Title:
IMAGE ACQUIRING DEVICE, IMAGE ACQUIRING METHOD, AND IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/171586
Kind Code:
A1
Abstract:
This image acquiring device 10 includes: a voltage control unit 30 that generates first voltage information for enabling the identification of a voltage applied to a first varifocal lens 20A which is included in a first imaging unit 20 which is installed at a position enabling the imaging of a subject, and the focal distance of which changes in response to the applied voltage, and that generates second voltage information for enabling the identification of a voltage applied to a second varifocal lens 21A which is included in a second imaging unit 21 which is installed at a position enabling the imaging of a subject, and the focal distance of which changes in response to the applied voltage; and an image determining unit 40 that receives inputs of images from the first imaging unit 20 and the second imaging unit 21 and selects, from the received images, one image imaged at the focal position. The voltage control unit 30 generates, as the first voltage information, information that enables the identification of voltages among time-series voltages, the values of which change with time elapse, and generates, as the second voltage information, information that enables the identification of the voltages identified with the first voltage information as voltages applied to the second varifocal lens 21A while delayed by a predetermined time period.
