Embodiment Construction

[0020] The device and method for converting 2D to 3D images proposed by the present invention can achieve the effect of converting 2D images into 3D images without additional hole filling processing by using a simple depth image based rendering method.

[0021] Please refer to figure 2 , which shows a block diagram of a 2D-to-3D image conversion device according to an embodiment. The 2D-to-3D image conversion device 200 includes a data queue 210 , a conversion unit 220 and an offset calculation unit 230 . The data queue 210 receives and temporarily stores an input data value data_in corresponding to a current pixel. The conversion unit 220 outputs a current offset table corresponding to the current depth parameter according to a current depth parameter depth_ref corresponding to the current pixel. In practice, the conversion unit 220 can be designed as an offset look-up table (Offset LUT) for obtaining the current offset table according to the current depth parameter depth_...

Abstract

The invention relates to a 2D (two-dimensional)-3D (three-dimensional) image conversion device and method thereof. The device comprises a data queue, a conversion unit and an offset calculation unit, wherein the data queue is used for receiving and temporarily storing an input data value corresponding to a current pixel. The conversion unit is used for outputting a current offset table corresponding to a current depth parameter according to the current depth parameter corresponding to the current pixel, and the current offset table comprises (m+1) reference offset values corresponding to the current pixel and the adjacent m pixels. The offset calculation unit is used for selecting one reference offset value from a plurality of reference offset values corresponding to the current pixel in the current offset table and a plurality of prior offset tables as a data offset value corresponding to the current pixel. The data queue is used for selecting and outputting an output data value corresponding to the current pixel according to the integer part of the data offset value and an input data value.

Description

technical field [0001] The present invention relates to a 2D to 3D image conversion device and method. Background technique [0002] With the vigorous development of modern science and technology, human beings begin to pursue more real visual enjoyment than 2D image devices, so the related technologies of 3D stereoscopic images are becoming more and more mature in recent years. In order to form a 3D stereoscopic image with a common 2D image device, the 2D image must first be processed with the corresponding depth table to draw a double image corresponding to the 3D glasses, and then the 3D effect can be achieved by viewing with the above glasses. However, in the process of performing image warping (image warping) on ​​a 2D image with a corresponding depth table, the problem of missing data often occurs. [0003] Please refer to figure 1 , which is a schematic diagram of a known 2D-to-3D image conversion process. exist figure 1 In , the pixels undergo image warping accord...
