Abstract

A flicker correction apparatus for correcting a flicker component of an image signal obtained by imaging an object using an imaging device is provided. The apparatus comprises an image average calculation section for calculating an average of the image signal, a flicker frequency calculation section for calculating a flicker frequency, a flicker data extraction section for extracting flicker data using the average of the image signal and the flicker frequency, a flicker determination section for determining the presence or absence of a flicker phenomenon using the flicker data, a flicker correction amount calculation section for calculating a flicker correction amount using the flicker data, and a flicker correction section for removing the flicker component of the image data using the flicker correction amount.

Description

technical field

[0001] The present invention relates to a flicker correction device, a flicker correction method, and a recording medium storing a flicker correction program for correcting a flicker component of an image signal obtained by imaging an object with an imaging device . More specifically, the present invention relates to a flicker correction device, a flicker correction method, and a recording medium storing a flicker correction program capable of preventing the flicker phenomenon from occurring. The flicker phenomenon refers to that when an X-Y addressing scanning solid-state imaging device is used to image an object under the illumination of a fluorescent lamp, and the fluorescent lamp flickers synchronously with the frequency of the alternating current (AC) power supply, the horizontal direction appears in the image. A striped pattern of stretched dark sections alternating with light sections. Background technique
