  • Publication number: 20210089199
    Abstract: An interactive stereoscopic display and an interactive sensing method for the same are provided. In the method, a gesture sensor senses a hand gesture over a stereoscopic image displayed on a stereoscopic display. The gesture is such as moving, rotating or zooming actions. The gesture is referred to, to obtain stereo coordinate variations that are used to determine an interactive instruction. Next, the stereoscopic display or a stereoscopic image server generates a new stereoscopic image data by comparing image coordinate data of the stereoscopic image with a previous state of image coordinate data according to the interactive instruction. The stereoscopic image data describes color and three-dimensional information of the stereoscopic image. Therefore, the stereoscopic display displays a new stereoscopic image using the new stereoscopic image data. The method achieves an interactive effect with the stereoscopic image using the gesture.

  • Publication number: 20210067760
    Abstract: A stereoscopic display method and a system for displaying an online object are provided. The system provides a stereoscopic image server and a user-end stereoscopic image display. When a user browses a content website, the website provides a flat image to a user device, and a content server also generates a request for displaying an object. The stereoscopic image server generates a stereoscopic image data corresponding to the object according to the request. The stereoscopic image data can be obtained by querying an image database, or by calculation using a stereoscopic image resource file. The stereoscopic image data is provided for the stereoscopic image display to display a stereoscopic image. Alternatively, the stereoscopic image data can be generated by the user-end stereoscopic image display when it receives the stereoscopic image resource file from the server.

  • Patent number: 10473945
    Abstract: The disclosure is related to a method for tuning a three-dimensional image, and a display apparatus thereof. In the method, an integral image composed of multiple element images and used to reproduce a three-dimensional image is obtained. The pixel values of every element image are extracted. Depending on hardware configuration, a certain range of the pixels within one-dimensional pixels of the element image are selected. The pixel values of the selected pixels are filled in the zones divided from the one-dimensional pixels in an ascending order or a descending order, and/or with continuously-duplicate values according to pixel numbers of the selected pixels. A new element image is therefore formed. By repeating these steps, a new integral image can be created. This new integral image effectively reduces the difference between the image regions and won't make a viewer see the uncomfortable three-dimensional image due to the excessively large difference.
