Patent ID: 8514320

Claim:
An electronic camera that adjusts a distance from a focus lens to a photoelectronic imaging device, comprising: a determiner which determines a focal level on the basis of an image signal outputted from said photoelectronic imaging device when a distance adjusting instruction is applied, the determiner further using the determined focal level to determine an initial position of the focus lens; a settler which settles an initial value of said distance on the basis of a determination result of said determiner by moving one of the focus lens and the photoelectronic imaging device in a first direction; a changer which gradually changes in a series of steps said distance toward an optimum value using said initial value settled by said settler as a reference by moving said one of the focus lens and the photoelectronic device in a second direction, the second direction being opposite to the first direction; and an optimum value setter which sets said distance to said optimum value on the basis of the image signal outputted from said photoelectronic imaging device in each step changed by said changer.
