Claim:
1. A transparent display system, comprising: a transparent display unit positioned between at least one image acquiring unit and an external light source; a position determination unit for the image acquiring unit, configured to determine a position of the image acquiring unit and to output a position information about the image acquiring unit to a projective coordinate calculation unit; a position determination unit for the light source, configured to determine a position of the external light source and to output a position information about the external light source to the projective coordinate calculation unit; the projective coordinate calculation unit, configured to calculate coordinate distribution of a projective area based on the position information about the image acquiring unit and the position information about the external light source, and to output a coordinate distribution information corresponding to the coordinate distribution to a control unit, the projective area is a region in the transparent display unit the display state of which needs to be adjusted; the control unit configured to generate a display control signal based on the coordinate distribution information and to output the display control signal to the transparent display unit; wherein the transparent display unit displays based on the display control signal so as to adjust display states of the projective area in the transparent display unit, wherein the image acquiring unit is user's eyes, and the position determination unit for the image acquiring unit is configured to determine a position of user's eyes and to output information about the position of the user's eyes to the projective coordinate calculation u therein the position determination unit for the image acquiring unit is configured to obtain coordinates of the left and right eyes of the users; the position determination unit for the light source is configured to obtain coordinates of the most left end and the most right end of the external light source, the most left end and the most right end of the external light source are two intersection points at which a plane defined by the user's eyes and a center of the external light source intersects with a profile line of the external light source; and the projective coordinate calculation unit is configured to determine a coordination distribution of the projective area based on the coordinate of the intersection points at which a first connecting line and a second connecting line intersect with the transparent display unit, the first connecting line is a connecting line from the user's left eye to the most left end of the external light source, and the second connecting line is a connecting line from the user's right eye to the most right end of the external light source.
