画像処理装置
Document Type and Number:
Japanese Patent JP5524133
Kind Code:
B2
Abstract:
According to embodiment, an image processing device includes a black level correcting section. The black level correcting section includes a first input restricting unit and a second input restricting unit. The second input restricting unit performs a second input restriction, having a second signal level range including a moving average as a reference, on a black level signal subjected to a first input restriction by the first input restricting unit. A correction amount calculation unit calculates a difference of an average of signal values subjected to the second input restriction and a black level standard value as a correction value to apply on an effective pixel signal.
