The motion vector detecting device with a self-testing function includes an operation circuit that calculates, by block matching, estimation values between a template block and respective image blocks in a search area, an input circuit including a select circuit that selects either data for testing or data being processed, for application to the operation circuit, a comparing circuit that detects, when the data being processed is supplied to the operation circuit, a motion vector of the template block based on the calculated results of the operation circuit, an operation result compressing circuit that performs, when the data for testing is applied to the operation circuit, a predetermined operation on the calculated results of the operation circuit to compress the results for outputting; and a test control circuit that controls data selection of the select circuit.
