Image pickup device with noise data generation

摘要

An image pickup device including: a solid state image pickup element; a memory; an image pickup data generating unit for generating image pickup data through an image pickup operation of reading data from the solid state image pickup element and A/D converting the data; a first processing unit for storing the image pickup data in the memory; a noise data generating unit for generating noise data through an operation, similar to the image pickup operation in a non-exposure state, of reading data from the solid state image pickup element and A/D converting the data; and a second processing unit for generating a desired image pickup data by subtracting an average data of a plurality of noise data obtained by a plurality of repetitive operations of the noise data generating unit, from the image pickup data stored in the memory means.
