Title:
画像処理装置、画像処理方法および画像処理プログラム
Document Type and Number:
Japanese Patent JP4801186
Kind Code:
B2
Abstract:
An image processing device includes: processing pixel group determination unit that determines a to-be-processed pixel group from a plurality of frame images of picture signals input based on a first predetermined rule and that determines a processed pixel group from the processed frame image stored based on a second predetermined rule; frequency component processing unit that extracts at least a temporal frequency component from the to-be-processed pixel group and the processed pixel group, that executes predetermined coefficient processing on a temporal high-frequency component of the temporal frequency component and that acquires the executed to-be-processed pixel group; processing completion frame generation unit that generates a processing completion frame image from the executed to-be-processed pixel group; and image output unit that outputs the processing completion frame image and that stores the processing completion frame image in the processed frame storage unit, in which the frequency component processing unit prevents the predetermined coefficient processing from being executed on a component having low sensitivity in visual characteristic included in the temporal high-frequency component.
