Abstract: In the case where an imaging apparatus is not able to detect the distance to an object placed over an imaging surface thereof, if the area of a bright region in an image of the object captured by an imaging unit with light emitted from a light emitting unit is equal to or greater than a predetermined area, the imaging apparatus determines that the object is close to the imaging apparatus. Thus, it becomes possible to let the user know that the palm is too close to the imaging apparatus and to prompt the user to move the palm away from the imaging apparatus. Accordingly, it becomes possible to smoothly capture an image of the object.

Abstract: A biometrics authentication apparatus acquires biometric information by a biometric information acquisition section and acquires first registered information and second registered information by a registered information acquisition section. The biometrics authentication apparatus generates a comparison score from the first registered information and the biometric information, compares the comparison score and a threshold, and outputs an authentication result, by an authentication section. The biometrics authentication apparatus generates a comparison score for each of combinations of two of the biometric information by which success in authentication is obtained, the first registered information, and the second registered information, evaluates the comparison score, and generates an evaluation result, by a comparison evaluation section.

Abstract: A biometric information acquisition apparatus acquires biometric information to be used for verification. The biometric information acquisition apparatus includes a blood flow increasing unit, a biometric information acquiring unit, a feature amount evaluating unit, and a reacquisition determining unit. The blood flow increasing unit increases blood flow of an object person. The biometric information acquiring unit acquires the biometric information from the object person. The feature amount evaluating unit evaluates the feature amount of the acquired biometric information. The reacquisition determining unit determines whether to cause the blood flow increasing unit to operate and then cause the biometric information acquiring unit to reacquire the biometric information when the evaluated feature amount does not reach a predetermined threshold.

Abstract: A computer system which includes data transmission line and a plurality of data transmissions apparatuses connected in parallel to the data transmission line. Each data transmission apparatus generates transmission data and provides the generated transmission data to the data transmission line. In each data transmission apparatus, the generated transmission data provided to the data transmission line is wrapped around back to the respective data transmission apparatus without passing through any other data transmission apparatus. Each data transmission apparatus includes a data abnormality monitoring unit which determines whether the generated transmission data correlates with the transmission data which was wrapped around. It is determined that an abnormality occurred when the data abnormality monitoring unit determines that the generated transmission data does not correlate with the transmission data which was wrapped around.

Abstract: A transmission rate control system is adapted for an information processing system which exchanges data between a host unit and at least one terminal equipment via a first transmission line. The transmission rate control system includes a first part provided in the host unit for generating a clock switching signal which instructs a switching of a first clock signal which determines an operation of the terminal equipment, a second part provided in the terminal equipment for generating the first clock signal which determines the operation of the terminal equipment, a third part provided in the terminal equipment for switching a period of the first clock signal generated from the second part in response to the clock switching signal received from the main unit, so that a transmission rate of the terminal equipment is switched, and a second transmission line provided exclusively for transmitting the clock switching signal from the host unit to the terminal equipment.
