20080209162PROCESSOR AND PROGRAM EXECUTION METHOD CAPABLE OF EFFICIENT PROGRAM EXECUTION - A processor for sequentially executing a plurality of programs using a plurality of register value groups stored in a memory that correspond one-to-one with the programs. The processor includes a plurality of register groups; a select/switch unit operable to select one of the plurality of register groups as an execution target register group on which a program execution is based, and to switch the selection target every time a first predetermined period elapses; a restoring unit operable to restore, every time the switching is performed, one of the register value groups into one of the register groups that is not selected as the execution target register group; a saving unit operable to save, prior to the restoring, register values in the register group targeted for restoring, by overwriting a register value group in the memory that corresponds to the register values; and a program execution unit operable to execute, every time the switching is performed, a program corresponding to a register value group in the execution target register group.08-28-2008

20090148034Mobile robot - There is disclosed a mobile robot including an image processor that generates recognition information regarding a target object included in a taken image, and a main controller integrally controlling the robot based on this recognition information. The image processor executes steps of: generating a low-resolution image and at least one high-resolution image whose resolution higher than that of the low-resolution image; generating first target object information regarding the target object from the low-resolution image; determining which high-resolution image should be processed if two or more high-resolution images are generated, and then defining a resolution process region in the low-resolution image; processing a region in the high-resolution region corresponding to the resolution process region in the low-resolution image, so as to generate second target object information in the high-resolution image; and determining whether or not the first and the second target object information are matched; and based on this determination, using at least either of the first and the second target object information, thereby to generate the recognition information.06-11-2009

20090059033Camera exposure controller - In an exposure controller of a camera mounted on a robot for taking an image utilizing incident light from external world in which an object such as a human being is present, a brightness histogram of the image is generated and exposure parameters are set based on the generated histogram. Then, it is determined whether the set exposure parameters are within a predetermined range and when they are out of the range and if a high-brightness imaging region is present in the image due to high-brightness incident light, it is again determined whether it is necessary to remove the high-brightness imaging region. When it is determined to be necessary, the high-brightness imaging region is extracted and is removed from the image, thereby enabling the camera to image the object with suitable brightness even when a bright light source such as the sun is within the camera angle of view.03-05-2009
