  • Publication number: 20130027355
    Abstract: The present invention provides an input display device including: a display device which recognizes an input position with a light sensor by blinking a backlight; and an input device of a light-emitting type (light pen), wherein a light emitting diode (LED) of the input device is adapted so that (i) its non-light-emitting period overlaps at least a part of a period (X) during which the backlight is OFF and (ii) its light-emitting period overlaps at least a part of a period (Y) during which the backlight is ON. According to this arrangement, it is possible to realize an input display device which can reduce the effect of ambient light and in which a light pen can be used (in addition to a finger and a reflective pen etc.) as inputting means.

  • Patent number: 6738094
    Abstract: A video camera includes an abutment piece which is perpendicularly placed on the anterior side of the bottom of a stand portion and abuts on an attachment body to which the video camera is to be attached, a lever portion which is rotatably attached on the posterior side of the bottom of the stand portion, and bias means for biasing the lever potion toward the bottom of the stand portion. The lever portion includes an abutment portion formed such that it abuts on the abutment body. The lever portion holds the attachment body between the abutment portion and the abutment piece when it is used, and is housed in the stand portion such that it is pressurized to abut on the stand portion when it is not used. This structure enables the video camera to easily be attached to and detached from various attachment bodies such as flat display that are different from each other in thickness.

  • Patent number: 5585856
    Abstract: Digital image data obtained by A/D converting an output signal from an image sensing device by an A/D conversion circuit is converted into image data corresponding to a predetermined image format by a digital process of an image conversion circuit. Therefore, an image of higher quality without deterioration in the picture can be provided in comparison with the case where digital image data obtained by A/D converting an output signal from an image sensing device is first converted into analog video data and then into A/D data. Further format conversion can be performed using a series of controllable image converters. The image converters and a signal processing unit can be selectively programmed to perform a variety of format conversions and image-type specific signal processing, respectively. Programming can be performed manually or automatically according to the type of input device or the type of information in the image.

  • Patent number: 4812815
    Abstract: A D/A converter system for converting digital signal to analog signal includes a circuit for converting digital signal such as PCM signal to pulse density modulation signal, and an analog low-pass filter for converting the pulse density modulation signal to analog signal by removing noise from the pulse density modulation signal.
