Abstract
The image acquiring deviceincludes the voltage control unitwhich generates first voltage information that can identify voltage applied to the first variable-focus lensA included in the first imaging unitinstalled in a position where a subject can be photographed and whose focal length changes in accordance with an applied voltage, and generates second voltage information that can identify voltage applied to the second variable-focus lensA included in the second imaging unitinstalled in the position where the subject can be photographed and whose focal length changes in accordance with an applied voltage, and the image judgment unitwhich inputs images from the first imaging unitand the second imaging unit, and selects one image taken at an in-focus position among input images, wherein the voltage control unitgenerates information, as the first voltage information, that can identify each voltage in a time series of voltages whose values change with time, and generates information, as the second voltage information, that can identify that each of the voltages identified by the first voltage information is applied to the second variable-focus lensA after a predetermined period of delay.
