Abstract

A reproducing apparatus, an image data reproducing method, a program, and a storage medium each detects an attitude state of the reproducing apparatus, extracts a part of an area of image data obtained by an image pickup device, and reproduces the part of the area of the extracted image data. According to the detection result, the part of the area of the image data is changed to another part of the area and rotation processing of another part of the area is performed, thereby reproducing the another part of the area which was subjected to the rotation processing.

Claims

1. A display control apparatus comprising:

a display control unit configure to control to enlargingly display a partial area of image data;

a change-over instruction accepting unit configured to accept an instruction to change over display of the image data from enlargement display of the partial area of the image data by the display control unit to enlargement display of a partial area of other image data; and

a control unit configured to control the display control unit in accordance with the instruction being accepted by the change-over instruction accepting unit to enlargingly display the partial area of the other image data such that the specific position (a1, b1) of the enlargingly-displayed partial area of the image data before the change-over, sizes Y1 and X1 in respective longitudinal and lateral directions in a display direction of the image data before the change-over, the specific position (a2, b2) of the partial area to be enlargingly displayed in the other image data, and sizes Y2 and X2 in longitudinal and lateral directions in the display direction of the other image data satisfy together following relationships;

a2=(X2/X1)×

a1

b2=(Y2/Y1)×

b1.

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

controlling to enlargingly display a partial area of image data;

accepting an instruction to change over display of the image data from enlargement display of the partial area of the image data in the enlarging-display controlling step to enlargement display of a partial area of other image data; and

controlling the enlarging-display controlling step in accordance with the instruction being accepted in the change-over instruction accepting step to the enlargingly display the partial area of the other image data such that the specific position (a1, b1) of the enlargingly-displayed partial area of the image data before the change-over, sizes Y1 and X1 in respective longitudinal and lateral directions in a display direction of the image data before the change-over, the specific position (a2, b2) of the partial area to be enlargingly displayed in the other image data, and sizes Y2 and X2 in longitudinal and lateral directions in the display direction of the other image data satisfy together following relationships;

a2=(X2/X1)×

a1

b2=(Y2/Y1)×

b1.

3. A non-transitory computer-readable storage medium storing thereon a computer program comprising a program code for causing a computer to execute a control method of a display control apparatus, the program code comprising:

controlling to enlargingly display a partial area of image data;

accepting an instruction to change over display of the image data from enlargement display of the partial area of the image data in the enlarging-display controlling step to enlargement display of a partial area of other image data; and

controlling the enlarging-display controlling step in accordance with the instruction being accepted in the change-over instruction accepting step to the enlargingly display the partial area of the other image data such that the specific position (a1, b1) of the enlargingly-displayed partial area of the image data before the change-over, sizes Y1 and X1 in respective longitudinal and lateral directions in a display direction of the image data before the change-over, the specific position (a2, b2) of the partial area to be enlargingly displayed in the other image data, and sizes Y2 and X2 in longitudinal and lateral directions in the display direction of the other image data satisfy together following relationships;

a2=(X2/X1)×

a1

b2=(Y2/Y1)×

b1.
