FIG. 7 is a diagram illustrating an image formed by a left eye image and a right eye image, and FIG. 8 is a diagram illustrating a depth of a 3D image according to an interval between a left eye image and a right eye image.
First, referring to FIG. 7, a plurality of images or a plurality of objects 615, 625, 635, and 645 are illustrated.
First, the first object 615 includes first left eye images 611 and L based on the first left eye image signal and first right eye images 613 and R based on the first right eye image signal. An interval between the first left eye image 611 and L and the first right eye image 613 and R is illustrated to be d1 on the display 180. At this time, the user recognizes that an image is formed at an intersection of an extension line connecting the left eye 601 and the first left eye image 611 and an extension line connecting the right eye 603 and the first right eye image 603. Accordingly, the user recognizes that the first object 615 is located behind the display 180.
Next, since the second object 625 includes the second left eye images 621 and L and the second right eye images 623 and R and overlaps each other, the second object 625 is displayed on the display 180. do. Accordingly, the user recognizes that the second object 625 is located on the display 180.
Next, the third object 635 and the fourth object 645 are the third left eye image 631 and L, the second right eye image 633 and R, and the fourth left eye image 641 and L and the fourth object, respectively. The right eye images 643 and R are included, and the intervals are d3 and d4, respectively.
According to the above-described method, the user recognizes that the third object 635 and the fourth object 645 are positioned at the positions where the images are formed, respectively, and in the drawing, each of them is located in front of the display 180.
At this time, it is recognized that the fourth object 645 is projected before the third object 635, that is, more protruded than the third object 635. This is because the interval between the fourth left eye image 641, L and the fourth right eye image 643, d4 is larger than the interval d3 between the third left eye image 631, L and the third right eye image 633, R. [
Meanwhile, in the exemplary embodiment of the present invention, the distance between the display 180 and the objects 615, 625, 635, and 645 recognized by the user is expressed as a depth. Accordingly, the depth when the user is recognized as if it is located behind the display 180 has a negative value (-), and the depth when the user is recognized as if it is located before the display 180. (depth) is assumed to have a negative value (+). That is, the greater the degree of protrusion in the direction of the user, the greater the size of the depth.
Referring to FIG. 8, the distance a between the left eye image 701 and the right eye image 702 of FIG. 8A is the distance between the left eye image 701 and the right eye image 702 shown in FIG. 8B. If (b) is smaller, it can be seen that the depth a 'of the 3D object of FIG. 8 (a) is smaller than the depth b' of the 3D object of FIG. 8 (b).
As such, when the 3D image is exemplified as the left eye image and the right eye image, a position recognized as image formation from the user's point of view varies depending on the distance between the left eye image and the right eye image. Therefore, by adjusting the display interval of the left eye image and the right eye image, it is possible to adjust the depth of the 3D image or 3D object composed of the left eye image and the right eye image.
