Claims (4)
前記フォーカスレンズを予め決められた範囲移動させ、当該予め決められた範囲のフォーカスレンズの移動に伴って得られる撮像手段からの出力信号に基づいて焦点状態を判断し、被写体像が合焦状態となるよう前記駆動手段を制御する制御手段と、
複数回撮像を行うよう指示する指示手段とを備え、
前記指示手段の指示があった場合、前記制御手段は、複数回のそれぞれの撮像の前に前記予め決められた範囲のフォーカスレンズの移動を所定速度で行い焦点状態を判断するとともに、当該所定速度での移動の前に当該焦点状態を判断する位置へ当該所定速度よりも速い速度で前記フォーカスレンズを移動させることを特徴とする焦点調節装置。 Driving means for driving the focus lens;
The focus lens is moved in a predetermined range, the focus state is determined based on an output signal from the imaging means obtained along with the movement of the focus lens in the predetermined range, and the subject image is in a focused state. Control means for controlling the drive means to be
An instruction means for instructing to perform imaging a plurality of times,
When there is an instruction from the instruction means, the control means judges the focus state by moving the focus lens within the predetermined range at a predetermined speed before each of the plurality of imaging operations, and determines the focus state. A focus adjustment apparatus, wherein the focus lens is moved at a speed faster than the predetermined speed to a position where the focus state is determined before the movement at.
前記指示手段の指示があった場合、複数回のそれぞれの撮像の前に前記予め決められた範囲のフォーカスレンズの移動を所定速度で行い焦点状態を判断するとともに、当該所定速度での移動の前に当該焦点状態を判断する位置へ当該所定速度よりも速い速度で前記フォーカスレンズを移動させることを特徴とする制御方法。 A focus unit is determined based on an output signal from the imaging unit obtained by moving the focus lens and a drive unit that drives the focus lens and moving the focus lens in a predetermined range and moving the focus lens in the predetermined range. And a control method of a focus adjustment apparatus comprising: a control unit that controls the driving unit so that a subject image is in focus; and an instruction unit that instructs to perform imaging a plurality of times.
When there is an instruction from the instruction means, the focus lens within the predetermined range is moved at a predetermined speed before each imaging for a plurality of times to determine the focus state, and before the movement at the predetermined speed. And moving the focus lens to a position for determining the focus state at a speed faster than the predetermined speed.
