Abstract
A video data conversion apparatus can convert inputted video data in a predetermined scanning format into video data in another scanning format. The inputted video data in the predetermined scanning format is video data at 60 fields per second in a 4:2:2:2 format. The video data in the 4:2:2:2 format is video data in a format where four fields generated from one original image, two fields generated from a next original image, two fields generated from a further next original image, and two fields generated from a further next original image appear periodically in this order. The video data conversion apparatus includes a conversion unit operable to convert the inputted video data into video data at 60 frames per second in a 3:2 pulldown format.
