しセンサから連続的に一定のサイクルで画像信号
を記憶しメモリの内容を順次シフトする機能を備
えた記憶部と、所定の時点で上記記憶部に記憶さ
れている画像信号のメモリ内容と1サイクル前の
画像信号と比較して両者間の変化を検出したとき
出力する比較器と、この比較器が出力したとき上
記記憶部のメモリのシフトを中断させるとともに
上記変化の検出前、検出時、検出後の画像の内容
を上記記憶部から読み出すメモリ制御器とを備え
てなる画像処理装置。 A storage section that has a memory capacity for several frames/fields and has a function of continuously storing image signals from the sensor in a certain cycle and sequentially shifting the contents of the memory, and storing it in the storage section at a predetermined time. A comparator that compares the memory contents of the image signal currently being used with the image signal one cycle before and outputs an output when a change between the two is detected, and when this comparator outputs, interrupts the shift of the memory of the storage unit. and a memory controller that reads the contents of the image from the storage unit before, during and after the detection of the change.
