摘要： A television receiver is provided with two field memories for storing movement control signals, an OR circuit, a frame memory for storing the present and previous fields, a pair of switches controlled by a freeze signal, a switch controlled by the output signal of the OR circuit, and another switch for changing over its output signal to and from the output signal from the switch controlled by the OR circuit and the signal from the frame memory representing the present field. One frame's worth of video signals of the present field and the previous field are stored in the frame memory by a freeze signal. The signals stored in the frame memory provide a freeze picture having no multi-line dimness by virtue of using the present field and the previous field for the still picture image portion and the present field for the moving picture image portions of the present field and the previous field.
