A motion detecting apparatus in which when pixels within a search range formed of a predetermined number of pixels and pixels within a reference data block the number of which is smaller than the predetermined number of pixels in the search range, are compared on the basis of the arrangement state thereof, a processing circuit processes sums of difference absolute values of respective pixels within the reference data block and corresponding pixels within the search range formed at every search range, to thereby detect a motion state on the basis of the sums. Respective pixels within the search range are input to the processing circuit at a set time and pixels within the search range are input to the processing circuit at the set time, thereby being sequentially processed with corresponding pixels within the data block.

A motion detecting apparatus in which pixels within a search range formed of a predetermined number of pixels and pixels within a reference data block, the number of which is smaller than said predetermined number of pixels, are compared based on the arrangement thereof, comprising: processing means for processing absolute values of respective differences between pixels within said search range and pixels within the reference data block; summing means for summing processed absolute values from said processing means and producing a plurality of output sums; and comparing means for respectively comparing the output sums from said summing means to determine a minimum value to thereby detect a motion state on the basis of said compared minimum value, characterized in that said processing means includes switching selector means connected to select a number of pixels equal to the number of pixels in the reference data block from among said pixels within said search range including arbitrary dummy data for pixels outside and adjacent said search range in response to timing signals fed thereto, so that selected pixels within said search range are input to a plurality of absolute value calculating means equal in number to the number of pixels said in reference data block included in said processing means at a set time and over a number of inputs fewer in number than the number of pixels in said reference data block and selected by said selector means, thereby being sequentially processed with corresponding pixels within said reference data block.
