Disclosed is an image processing apparatus, including: an averaging processing unit to periodically execute an averaging processing of applying an averaging pattern to a processing target image and replacing each pixel value in a pixel group corresponding to the averaging pattern with an average value of the pixel values; a resolution converting unit to perform a resolution converting processing to the processing target image, the resolution converting processing converting a resolution R1 of the processing target image into a resolution R2 (R1<R2); a screen processing unit to perform a screen processing to a processed image which has been processed by the averaging processing, the screen processing applying a screen pattern to the processed image at the same or almost the same period as that of the averaging processing; and a control unit to control the averaging processing unit, the resolution converting unit and the screen processing unit such that the averaging processing, the resolution converting processing and the screen processing are performed in this order to the processing target image. |
