  • Patent number: 6476867
    Abstract: In order to realize a photoelectric conversion apparatus capable of easily switching a mode requiring a wide dynamic range in obtaining a motion image and a mode requiring a reduction in noise in obtaining a still image, a mode switching means is used, when a refresh operation is performed for each photoelectric conversion element, to switch between a mode of setting the potential of one electrode of the photoelectric conversion element to be higher than the potential of the other electrode, and a mode of setting the potential of one electrode of the photoelectric conversion element to be lower than the potential of the other electrode, thereby arbitrarily changing the refresh voltage. With this operation, desired photoelectric conversion signals for a motion image and a still image can be obtained.

  • Patent number: 6466731
    Abstract: The object of the present invention is to provide a moving picture processing apparatus capable of preventing the viewer from watching the already watched pictures repeatedly. The moving picture processing apparatus of the present invention records the feature amounts of the already watched pictures in a database every moment and judges whether or not the pictures the viewer is now watching have already been displayed. When the current pictures are what have already been displayed, the apparatus carries out the process of stopping the video output until the time set by the user has been reached. When a list of small screens appears to show pictures, the apparatus carries out the process of displaying only dissimilar pictures on the screen.

  • Patent number: 6442326
    Abstract: A commercial sending system that can easily record a non-recorded commercial material is provided. When a play list is input from a creating block or a receiving block, a CM material DB managing block is asked whether or not CM materials included in the list have been recorded in the system. If a non-recorded CM material is included in the list, the non-recorded CM material is displayed on a sending terminal. In addition, a record list creating block automatically creates a record list for the non-recorded CM material. The record list is displayed on a recording terminal. These operations are performed for all CM materials included in the list.

  • Patent number: 6441852
    Abstract: An extended dynamic range imager. An array of pixels provides an output signal for each pixel related to an amount of light captured for each pixel during an integration period. A row of extended dynamic range (XDR) sample and hold circuits having an XDR sample and hold circuit for each column of the array captures an XDR signal related to a difference between the output signal and an XDR clamp level to which the pixel is reset at a predetermined time before the end of the integration period. A row of linear sample and hold circuits having a linear sample and hold circuit for each column of the array captures a linear signal related to a difference between the output signal and an initial output signal to which the pixel is reset at the beginning of the integration period.

  • Patent number: 6429897
    Abstract: A confocal microscope has a motorized scanning table for moving the sample perpendicularly to the optical axis of the microscope. The object is illuminated simultaneously at many places by means of a light source array. The light reflected or scattered at the object is detected by means of a diaphragm array, which is conjugate to the object and to the light source array. A sensor array is provided as a detector and makes a displacement of charges possible between individual positions in the scanning direction. The sensor is a so-called TDI sensor. The displacement of the charges is synchronized with the motion of the object corresponding to the motion of the image points in the plane of the sensor array. The image data can thereby be recorded during the motion of the object, so that even large object fields can be sensed in a short time with high lateral resolution.

  • Patent number: 6427047
    Abstract: An additional information produced by an additional information signal producing curcuit is spectrum-spread by a spectrum spreading code generated on the basis of the timing of the synchronous signal of digital video signal and is then added to the digital video signal by means of a signal adder. The digital video signal to which the spectrum spread additional information signal is added is then written into a recording medium by a signal writing device. Thereby, the additional information signal can be added to the video signal under the condition that the reproducing quality of the video signal is never deteriorated and alteration and deletion are impossible and moreover the additional information signal can be detected for use as required from the video signal.

  • Patent number: 6404976
    Abstract: Comparators receiving reference voltages are provided. An output signal from a differential amplifier is applied to these comparators. Here, the relationship of Vref1>Vref2>Vref3>Vref4>Vref5>Vbias>Vref6>Vref7>Vref8>Vref9>Vref10 is established. The output signals from the comparators are applied to a data latch/threshold level select circuit. The select circuit retains the maximum peak level of the prior comparison by the comparators, and retains the minimum peak value of the prior comparison by the comparators. The select circuit selects the output signal of the comparator of one lower level than the comparator that detects the maximum peak level at the prior comparison to supply the selected signal to a RS flip-flop circuit, and selects the output signal of the comparator of one higher level than the comparator that detects the minimum peak level at the prior comparison to supply the selected signal to the RS flip-flop circuit.

    Abstract: Image blur prevention apparatus matching signal characteristics of a lens and a camera includes a vibration detecting sensor disposed in the camera for detecting vibration of the camera and providing a vibration signal corresponding thereto. An image blur prevention control circuit is disposed in the lens and controls an image blur prevention operation in accordance with the vibration signal output from the vibration detecting sensor. A determination device determines the relationship between the signal characteristic of the vibration signal and a control characteristic of the image blur prevention control circuit. For example, if the camera contains either an acceleration sensor or a velocity sensor, the output signal will be appropriately converted so that the image blur prevention control circuit can control the image blur prevention operation appropriately.

  • Patent number: 6385386
    Abstract: A personal computer is used as a recording apparatus that is capable of carrying out recording and other processing concurrently without suspending the recording. The personal computer includes an encoder board, a microprocessor, and a hard disk. A recording period of time for recording a program and a bit rate of an MPEG system stream produced by the encoder board as a result of encoding a program are set. The microprocessor computes a recording capacity from the recording period of time and the bit rate. A free area with the size equal to the computed recording capacity is allocated in the hard disc. The free area is used for storing MPEG system stream of a program received typically by a TV tuner employed in the encoder board.
