A television receiver segments a part of an image depending on image information received from a communication device and pixel information representing the number of pixels in a longitudinal direction and a lateral direction of the image. The television receiver judges a size between the number of pixels in the longitudinal direction and that in the lateral direction in the pixel information, and when it is judged that the number of pixels in the longitudinal direction is larger than that in the lateral direction, displays two screens in which the segmented image and another image are juxtaposed on a display unit. Meanwhile, when it is judged that the number of pixels in the longitudinal direction is not larger than that in the lateral direction, the television receiver receives a signal designating the number of screens to be displayed on the display unit and displays the two screens in which the segmented image and another image are juxtaposed or one screen of the segmented image on the display unit depending on the received signal.
