ABSTRACT:
An apparatus for detecting moving and unmoving regions in a moving image includes three memories for storing differentiation results of respective pixels in an x component, a y component, and a time component from two moving image data which are temporally successive. A first calculator reads out values of pixels near respective pixels in arbitrary two of the three memories, and calculates all quantities of multiplication/addition between the pixels. A second calculator calculates a value equivalent to a covariance determinant of vectors of an x component, a y component, and a time component from six results of the multiplication/addition. A third calculator calculates a multiplication between a time differentiation energy and a square of a spatial differentiation energy from results of the calculation of the second calculator and the pixel data values stored in the memories. A judgment device calculates a ratio of a result of an addition between an output data from the third calculator and an error energy.
