IMAGING DEVICE, FOCUS CONTROL METHOD OF THE SAME AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To cause the same object to be imaged to be excellently focused in a compound-eye imaging device even in cases where mechanical and electrical changes with the passage of time of focal distances in lenses occur or where imaging sections are provided with zoom lenses in which the focal distances are dynamically changed.

SOLUTION: An imaging device comprises: a definition calculating section for individually calculating definition of each image obtained by each of two imaging sections that are provided with focus lenses and are disposed side by side from a contrast value of the image included in a calculation region set for each image; and a controlling section for controlling a position of the focus lens with which each imaging section is provided such that the definition calculated becomes maximum. The imaging device further comprises: a parallax calculating section for calculating a parallax between two images individually obtained by individual imaging sections; and a correcting section for correcting the calculation region of one image on the basis of the parallax calculated by the parallax calculating section.
