【発明の名称】画像走査装置およびその補正方法
Document Type and Number:
Japanese Patent JP2761406
Kind Code:
B2
Abstract:
Method and apparatus for a wide range of correction of photosite offset and gain. Each photosite is provided with a correction value for offset and gain based on measured light intensity value. Each photosite correction value is also provided with an attribute value which is detected by a decoder (208) and indicates (i) whether the correction values are to be used as stored (in a memory 200); (ii) whether a shift of the values (by shift means 210a, 210b) is appropriate, in accordance with a shift value stored in a shift memory (212); or (iii) whether the photosite is non-correctable, and accordingly requires the implementation by an output selector (214) of a bad pixel routine comprising the substitution of an approximated photosite response derived at a bad pixel correction device (218).
