The first color gamut conversion unit 102 limits, in a visually natural manner, an output signal to a signal within a range of the DCI color gamut through well-known color gamut conversion processing when there is a color region exceeding the DCI color gamut, the output signal being obtained through the imaging by the imaging unit 101 and represented by the primaries (R, G, and B) determined by a color filter of an image sensor of the camera. It is to be noted that a color gamut conversion technique may be any technique which can limit a color gamut such as gamut conversion processing (Non Patent Literature: “Fundamentals of Color Reproduction Engineering”, Corona Publishing Co., Ltd., pp. 178-180).

This provides a fast and very efficient way of studying references with little or no stress. User can select various soothing sounds to be played briefly before switching into another reference. Various keyboard key operations are used to switch between the key features of the search and references.

The invention discloses a method for determining a technological development vein diagram. The method comprises the steps that important patent literature is found in a background according to a specific index, and then co-occurrence analysis method selection is carried out; one of co-citation analysis, co-classification analysis and co-word analysis is selected; if a co-citation analysis method is selected, a technological development vein is analyzed according to a quoting relation and the time dimension; if co-classification analysis or co-word analysis is selected, the technological development vein is determined according to the technical relation correlation degree on the time relationship and the time dimension. The technological development vein diagram can reflect the research hotspot and the core technology in a certain technical field, the quoted development trend of the patented technology is accurately grasped, therefore, change information of the technology frontier can be effectively acquired, and important significance is achieved.

The invention relates to a patent map visualization method and system. The patent map visualization method comprises the steps that multi-dimensional text vectors corresponding to patent literatures in a patent literature data set are obtained; clustering analysis is conducted on the multi-dimensional text vectors corresponding to the patent literatures to obtain multiple clustering results; multiple patent literatures corresponding to the clustering results are mapped to a two-dimensional plane so as to perform dimension reduction processing, and patent literature data points are obtained; visualized calculation is conducted on the multiple patent literature data points to generate visualized data, and the visualized data is displayed on the two-dimensional plane in a three-dimensional image mode. By the adoption of the patent map visualization method and system, the operation amount in the patent map generating process can be simplified, accordingly the occupation to a CPU and a memory is decreased, and real-time patent map generation and display are achieved.
