Image acquiring device, image acquiring method, and image processing device

Abstract

The image acquiring device 10 includes the voltage control unit 30 which generates first voltage information that can identify voltage applied to the first variable-focus lens 20A included in the first imaging unit 20 installed 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 lens 21A included in the second imaging unit 21 installed in the position where the subject can be photographed and whose focal length changes in accordance with an applied voltage, and the image judgment unit 40 which inputs images from the first imaging unit 20 and the second imaging unit 21, and selects one image taken at an in-focus position among input images, wherein the voltage control unit 30 generates 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 lens 21A after a predetermined period of delay.
