  • Patent number: 7839433
    Abstract: An imaging apparatus which can correct a shaking of the hand whether a moving picture is taken or a still picture is taken. Exposure is carried out within a shorter time than a predetermined exposure time to output a charge. Exposure and delivery of charge is carried out plural times to accumulate charges. An address for accumulation is changed in accordance with information of a shaking occurring within the shorter time and a signal due to the shaking and a signal before the shaking are accumulated at the address. Alternatively, a camera-shake is detected by using a sensor such as a gyroscope adapted to detect an angular velocity or an acceleration of a shaking of the imaging apparatus itself.

  • Patent number: 7340160
    Abstract: Disclosed is an imaging apparatus capable of realizing a camera shake correction function while reducing the size and power consumption of the apparatus without deteriorating the use efficiency of an image sensor thereof. An imaging device has photoelectric conversion elements arranged two-dimensionally and a transfer path for transferring electric charge converted by the photoelectric conversion element. A motion detection unit detects motion of the apparatus according to timing pulses generated by a time management circuit at shorter intervals than exposure time. A drive circuit transfers the electric charge previously read onto the transfer path for a predetermined distance according to the detected motion. Electric charge newly read out and converted by the photoelectric conversion elements at the intervals of the timing pulses is added to the previous electric charge which has been transferred on transfer path.
