among positions of a plurality of selective candidates on the display unit existing in a direction of the touch position movement from a starting position of the touch position movement to a touch position at a first timing, positions based on a touch position movement up to a second timing after the first timing.

First claim

What is claimed is:

1 . An electronic apparatus comprising:
a touch detection unit configured to detect a touch operation on a touch panel; a selection unit configured to select positions on a display unit via a touch operation on the touch panel; and a control unit configured to control the selection unit, wherein, in a case where a touch position movement is performed on the touch panel, the control unit controls the selection unit to select, from among positions of a plurality of selective candidates on the display unit existing in a direction of the touch position movement from a starting position of the touch position movement to a touch position at a first timing, positions based on a touch position movement up to a second timing after the first timing.

2 . The electronic apparatus according to claim 1 , further comprising a determination unit configured to determine some of all of positions on the display unit as selective candidates based on the direction of the touch position movement from the starting position of the touch position movement to the touch position at the first timing.

3 . The electronic apparatus according to claim 2 , wherein, from all of the positions on the display unit, the determination unit does not consider positions not existing in the movement direction as selective candidates.

4 . The electronic apparatus according to claim 1 , wherein the control unit controls the selection unit to select, from the plurality of selective candidates, positions of selective candidates closest to passage positions corresponding to movement from a position selected at a timing of starting the touch position movement to the touch position up to the second timing.

5 . The electronic apparatus according to claim 1 , wherein the control unit controls the selection unit to select positions of selective candidates at positions away from a position selected at a timing of starting the touch position movement based on an amount of movement from the touch position at the timing of starting the touch position movement to the touch position up to the second timing.

6 . The electronic apparatus according to claim 1 , wherein, in a case where the touch position is moving faster than a predetermined speed, the control unit controls the selection unit to select positions based on the touch position movement up to the second timing from the positions of the plurality of selective candidates.

7 . The electronic apparatus according to claim 1 , wherein, in a case where the touch position is moving slower than a predetermined speed and the touch position movement is performed on the touch panel, the control unit controls the selection unit to select positions based on the touch position movement up to the second timing.

8 . The electronic apparatus according to claim 1 , further comprising a setting unit configured to enable setting either an absolute coordinate setting for selecting a position on the display unit corresponding to the touch starting position on the touch panel or a relative coordinate setting for selecting passage positions corresponding to an amount of the touch position movement on the touch panel from a position selected at a timing of starting a touch without selecting a position corresponding to the touch starting position,
wherein, in a case of the relative coordinate setting, the control unit controls the selection unit to select the position based on the touch position movement up to the second timing out of the positions of the plurality of selective candidates, and wherein, in a case of the absolute coordinate setting, the control unit controls the selection unit to select positions based on the touch position movement up to the second timing.

9 . The electronic apparatus according to claim 8 , wherein the control unit controls the display unit to display an item indicating the position selected on the display unit.

10 . The electronic apparatus according to claim 9 , wherein, in a case where a touch position movement is performed on the touch panel when the item is not superimposed on the touch panel, the control unit controls the selection unit to select positions based on the touch position movement up to the second timing from the positions of the plurality of selective candidates.

11 . The electronic apparatus according to claim 9 ,
wherein the electronic apparatus is connectable to an external display apparatus of the electronic apparatus, and wherein, in a case where a touch position movement is performed on the touch panel when the item is displayed on the external display apparatus, the control unit controls the selection unit to select positions based on the touch position movement up to the second timing from the positions of the plurality of selective candidates.

12 . The electronic apparatus according to claim 1 ,
wherein, in a case where the display unit and the touch panel are provided as separate units, the control unit controls the selection unit to select positions based on the touch position movement up to the second timing from the positions of the plurality of selective candidates when a touch position movement is performed on the touch panel, and wherein, in a case where the display unit and the touch panel are provided as one unit, the control unit controls the selection unit to select positions based on the touch position movement up to the second timing when a touch position movement is performed on the touch panel.

13 . The electronic apparatus according to claim 1 , further comprising an approach detection unit configured to detect an approach of an object to a finder that enables visually recognizing the display unit,
wherein, in a case where a touch position movement is performed on the touch panel when the approach detection unit is detecting the approach, the control unit controls the selection unit to select positions based on the touch position movement up to the second timing from the positions of the plurality of selective candidates.

14 . The electronic apparatus according to claim 1 , wherein, after positions of the plurality of selective candidates are determined, selective positions derived via the touch position movement are some of the plurality of selective candidates until a touch operation satisfies a predetermined condition.

15 . The electronic apparatus according to claim 14 , wherein the predetermined condition is that a speed of the touch position movement becomes lower than a predetermined speed.

16 . The electronic apparatus according to claim 1 , wherein the direction of the touch position movement from the starting position of the touch position movement to the touch position at the first timing is determined based on a horizontal and a vertical component of a movement amount of a movement within a predetermined time period since a start of the touch position movement.

17 . The electronic apparatus according to claim 1 , wherein the plurality of selective candidates are determined at the first timing.

18 . The electronic apparatus according to claim 1 , wherein candidate items indicating selective positions derived via the touch position movement are displayed on the display unit, and the candidate items are displayed in a grid pattern along a horizontal and a vertical direction.

19 . The electronic apparatus according to claim 18 , wherein, from among the candidate items, candidate items existing on a straight line based on a direction of the movement from the starting position of the touch position movement to the touch posi
