Abstract: A novel imaging apparatus capable of correcting a focus state by an AF detection value both simply and surely has been disclosed. The imaging apparatus comprises an auto-focus drive section for moving a lens, an AF processing section for calculating an AF detection value indicating the focus state from imaging data, a luminance processing section for calculating a luminance value from the imaging data, a correction section for calculating a corrected AF detection value by correcting the calculated AF detection value by the calculated luminance value, and a control section for controlling the auto-focus drive section based on the calculated corrected AF detection value. The imaging data is data not having been subjected to auto-exposure processing.

Abstract: To inform the users of the time necessary for focus to be achieved by changing the focal mark shown on the display monitor, second by second, corresponding to the elapsed time from the start of the auto focus operation until focus is achieved. The users are informed of the status of the auto focusing operations, and have a good idea of how much longer it will take for focusing to be completed. As a result, it increases the probability of users holding the camera still, so as to produce precisely focused photographs.

Abstract: The invention is an image capture device having an image capture element. The device further includes a flicker detection portion which extracts flicker component signals corresponding to periodic changes in brightness in an image capture environment from image signals for each frame supplied by the image capture element, performs correction to remove signals at or below a prescribed reference low-amplitude value, and detects the frequency or the period of the flicker component from the peaks and valleys of the corrected flicker component signal.

Abstract: A multiprocessor system, in which a memory card can be easily accessed from a data processor other than a data processor to which the memory card is connected without impeding processing, has been disclosed. The multiprocessor system comprises data processors wherein a first data processor comprises a memory card interface, a first communication interface, and a first buffer, and another data processor comprises a second communication interface, and when the other data processor reads data from the memory card, the first data processor transmits data after reading the data of the memory card in accordance with the condition of processing and storing the data temporarily in the first buffer and, when the other data processor writes data to the memory card, the first data processor stores the data from the other data processor in the first buffer irrespective of the condition of processing of the first data processor and writes the data to the memory card in accordance with the condition of processing.
