Abstract
In a solid state image pickup apparatus, a read bus consists of, for instance, four lines of split buses and one line of integrated bus. This integrated bus can be connected to the four lines of split buses. Electrical connection between the integrated bus and each of the split buses is selected by a corresponding switching element. Thus, the number of switching elements connected to one split bus can be reduced and hence the capacitance of the split bus can be reduced. This allows pixel signals to be read out at a higher speed.
