Embodiment Construction

[0020] In order to speed up the calculation of image conversion, the present invention proposes an estimation method that does not need to perform a large number of division operations, and converts the triangles included in the plane image with larger areas. Since a large number of division operations are not required, a faster image conversion effect can be achieved within an acceptable range of visual effects.

[0021] The first embodiment of the present invention is as figure 2 As shown, it is an image conversion device, including a selection module 201 and a processing module 203, which can convert the original plane image into a three-dimensional effect image. The selection module 201 first selects a triangle with a larger area in the original plane image. The reason for choosing larger-sized triangles is that the present invention performs sum-difference and multiplication operations in an estimating manner instead of a large number of division operations, so larger-s...

Abstract

The invention relates to an image switching device, which comprises a selecting module and a processing module. The selecting module selects a triangle of which one of the transverse dimension and the longitudinal dimension exceeds the predetermined value in the primitive plane image. The processing module is used for calculating a first corresponding value in the straight line, after multiplying a first pixel coordinate value, the first corresponding value can be converted to the first corresponding pixel coordinate value of a three dimensional effect image, and is used for calculating a converted difference value according to the number of the pixel included in the straight line, and is used for performing the sum-and-difference operation to the first corresponding value and the arithmetic product of the square of the first corresponding value and the converted difference value, to obtain the next corresponding value.

Description

technical field [0001] The present invention relates to an image conversion device and method; in particular, to an image conversion device and method that utilizes sum, difference and multiplication operations to accelerate image conversion. Background technique [0002] Generally speaking, what is displayed on the monitor is a flat image. However, when displaying static or continuous images, in order to satisfy the visual viewing experience, the image processor will convert the original flat image into a stereoscopic image by applying perspective conversion. 3D effect image for the effect. [0003] Since the perspective method needs to undergo projection conversion to show the depth effect on the flat display, it is necessary to correct the image effect error caused by the non-linear operation of the projection conversion after the projection effect on the plane. Generally speaking, the standard conversion method Corrected for non-linear interpolation. The geometric proj...
