撮像装置及び距離計測方法
Document Type and Number:
Japanese Patent JP5832424
Kind Code:
B2
Abstract:
An imaging apparatus (10) includes: an imaging unit (11); a focal range control unit (12) configured to cause the imaging unit (11) to capture a first image (31a) and a second image (31b) which have mutually different focal ranges, changing a focal position of the imaging unit (11); a reference image generation unit (13) configured to generate, using the first image (31a) and the second image (31b), a reference image (32) to be used as a blur standard; and a distance measurement unit (14) configured to measure a distance to the subject based on a difference in blur degrees between the reference image (32) and each of the first image (31a) and the second image (31b). The focal ranges of the first image (31a) and the second image (31b) are independent of each other, and an out-of-focus space is provided between the focal ranges.
