To provide a system that can accommodate a greater number of terminals within a limited band and can obtain a higher transmission rate. While the number of frequency signals (spectrums) output in parallel by performing a spread spectrum from the DFT unit of each terminal is 12, the number of sub-carriers constituting one sub-channel is set at 10 or 11. In this case, the users (users A and G) allocated to the sub-channels at both ends of the band will not perform transmission of one frequency signal at the end (one sub-carrier) of all the frequency signals output from the DFT unit, whereas the users (users B to F) allocated to the other sub-channels will not perform transmission of the frequency signals at the ends (two sub-carriers). This transmission can be realized by deleting (clipping) the associated number of signals from both ends or from one end of the frequency signals output from the DFT unit of each terminal and allocating the frequency signals after clipping, to individual sub-channels.

A print management apparatus is provided. A print history of a print job data is stored into a first storage component, when a print data identifier of the print job data containing print data, a print data identifier, and a printing parameter is not stored in the first storage component. A printing parameter in the first storage component served as alert information is stored into a second storage component as an alert history, when the print data identifier of the print job data is stored in the first storage component, and a printing parameter stored in the first storage component is not the same as a printing parameter of the print job data. Whether continuing a print or aborting a print is selected, when the print data identifier of the print job data is stored in the second storage component.

A head posture estimating unit estimates, from a face image of a person photographed by a camera, a head posture of the person in a camera coordinate system. A head coordinate system eyeball central position candidate setting unit sets candidates of an eyeball central position in a head coordinate system based on two-point eyeball feature coordinates expressed in the head coordinate system. A camera coordinate system eyeball central position calculating unit calculates an eyeball central position ({right arrow over (a)}) in the camera coordinate system based on the head posture resulting from the estimating of the head posture estimating unit, the candidates of the eyeball central position set by the head coordinate system eyeball central position candidate setting unit, and a pupil central position detected from the face image. An eyeball parameter estimating unit estimates an eyeball central position (O) and an eyeball radius (r) in the head coordinate system based on the eyeball central position ({right arrow over (a)}) in the camera coordinate system.

摘要:
A light-receiving amplifier circuit in which diodes are commonly connected to a differential amplifier circuit including a transistor of a differential input stage that is an inverting input unit, and are connected between photodiodes (PDs) biased in a forward direction with respect to a direction of photocurrent, and current supply switch transistors. Current supply switch transistors are each connected in parallel between a differential input transistor and a corresponding PD. When light enters into a first PD, a corresponding transistor is turned ON, while a non-corresponding transistor is turned OFF. A non-corresponding diode becomes biased in a backward direction, so that a photocurrent generated due to the light having entered into a second PD is prevented from flowing into the differential amplifier circuit.
