Abstract

Control is made in such that in a case where an attitude detected by an attitude detection unit is a first attitude, if a trace of a detected touched position satisfies a specific condition, a function corresponding to the detected trace is executed, and in a case where the detected attitude is a second attitude opposite to the first attitude, even if the trace of the detected touched position is a trace which satisfies the specific condition, the corresponding function is not executed. Thus, when an electronic apparatus is upside-down, a specific gesture operation by a touch operation is invalidated.

Claims

1. An electronic apparatus comprising:

an attitude detection unit;

a touch detection unit; and

a control unit configured to control in such a manner that

in a ease where an attitude detected by the attitude detection unit is a first attitude, if a trace of a touched position detected by the touch detection unit satisfies a specific condition, a specific function corresponding to the detected trace is executed, and

in a case where the attitude detected by the attitude detection unit is a second attitude upside-down turned from the first attitude, the specific function corresponding to a trace of a touched position detected by the touch detection unit is not executed.

2. The apparatus according to claim 1, wherein the specific condition is that one directional component of the trace is moved by a predetermined distance or longer, and in a case where the trace is moved by a predetermined distance or longer in an opposite direction, a different function is assigned.

3. The apparatus according to claim 2, wherein the trace which satisfies the specific condition is a trace based on such a condition that it is a trace of two or more dimensions.

4. The apparatus according to claim 3, wherein the specific trace is a trace for depicting a character.

5. The apparatus according to claim 1, wherein the trace which satisfies the specific condition does not include a trace of a pinch, and wherein the pinch is an operation of touching a plurality of positions simultaneously, and narrowing or widening an interval between the plurality of positions, irrelevant to moving directions of the plurality of positions.

6. The apparatus according to claim 5,

wherein the control unit configured

(a) in a case where an attitude detected by the attitude detection unit is the first attitude, to execute the specific function when the touch detection unit detects a trace which satisfies the specific condition,

(b) in a case where an attitude detected by the attitude detection unit is the first attitude, to execute an enlargement control of the displayed image or a reduction control of the displayed image when the touch detection unit detects a trace of the pinch,

(c) in a case where an attitude detected by the attitude detection unit is the second attitude, the specific function corresponding to any trace of a touched position detected by the touch detection unit is not executed,

(d) in a case where an attitude detected by the attitude detection unit is the second attitude, to execute the enlargement control or the reduction control when the touch detection unit detects a trace of the pinch.

7. The apparatus according to claim 1, wherein the control unit controls in such that in a case where the attitude detected by the attitude detection unit is the second attitude, a button arranged to activate the specific function is displayed to a display unit.

8. The apparatus according to claim 1, wherein the control unit controls in such that in a case where the attitude detected by the attitude detection unit is the second attitude, a guidance indicating that the specific function corresponding to the trace of a touched position detected by the touch detection unit is not executed when the attitude is the second attitude is displayed to a display unit.

9. The apparatus according to claim 1, wherein at the time of a photographing, the attitude detection unit detects the attitude, and at the time of an image confirmation after the photographing, the attitude detection unit does not detect the attitude but retains information detected at the time of the photographing.

10. The apparatus according to claim 1, wherein the attitude detection unit executes an attitude detection processing for a period of time from an activation of the electronic apparatus to completion thereof.

11. The apparatus according to claim 1, further comprising a grip portion.

12. The apparatus according to claim 1, wherein the specific function is a function of changing from an image displayed on the display unit into another image.

13. A control method of an electronic apparatus, comprising:

an attitude detection step;

a touch detection step; and

a control step of controlling in such a manner that

in a case where an attitude detected in the attitude detection step is a first attitude, if a trace of a touched position detected in the touch detection step satisfies a specific condition, a specific function corresponding to the detected trace is executed, and

in a case where the attitude detected in the attitude detection step is a second attitude upside-down turned from the first attitude, the specific function corresponding to a trace of a touched position detected in the touch detection step is not executed.

14. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method of an electronic apparatus, the control method comprising:

an attitude detection step;

a touch detection step; and

a control step of controlling in such a manner that

in a case where an attitude detected in the attitude detection step is a first attitude, if a trace of a touched position detected in the touch detection step satisfies a specific condition, a specific function corresponding to the detected trace is executed, and

in a case where the attitude detected in the attitude detection step is a second attitude upside-down turned from the first attitude, the specific function corresponding to a trace of a touched position detected in the touch detection step is not executed.
