Embodiment Construction

[0030] Please refer to figure 1 , figure 1 It is a timing diagram of various operations during stereoscopic image playback. Such as figure 1 As shown, when performing stereoscopic image playback, an image output unit will issue a request command to obtain the information of the required left-eye image frame and right-eye image frame, which includes the steps: The left-eye image frame and the right-eye image frame are synchronized to determine the left-eye image frame and the right-eye image frame required by the image output unit. After the synchronization is completed, the synchronization completion notification and the determined left-eye image frame will be notified. The information of the image frame and the right-eye image frame is sent back to the image output unit. In general, synchronous operations need to be completed within a limited time Tth to avoid errors.

[0031] Please refer to figure 2 , figure 2 It is a schematic diagram of a stereoscopic image output...

Abstract

The invention provides a stereoscopic image outputting method which comprises the following steps: providing a requirement directive; outputting current image frame information from a storage unit to respond the requirement directive, and triggering the synchronous image processing to update the image frame information of the storage unit; outputting a group of stereoscopic images from a storage according to the image frame information.

Description

technical field [0001] The invention relates to a stereoscopic image output device, in particular to a stereoscopic image output device capable of outputting a synchronized stereoscopic image within a limited time and a related stereoscopic image output method. Background technique [0002] In the prior art, when performing stereoscopic video playback, an image output unit will send a request command to a control unit at regular intervals to obtain the information of the required left-eye image frame and right-eye image frame, and when the control unit After the unit receives the request command, it first performs a synchronization operation on the left-eye image frame and the right-eye image frame, and then transmits the synchronization result and related information of the left-eye image frame and the right-eye image frame to the image output unit. However, if the time for synchronizing the left-eye image frame and the right-eye image frame is too long, then this procedure...
