摘要： A 2D to 3D image conversion apparatus includes a data queue, a conversion unit and an offset calculation unit. The data queue receives and temporarily stores an input data value corresponding to a current pixel. The conversion unit outputs a current offset table corresponding to a current depth parameter of the current pixel. The current offset table includes (m+1) reference offsets corresponding to the current pixel and neighboring m pixels. The offset calculation unit selects one of the reference offsets corresponding to the current pixel in the current offset table and multiple previous offset tables as a data offset corresponding to the current pixel. The data queue selects and outputs an output data value corresponding to the current pixel according to an integer part of the data offset and the input data value.

The determining unit determines a noise level of the present image from the first and second output values, and outputs a blended value. The output unit adds together weights of pixels at the same positions of the present and previous images according to the blended value to generate an output image. An image processing method is also disclosed.
