Title: Noise reduction method
Inventor: TAKAHASHI KENJI
IPC: H04N5/378
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To attain higher sensitivity and a high S/N ratio by suppressing reset noises and 1/f noises most effectively by bisecting an outputted signal of a charge transfer element and providing a difference in frequency characteristics between a signal which passes through a delay means by specific amounts and a signal which does not pass through the means. SOLUTION: A route next to a buffer circuit 1 to receive the outputted signal of a CCD is bisected. A frequency correcting circuit 3 is provided after a delay circuit 2. The gain of the frequency characteristics of the frequency correcting circuit 3 is made lower in a low frequency range and is made higher from halfway in a high frequency range. When the characteristics is constituted of passive elements, the gain in the low frequency range is defined as <=1. The other signal is also attenuated for amounts suitable to it by an attenuator 4 to cancel the 1/f noise generated in the low frequency range. The degree to raise high frequency gain depends not only on decreasing of high frequency components in the CCD but also on the generated difference of the frequency characteristics of both circuits of the poststage.  Signal ratios at which the levels of the reset noise and the 1/f noise become maximum are made to coincide.
