Title:
IMAGE DATA CORRECTION METHOD AND IMAGE DATA CORRECTION APPARATUS
Document Type and Number:
Japanese Patent JP2023115647
Kind Code:
A
Abstract:
To provide an image data correction method and an image data correction apparatus which can obtain more correct data of a photographed image in an imaging apparatus whose exposure amount is discretely set.SOLUTION: An image data correction method comprises steps of: acquiring a first correction coefficient γ expressing a fluctuation degree of a state of an imaging apparatus by using a reference exposure amount that is arbitrarily set and a first exposure amount being an actual exposure amount when being set to match the reference exposure amount in the imaging apparatus; correcting an imaging exposure amount that is arbitrarily set to an imaging object by using the first correction coefficient γ to decide a target exposure amount; acquiring a photographed image of the imaging object imaged with a second exposure amount different from the target exposure amount; acquiring a second correction coefficient δ expressing a difference between the second exposure amount and the target exposure amount on the basis of the target exposure amount and the second exposure amount; and correcting the acquired photographed image by using the second correction coefficient δ.SELECTED DRAWING: Figure 1
