Electronic apparatus and stereoscopic image display method thereof

An electronic apparatus, comprising:

• a transceiver, configured to receive a streaming image;
• a stereoscopic display;
• and
• at least one processor, coupled to the transceiver and the stereoscopic display, and configured to:
• obtain a display frame comprising a streaming image;
• extract at least one rectangular image region in the display frame by executing edge detection and straight line detection;
• executing a watermark detection to detect whether a watermark appears in the at least one rectangular image region, wherein the watermark is configure to indicate that the streaming image within one of the at least one rectangular image region conforms to a stereoscopic image format;
• in response to the watermark appearing in a certain rectangular image region of the at least one rectangular image region, generate a stereoscopic format image according to the display frame and the certain rectangular image region comprises:
• dividing the display frame into the certain rectangular image region with the watermark and a two-dimensional background image block which is non-overlapped with the certain rectangular image region, wherein the certain rectangular image region comprises the streaming image conforming to a stereoscopic image format, and the streaming image comprises a first perspective image and a second perspective image;
• combining the first perspective image of the streaming image in the certain rectangular image region with the two-dimensional background image block as a first perspective image of the stereoscopic format image;
• and
• combining the second perspective image of the streaming image in the certain rectangular image region with the two-dimensional background image block as a second perspective image of the stereoscopic format image;
• and
• control the stereoscopic display to operate in a stereoscopic display mode to display the stereoscopic format image, to present image content of the streaming image with stereoscopic visual effect.
