  • Patent number: 8699863
    Abstract: A video recording apparatus provides a slow motion effect or a quick motion effect by digitally converting the frame-rate instead of by changing the playback speed of the film, and using few recording media without requiring any special device at playing. A picture encoding part encodes only valid frames by changing a rate-controlling method so that a predetermined playing frame-rate is obtained at a standard data-rate at playing. And a TS multiplexing part multiplexes by converting a frequency of a standard STC clock by only a ratio of valid frame-rate and playing frame-rate, and generating values for PCR, PTS, and DTS.

  • Patent number: 8599451
    Abstract: A sheet conveyance device that is capable of correcting skew of a sheet like an index sheet without complicating a use setting and without increasing a cost significantly. A plurality of conveyance units are arranged in a direction intersecting a sheet conveyance direction to convey a sheet. At least three detection sensors are arranged in a direction intersecting the conveyance direction at an upstream side from the conveyance units to detect the sheet. A skew amount computation unit measures a time difference between detection timings of a front end of the sheet by two of the at least three detection sensors except the detection sensor that detects first, and computes a front-end skew amount according to the time difference. A speed change unit makes the conveyance speeds of the conveyance units be different according to the front-end skew amount so as to correct the skew of the sheet.

  • Patent number: 8587281
    Abstract: An operation controller has a reference voltage generator, a starter circuit, and a switch element. The reference voltage generator is connected to an enable terminal to which an enable signal is supplied. After the enable signal is supplied and a start signal is generated, the reference voltage generator generates a reference voltage up to a stable value. After the reference voltage rises to the stable value, it generates a stop signal. When the enable signal is supplied, the starter circuit generates the start signal, and supplies it to the reference voltage generator. When the enable signal is no longer supplied or the stop signal is generated, the start signal is terminated. The switch element has one end connected to the enable terminal and the other end supplied with a prescribed voltage; it turns on when the start signal is generated, and turns off when the start signal is terminated.
