Abstract

A button processing method and a data processing apparatus that improve the operability of buttons when a display device with a display screen of small size is employed. In cases where an output image includes a button, when a display image is displayed on a display device with a small display device size, e.g., 6.5 inches, the size of the button in an image space is enlarged n times at a button enlargement ratio determined in accordance with the display device size. In contrast, when a display image is displayed on the display device with a larger display device size, e.g., 8 inches, the size of the button in an image space is enlarged, e.g., n/1.23 times at a button enlargement ratio determined in accordance with the display device size. That is, the smaller the size of the display screen of the display device, the larger the enlargement ratio of the size of the button in the image space, so that the button is displayed in predetermined size on the display device regardless of the display screen size of the display device.

3. A button processing method for displaying a button and receiving an operation corresponding to the displayed button via an input device, comprising:

setting a receipt area of a button-enlargement-operation around a button whose display size on a display device is smaller than a predetermined size; and

enlarging a button whose button-enlargement-operation receipt area has been set to display an enlarged button on the display device in accordance with a position operation of a point within said button-enlargement-operation receipt area via the input device.

4. A button processing method for displaying a button and receiving an operation corresponding to the displayed button via an input device, comprising:

setting a receipt area of a button operation including the button and surroundings thereof, for a button whose display size on a display device is smaller than a predetermined size;

if a position operation of a point is performed within said button-operation receipt area via the input device when a single button-operation receipt area including the operated point exists, receiving the operation of the button whose button-operation receipt area has been set; and

if the position operation of the point is performed within a plurality of button-operation receipt areas via the input device, receiving the operation of the button having the shortest distance to the operated point among the plurality of buttons whose button-operation receipt areas include the operated point.

5. A button processing method for displaying a button and receiving an operation corresponding to the displayed button via an input device, comprising:

setting a receipt area of a button operation including the button and surroundings thereof, for a button whose display size on a display device is smaller than a predetermined size;

if a position operation of a point is performed within the button-operation receipt area via the input device when a single button-operation receipt area including the operated point exists, receiving the operation of the button whose button-operation receipt area has been set; and

if the position operation of the point is performed within a plurality of button-operation receipt areas via the input device, enlarging the plurality of buttons whose button-operation receipt areas include the operated point to display the enlarged buttons on the display device.

6. A data processing apparatus for displaying a button on a display device in accordance with a button area definition for specifying size and arrangement of the button in an image space, and for receiving an operation corresponding to the displayed button via an input device to execute processing corresponding to the button whose operation is received, the apparatus comprising:

a button enlargement ratio setting unit that, when a size of a display screen of the display device is smaller than a predetermined screen size, sets an enlargement ratio of a button in such a manner that the smaller the display screen size, the larger the ratio; and

a button enlargement display processor for enlarging a button whose display size on the display device is smaller than a predetermined size at said button enlargement ratio to display the enlarged button on the display device, the display size of the button being defined according to the display screen size and the size of the button in the image space specified by at least the button area definition.

7. The data processing apparatus according to claim 6, wherein said data processing apparatus is adapted to display a button in accordance with the button area definition recorded in a DVD-Video disc as highlight information, and to reproduce video presentation data recorded in the DVD-Video disc in accordance with the user'"'"'s operation of the button.
