There is provided an image processing apparatus (method) including an input means (step) for inputting a continuous image signal, a detection means (step) for detecting a frame change in an image by comparing the image signal input by the input means (step) with a reference image signal, and a storage means (step) for updating/storing the image signal input by the input means (step) as the reference image signal in units of frames in accordance with an output from the detection means (step). There is provided an image processing apparatus (method) including an input means (step) for inputting a continuous image signal, a change component extraction means (step) for extracting change components between images by comparing the image signal input by the input means (step) with a reference image signal, an erroneous extraction correction means (step) for detecting and removing an erroneously extracted change component from the change components extracted by the change component extraction means (step), and an image change discrimination means (step) for discriminating an image change in the image signal on the basis of the change component corrected by the erroneous extraction correction means (step).
