Abstract: A computer program makes a computer perform: a measuring process of measuring a beat candidate value, which is the number of beats of content per unit time; a reference setting process of setting a beat reference value according to a user's input; and a determining process of determining a beat definite value set in the vicinity of the beat reference value, from among the measured beat candidate value.

Abstract: A computer program makes a computer perform: a measuring process of measuring a beat rate, which is the number of beats of content per unit time; a first detecting process of detecting a beat position; a generating process of generating a beat guide which is to be displayed in accordance with the beat position and which has a substantially uniform interval in accordance with the beat rate along a time axis, on the basis of the beat rate and the beat position; a second detecting process of detecting a positional shift between the beat guide and the beat position; an offset process of adding an offset to a position of the beat guide on the basis of the positional shift; and a displaying process of displaying the beat guide to which the offset is added.

Abstract: A method of reproducing first images and second images simultaneously, synchronizing them with each other. The method includes the processes of: reading first image data representing the first images and second image data representing the second images from a recording medium; storing the first image data into a first memory device and storing the second image data into a second memory device; and separately and simultaneously decoding the first image data and the second image data by using a first decoding device and a second decoding device. In this method, each of the first image data and the second image data is divided into a plurality of data units each having an equal time length and an equal data size, and each of the data units of the first image data and each of the data units of the second image data are alternately arranged on the recording medium.

Abstract: A device for detecting an object by detecting an infrared ray emitted from a moving object. The device includes a plurality of light receiving elements, each being disposed so as to receive infrared rays at a predetermined directional optical angle, and the position of and distance to the object is detected based on detection results by the respective light receiving elements. The moving speed and acceleration of the object are also detected from detection results by the respective light receiving elements, taking time-varying factors into consideration.

Abstract: A digital code decoding apparatus including a reference waveform storage section which prestores, as reference waveforms, at least m received waveforms corresponding to m possible values of m-value digital codes distorted during transmission, a waveform comparing section which compares at least m reference waveforms read out of the reference waveform storage section and the received waveform, respectively, and a decoded information output section which discriminates one of the reference waveforms which most resembles the received waveform, on the basis of the compared outputs from the waveform comparing section, and outputs, as decoded information, a digital code corresponding to the discriminated reference waveform.
