摘要： An image copier according to the invention comprises a scanner for reading an image and a printer for forming an image on sheet, and the scanner includes a document table for positioning an original document from which an image is to be read; a document holding cover holding the original document on the original document table and having a light-emitting element for detecting the size of an original document which emits light when the size of the original document is detected, a light source for irradiating the original document with light when an image on the original document is read, a light-receiving element for image reading which receives reflected light from the original document, a controller for the light-emitting element for detecting the size of an original document which controls the light-emitting element for detecting the thickness of the original document, a specific region determination unit for identifying a specific region based on the numbers of pixels in a main scanning direction and a sub scanning direction of image data, and a background correction unit for performing a process of correcting the background of an image which has been read. In the image copier according to the invention, see-through copying of the bottom side can be suppressed by performing a background correction process after an image is read without blocking a sensor hole of a sensor for detecting the size of the original document from light.
摘要翻译：根据本发明的图像复印机包括用于读取图像的扫描仪和用于在纸上形成图像的打印机，并且扫描仪包括用于定位要从中读取图像的原稿的原稿台; 原稿保持盖，将原稿保持在原稿台上，并具有发光元件，用于检测当检测到原稿的尺寸时发光的原稿的尺寸;用于将原稿的照射光源读取原稿上的图像时的光，用于接收来自原始文档的反射光的图像读取用光接收元件，用于检测控制发光的原稿的原稿尺寸的发光元件的控制器用于检测原稿厚度的元件，用于基于图像数据的主扫描方向和副扫描方向上的像素数识别特定区域的特定区域确定单元，以及用于执行图像数据的处理的背景校正单元校正已读取的图像的背景。在根据本发明的图像复印机中，通过在读取图像之后执行背景校正处理可以抑制底侧的透视复制，而不会阻挡用于检测原稿尺寸的传感器的传感器孔的光。
