摘要:
A 3-dimensional image acquisition apparatus acquires images to be used for 3-dimensionally reconstructing an object by picking up the object by a camera twice or more in an image acquisition set including picking up at least once the object carrying a pattern projected onto it by a projection light source. The apparatus comprises a light projection information memory configured to store information on projection of light including information on the time for projecting light for the purpose of projecting the pattern in the image acquisition set, an image acquisition progress information memory configured to store information on the progress of image acquisition in the image acquisition set, and a controller configured to control the projection of light by the projection light source and the picking up by the camera on the basis of the stored information on projection of light and the stored information on the progress.

A movement detection device includes a self-sustaining movement detection unit which is attached to an operator's body and detects a movement or a posture of an attached part of the operator's body. An image pickup section picks up a projected image from an optical system which simultaneously inputs a peripheral image. An image conversion section converts an all azimuth image picked up by the image pickup section into a cylindrical panorama image. An image recognition section includes cylindrical panorama images at different times. A camera posture estimation section acquires movement information of the image pickup section based on a comparison result of the image recognition section. A space sensor posture estimation section acquires a position/posture of the attached part in a space based on information of the self-sustaining movement detection unit and the camera posture estimation section.

A communication device such as a portable video telephone capable of transmitting images as well as sound is capable of preventing the transmission of dark and featureless images resulting from the device being used in a dark location. When an image is to be transmitted, a device controller determines if the present ambient light level is too dark by measuring the light level of a light sensor. If the ambient light is inadequate, the controller generates a brightness warning on the device display, and stops image transmission.

A reference frame adapted to be fitted to a subject of medical treatment and provided with markers for determining the position or the orientation of the subject comprises fitting section for fitting the reference frame with the subject at least three spots (tops of the left and right ears and the nasal projection) along the undulations of the surface thereof and three or more than three markers detectable at least ether in an X-ray image or in an MRI image of the reference frame, the markers being to be arranged at predetermined positions not connectable by a straight line. A surgical operation navigating system determines the coordinates of the markers in a coordinate system defined for the image taken for the purpose of medical examination of the subject who is carrying the reference frame on the basis of the obtained image. Then the corresponding relationship is established between the coordinate system for the image for examination and the coordinate system for the real space containing the markers on the basis of the result of the operation of determining the coordinates of the markers in the coordinate system for the image for examination and the coordinates of the markers in the coordinate system for the real space.

A to-be-cleaned substrate is cleaned by use of an acid liquid agent in a cleaning cup, the remaining acid liquid agent is washed out by use of pure water, then an alkaline liquid agent is emitted to the surface of the to-be-cleaned substrate in the same cleaning cup to remove the acid liquid agent remaining on the to-be-cleaned substrate. A neutralization reaction between the acid and alkali is caused by emitting the alkaline liquid agent to the surface of the to-be-cleaned substrate so as to efficiently remove the acid liquid agent remaining on the surface of the to-be-cleaned substrate.

A cellular video telephone terminal is capable of switching its operation mode between a voice communication and a voice and image communication in response to a manual operation on a key. A control unit checks whether the key is operated to effect the voice and image communication. The control unit sets volumes of a speaker and a microphone to low levels in the voice communication mode. The control unit sets the volumes of the same to high levels in the voice and image communication mode to enable hand-free operation.

A bird's eye view commonly used in a flight simulation is applicable to an apparatus and method for navigating a vehicle running on a set route of travel to a set destination using a (color) display unit according to the present invention. The bird's eye view of a road map surrounding a present position of the vehicle has a viewing point placed at a predetermined position on an upper sky in a direction opposite to the set destination with the present position of the vehicle as a reference and has a line of sight looking down over the road map so that a part of the road map surrounding the present position of the vehicle can be viewed in an extended scale form and the remaining part of the road map remote from the present position and nearer to the set destination can be viewed in a gradually reduction scale form.

A digital DQPSK modulator according to the present: invention limits respective bands of symbol mapping data of I phase and Q phase obtained by applying differential encoding and mapping processings to a digital baseband signal, and multiplies the obtained data by the carrier signals by means of the digital filter. Such limiting of the bands and multiplication by the carrier signals are carried out by the digital filter in a time-divisionally multiplexed manner. The digital filter includes a circuit, for accumulating symbol mapping data for each of the I phase and the Q phase corresponding to a plurality of symbol sections, a plurality of ROMs corresponding to the plurality of symbol sections for storing a multiplication result of symbol data corresponding to a predetermined filter waveform and the carrier signal, and an adder for adding data output from these ROMs. The adder outputs a digital modulated signal which is, in turn, converted into an analog modulated signal by a D/A converter.
摘要:
Apparatus for demodulating an incoming digitally phase modulated analog signal to reproduce symbol data carried by the signal. Specifically, the demodulator relies on first counting, on a free-running and modulo basis, pulses of a fixed-frequency reference clock signal to form a counted value. The incoming signal is converted to a one-bit phase modulated digital signal. At the occurrence of a pre-defined point in the one-bit phase modulated signal, typically a rising edge occurring at the symbol rate, the counted value is stored as phase information. Within each symbol period, a difference between current and immediately prior counted values, i.e. the latter being a current value but delayed by one symbol period, is determined. This difference, i.e. phase change data, is subsequently sampled and decoded to yield reproduced symbol data, as well as, used, through a phase locked loop, to generate a data clock and the symbol clock.

An image pickup apparatus is provided with an imaging optical system (imaging lens), an image sensor for picking up a subject image formed by the imaging optical system, and a view division optical system (first mirror) which divides a view picked up by the image sensor into an environment imaging side view and an eyeball imaging side view.
