    • The present invention aims to prevent a problem that an image on a document sheet is erased due to misdetection of a line-shaped noise. A copy machine 1 compares RGB values of a target pixel with averaged RGB values (Step S103). If only one of the RGB values has a difference that is greater than a prescribed value Ref2 (Step S103: YES), the copy machine 1 extracts the target pixel as a line-shaped noise pixel, and moves to a line-shaped noise correction (Step S108) while holding the address of the target pixel in a line-shaped noise address storing area 49b. If two of the RGB values have differences (Step S103: NO, Step S104: YES) and a difference between these two of the RGB values is no greater than a prescribed value Ref3 (Step S105: YES), the copy machine 1 extracts the target pixel as a line-shaped noise pixel, and moves to the line-shaped noise correction (Step S108) while holding the address of the target pixel in the line-shaped noise address storing area 49b.

    • Two subject images shot by an imaging section before real exposure are captured, and the difference between data is obtained for each corresponding pixels of the subject images by an interframe difference calculation section. The difference is compared with a threshold value by a threshold value comparison section, the pixels of levels not less than the threshold value level are extracted as a non-correlated portion, and the ratio of the area of the non-correlated portion to all the detected pixels is obtained by a non-correlated portion area calculation section. When the ratio of the area of the non-correlated portion is high, it is determined that the subject movement is large, so that a speed priority program line is selected by an exposure calculation block and the exposure time is set to be shorter than the normal exposure time, thereby preventing subject image blur.
