Abstract

A display apparatus including a display unit, adapted to playback a sequence of images, comprises: a detection configured to detect an attitude of the display apparatus or the display unit; a control unit configured to control the display unit to pause playback of the sequence of images, if the detected attitude of the display apparatus is not substantially aligned with the orientation of an image to be displayed.

Claims

1. A display apparatus comprising:

a display unit configured to play back a sequence of images on the display unit;

a detection unit configured to detect an attitude of the display apparatus or the display unit;

an obtaining unit configured to obtain orientation information whether an image to be displayed is a landscape image or a portrait image; and

a control unit configured to control the display unit to, in either one of a case where the attitude detected by the detection unit is horizontally-oriented and the orientation information obtained by the obtaining unit indicates that the image to be displayed is the portrait image, and a case where the attitude detected by the detection unit is vertically-oriented and the orientation information obtained by the obtaining unit indicates that the image to be displayed is the landscape image, pause playback of the sequence of images and display said sequence of images in a reduced state against when said sequence of images is not rotated and in a rotated state according to the attitude detected by the detection unit, and display an item to start playback of said sequence of images, even when playback of the sequence of images is started, wherein the control unit is configured to start playback of said sequence of images in the rotated and the reduced state when the s operated.

2. An apparatus according to claim 1,

wherein the control unit controls the display unit, so that an image to be displayed is oriented according to the attitude detected by the detection unit and the orientation information obtained by the obtaining unit.

3. An apparatus according to claim 1, wherein the orientation information obtained by the obtaining unit is determined based on information included with the image indicating the attitude of an image pickup apparatus upon capturing the image to be displayed.

4. An apparatus according to claim 1, wherein, if, after pausing of the playback of the sequence of images, the detection unit detects a change in the attitude of the display apparatus or the display unit, the control unit controls the display unit to, in none of a case where the attitude detected by the detection unit is horizontally-oriented and the orientation information obtained by the obtaining unit indicates that the image to be displayed is the portrait image, and a case where the attitude detected by the detection unit is vertically-oriented and the orientation information obtained by the obtaining unit indicates that the image to be displayed is the landscape image, resume playback of the image to be displayed even when the item is not operated.

5. An apparatus according to claim 1, wherein in a case where the orientation of a current image to be displayed coincides with the orientation of a preceding image displayed, and the attitude detected by the detection unit at the time of the playback of the preceding image is the same as the attitude detected by the detection unit when playing back the current image, the control unit is adapted to control playback of the current image without pausing following the playback of the preceding image.

6. An apparatus according to claim 1, wherein the orientation information obtained by the obtaining unit comprises information representing a top and bottom direction of the image.

7. An apparatus according to claim 1, further arranged to display an orientation icon indicating the orientation of an image when displaying the image in the paused playback state.

8. An apparatus according to claim 1, wherein the display apparatus comprises an image pickup apparatus including an image pickup unit.

10. A non-transitory computer-readable storage medium storing a program that causes a computer to function as each unit of a display apparatus of claim 1.

11. The apparatus according to claim 1, wherein the control unit configured to control the display unit to, in either one of a case where the attitude detected by the detection unit is vertically-oriented and the orientation information obtained by the obtaining unit indicates that the image to be displayed is the portrait image, and a case where the attitude detected by the detection unit is horizontally-oriented and the orientation information obtained by, the obtaining unit indicates that the image to be displayed is the landscape image, resume playback of the sequence of images.

12. The apparatus according to claim 1, wherein the sequence of images is a moving image.

13. The apparatus according to claim 12, wherein each of the sequence of images is a frame.

14. The apparatus according to claim 1, wherein a second image of the sequence of images is played back after playing back a first image of the sequence of images, and

the control unit is configured to perforin the control when the playback of the first image is switched to the playback of the second image.

15. The apparatus according to claim 1, wherein the control unit is configured to control the display unit not to, in either one of a case where the attitude detected by the detection unit is horizontally-oriented and the orientation information obtained by the obtaining unit indicates that the image to be displayed is the landscape image, and a case where the attitude detected by the detection unit is vertically-oriented and the orientation information obtained by the obtaining unit indicates that the image to be displayed is the portrait image, pause playback of the sequence of images.

16. The apparatus according to claim 1 wherein the control unit is configured to display a stop item to stop playback of the sequence of images, when the item is operated.

17. The apparatus according to claim 1, wherein the sequence of images includes one or more landscape moving images and one or more portrait moving images in an irregular order.

9. A control method of a display apparatus including a display unit, comprising:

a displaying step of playing back a sequence of ages on the display unit;

a detection step of detecting an attitude of the display apparatus or the display unit;

an obtaining step of obtaining orientation information whether an image to be displayed is a landscape image or a portrait image; and

a control step of controlling said display unit to, in either one of a case where the attitude detected in the detection step is horizontally-oriented and the orientation information obtained in the obtaining step indicates that the image to be displayed is the portrait image, and a case where the attitude detected in the detection step is vertically-oriented and the orientation information obtained in the obtaining step indicates that the image to be displayed is the landscape image, pause playback of the sequence of images, and display said sequence of images in a reduced state against when said sequence of images is not rotated and in a rotated state according to the attitude detected by the detection step, and display an item to start playback of said sequence of images, even when playback of said sequence of images is started, wherein the control step starts playback of said sequence of images in the rotated and the reduced state when the item is operated.
