摘要:
A power management system for an integrated circuit has a signal line, a management data generating unit connected to the signal line, and a plurality of management data using units each connected to the signal line. The management data generating unit outputs, to the signal line, power management data for managing power consumption in each of the management data using units, the power management data corresponding to the state of the management data generating unit. Each of the management data using units reads the power management data for common use from the signal line and controls power consumed by the management data using unit based on the power management data.
摘要:
A total specification is divided into a hardware specification and a software specification. With respect to the hardware specification, a first hardware description is described. With respect to the software specification, an object program is generated, which is converted into a second hardware description. The first and second hardware descriptions are logically synthesized into a net list, which includes a part that fulfills the software specification. Since the object program is converted into the second hardware description, which is logically synthesized, the redundancy of the program can be removed and cost for manufacturing hardware can be reduced.

In a data-sending device, a data generation section provides input data itself or a bit-inverted version of the input data as intermediate data and generates an inversion signal that indicates whether or not the intermediate data is the bit-inverted version of the input data. An encrypting section generates scrambled data by inserting the inversion signal in the intermediate data at a bit position. A data-receiving device removes the inversion signal from the scrambled data, and restores the input data based on the inversion signal.

A liquid crystal display device for carrying out a 3D display by a frame sequential method as well as a 2D display includes: a digital γ correction section for changing an input gray level to a gamma characteristic corresponding to either the 2D display or the 3D display in accordance with a preset analog gamma value; an overdrive circuit for finding, in accordance with a parameter set according to the gamma characteristic thus corrected by the digital γ correction section, an overdrive value corresponding to the input gray level; and an analog γ correction section for finding a voltage value to be applied to liquid crystal by correcting the overdrive value found by the overdrive circuit. In the digital γ correction section, an analog gamma value for the 3D display is set to be larger than an analog gamma value for the 2D display.

An image judgment device stores element characteristic information for each element of a characteristic part of a sample object and first and second positional information defining a position of each element, selects the first or the second positional information, and acquires image characteristic information for a partial image in an image frame considered as an element specified by the first positional information based on a first axis. The image judgment device also extracts image characteristic information for a partial image in an image frame considered as an element specified by the second positional information based on a second axis (which is acquired by rotating the first axis), specifies element characteristic information for an element corresponding to a position of the partial image, and judges whether the characteristic part appears in the image frame with use of the specified element characteristic information and the extracted image characteristic information.

An object detection device is provided with a plurality of processor units each detecting an object included in an image. The object detection device generates divided images by dividing the image, taking into consideration both the processing load for detection of an object by each processor element and the transfer load for transfer of the divided images to the processor elements. Independently of each other, the processor elements detect an object in each of the divided images.

A face detection apparatus of the present invention includes a face detection apparatus for detecting a face contained in an input image, including: a face detection section for detecting a face contained in the input image, based on a predetermined frame rate and face detection throughput per frame; and an accuracy changing section for changing, when no face is detected by the face detection section, the accuracy in detecting a face by the face detection section by reducing the frame rate.

In one embodiment of the present invention, a frame interpolation process circuit performs an interpolation process on a video signal in units of frames. A time-division gradation process circuit performs gradation level conversion for distributing brightness for one frame cycle to two sub-frame cycles, i.e., first and second sub-frame cycles. A gradation level change detection circuit detects whether a gradation level of each pixel has changed between consecutive sub-frames. For any pixel having its gradation level changed, an overshoot process circuit outputs, instead of an output signal of the time-division gradation process circuit, a video signal obtained by subjecting an output signal of the frame interpolation process circuit to gradation level conversion for emphasizing a temporal change of the signal. A predetermined-times higher speed process circuit may be added to this circuit configuration, or may be substituted for the frame interpolation process circuit. This makes it possible to improve moving image display performance, while making up for a lack of response speed of display elements.

An liquid crystal display (LCD) device uses a method for displaying halftone without causing luminance differences among pixels when an FRC technique is used, and without causing stripe-shaped luminance variations when a flicker component is eliminated spatially. The LCD device includes a data splitter, a pixel location detecting circuit, a frame number determining circuit, an applied timing memory circuit, an applied voltage determining circuit, a summation process circuit, and a timing adjusting circuit. The LCD device determines driving voltages such that for each of a high voltage or a low voltage during these 2N frames, the number of applying positive voltages is the same as the number of applying negative voltages where a unit period is 2N frames for multi-gray-level display of (1+N) levels. The LCD device can improve image quality since the average luminance of each pixel is made uniform.
