Abstract
An image capture apparatus which is compact and structurally simple and allows for prevention of a flicker noise, a method of capturing an image which allows for prevention of a flicker noise, and a mobile terminal using the apparatus and the method, are provided. In the image capture apparatus, a vertical cycle is adjusted so as to maintain 20 fps or 20/2m (m is an integer) fps, thereby to prevent a flicker noise in an image as obtained. To this end, in the image capture apparatus, a frequency of a horizontal transfer clock, a horizontal count level and a vertical line count level may be adjusted. Further, a fraction count is provided to adjust the length of one vertical cycle. Moreover, the image capture apparatus may be incorporated in a mobile terminal.
