ABSTRACT:
A picture combining apparatus for concurrently using a single shooting television camera to pick up still pictures such as titles. In the picture combining apparatus, the level of a luminance signal in a still picture signal generated from the television camera is compared with a threshold level to generate a binary signal corresponding to the difference therebetween and the binary signal is stored in a memory. At a given time during the shooting of a background the content of the memory is read so that the binary signal is provided with a particular color or luminance level and is superimposed on a background picture signal from the camera. Thus, the camera generates an output signal corresponding to a picture comprising the still picture superimposed on the background.
