    Abstract: During a sheet-through operation, for a first original, a shading operation is performed to acquire white data and a light-quantity measuring operation is performed to acquire a reference value. For subsequent originals, only the light-quantity measuring operation is performed to acquire a subsequent light quantity. If the reference value and the subsequent light quantity differ greatly, the shading operation is performed at this time point to acquire new white data. The sheet-through operation is not stopped when the shading operation is not performed and the sheet-through operation is stopped when the shading operation is performed.

    Abstract translation: 在直通操作期间,对于第一原稿,执行阴影操作以获取白色数据,并执行光量测量操作以获取参考值。 对于随后的原稿,仅进行光量测量操作以获取随后的光量。 如果参考值和后续光量差异很大,则在该时间点执行阴影操作以获取新的白色数据。 当不执行阴影操作并且当执行阴影操作时,直通操作停止时,片刻通过操作不停止。
