In a display apparatus, a projected member is arranged in a direction in which a driver of a moving body looks while driving, from the perspective of the driver. A projecting unit projects at least one display object in a position that overlaps a background that is visible to the driver through the projected member, so as to be displayed in a superimposed manner as a virtual image. A measuring unit measures a luminance value of the background. A control unit determines a luminance value of the display object based on the luminance value of the background measured by the measuring unit, chromaticity values of the display object, and a sense of superimposition that is a value having a range of 0 or greater and 100 or less, and controls the projecting unit such that the display object is projected at the luminance value of the display object.

For the purpose of efficient transmission based on the UWB system, first and second baseband waveforms are generated at a cycle equivalent to an integral multiple of a carrier to have a specified phase difference from each other. The first baseband waveform is multiplied by the carrier and a first transmission data sequence to acquire a first transmission waveform. The second baseband waveform is multiplied by a phase shifted carrier and a second transmission data sequence to acquire a second transmission waveform. The first transmission waveform is mixed with the second transmission waveform to acquire a transmission signal. The transmission signal is transmitted as a &#x3c0;/2 shift BPSK signal to transmit a UWB signal. Selecting the baseband waveforms and the carrier makes it possible to configure the transmission band and easily provide division multiplexing transmission.

Transmission method, transmitter, reception method, and receiver

A system and method for performing ranging and positioning as follows by using the procedure for packet transmission and reception between a sender and a recipient. A first radio set transmits packets to a second radio set as a recipient. The second radio set returns the packets without fail after the lapse of time (from the detection of packets) which corresponds to an integral multiple of a prescribed unit time. The first radio set counts, by using its counter, the time which has elapsed from its transmission of packets to its detection of packets from the second radio set. The remainder of the thus counted time after subtraction of the time taken by the second radio set from packet detection to packet return and the processing time of the first radio set itself is converted into the distance of propagation between the first radio set and the second radio set as a recipient.
