  • Patent number: 9747664
    Abstract: An image processing apparatus includes: an image processor which: receives a captured-image from an image acquisition part acquiring the captured-image from a camera that captures an image of a vicinity of a vehicle; project data of the captured-image onto a virtual projection plane provided in the vicinity of the vehicle; and correct deformation of the captured-image caused by projection of the captured-image onto the virtual projection plane. In a case of presence of a command indicative of enlarging a portion of the captured-image, the image processor corrects the deformation of the captured-image by using a greater correction amount than that used in a case of absence of the input of the command indicative of enlarging the portion of the captured-image. Accordingly, in a case where a portion of an image of a vicinity of a vehicle is enlarged, deterioration of image quality can be suppressed as much as possible.

  • Patent number: 9736582
    Abstract: An audio amplifier and a warning sound amplifier are connected in parallel to each other, relative to a voice coil of a loudspeaker. A resistor having an impedance greater than an impedance of the voice coil is connected to the voice coil and is also connected to the warning sound amplifier. An audio signal from the warning sound amplifier is input to the voice coil via the resistor. Thus, since the warning sound amplifier is connected to the resistor having the impedance greater than the impedance of the voice coil of the loudspeaker, even in a case where only the audio amplifier is operated, a large current is prevented from flowing into the warning sound amplifier.

  • Publication number: 20170225572
    Abstract: A weld detection apparatus is mounted on a vehicle and measures first and second voltages of a first capacitor. The first voltage is measured when the first capacitor is charged while connected in series to a power supply and a ground of a vehicle body while switches that connect the power supply to a load circuit are controlled to be in a first state. The second voltage is measured at a predetermined timing, when the first capacitor is charged while connected in series to the power supply and the ground of the vehicle body while the switches are controlled to be in a second state different from the first state. The apparatus performs a weld detection process to decide which of the switches is welded in an ON-state when a difference between the first and second voltages is equal to or smaller than a predetermined threshold value.
