A television receiver and apparatus which includes a field memory which is capable of storing a video signal during a first period of time and includes a control for controlling the writing of the video signal in the image and also for displaying the stored video signal on the video screen intermittently.

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide an improved television apparatus which can remove the defects encountered with the prior art television apparatus.
More specifically, it is an object of the present invention to provide a television apparatus which can prevent an image displayed in a strobe-action-fashion from being disturbed even when an incoming video signal is switched in the strobe-display state.
Another object of the present invention is to provide a television apparatus which can prevent the display of the image from being interrupted.
Still another object of the present invention is to provide a television apparatus which can prevent the strobe-display from being stopped.
A further object of the present invention is to provide a television apparatus which can prevent an image, displayed in the strobe-action-fashion, from being shifted in the vertical direction.
According to an aspect of the present invention, there is provided a television apparatus comprising: (a) switching means for selecting a plurality of input video signals; (b) memory means for storing one of said plurality of input video signals selected by said switching means; (c) first control means for controlling reading and writing timings of said video signal at said memory means, said first control means generating control signals composed of; a first control signal for writing a still image of said video signal in said memory means within a first period of time at every predetermined period; a second control signal for stopping the writing of said still image of said video signal in said memory means; and a third control signal for repeatedly reading said still image from said memory means over a second period of time which is longer than said first period of time; (d) second control means for controlling said switching means so as to generate a switching motion within said second period of time when said switching means receives a signal for selecting said video signal
