  • Patent number: 7336308
    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 ?)=(G exposure duration tG)/(R/B exposure duration tR/B)=(G exposure duration tG)/((G exposure duration tG)+(exposure duration difference ?t)).

  • Patent number: 7333144
    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.

  • Patent number: 7324136
    Abstract: The electronic camera, and image display method and image recording method applied thereto are capable of eliminating discontinuity in moving image caused by a camera control such as interruption by still image recording in moving image capturing and aperture switching. With respect to the period during which the capturing of the image data of moving image is interrupted, an image picked-up immediately before the interruption is repeatedly displayed or recorded. As to the moving image recording, supplementary recording for non-recording period may be performed afterward by utilizing an image immediately after resuming the reading of movie image. Moreover, display of non-image screen (“non-display”), recording of black screen (“black recording”) or display or recording of a special image can be inserted if necessary, thus giving an impression that the shutter is clicked.

  • Patent number: 7271833
    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.

  • Patent number: 7256829
    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.

  • Patent number: 7190403
    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: 7053950
    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.
