Title:
IMAGE CAPTURING DEVICE, IMAGE CAPTURING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/187901
Kind Code:
A1
Abstract:
Provided are: an image capturing device that is capable of obtaining a moving image having a wide dynamic range with natural moving body motion when compositing images, which have exposure amounts made to differ by controlling the exposure time, to obtain an image having a wide dynamic range; an image capturing method; and a program. An image capturing device (1) comprises: an image capturing unit; an exposure time setting unit that sets a first exposure time and a second exposure time; an exposure control unit that repeatedly performs exposure control by setting the exposure of one frame of at least the first exposure time and the exposure of m frames of the second exposure time as one set; an image data acquisition unit (105) that acquires image data of each frame; an image data generation unit (107) that generates image data of an average frame; and a composite frame generation unit (109) that uses image data of one frame of the first exposure time and image data of the average frame to generate a composite frame having an expanded dynamic range.
