Abstract
Abstract Disclosed is a picture processing apparatus comprising image pickup for taking a picture of an object and outputting picture information in the interlace system, picture information storage device for storing a first field picture information and a second field picture information outputted from the image pickup, speed detecting apparatus for detecting a moving speed of the object picked up by the image pickup, read-address correction circuitry for relatively correcting the address and for reading the first and second field picture information stored in the picture information storage device in accordance with the moving speed of the object detected by the speed detecting apparatus, and picture composition circuitry for composing the first field picture information and the second field picture information outputted from the picture information storage device after address correction. This enables obtaining an accurate frame picture without discrepancy owing to the moving speed of the moving object between field pictures.
