Abstract

A controller 103, based on the positional information of the display image, selects whether the 3-dimensional image data decoded by a decoder 102 is displayed stereoscopically (in 3-dimensional display mode) or planarly (in 2-dimensional display mode) and gives notice of the selected display mode to a display portion 104. Specifically, the input positional information=display address is monitored, and if no temporal change occurs, namely if the displayed position of the image data does not change, 3-dimensional display mode is selected as the display mode. On the other hand, if there is a temporal change, namely if the displayed position of the image data varies by scrolling, 2-dimensional display mode is selected as the display mode. Thus, an image data display apparatus which can efficiently display image data on a display when display of 3-dimensional image data is scrolled is provided.

Claims

1. An image data display apparatus capable of switching a display of an input 3-dimensional image data between a stereoscopic representation or a planar representation, comprising:

a display means capable of displaying the 3-dimensional image data in a manner switchable between a 3-dimensional representation and a 2-dimensional representation;

an image converting means for converting, when a displayed position of the 3-dimensional image data is moving, the moving 3-dimensional image data into a 2-dimensional image data; and

a control means for switching a display mode of the display means between a 3-dimensional display mode and a 2-dimensional display mode.

5. The image data display apparatus according to claim 1, wherein the 3-dimensional image data previously includes a 2-dimensional select image information for selecting one viewpoint image data from a plurality of viewpoints image data, and the image converting means selects a 2-dimensional image based on the 2-dimensional select image information.

6. The image data display apparatus according to claim 1, wherein the image converting means fixedly selects a predetermined single viewpoint image data as a 2-dimensional image.

7. The image data display apparatus according to claim 1, wherein the image converting means converts the 3-dimensional image data so that a plurality of viewpoints image data become identical, and displays the converted image data in the 3-dimensional display mode.
