  • Patent number: 7835714
    Abstract: A received low-frequency standard radio wave, which is an amplitude modulation signal, is converted to an intermediate frequency signal Sa, and is output to a detection circuit and an AGC circuit. The detection circuit and AGC circuit generates an RF control signal Sf1 and IF control signal Sf2 from the input intermediate frequency signal Sa, and controls an RF control circuit and IF control circuit by outputting the generated RF control signal Sf1 and IF control signal Sf2 to the RF control circuit and IF control circuit. By this a radio wave reception device can speed up AGC operation.

  • 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: 7825955
    Abstract: Immediately before regular image pickup, a reference image is taken through exposure control by center-weighted photometry. A histogram indicative of a luminance distribution of all pixels is generated on the basis of luminance information of the reference image. Then, a luminance point in the histogram where the accumulated number of pixels from the high-luminance side is equal to a half of the total number of pixels is obtained, and a difference is calculated between the luminance point and a luminance point (“118”) when the brightness is uniform in the reference image. At the time of regular image pickup, proper exposure determined in response to the brightness of the subject when the reference image is taken is compensated with the previously calculated difference, and exposure control for the compensated proper exposure is performed.
