<P>PROBLEM TO BE SOLVED: To provide a noise reduction circuit capable of suppressing noise without the need for provision of an expensive frame memory at the outside of the circuit. <P>SOLUTION: The noise reduction circuit includes a plurality of electric charge storage means 2a to 2n and a plurality of switch means 1a to 1n. After the electric charge amount in response to a signal including a noise component is stored in the electric charge storage means 2a to 2n, the electric charge storage means 2a to 2n are connected in parallel with each other by conducting the switch means 1a to 1n. Thus, the circuit provides an output of a signal corresponding to an average of the electric charge amount stored in the electric charge storage means 2a to 2n. <P>COPYRIGHT: (C)2007,JPO&INPIT |
