An illuminating module includes an illuminating device and an electrical connector. The illuminating device includes a first conductive contact and a second conductive contact. The electrical connector includes an external plug, a first internal conductive terminal and a second internal conductive terminal. The first internal conductive terminal electrically connects the external plug and the first conductive contact. The second internal conductive terminal electrically connects the external plug and the second conductive contact. The connection manner of the first internal conductive terminal and the first conductive contact belongs to fool-proof connection. The connection manner of the second internal conductive terminal and the second conductive contact belongs to fool-proof connection. The misconnection between the first and the second internal conductive terminals of the electrical connector and the first and the second conductive contacts of the illuminating device is prevented by means of the design of the illuminating module.

Method disclosed in the present invention is proposed to detect and eliminate flash scene in digital video. Particularly, averaging shot distribution of digital video is employed as knowledge to develop the algorithm of the present invention, and which is incorporated and used to identify three general types of shot distribution for flash scene event. In the present invention, the luminance difference between two consecutive frames is instead of actually analyzing the visual content so as to reduce the computational complexity. As a result, positions of flash frames can be exactly detected from the video signal for many applications. The method comprises the steps: frames are extracted from a video sequence inputted. A luminance difference by two adjoining frames is calculated. Then a histogram is made to record the differences, and a threshold is determined accordingly. Then the flash scene is detected and categorized into three types, and finally being eliminated.

A logo processing method includes: within a plurality of video frames sequentially received from a video source, comparing a base frame with at least a portion of the other video frames to generate a mask having at least one candidate region probably corresponding to at least one logo; performing post processing on the mask to correct the candidate region(s); and selecting at least one of the candidate region(s) as logo region(s) for indicating the logo(s).
摘要:
Simple, computational efficient, and robust audio features are applied in a uniform program indexing method for picking up video segments relating to highlight plays in a recorded program worthy of being reviewed. By focusing on certain frequencies in an audio sequence of the program, a computational complexity of the uniform program indexing method is significantly decreased. With the aid of MFCC coefficients and a DFBE coefficient generated from the MFCC coefficients, audio patterns may be utilized for differentiating exciting events in the program from other unnecessary information. Scores corresponding to various audio segments are regarded as standards for picking up video segments in the program worthy of being chosen in a recorded highlight collection. Some low-level-feature parameters, some video segments having highlight-related visual characteristics, and a re-ranking procedure are utilized for enhancing precision of the scores for providing video segments worthy of being reviewed.
