    • A contents filter based on similarity of content character and correlation of subject matter includes a filtering system and a disciplining system, and the contents filter isn't a filtering system used for a special subject matter but a general subject matter, the filtering contents can be obtained by leaning of the disciplining system, the filtering system and the disciplining system are installed of physical separation, the filtering system communicates with the disciplining system through the data interface, the filtering system can be installed in the input device of network information. To achieve the different filtering effect the different filtering character obtained by the disciplining system are set to the filtering system located in the different input device of network information. The present invention implements filtering through analyzing and determining text contents, and offers an intelligent and effective service of contents safety for user. The use of the filter is in great agility. Furthermore the filter can identify the contents character to be filtered according to the character with disciplined class provided by user. The processing speed is fast and the filter can be conveniently installed.

    • In a daytime and nighttime image recognizing method and apparatus, the method comprises predefining an air region and a terrestrial region for each image captured by a camera apparatus; inputting an image captured by the camera apparatus; calculating a lightness value histogram for the air region of the input image; and determining a lighting condition of a photo environment of the camera apparatus based on the lightness value histogram for the air region of the input image. The daytime and nighttime image recognizing method and apparatus are able to correctly recognize the lighting condition of the environment even if the air region in an image is obstructed by a background or there are no lane lines in an image. Moreover, when an erroneous recognition occurs for an individual image, the interference caused by the erroneous recognition can be precluded efficiently.
