Title:
IMAGING CONTROL DEVICE, IMAGING DEVICE, IMAGING CONTROL METHOD, AND IMAGING CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/181515
Kind Code:
A1
Abstract:
The present invention provides an imaging control device, an imaging device, an imaging control method, and an imaging control program capable of increasing focusing accuracy. A system control unit (11) acquires brightness data for each segment area AF1 – AF3 in a target focus area defined for a first captured image signal obtained by capturing a subject; controls, on the basis of a value defined for brightness determined by the brightness of these segment areas, the imaging condition of an imaging element (5) so that the brightness of a lowest-brightness segment area exhibiting the lowest brightness is a defined value; and controls focusing with a focus lens on the basis of the target focus area defined in the captured image signal obtained by capturing the subject after controlling the transmittance of areas corresponding to other segment areas excluding the lowest-brightness segment area in a variable ND filter (3) to reduce the brightness of other segment areas.
