PURPOSE:To avoid the generation of linear flaws on an image pickup screen, by connecting a spare vertical shift register having a function to deliver the signals to the same line of a vertical gate line with the same timing to the other end of the vertical gate line of each picture element. CONSTITUTION:A vertical shift register 10' is connected to the other end of each of vertical gate lines 6a, 6b and 6c which are connected to a vertical shift register 10. The register 10' has an exactly equal function to the register 10 and is driven with the same timing. In such constitution, the left and right registers 10 and 10' are driven simultaneously and with the same timing when a solid state image pickup element 1 works. Thus the pulses are applied simultaneously and with the same timing to the lines 6a, 6b and 6c from both registers 10 and 10'. Accordingly if the line 6b has a disconnection, all signals at and after a picture element 4' connected to the gate line 6b' can be read owing to the pulse applied from the register 10'. Thus no linear flaw is observed on the image pickup screen. |
