  • Publication number: 20020196356
    Abstract: The number of terminals for a timing signal generating device and the vertical drive device for a solid-state image pickup element is to be reduced, and at the same time the circuit dimensions of the timing signal generating device and the vertical drive device which are increased by the reduction in the number of terminals are to be kept to the minimum. A timing signal generating circuit is provided with a time-division multiplexing circuit, and this time-division multiplexing circuit subjects timing signals vertical transfer pulses and timing signals for read pulses to time-division multiplexing. On the other hand, a vertical driver is provided with a demultiplexing circuit, and the demultiplexing circuit separates four-bit signals subjected to time-division multiplexing into the original timing signals and timing signals. This enables the number of terminals (the number of signal lines) of the timing signal generating circuit and the time-division multiplexing circuit to be reduced.

  • Patent number: 6460958
    Abstract: Ejection nozzles (152a-152g) are located in a nozzle surface (153) of an ejection head (150). A distance (H: Ha-Hg) between each of the ejection nozzles (152a-152g) and a printing object (109) is obtained and compared with a permissible distance (H0) which is determined by the required level of print quality. The ejection nozzles (152a-152d) whose distances (H) from the printing object (109) are not more than the permissible distance (H0) are enabled for ink ejection, while the ejection nozzles (152e-152g) whose distances (H) are greater than the permissible distance (H0) are disabled for ink ejection. The surface of a printing object (228) is divided into a plurality of target areas (205), each of which is then approximated by a projective plane (206). Then, image data about a projected image (208) which is obtained by orthogonal projection of a print image (207) onto the projective planes (206), is obtained from print image data about an image to be printed on the surface of the printing object (228).

  • Publication number: 20020057903
    Abstract: An image data processing method transforms a picture signal having a broad dynamic range to another picture signal having a narrow dynamic range. The picture signal having the narrow dynamic range is subjected to inverse transform to thereby output a recovered signal having the broad dynamic range. A difference between the original picture signal and the recovered signal, both having the broad dynamic range, is produced and then stored in a recording medium as difference data. A parameter for software processing to be executed for reproduction of the original picture signal later is also stored in the recording medium. In this way, the method can transform the original data with the broad dynamic range to the data of a standard file format with the narrow dynamic range, record the transformed data, and allow the original data to be recovered and effectively used later, as desired.

    Abstract: A timing signal generating device capable of generating different kinds of signals is disclosed. A first, a second and a third data setting circuit each generate a particular kind of set data for generating corresponding timing signals. The set data are selectively set in a timing pulse generating circuit at the time of start-up of a camera or similar system, which includes the device, or in accordance with the operation mode of the system. The timing pulse generating circuit generates timing signals based on the set data. The timing signals are fed to a solid-state image pickup section and a signal processing section, causing them to operate in accordance with the timing signals.

  • Publication number: 20010045678
    Abstract: To replenish a powder supply section (40) with a powder material, a powder-material reservoir (30) is mounted in a reservoir placement section (43) located on the upper side of the powder supply section (40). After the completion of a modeling operation on a modeling stage (62) in a modeling mechanism (60), the modeling stage (62) is lowered and a carrier mechanism (65) operates to carry a mesh tray (9) and a three-dimensional (3D) object (91) on the modeling stage (62) to a treatment chamber (72). In the treatment chamber (72), removal of unbound powder adhering to the 3D object (91) and post-processing are performed automatically. Such a configuration allows automatic fabrication of a 3D object of high binding strength without scattering the powder material therearound.

  • Patent number: 6211914
    Abstract: A solid-state image sensing device compensates for reset noise by integrated correlated double sampling to determine a difference between a reference signal obtained in a feed through period and a video signal obtained in a video signal time period. The device reduces the effect of high-frequency noise through integration. The problem of small CCD output affecting the linearity of integration is compensated by an integration coefficient control device that controls an integration coefficient of an integrating circuit. The integration coefficient control device performs this control in dependence on an applied control signal. Under low light conditions, a control signal applied to the integration coefficient control device changes the integration coefficient so that an integrated value of the integrating circuit is enlarged. The enlarged integrated value of the integrating circuit provides improved linearity and makes the apparatus less susceptible to noise from other circuits.

  • Patent number: 5452005
    Abstract: In an automatic focusing device for an imaging apparatus, a band-pass filter separates high frequency components from a luminance signal. A window processing section extracts a part of the output of the band-pass filter which lies in a predetermined focus area. In a slice circuit, a first and a second high level priority circuit slice respectively positive components and negative components, which constitute the extracted signal, on the basis of a reference voltage generated by a reference voltage source. A differential amplifier amplifies a difference between the outputs of the two high level priority circuits. An absolute value circuit regulates the amplified signal to a predetermined polarity. A peak hold circuit transforms the output of the absolute value circuit to a sampled peak value signal. An integrating circuit integrates the peak values of the peak value signals every predetermined period of time so as to calculate an evaluation value for focusing.
