Abstract
A method of processing a 3D image data includes calculating shift values of gray-scales for a reference view using a 3D effect selection signal having a selection depth value of the 3D image inputted by a user. Shift values of the gray-scales respectively corresponding to a plurality of views are calculated using the shift values of the gray-scales for the reference view. The shift values of the gray-scales respectively corresponding to the plurality of views are applied to a source image signal to generate a plurality of image frames.
Claims18
A method of processing a three-dimensional (“3D”) image, the method comprising:
- receiving a source image;
- receiving a 3D image depth selection value from a user;
- calculating shift values for shifting the received source image based on the received 3D image depth selection value;
- and
- applying the calculated shift values to the source image signal to generate a 3D depth-adjusted image,
- wherein calculating the shift values of the gray-scales for the reference view comprises:
- calculating a maximum shift value to a maximum gray-scale for the reference view based on the received 3D image depth selection value;
- calculating a minimum shift value to a minimum gray-scale for the reference view using the calculated maximum shift value;
- and
- calculating middle shift values to middle gray-scales for the reference view using the calculated maximum and minimum shift values and the middle gray-scales between the maximum gray-scale and the minimum gray-scale for the reference view,
- wherein the steps of receiving the source image, receiving the 3D image depth selection value, calculating the shift value, and applying the calculated shift value are performed using one or more circuits.
A display apparatus comprising:
- a display panel displaying a 3D image;
- a 3D effect adjusting circuit calculating shift values of gray-scales for a reference view of the 3D image using a 3D effect selection signal having a 3D image depth selection value inputted by a user and calculating shift values of the gray-scales respectively corresponding to a plurality of views of the 3D image using the shift values of the gray-scales for the reference view;
- a multi-view image generating circuit applying the shift values of the gray-scales respectively corresponding to the plurality of views to a source image signal to generate a plurality of image frames;
- and
- a panel driving circuit converting an image signal of the image frames into an analogue-type data signal and providing the analogue-type data signal to the display panel,
- wherein the 3D effect adjusting circuit comprises:
- a max/min calculating circuit calculating a maximum shift value of a maximum gray-scale for the reference view based on the 3D image depth selection value and calculating a minimum shift value of a minimum gray-scale for the reference view using the maximum shift value;
- a middle calculating circuit calculating middle shift values of middle gray-scales for the reference view using the maximum and minimum shift values, and the middle gray-scales between the maximum gray-scale and the minimum gray-scale for the reference view;
- and
- a multi-view image calculating circuit calculating shift values of the gray-scales respectively corresponding to a plurality of views using the shift values of the gray-scales for the reference view.
