IMAGE PROCESSING APPARATUS AND RADIOGRAPHIC APPARATUS HAVING THE SAME

摘要

The disclosure can achieve provision of an image processing apparatus that ensures to remove a noise component from an image by determining presence or absence of noise with accuracy to obtain an image with excellent visibility. That is, the image processing apparatus performs identification of the noise component with the number of surrounding pixels each having a pixel value approximate to that of the target pixel. This achieves accurate identification of the target pixel, having an extremely different pixel value from the pixel values of the surrounding pixels, as the noise component. The disclosure achieves noise identification faithfully representing poor visibility. Such the identification of the noise component causes provision of an image processing apparatus that allows generation of a processed image with the noise components accurately removed therefrom.

主权项

1. An image processing apparatus for processing an image obtained by fluoroscopying a subject, comprising:
a noise identifying device configured for a target pixel image to search analogous pixels which have pixel values approximate to that of the target pixel from surrounding pixels being around the target pixel, and to count the analogous pixels, thereby identifying the target pixel as the noise component when the number of the analogous pixels is an integer value of first specified number or more, and a pixel-value changing device configured to change a pixel value of a pixel of the noise component in the image in accordance with identified result by the noise identifying device, and the noise identifying device performs further noise identification again to the noise identification performed target pixel with adding the surrounding pixels, thereby finally identifying the target pixel, identified as the noise component through both of the noise identification and the further noise identification, as a noise component.
