A face detection device and method are provided. The face detection device receives captured images from a camera, and extracts vital information from a face region included in the captured images. The face detection device determines, based on the vital information, whether or not a face included in the face region is in a living state, and collates a feature quantity of the face included in the face region with information of a face which is previously registered. The face detection device selects, according to a user input, whether or not to perform at least one or both of a process for the determining, and a process for the collating.

A pulse can be stably estimated based on an image data suitable for extracting a pulse signal. A pulse estimation device includes image input portion () to which time-sequential captured images including at least a portion of subject H as an object are input from camera (); region extractor () that extracts a skin-color region from each of the captured images; zoom commander () that transmits a zoom command to camera () that has imaged the captured images or a user of camera () in order to adjust a size of the skin-color region; and pulse estimator () that estimates a pulse of subject H based on the skin-color region of the captured images obtained by imaging with camera (), after the zoom command is transmitted.

Face detection device that detects a face from an image including a person. The device includes a processor and a memory including instructions that, when executed by the processor, cause the processor to perform operations including: receiving captured images by a camera, detecting one face region or more in the captured images, extracting vital information which includes an index indicating a living state of a face imaged in the face region, based on image data regarding the detected face region; and determining whether or not the face in the face region is in a living state, based on the vital information. The face region detector recognizes a face region corresponding to the face which is determined to be in the living state by the vitality determiner among the one face region or more, as a face region based on a living body.

A biological information processing device includes an image input unit that inputs image data, a selection unit, an estimation unit, a detection unit, and an output unit. The selection unit selects image ranges of processing targets from the input image data. The estimation unit estimates pulse rates of the processing targets corresponding to the image ranges on the basis of image data of the selected image ranges of the processing targets. The detection unit performs relative comparison between the estimated pulse rates of the processing targets and thus detects a target which will possibly be abnormal or a target requiring special attention. The output unit outputs information regarding the detected target which will possibly be abnormal or the detected target requiring special attention.

A drowsiness estimation device comprises an imaging unit, a regional temperature calculation unit, and a weighted subtraction unit. The imaging unitobtains visible spectrum image data in a visible spectrum capture mode and obtains infra-red image data indicating a surface body temperature distribution for a subject's body in an infra-red capture mode. The regional temperature calculation unitdetects a temperature of an ocular center region within the surface body temperature distribution indicated by the infra-red image data. The weighted subtraction unitapplies a correction to a temperature parameter for drowsiness estimation, based on the detected ocular center region temperature. A drowsiness estimation for the user is then performed according to the corrected parameter.

An information-processing apparatus comprises a motion-detecting unit, a motion-compensating unit, a DCT/IDCT unit, a Q/IQ unit, a VLC unit, a VLD unit, and a DSP unit, as a plurality of units. A mode-controlling unit can utilize at least two modes of used of the information-processing apparatus. One mode is a 'process mode ' where the processing of moving picture are performed, and another mode is a 'memory mode' where all internal memories of the plurality of processing units are logically combined to be directly accessible from the outside as one memory via an interface unit.

Information-processing apparatus and electronic equipment using thereof

An image processing unit decodes coded data that have been coded and synthesizes the decoded moving image with graphics data. In a case where only graphics data are to be displayed, a bypass unit outputs the graphics data to a display device without use of an image processing unit. A control unit performs control of the supplying of a power supply voltage and a clock to a region containing the image processing unit and performs control of the bypass unit. If processing at the image processing unit is unnecessary, the supply of a power supply voltage or the supply of a clock to the region containing the image processing unit is stopped so as to stop the region and enable reduction of wasteful power consumption.

Data processing system for reducing wasteful power consumption

The present invention provides an image output device which can periodically update display of image data as well as update the display images immediately and with minimum data transfer. A data transfer request control circuit including a frame rate register for deciding a data transfer request issue cycle and a data transfer request issuing unit is provided in a video processing unit of the image output device. When an update flag is set in the frame rate register , the data transfer request is issued in the next transfer section, regardless of the periodic transfer cycle, and the image data stored in the frame memory are update.

Processor and image processing device

For every data, the number of data matches that occurred consecutively is written to a memory together with nonmatching data, and data from the memory is read out to continuously perform subsequent data processing and detect, at the same time, the last data written to the memory. To achieve this, a desired value is set in a data register, and a comparison instruction is issued by which the value set in the register is compared with a value set in a second register, and the number of matches that occurred consecutively is output together with nonmatching data; upon the output of a retrieval counter reaching a predetermined value, the comparison instruction is terminated, whereupon the number of consecutive matches, the nonmatching data, and an end flag signal are written to the memory at the same address.

Arithmetic unit and data processing unit

A bus switch is connected among an input buffer memory, a data memory, and an encoding unit, to select between a first bus connection of the input buffer memory and the data memory and a second bus connection of the data memory and the encoding unit. A data transfer control unit controls the bus switch to select the first bus connection in response to a data request signal from the encoding unit, controls the process of reading from the input buffer memory and the process of writing into the data memory, controls the bus switch to select the second bus connection upon completion of the transfer of one unit of image data, and sends a transfer completion signal in order of causing the encoding unit to start performing encoding processing. This makes it possible to transfer image data from the input buffer memory to the data memory at high speed.
