Filed: 1989-01-24
Abstract: PURPOSE:To thoroughly remove from a large FPN to a fine FPN by a low resolution A/D converter by analog-correcting the fixed pattern noise FPN by two stages separated into rough correction and fine correction. CONSTITUTION:The output of a solid-state image pickup element 1 is inputted to a first stage correction circuit 10A, and is converted into a digital signal by the low resolution A/D converter 8, and is taken in a memory 4 after a random noise is decreased by an adder 3. Then, the fine FPN remains as it is in the output signal of an analog subtracter 6 obtained by subtracting the output signal of the memory 4 from an original signal, but the analog subtracter 6 holds concurrently the role of an amplifier, and sends the fine FPN to a next stage correction circuit 10B as the large FPN, and the next stage correction circuit 10B removes the fine FPN by the same constitution as the first stage. Thus, from the large FPN to the fine FPN can be corrected by the low resolution A/D converter 8.
