Abstract: A passenger transportation system includes: an abnormality determination unit configured to determine whether or not a passenger feeling unwell is present in a vehicle; a transportation planning unit configured to determine, when it is determined that the passenger feeling unwell is present, a medical facility to which the passenger feeling unwell is transported and a via-point where normal passengers are dropped off; and a vehicle control unit configured to control the vehicle to travel so as to transport the passenger feeling unwell to the medical facility via the via-point.

Abstract: A bus dispatch device includes a vehicle dispatch unit that determines, based on external environment information, a ratio between various classes of in-service buses having different states of a specific amenity.

Abstract: A color image display control apparatus for receiving a composite color picture signal and processing color image data included in the signal. A color picture signal in an analog form included in the composite color picture signal is converted to a digital form by sampling the analog signal at each cycle of a sampling clock, in and analog to digital converter. The digital image data is processed in a digital image processing circuit. Processed digital data is converted to analog data in a digital to analog converter. Information regarding a phase difference between the sampling clock and each horizontal synchronizing signal in the composite color picture signal is obtained. According to the information, a digital image data in a line corresponding to each horizontal synchronizing signal, which was sampled by the sampling clock, is modified so that the influence of the above phase difference on a displayed image of the processed image data is corrected.

Abstract: A composite video signal generation method and device comprises circuits for processing a digital signal, by which the circuits can be integrated. The method comprises the steps of calculating a digital luminance signal and two digital chrominance signals combined from digital primary color component signals, balance-modulating a subcarrier by the two digital chrominance signals, and combining the balance-modulated signals and the luminance signal. In the balance-modulation step, a series of phase information values by adding one by one a value of a sampling period of the digital primary color component signal per a subcarrier period is obtained, cosine function values and sine function values are operated in response to the phase information values, and the cosine function values and the sine function values are multiplied by the two digital chrominance signals, respectively.
