PURPOSE:To obtain an in-chromakey which uses the composite color picture signal as a subject without requiring the three color primaries R, G and B, by sampling a color picture and then handling the picture as an array of picture element unit. CONSTITUTION:The picture signal V1 supplied from the camera C1 which photographs the background of a composite picture is mixed with the signal V2' obtained by processing the picture signal V2 supplied from the camera C2 that shoots an object through a mixer MX on basis of the keying pulse given from the keying pulse generator 9. Thus an output is generated. The cursor that is the output of the cursor signal generator 13 is generated on the color picture monitor M that monitors the picture signal V2. The position of the cursor is controlled from outside to designate the sampling color region in the signal V2. Then the desired synthetic picture is obtained from the pictures of cameras C1 and C2. |
