  • Publication number: 20060094565
    Abstract: An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, and an assist actuator controlled by a control unit. A first connecting member of a select lever and a second connecting member of the mode shift unit are relatively movable to a limit amount to each other and integrally movable beyond the limit amount with each other. The actuator is controlled to decrease a relative displacement of the members. When the turn-on of an ignition key is detected, a start-up threshold value is used for judging the assist control and set larger than a normal value for a predetermined period to prevent miss-assist control when a driver touches the lever.

  • Publication number: 20050264663
    Abstract: An image pickup apparatus is disclosed which can remove noise with certainty from an image pickup signal while a high resolution of the image pickup signal is assured regardless of a reading out method of the image pickup signal and achieve reduction of the cost. A light receiving face of a solid-state image pickup device has an image pickup region from which a detection signal corresponding to an image of an image pickup subject formed from light incoming to the light receiving face is outputted as an image pickup signal and a light amount detection region from which a detection signal corresponding to the amount of the light incoming to the light receiving face is outputted as a light amount detection signal. A signal processing circuit of a signal processing section processes the image pickup signal to produce a video signal. A detection circuit detects cyclic variation of the luminosity of a light source from the light amount detection signal.
