A solid state imaging device compatible with first and second television systems having different scanning line numbers and different aspect ratios includes a first imaging area having a number of picture elements corresponding to the scanning line number of the first system and a second sub-area having a number of picture elements corresponding to the difference in scanning line numbers of the two systems. When using the imaging device with the first system, signal charges in the picture elements in the first area are read out in a predetermined period while the signal charges in the sub-area are eliminated in a second predetermined period. When using the imaging device with the second system, a lens imaging device converts the aspect ratio of the second system to the aspect ratio of the first system.
