Title:
IMAGING CONTROL DEVICE, IMAGING DEVICE, IMAGING CONTROL METHOD, AND IMAGING CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/181299
Kind Code:
A1
Abstract:
Provided are an imaging control device, an imaging device, an imaging control method, and an imaging control program with which it is possible to accurately establish a dark-time image signal. A control unit (11A) causes an imaging element (5) that captures an image of a subject through a focus lens and a variable-ND filter (3) to perform first imaging for recording, and furthermore to perform multiple sessions of second imaging for establishing a dark-time image signal. A dark-time image signal acquisition unit (11B) establishes a dark-time image signal on the basis of a plurality of captured image signals obtained from the imaging element (5) by the multiple sessions of second imaging. The control unit (11A) controls the variable-ND filter (3) and causes the second imaging to be performed in each of a plurality of exposure states in which the quantity of light entering the imaging element (5) is greater than (0) and which are different from each other, and furthermore controls the focus lens and obtains a de-focused state during the second imaging.
