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.

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.

Image pickup device and focusing notification method

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.

Image capture device capable of flicker detection

In a device for processing data signals, a storing part stores an input signal and the data signals included in the input signal are extracted from the storing part and the data signals are output at a desired output speed. Then, the data signal is output based on storage information of the input signal.
