PROBLEM TO BE SOLVED: To provide a motion adaptive progressive scanning conversion apparatus capable of preventing image quality deterioration in progressive scanning conversion. SOLUTION: A progressive scanning conversion apparatus 1 comprises a field delay unit 10, a field delay unit 11, a motion detecting unit 12, an inter-field zero-vector correlation detecting unit 13, a motion detection correcting unit 14, a moving image interpolation pixel generating unit 15, a still image interpolation pixel generating unit 16, an interpolation pixel mixing generating unit, and a time-sequential conversion unit 18. The inter-field zero vector correlation detecting unit 13 detects correlation of small regions obtained by dividing an entire screen at the same screen positions respectively in a current field and a preceding field or in the current field and a following field and when the correlation detected by the inter-field zero vector correlation detecting unit is lower, the motion detection correcting unit 14 corrects output of the motion detecting unit 12 to be closer to a moving image determination.
