Title:
IMAGING DEVICE, IMAGING DEVICE DRIVE METHOD, AND IMAGING DEVICE CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/171304
Kind Code:
A1
Abstract:
Provided are an imaging device, an imaging device drive method, and an imaging device control program, which improve the image quality of a photographed image and compensate for the degradation in the image quality due to production error. An imaging device (10) comprises an imaging lens (12), an image sensor (13), a lens moving mechanism (22), a ROM (37), and an intersection point position control unit (33). The lens moving mechanism (22) moves a second lens (21b) within a plane orthogonal to an optical axis (L1), and thereby moves an intersection point (An) on the image sensor (13). A LUT (38) for storing intersection points (An) in association with image quality evaluation values of images acquired by imaging at the intersection points (An), is preliminarily stored in the ROM (37). The intersection point position control unit (33): acquires the present position of intersection point (An); calculates distances between a plurality of intersection point positions stored in the LUT (38) and the present intersection point position; and selects from among the plurality of intersection point positions stored in the LUT (38) an intersection point position used for imaging where the ratio of an image quality evaluation value to a distance from the present intersection point becomes maximum.
