摘要： An apparatus and a method of reading an image wherein processing conditions can be set up based on image data obtained by scanning image information recorded on an original to be read. The entire image reading region of a reading device with the original held therein is scanned to produce scanned data including the image data. A separator circuit compares the scanned data with given threshold data to separate the scanned data into first scanned data from the original and second scanned data from portions other than the original. An adder adds together either the number of pixels read from the first scanned data or the number of pixels read from the second scanned data along a main scanning direction for each given pitch extending in an auxiliary scanning direction, whereas another adder adds together either the number of pixels from the first scanned data or the number of pixels from the second scanned data along the main scanning direction for each given pitch extending in the main scanning direction. Each of first and second region setting-up circuits compares, for each given pitch, the number of the pixels added together along each of the main and auxiliary scanning directions with a given number of threshold pixels so as to determine an image reading region of the original, which extends in each of the main and auxiliary scanning directions.

摘要翻译：一种读取图像的装置和方法，其中可以基于通过扫描记录在要读取的原稿上的图像信息而获得的图像数据来建立处理条件。扫描具有原稿的读取装置的整个图像读取区域，以产生包括图像数据的扫描数据。分离器电路将扫描的数据与给定的阈值数据进行比较，以将来自原始部分以外的原始扫描数据和第二扫描数据的扫描数据分离成第一扫描数据。加法器将从第一扫描数据读取的像素数或从辅助扫描方向上延伸的每个给定音调沿主扫描方向读取的像素数量相加，而另一加法器将数字对于在主扫描方向上延伸的每个给定的间距，来自第一扫描数据的像素数或来自第二扫描数据的沿主扫描方向的像素数。第一和第二区域设置电路中的每一个针对每个给定的间距，将具有给定数量的阈值像素的每个主扫描方向和辅助扫描方向相加在一起的像素的数量进行比较，以便确定图像读取区域原稿在主扫描方向和辅助扫描方向上延伸。
