This predetermined threshold value can be the least, and the absolute value of the difference of pixel value is almost identical less than the difference of this threshold value pixels illustrated value, then
Illustrate that the left side of this picture frame can be spliced mutually with right side, then this image is judged as panoramic picture.
Further, when image be not belonging to 3d image be also not belonging to panoramic picture time, this image is judged as 2d image.
Specifically, it is judged that whether picture frame exists parallax between left-half and the right half part of symmetry, it may be judged whether
The method that there is parallax can be the scheme of any judgement parallax in prior art, when left-half and the symmetrical right side in picture frame
When there is not parallax between half part, it is judged that whether exist between top half and the latter half of symmetry in picture frame and regard
Difference, and when there is not parallax between the top half in picture frame and the latter half of symmetry, it is judged that image is not belonging to 3d
Image.
Further, according to the Pixel Information of picture frame edge columns, it is judged that whether this image is panoramic picture, including acquisition figure
As the pixel of frame left side edge string, and the pixel of edge, rightmost side string, when being positioned at the picture of correspondence position in these two row
Vegetarian refreshments pixel value differs, or when the absolute value of the difference of pixel value is higher than predetermined threshold value, it is judged that image is not belonging to panoramic picture.
Now, image is judged as 2d image.
Step S3, according to image type, automatically select the broadcast mode of correspondence.
Including when judging that image is 2d image, automatically select 2d play mode, when judging that image is 3d image, automatically
Select 3d play mode, it is judged that when image is panoramic picture, automatically select panorama play mode.
In a kind of possible implementation, the embodiment of the present invention can also include the step changing image type
Suddenly, such as when existing player does not possess certain broadcast mode (such as 3d or panorama broadcast mode), this image type can be turned
It is changed to 2d image, and plays out by 2d pattern.Such as can only play among its left-eye view or right-eye view to regard
Figure.
