| 摘要 | The present invention provides an apparatus for processing image data obtained by reading a document and a background image outside the document, and method of controlling the apparatus. The apparatus determines a degree of similarity between a color of the background image and a color of a marginal region of the document from the image data, sets a region extraction parameter based on the determined degree of similarity, and determines a document region by using the region extraction parameter from the image data. | ||

| 主权项 | 1. An apparatus for processing image data obtained by reading a document and a background image outside the document, the apparatus comprising: one or more processors; a memory configured to store program data executed by the one or more processors; a similarity determination section configured to determine a degree of similarity between a color of the background image and a color of a marginal region of the document from the image data; a region extraction parameter section configured to set a region extraction parameter based on the degree of similarity determined by the similarity determination unit; and a document determination section configured to determine a document region by using the region extraction parameter from the image data. | ||
