[0032] figure 2 is a schematic diagram illustrating an image processing device according to the first embodiment.

[0033] Please refer to figure 2 , the image processing device 200 includes a processor 210 and a memory 220 . For example, the image processing device 200 can be implemented as a computer, a server, a distributed system, a TV, a smart phone, a tablet computer, or any other embedded system.

[0034] The processor 210 is used to execute one or more instructions. For example, the processor 210 may be a central processing unit (Central Processing Unit, CPU), a microprocessor (Microprocessor) or a digital signal processor (Digital Signal Processor, DSP).

[0035] The memory 220 is used for storing data and instructions. For example, the memory 220 can be random access memory (random access memory), flash memory (Flash) or other memory.

[0036] In this embodiment, the memory 220 stores a plurality of instructions, and the processor 210 executes these instructio...

[0057] The second embodiment is similar to the first embodiment, and only the differences are described here. In the first embodiment, the processor 210 calculates the displacement of each first layer (or second layer) in the x direction without considering the rotation. However, in the second embodiment, the processor 210 also considers the rotation and calculates the displacement in the y direction.

[0058] Figure 4 It is a top view illustrating rotating the first image and the second image according to the second embodiment. Figure 5 is a front view illustrating rotating the first image and the second image according to the second embodiment.

[0059] Please refer to Figure 4 and Figure 5, the first image 231 includes an axis 401 , and the processor 210 rotates the first image 231 by an angle (−θ) according to the axis 401 to generate an adjusted first image 231 - 1 . The second image 232 includes an axis 402 , and the processor rotates the second image 232 by an ...

Abstract

A stereoscopic image adjustment method and image processing device. The method includes: obtaining a difference map between the first image and the second image; dividing the difference map into multiple layers, which correspond to multiple first layers of the first image and multiple third layers of the second image. Two layers; the first cost is generated based on the displacement of the pixels of the i-th first layer and the i-th second layer; the first cost is generated based on the displacement of the pixels of the i-th first layer and the j-th first layer. The difference between the pixels of the i-th second layer and the j-th second layer generates a second cost; at least perform the optimization algorithm based on the first cost and the second cost to obtain all displacements; and adjust the position of the corresponding pixels based on these displacements. In this way, viewers can have a better viewing experience.

Description

technical field [0001] The present invention relates to a stereoscopic image adjustment method, and in particular to an adjustment method using an optimization algorithm and an image processing device. Background technique [0002] Stereo images are composed of two or more images from different viewing angles. A stereoscopic image display allows the left eye to see an image from one perspective and the right eye to see an image from another perspective, whereby the brain synthesizes a three-dimensional image. However, images from different perspectives are displayed on a flat screen, so the human eye focuses on the screen, and the brain synthesizes a three-dimensional image in front of or behind the screen. Such a situation may cause discomfort or dizziness to the viewer. Generally speaking, when the synthesized image is too far away from the screen, the viewer will experience the above discomfort. [0003] figure 1 is a schematic diagram of shooting stereo images. [0...
