Transparent display system, parallax correction method and image outputting method

An image outputting method for a transparent display system, wherein a transparent display device is located between a background object and a user, and the image outputting method comprises:

• capturing an image comprising the transparent display device, the background object, and the user;
• obtaining an equivalent eye position, which is located between a right eye and a left eye of the user, of an ocular dominance of the user according to an intersection of a plurality of visual extension lines, where the visual extension lines extend from at least two display anchor points and at least two background object anchor points, wherein the display anchor points are located on the transparent display device, and the background object anchor points are located on the background object;
• obtaining a physical position of the background object on the image;
• obtaining a display position on the transparent display device according to at least a connection line between the equivalent eye position and the physical position;
• and
• displaying an image on the transparent display device according to the display position.

A transparent display system, comprising:

• a transparent display device located between a background object and a user and configured to display a gaze point;
• an image capturing device configured to capture an image comprising the transparent display device, the background object, and the user;
• a processing device connected to the image detection device, wherein the processing device comprises:
• an image analysis unit configured to detect at least two display anchor points and at least two corresponding background object anchor points on the image, wherein the display anchor points are located on the transparent display device, and the background object anchor points are located on the background object;
• and
• a space calculation unit configured to calculate a visual extension line extending from each of the display anchor points and each of the corresponding background object anchor points, and calculate an equivalent eye position, which is located between a right eye and a left eye of the user, of an ocular dominance of the user according to an intersection of the visual extension lines and the connection line between the two eyes;
• and
• a storage unit configured to record the equivalent eye position.
