チ回路７でラツチした後、ＤＭＡ制御回路８を用
いてデータＲＡＭ１１へ転送すると共に、予め明
ＲＡＭ９に記憶された明データ及び暗ＲＡＭ１０
に記憶された暗データをもとに中央処理装置（Ｃ
ＰＵ）１２が補正値を演算し、かつ上記データＲ
ＡＭ１１に記憶された画像データに補正を加えて
出力ポート１３へ出力するようにしてなる画像入
力装置の補正回路。 After the image data read by the image reading means 1 is latched by the latch circuit 7, it is transferred to the data RAM 11 using the DMA control circuit 8, and the bright data previously stored in the bright RAM 9 and the dark RAM 10 are transferred.
Based on the dark data stored in the central processing unit (C
PU) 12 calculates the correction value and uses the above data R.
A correction circuit for an image input device that corrects image data stored in an AM 11 and outputs the corrected image data to an output port 13.
