Abstract: An obstacle detection device includes a detector, a generator, and an estimator. The detector detects a person region where a shape of a person is present, from a captured image. The generator generates an optical flow based on a non-detection image from which the person region is not detected and a detection image from which the person region is detected before the time of the non-detection image in a case where the person region is not detected by the detector. The estimator estimates the person region in the non-detection image based on the optical flow generated by the generator.

Abstract: A drive recorder and a drive recorder system that can check the content of the image captured by an image capturing unit that outputs a video signal at a frequency not affected by LED traffic light flashing. The drive recorder includes an image converting unit for converting a received video signal into image information, and for outputting the image information in the form of a video signal, a storage unit for storing the converted image information, and a control unit for performing control so that the video signal is converted into the image information by using a first frequency not affected by LED traffic light flashing, and so that the image information stored in the storage unit is output in the form of a video signal by using a second frequency corresponding to a standard video signal.

Abstract: The present invention is to provide an electric display device turning base capable of stabilizing and turning a direction of a thin-screen display device. This display device turning base is provided with a first base portion; a mounting and fixing portion; a pair of arc guide rails installed in the mounting and fixing portion in such a manner that a center point of an arc thereof is arranged on a horizontal line passing through a gravity center of the thin-screen display device mounted and fixed to the mounting and fixing portion and extending in a left and right direction; a support roller for supporting the arc guide rails turnably around the horizontal line in a state that the center point of the arc guide rails is arranged on the horizontal line, the support roller being rotatably installed in the first base portion in a standing manner; and an electric drive mechanism for turning the arc guide rails around the horizontal line.

Abstract: The invention provides an automatically rotatable turntable for a display unit and includes: a mounting section mounted with the display unit; an electric rotating mechanism that rotates the mounting section; a reception section in the display unit which receives a wireless signal from a remote control unit; and a control section that controls the electric rotating mechanism based upon the received wireless signal. Upon receipt of the wireless signal, the control section detects a reception strength of the reception section while cyclically rotating the mounting section around a predetermined rotational position, to initially detect a rotational position at which the reception strength is maximum. Thereafter, as a main operation, the control section detects the reception strength while rotating the mounting section in a direction extending from the predetermined rotational position to the initially-detected rotational position, to detect a rotational position at which the reception strength is maximum.

Abstract: The invention provides a rotating table for a display device which can rotate around the horizontal shaft by a manual operation in addition to a small motor drive. A rotating table for a display device includes a rotating member arranged so as to be rotatable around a horizontal shaft, and in which the display device is arranged, a balancing device balancing with a gravity moment around the horizontal shaft in the display device, and a first motor-driven rotating mechanism rotating the rotating member around the horizontal shaft, and the first motor-driven rotating mechanism includes gear trains converting a rotation of an electric motor into a rotation of the rotating member, and a rotation allowing device allowing a rotation of the gear trains only in a case of a rotation having a torque not less than a predetermined torque with respect to the rotation from the rotating member side.

Abstract: A vehicle information recording apparatus which is capable of recording information to be recorded on a recording medium without fail even in a case where electric power is supplied in a limited quantity is provided. Under the circumstances where a signal indicative of a command to record the information of images taken by a camera is issued and a main power source's power detection portion detects the absence of electric power supply from a vehicle power source, a CPU performs a second recording operation which differs from a first recording operation in a manner that a predetermined part of the image information stored in a second SD-RAM on a frame-by-frame basis can be recorded on a CF card by exploiting the electric power supply from a backup power source section.
