| titleOfInvention | Shading correction circuit and image reading apparatus |
| abstract | In a shading correction circuit of an imaging apparatus, the memory capacity of reference data for correction can be reduced. A component effective for shading correction is extracted by a valid data extraction unit from digital reference data for correcting black shading and white shading, and stored in a data holding unit. For example, the upper / lower bit selection unit 272 extracts a lower bit side for black shading and an upper bit side for white shading by a bit shift operation. When performing the shading correction on the input image data Din representing the normal image captured by the light receiving unit 140, the subtraction processing unit 252 and the normalization correction processing unit 260 are referred to by referring to the effective components read from the data holding unit 254. , White shading and black shading are corrected.
