Benefits of technology

The present invention is a method for displaying images that adjusts the speed of each image based on its time length. This allows for efficient computation and distinguishes important images from unimportant ones. The method automatically adjusts the speed of each image based on its relationship to the next image, so as to provide a better user experience. Overall, the invention improves the efficiency and user-friendliness of image display methods.

Problems solved by technology

The image recording apparatus can store the monitoring video more than ten hours, and the burglary may spend few minutes breaking into the factory.
Thus, a method of rapidly replaying the monitoring video for increasing the searching efficacy is an important issue in the image identification industry.
The conventional video rapidly replaying method cannot provide preferred computation efficiency due to huge data computation.
The second conventional video rapidly replaying method may have the computation efficiency better than ones of the first conventional video rapidly replaying method; however, both the conventional video rapidly replaying methods adjust the monitoring video via the single speed, and cannot adjust several parts of the monitoring video via respective speeds.

Abstract

An image displaying method capable of automatically adjusting a displaying speed according to content of the image is applied to an image displaying apparatus. The image displaying method includes acquiring video data containing a first group of images and a second group of images, acquiring a first time difference between a first beginning image frame of the first group of images and a second beginning image frame of the second group of images, comparing the first time difference with a predetermined threshold value, and adjusting the displaying speed of the first group of images in accordance with a comparison result. Each group of images is consisted of a beginning image frame and at least one non-beginning image frame.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to an image displaying apparatus and an image displaying method, and more particularly, to an image displaying apparatus and an image displaying method capable of automatically adjusting a displaying speed according to content of video data.2. Description of the Prior Art[0002]An image recording apparatus usually stores a long-term monitoring video, and the monitoring video is replayed when something worse happened for finding out information in detail. To give an example, as a burglary happened in the factory, all the monitoring video has to be replayed to search a burglar because nobody knows what time the burglar breaks into the factory. The image recording apparatus can store the monitoring video more than ten hours, and the burglary may spend few minutes breaking into the factory. Thus, a method of rapidly replaying the monitoring video for increasing the searching efficacy is an important i...
