Patent ID: 8203623

Claim:
An image capture device, comprising: an image detection unit configured for forming a plurality of consecutive preview images at a predetermined rate with a parameter of the image capture device; and a flicker elimination unit configured for acquiring an exposure count of each of the preview images, plotting the exposure counts to form a waveform on the time axis, determining whether or not the waveform is fluctuating, analyzing information of the waveform to allow determination of modulation of the parameter if the waveform is fluctuating, and performing the modulation of the parameter to cause the parameter varying as a reverse waveform on the time axis that smoothes the amplitude of the waveform trending to a straight line according to the analyzing; wherein the exposure count is represented by the formula: EV=AV+TV=BV+SV wherein EV represents the exposure count, AV represents an aperture value of the image capture device, TV represents an exposure time of the image capture device, BV represents a brightness value of each of the preview images, and SV represents an automatic gain control value of the image capture device.
