PROBLEM TO BE SOLVED: To obtain a video signal processing circuit whose circuit scale and power consumption can be reduced. SOLUTION: This video signal processing circuit is constituted of a CCD 21, a clamp and hold circuit 22, an A/D converter 23, a driving circuit 24, and a timing generating circuit 25. Thus, the video signal processing circuit is constituted by using not a correlative double sampling circuit using plural amplifiers, buffers, and switches or the like constituting a conventional video signal processing circuit but the clamp and hold circuit so that an equivalent video signal noise removing function can be realized in a smaller circuit scale than that of the conventional video signal processing circuit.
