Stereoscopic image forming method and relevant display module

Abstract

The invention relates to an image forming method. The method comprises the following steps of: inputting a color image; converting the color image into a first gray scale image; reducing the first brightness range of the first gray scale image into a second brightness range; generating a first gray scale gradient image corresponding to the space distribution of the first gray scale image according to the first brightness range and the second brightness range; superimposing the first gray scale image with the second brightness range and the gray scale gradient image to generate a second gray scale image; generating a translation image according to the second gray scale image and the color image; and forming a stereoscopic image according to the color image and the translation image.

Description

technical field [0001] The present invention relates to an image forming method and its related display module, especially a method for forming a three-dimensional image and its related display module. Background technique [0002] Generally speaking, the working principle of the stereoscopic image is to transmit the image seen by the left eye and the image seen by the right eye to the left eye and the right eye respectively. The received images are superimposed in the mind of the user into a three-dimensional image with depth of field and layering. At present, the common stereoscopic image generation methods used to allow the left and right eyes to see images with different parallax include polarizing glasses (Polarizing glasses), shutter glasses (Shutter Glasses), red-green (blue) stereoscopic display glasses (anaglyph) and glasses-free stereoscopic display glasses. display etc. [0003] But no matter what kind of stereoscopic image generation method is used to present, ...

[0003] But no matter what kind of stereoscopic image generation method is used to present, the method of generating different information for the left and right eyes is similar. Generally speaking, the image signal itself must first have different images for the left and right eyes. One of the common The method is to use the depth map corresponding to the color image to calculate the relative translation of each pixel on the color image, and then generate multiple sets of color images corresponding to the left and right eyes with different translations. However, the current method used to generate the corresponding depth map The generation method often has the problem of complex calculation or wrong depth image acquisition. For example, in US20060232666, it is disclosed to perform edge detection of objects in the image based on the motion vector, brightness or color value of the previous and current images. Then use the edge detection results to generate a depth map. However, this method often has the problem of contour extraction errors when detecting objects, resulting in a distorted depth map and affecting the quality of stereoscopic images.

In addition, another common way is to use related drawing software (such as Photoshop) to manually create depth maps. Although the depth maps drawn in this way have high accuracy, the process of making depth maps is often difficult. time consuming
