  • Publication number: 20050200721
    Abstract: A digital camera that captures object light by a CCD to create an image signal includes a read controller that controls reading of light signals from at least two fields of the CCD, in which a field, from which a light signal received by an R-sensor sensitive to red light is read, is separated from a field from which a light signal received by a B-sensor sensitive to blue light is read. The read controller includes: a color temperature discriminating section that discriminates a color temperature based on the light signals received from the CCD; and a read sequence controller that causes a light signal to be read first from the R-sensor when a color temperature is low and causes a light signal to be read first from the B-sensor when the color temperature is high according to a result of discrimination of the color temperature discriminating section.

  • Patent number: 6896839
    Abstract: To provide a three-dimensional molding technique capable of generating a three-dimensional molded article in short time. In a three-dimensional molding apparatus, a powder material is allowed to drop via an opening while moving a thin layer formation section in the +X direction, thereby forming a powder layer on a molding stage. With respect to a selected region in the powder layer, a binder of ultraviolet-ray hardening resin is discharged from a head section. Then, the powder layer is irradiated with ultraviolet rays from an ultraviolet irradiation section, making the ultraviolet-ray hardening resin applied on the powder layer harden to thereby bind the powder material. By repeating this operation with respect to the powder layer which is sequentially formed, a three-dimensional molded article is formed.

  • Publication number: 20040206885
    Abstract: Disclosed is a horizontal transfer line in which first horizontal transfer pulses are applied to transfer electrodes via a commonly connected electrode line, second horizontal transfer pulses are applied to transfer electrodes via a commonly connected electrode line, and final horizontal transfer pulses are applied to a final transfer electrode via an electrode line independent of the above-mentioned electrode lines. Since the independent electrode line is independent of the other electrode lines, amount of capacitance produced in equivalent terms is reduced. The final transfer pulses exhibit a steep characteristic, thereby improving transfer efficiency. The input/output characteristic of the horizontal transfer line is improved as a result.

  • Publication number: 20040160520
    Abstract: Intentionally defective pixels, whose number exceeds a storage capacity of a memory for defect correction, are formed in a predetermined pattern in an image pickup device. There is a plurality of patterns of the defective pixels, each being unique to each camera (image pickup device). An ID of the camera for specifying the pattern is read and defect pattern data corresponding to the ID of the camera is retrieved. Image data is read and the intentionally defective pixels are corrected based on the retrieved defect pattern data. Since the number of the intentionally defective pixels exceeds the storage capacity of the memory for defect correction, the image data cannot be reproduced in a normal manner when the defect pattern data corresponding to the pattern of the intentionally defective pixels cannot be retrieved. Thus, the image pickup device of the camera cannot be used in another image pickup apparatus by a third party.

  • Publication number: 20040033071
    Abstract: An electronic flash device and a camera which can smoothly display a video even though preliminary emission for red-eye reduction in photographing the video are obtained. A timing generator generates a preliminary emission signal such that preliminary emission for red-eye reduction by a light emitting tube is performed in a period of operation of an electronic shutter arranged in an interline CCD to input the preliminary emission signal to a trigger circuit. The timing generator sets a period in which the preliminary emission signal is set at an active level as a period corresponding to a cycle between the edge of a pulse of a transfer gate signal serving as for transferring signal charges from a light-receiving element of the CCD to a vertical transfer path and the edge of a pulse of an overflow drain signal representing a timing at which excess charges are drained by an overflow drain of the CCD.

  • Publication number: 20040017498
    Abstract: A solid-state image pickup apparatus includes a timing signal generator for generating timing signals. Particular gates formed in each of photosensitive cells arranged in an image pickup section are driven independently or simultaneously in response to the timing signals. In an independent drive mode, outputs each having particular sensitivity are obtained from the different photosensitive regions of the individual cell by one time of exposure, covering a range of sensitivity as broad as one achievable with repeated photometry. This reduces the number of times of photometry for determining adequate exposure. In a simultaneous drive mode, outputs are produced in the usual manner. An exposure value calculator converts the resulting image signals to values having a predetermined format while an exposure parameter determining section determines exposure parameters if those values are adequate.

  • Patent number: 6680751
    Abstract: A timing pulse generating apparatus generates a variety of timing pulses used for acquiring image signals from a solid-state imaging device. A horizontal-ROM stores pattern data representing timing pulses for one period first generated in a horizontal scanning period and repeat times of the timing pulses for one period in the horizontal scanning period. Appropriate pattern data is read from the horizontal-ROM and set in a horizontal-register. A timing pulse generating circuit generates timing pulses in accordance with a count value of a horizontal-counter and the pattern data set in the horizontal-register. Thus, the amount of the pattern data is small even if the repeat times of the timing pulses for one period in the horizontal scanning period are large.

  • Publication number: 20030169357
    Abstract: Voltage signals outputted from a CCD are subjected to correlated double sampling processing by a correlated double sampling circuit (CDS), after which digital gain processing is carried out at a gain control amplifier (GCA). A gain difference between G color signals and R/B color signals outputted from the CCD is caused by a difference between a G exposure duration tG and an R/B exposure duration tR/B. When the value of a ratio between the tG and the tR/B falls below a predetermined value, the GCA applies digital gain for compensating for the gain difference by multiplying respective signal values of R, G and B by gain correction coefficients as follows: (gain compensation coefficient &agr;)=(G exposure duration tG)/(R/B exposure duration tR/B)=(G exposure duration tG)/((G exposure duration tG)+(exposure duration difference &Dgr;t)).

  • Publication number: 20030128286
    Abstract: An imaging apparatus with a timing generator supplying an imaging device with drive pulses. The timing generator has registers for independently storing information required for generating a pulse pattern for the imaging device. A selector selects one of the registers to connect it to a pulse generator. Based on the information stored in the selected register, the pulse generator generates pulses of a pulse pattern for the imaging device. External control circuitry rewrites the information stored in an unselected register from the outside of the timing generator. By repeating the steps of selecting one of the registers and rewriting the information stored in the unselected register, drive pulses with various pulse patterns can be supplied to the imaging device.
