PROBLEM TO BE SOLVED: To provide a dark space exposure compensation method for simulating a high dynamic range by a single image and an image processor employing the same. SOLUTION: The dark space exposure compensation method for simulating a high dynamic range by the single image includes steps of: acquiring images P1 and P2 through clear space image enhancement processing and saturation contrast image enhancement processing; carrying out the image processing for determining whether or not there are clear and dark areas by selecting either of the images P1 and P2; acquiring a weighting reference image P3 by fuzzy image processing; carrying out mixed weighting calculation for pixels corresponding to a point by a point image P1 and those corresponding to the image P2 by the weighting value of each pixel of a weighting reference image P3; and acquiring an image P4 mixed by the images P1 and P2. This results in improving an image whose dark space becomes extremely dark by the excessive inequality of an exposure value in the image by using the single image. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a method and device for maintaining an image background by using multiple Gaussian distribution models. SOLUTION: The device for maintaining an image background by using the multiple Gaussian distribution models includes a capture module, a calculation module, a storage module, and a learning module. The capture module captures an image screen containing multiple pixels, is used for obtaining background information and consecutive image screens, and obtains multiple pieces of image information. The calculation module is used for establishing a main Gaussian distribution model and multiple sub Gaussian distribution models. The storage module stores the main Gaussian distribution model and sub Gaussian distribution models that are established by the calculation module. The learning module is used for comparing two of the sub Gaussian distribution models. When it is decided that all of the corresponding image information of the sub Gaussian distribution models belong to the background information, the learning of the main Gaussian distribution model is updated by the sub Gaussian distribution models. When at least one piece of the image information corresponding to the sub Gaussian distribution models is not background information, the learning of the main Gaussian distribution model is not updated.

PROBLEM TO BE SOLVED: To provide a computer system with power supply control and a power supply control method. SOLUTION: The computer system includes at least a first storage unit and a second storage unit, the first storage unit storing a system program that the computer system requires during basic operations. A switch is disposed on a power supply path between a power supply module and the second storage unit. The power supply module supplies via the switch the power required to operate the second storage unit. When the second storage unit is at idle, the power supply to the second storage unit is shut off by means of the switch to effectively reduce the power consumption of the computer system.
