Semiconductor sensor device having a correction circuit |
摘要 |
An imaging device includes a read circuit having a bias circuit for biasing the signal currents output from a sensor array to correct variations of the sensor array. The bias current is determined so that the number of pixel data output from the read circuit which are below or above the threshold is equal to a specified number setting for the number of pixel data. A fixed pattern noise (FPN) correction circuit determines the full scale of the FPN correction current based on the bias current.
