A double-picture type television receiver for displaying two different pictures on its screen. The television receiver is equipped with an image memory having a capacity required for storing a child picture signal to be inputted, the child picture signal to be stored being for one picture and a line memory coupled in series to an output of the image memory. Also included are multipliers, one being directly coupled to the output of the image memory for multiplying the output of the image memory by a predetermined coefficient and the other being coupled to outputs of the line memory for multiplying the outputs of the line memory by a predetermined coefficient. An adder calculates the sum of outputs of the multipliers and outputs the sum signal as a child picture signal. A switching device is responsive to a parent picture signal inputted from an external circuit and further to the output of the adder for performing a switching operation between the parent picture signal and the output of the adder with respect to a display device.
