In order to solve a problem of an accumulation on the transmission side, a delay on the reception side, and the like at the time of transmission in a communication system such as a wireless LAN system, each communication station in a network transmits a beacon in which information with respect to the network is written and sets a state in which a reception operation is performed during periods of time before and after the transmission of the beacon signal when performing access control not to make communication timing of a packet collide with that of another station by detecting a signal transmitted from another station. With performing such processing, a system can be formed based on minimum level of transmission and reception operation when transmission and reception data does not exist in each communication station in the network, and also a data transfer can be performed with latency as small as possible in a minimum necessary level of transmission and reception operation by making a transition of a transmission and reception state in accordance with a fluctuating volume of transmission and reception data.

An image capturing apparatus including an image input unit configured to input an image to be captured; a face detecting unit configured to detect a face of at least one photographic subject included in the input image; a face-attribute detecting unit configured to detect attribute information of the detected face; a degree-of-friendliness computing unit configured to evaluate a degree of friendliness between a plurality of photographic subjects based on a correlation between items of attribute information of detected faces of the plurality of photographic subjects, the items of attribute information being detected by the face-attribute detecting unit, and outputting an evaluation value Hlove representing the degree of friendliness; and an image-capturing determining unit configured to determine a timing to capture the input image based on the evaluation value Hlove.

The invention relates to a statistics downscaling method based on the SVM algorithm. The statistics downscaling method includes the following steps that firstly, large-scale weather forecast factors are screened and representative factors are obtained; secondly, a wet day state and a dry day state of existing day-by-day rainfall data are judged, the data are processed, an SVM is used for constructing a classification relation between a raining state and the corresponding forecast factor at first, and a statistics relation on raining in wet days and meteorological factors is constructed; thirdly, an existing classification relation is used for classifying rainfall states in the incoming days through the weather forecast factors; fourthly, an existing statistics relation is used for fitting rainfall data on incoming rainy days through the weather forecast factors; fifthly, the data are restored and a forecast rainfall sequence is obtained. The statistics downscaling method based on the SVM algorithm has the advantages that effects of the statistics downscaling method are superior to those of a traditional statistics downscaling method and advantages are prominent when downsizing is carried out on the temperature; the operation volume is little, the method is convenient to use and specialized in processing a large volume of data of multiple batches, rainy days and dry days can be distinguished and higher precision is obtained; random values are added into rainfall and the fitting precision of rainstorms is higher.

Provided are a channel management method and a channel selection method for a wireless node in a wireless ad-hoc network. The channel management method includes the steps of: (a) when a current mode is a first mode, performing channel selection using a method for evenly distributing a channel within an interference range; and (b) when the current mode is a second mode, performing channel selection based on a channel switching probability. According to the method, by preventing a channel change from being continuously repeated in a wireless ad-hoc network using multi-channel multi-interface, it is possible to prevent data transmission delay and network performance deterioration.

To display images by suitably superimposing a graphics image on a high-dynamic-range image in an easily visible manner.A dynamic range converter (311) converts a SDR graphics image to an HDR graphics image based on metadata. An image combiner (312) combines the graphics image of which the dynamic range has been converted to HDR with HDR content. A dynamic range converter (313) performs display mapping on the HDR content combined with the graphics image based on metadata.

A system and method that utilizes common symbols for marking the tones of alphabet letters of different languages. The marking system and method employs the symbols from the standard English typing keyboard to denote tones. There are seven phonetic tone marks. Each mark represents a unique tone. The system can be applied to any alphabetic writing letters of different languages to denote specific language tones. The method makes it possible for alphabetic writing of any kind of language and for people to effectively capture the tones of words in different languages.
