Image capturing apparatus, image capturing method, and program

摘要

An image capturing apparatus extracts frequency components from image data of a newly captured photograph, divides them into divided sections, compares the frequency components of each of the divided sections of the newly captured photograph and frequency components of corresponding divided sections of a database, obtains a maximum vicinity area, and replaces first extraction components, which are a portion of components extracted from among frequency components outside the maximum vicinity area of each of the divided sections of the newly captured photograph, with second extraction components, which are a portion of components extracted from among frequency components outside the maximum vicinity area of corresponding divided sections of the database, at positions of the frequency components of the newly captured photograph corresponding to the positions of the second extraction components.

主权项

1. An image capturing apparatus comprising:
a photograph capturing section that captures a photograph to acquire image data; a database in which a predetermined frequency component of at least one photograph captured in the past by the photograph capturing section is stored; a frequency component extracting section that extracts the predetermined frequency component from image data of a photograph that is newly captured by the photograph capturing section; a region dividing section that divides a frequency component of the newly captured photograph into two or more divided regions; a maximum neighboring region calculating section that collates a frequency component in each divided region of the newly captured photograph and a frequency component in each corresponding divided region in the database, and calculates a maximum neighboring region where a total number of coincidences of frequency components included in respective frequency components is a maximum; and a component replacing section that replaces a partial first extraction component extracted from a frequency component outside the maximum neighboring region of each divided region of the newly captured photograph with a partial second extraction component extracted from a frequency component outside the maximum neighboring region of each corresponding divided region in the database, at a position of the frequency component in the newly captured photograph corresponding to a position of the partial second extraction component.
