Abstract

This invention provides a display control apparatus capable of more quickly displaying the next image while suppressing a decrease in viewability. The apparatus displays an image together with an added non-image area when displaying, in a display area of a display unit to be used to display an image, the image having an aspect ratio different from that of the display area. Upon accepting a scroll operation of instructing scroll display of the image displayed in the display area, the apparatus performs the scroll display in accordance with the scroll operation. At this time, the apparatus adjusts the non-image area to decrease the width of the non-image area in the moving direction of the scroll during execution of the scroll display as the operation amount of the accepted scroll operation increases.

Claims

1. A display control apparatus comprising:

a display control unit configured to control to display an image together with an added non-image area when displaying, in a display area of a display unit to be used to display an image, the image having an aspect ratio different from that of the display area;

an acceptance unit configured to accept a scroll operation of instructing scroll display of the image displayed in the display area;

a scroll control unit configured to control to perform the scroll display in accordance with the scroll operation accepted by said acceptance unit; and

an adjustment unit configured to adjust the non-image area to decrease a width of the non-image area in a moving direction of the scroll during execution of the scroll display as an operation amount of the scroll operation accepted by said acceptance unit increases.

2. The apparatus according to claim 1, wherein said scroll control unit controls to perform the scroll display at a higher scroll speed as the operation amount of the scroll operation accepted by said acceptance unit increases.

3. The apparatus according to claim 1, wherein said scroll control unit

performs the scroll display at a predetermined scroll speed if the operation amount of the scroll operation accepted by said acceptance unit is not more than a predetermined threshold, and

performs the scroll display at a higher scroll speed as the operation amount increases if the operation amount of the scroll operation accepted by said acceptance unit is more than the predetermined threshold.

4. The apparatus according to claim 1, wherein said adjustment unit performs adjustment to decrease the width as the number of scroll operations serving as the operation amount of the scroll operation increases.

5. The apparatus according to claim 1, wherein

said acceptance unit accepts a flick operation on a touch panel as the scroll operation, and

said adjustment unit performs adjustment to decrease the width as a moving speed of touch by the flick operation serving as the operation amount of the scroll operation increases.

6. The apparatus according to claim 1, wherein

said acceptance unit accepts a rotational operation on an operation member as the scroll operation, and

said adjustment unit performs adjustment to decrease the width as a rotational speed by the rotational operation serving as the operation amount of the scroll operation increases.

7. The apparatus according to claim 1, wherein if the operation amount of the scroll operation is more than a predetermined threshold, said adjustment unit sets the width to a fixed width independently of the operation amount of the scroll operation more than the predetermined threshold.

8. The apparatus according to claim 1, wherein if a non-operation time of the scroll operation not less than a predetermined time has elapsed, said adjustment unit further decreases the width in accordance with the non-operation time.

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

9. A method of controlling a display control apparatus, comprising the steps of:

controlling to display an image together with an added non-image area when displaying, in a display area of a display unit to be used to display one image, the image having an aspect ratio different from that of the display area;

accepting a scroll operation of instructing scroll display of the image displayed in the display area;

controlling to perform the scroll display in accordance with the scroll operation accepted in the accepting step; and

adjusting the non-image area to decrease a width of the non-image area in a moving direction of the scroll during execution of the scroll display as an operation amount of the scroll operation accepted in the accepting step increases.
