  • Patent number: 8035729
    Abstract: In a digital camera 1, in an automatic shooting stand-by state, when judged at Step S26 that an automatic shooting condition has been satisfied (N at Step S26), whether or not to issue an AE re-processing command is judged. In other words, whether or not the current shooting condition is similar to a condition where an automatic shooting condition is satisfied is judged. When judged to issue the AE re-processing command, exposure tracking in an aperture-priority mode is performed (S28), and shooting exposure conditions excluding the aperture value for still-image shooting in the aperture-priority mode are determined. Then, the storage is updated (Step 29), and the process returns to Step S26. When judged at Step S26 that an automatic shooting condition has been satisfied (Y at Step S26), record processing for still-image shooting is performed with the updated shooting exposure conditions without changing the aperture value (Step S30).

  • Patent number: 7995912
    Abstract: When the mode is set to a strobe consecutive shooting mode, an imaging apparatus sets the mode to a pixel addition drive mode for reading out image data using pixel addition drive, performs metering operation using preliminary flashing and calculates an appropriate amount of flashing on the basis of the metering operation. Next, the imaging apparatus judges whether or not it is possible to flash three times consecutively with the calculated amount of flashing. If it is judged that it is not possible to flash three times consecutively with the calculated amount of flashing, the imaging apparatus limits the amount of flashing to the largest amount of flashing within the range of amounts of flashing with which flashing of strobe light three times consecutively is possible, and performs strobe consecutive shooting with the limited amount of flashing.

  • Patent number: 7835639
    Abstract: When the mode is set to a strobe consecutive shooting mode, an imaging apparatus sets the mode to a pixel addition drive mode for reading out image data using pixel addition drive (S7), performs metering operation using preliminary flashing (S8) and calculates an appropriate amount of flashing on the basis of the metering operation (S9). Next, the imaging apparatus judges whether or not it is possible to flash three times consecutively with the calculated amount of flashing (S10). If it is judged that it is not possible to flash three times consecutively with the calculated amount of flashing (NO in S10), the imaging apparatus limits the amount of flashing to the largest amount of flashing within the range of amounts of flashing with which flashing of strobe light three times consecutively is possible (S11), and performs strobe consecutive shooting with the limited amount of flashing (S13 to S17).

  • Patent number: 7826662
    Abstract: A histogram is generated from image data, and two distribution areas are detected. A gamma curve used for gamma correction of the image data is changed into a gamma curve corresponding to the luminance ranges of the two distribution areas. The luminance values of each pixel in the two distribution areas are converted by the gamma correction using the changed gamma curve, and the luminance ranges of the two distribution areas are expanded to the higher luminance side while the relative relation of the luminance the pixels is maintained.

  • Patent number: 7428013
    Abstract: PDs and vertical CCDs are formed on CCD. A control unit drives the CCD by one of a first image pickup mode for executing an exposure and reading the electric charges on the vertical CCDs and transferring those, and a second image pickup mode for setting an electric charge sweep-out period in which the electric charges are swept out by applying a plurality of vertical shift clocks to the vertical CCDs within a period from a time when a transfer period in which the electric charges obtained by exposing the PDs are read on the vertical CCDs and transferred those is terminated up to a time when a next transfer period is started.

  • Patent number: 7409151
    Abstract: In a photographing apparatus, while a deterioration of a contrast characteristic caused by an optical zooming operation is prevented, superior photographic images are continuously acquired. Magnification set by an optical zooming function is acquired, and a gamma curve, namely gradation correcting information is set to a gamma lookup table, while the gamma curve is applied during a photographing operation based upon the acquired set magnification. A gamma correcting unit corrects gradation of image data (namely, RAW data) outputted from an imaging element by employing gradation correcting information set in this gamma lookup table.
