Problems solved by technology

[0005] Generally speaking, the stereo matching operation needs to obtain the left-eye image and the right-eye image from a memory device (for example, dynamic random access memory (DRAM)) at the same time, which consumes a lot of memory bandwidth. (memory bandwidth), in addition, the stereo matching operation needs to perform pixel-based or block-based matching, resulting in higher hardware cost and computational complexity

Embodiment Construction

[0020] Certain terms are used in the claims and description to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The claims and description do not use the difference in names as the way to distinguish components, but use the difference in function of the components as the criterion for distinguishing. The "comprising" mentioned in the claims and the specification is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. .

Abstract

A depth information generator includes a receiving circuit and a depth information generating block having a first depth information generating circuit included therein. The receiving circuit is arranged for receiving a multi-view video stream which transmits a plurality of images respectively corresponding to different views. The first depth information generating circuit is coupled to the receiving circuit, and arranged for generating a first depth information output by only processing part of the received images. In addition, a depth information generating method includes following steps: receiving a multi-view video stream which transmits a plurality of images respectively corresponding to different views; and generating a first depth information output by only processing part of the received images.

Description

technical field [0001] The present invention relates to generating depth information, in particular to a depth information generator that generates depth information output by only processing a part of received images with different viewing angles, and related depth information generation method and its depth Adjustment device. Background technique [0002] With the development of technology, what users pursue is stereo / three-dimensional and more realistic image display, instead of high-quality images. There are two technologies for displaying stereoscopic images, one is to use a video output device with glasses (such as anaglyph glasses, polarization glasses and shutter glasses), and The other is to directly use the video output device without any glasses. Regardless of the technology used, the main principle of stereoscopic image display is to make the left eye and right eye see different images. Therefore, the human brain will regard the different images seen by the two...
