  • Publication number: 20120226890
    Abstract: The process speed and the power efficiency are improved while accomplishing downsizing by configuring an integrated hard-wired logic controller by a hard-wired logic, and a function modification is enabled by a patch circuit without re-designing of the integrated hard-wired logic controller itself by high-level synthesis even when the function modification becomes necessary because of a specification change and a false design after the production. The costs can be reduced by what corresponds to the unnecessity of re-designing. Therefore, an accelerator is provided which can improve the process speed and the power efficiency while accomplishing downsizing, and which can remarkably reduce the costs for the function modification after the production.

  • Patent number: 8134604
    Abstract: Movement of an imaging device is detected using a camera shake detection sensor or a motion vector obtained from an image signal, and camera shake correction is performed by shifting an extraction frame (valid photographing region) within a photographable maximum region based on the motion detection result. When movement of the imaging device is causing a face region located at the edge of the extraction frame to move towards out of the frame, it is determined that the movement is due to camera shake, and the extraction frame is moved so that the face region can stay within the frame. Meanwhile, when movement of the imaging device is causing the face region to move inward within the frame, it is determined that the movement is due to a pan or tilt operation, and position control is performed so that the deliberate movement is not inhibited.

  • Patent number: 8000558
    Abstract: Based on, for example, the image at the start of a movie, a thumbnail image is tentatively generated and is stored in a header file. If a predetermined triggering condition is fulfilled during movie shooting, a thumbnail image is generated from the frame image at the timing that the triggering condition is fulfilled, and the thumbnail image existing in the header file is replaced with the newly generated thumbnail image. The triggering condition is fulfilled, for example, if, after zooming-in, the angle of view has been kept fixed for a predetermined period or longer, or if the focus has been kept locked for a predetermined period.

  • Patent number: 7941776
    Abstract: A closed-loop IC design optimization process by automatically or manually creating design-specific cells with desired characteristics (e.g., performance, area, power, noise, etc.), which will be then implemented as a standard cell (also known hereafter as metacell), from a set of post-layout patterns. A post-layout pattern represents a part or whole of a standard cell and contains information regarding the pattern including, but not limited to, layout, timing, area, power and noise. As the metacells are created from post-layout patterns, the inaccuracies of prior dynamic library techniques are easily avoided. Such metacells, being design-specific, are optimized to satisfy the constraints imposed by the design context, thus bringing the powerful design-specific customization to standard cell-based design methodology.
