Abstract: An electronic device with a camera function, an electronic device, a photographing control method, a photographing control program, and a processor is provided with a preventive function to block inappropriate photographing such as spy shots. A photographing reporting section (54, 54A, 54B) issues a reporting information for photographing. An information detecting section (58, 58A, 58B) detects this reporting information and a judging section (image output judging section 60) judges, by using the reporting information detected at the information detecting section, whether or not the photographing is permitted, whether or not an image is stored, and whether or not the image is altered.

Abstract: A pseudorandom signal generator uses two pseudorandom signals having a small correlation with each other to generate a cross-correlation function of the two pseudorandom signals, and to output a value of the cross-correlation function as a new pseudorandom signal. As the new pseudorandom signal as a result has random phases and random amplitudes, many new pseudorandom signals can be generated by the two existing pseudorandom signals.

Abstract: Regarding an electronic device with a camera function, an electronic device, a photographing control method, a photographing control program, and a processor in which a preventive function to block inappropriate photographing such as spy shots is enhanced are provided. A photographing reporting section (54, 54A, 54B) issues a reporting information for photographing; an information detecting section (58, 58A, 58B) detects this reporting information; and a judging section (image output judging section 60) judges whether or not the photographing is permitted, whether or not an image is stored, and whether or not the image is altered by using the reporting information detected at the information detecting section.

Abstract: The invention relates to a controlling equipment for properly maintaining a length of a period where an oscillator is to operate and also relates to a radio equipment incorporating such a controlling equipment. The oscillator is to supply a predetermined signal to a circuit that intermittently operates. A length of time, which is between a first instant and a second instant when the oscillator and the circuit are to initiate operation, respectively, is varied in accordance with a length of time from an initiation of operation of the oscillator to an output signal of the oscillator satisfying a predetermined condition. In an equipment or a system to which the invention is applied, it is possible to flexibly adapt to deviation or fluctuation in its characteristics and to reduce the power consumption.

Abstract: The present invention is arranged to use two pseudorandom signals having a small correlation with each other, to generate a cross-correlation function of the above-mentioned two pseudorandom signals, and to output a value of the above-mentioned cross-correlation function as a new pseudorandom signal; accordingly, the new pseudorandom signal per se has random phases and random amplitudes; thus, when there are a plurality of existing pseudorandom signals, a multitude of new pseudorandom signals can be generated by selecting two of the existing pseudorandom signals.
