PROBLEM TO BE SOLVED: To realize main scanning conversion of high image quality wherein deterioration of image is restrained when a movement vector different from actual movement is detected in movement compensation type scanning conversion. SOLUTION: This main scanning conversion equipment 1 for converting an interlace signal to a sequential scanning image signal is provided with an interpolation part 3 for a still image which produces an interpolation signal between fields, an interpolation part 2 for a moving image which produces an interpolation signal in a field, a movement vector detecting part 4 for detecting a movement vector, a reinforcement signal producing part 5 for producing a reinforcement signal, a reinforcement signal adding part 6 which produces a reinforced interpolation signal in a field by adding the reinforcement signal to the interpolation signal in a field, a movement detecting part 7 for detecting moving amount, a movement adaptation adding part 8 which produces a movement adapting interpolation signal by switching over an adding ratio between the interpolation signal in a field and the interpolation signal between fields in accordance with the moving amount, and double-speed process part 9 which performs time axis compression and time series alignment change of the interlace signal and the movement adapting interpolation signal.
