Abstract
Abstract An image processing apparatus capable of detecting (1) the size or position of the original on the table, and/or (2) the size or position of an information portion of the original. The apparatus includes an original supporting table for supporting an original. The original has an information portion and a non-information portion. Reading apparatus is provided for reading an area of the table including the original placed on the table, and for generating image data corresponding to the read area and the read original. First detector circuitry is included for detecting the position or size of the original on the table based on the image data from the reading apparatus. Second detector circuitry is included for detecting the position or the size of the information portion of the original based on the image data from the reading apparatus.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
98 words
An image processing apparatus comprising: an original supporting table for supporting an original, the original having an information portion and a non-information portion; reading means for reading an area of said table including an area on which the original is placed, and for generating image data corresponding to the read area; first detector means for detecting the position of the original on said table based on image data from said reading means; and second detector means for detecting the position or the size of the information portion of the original based on image data from said reading means.
Claim 2
Dependent Claim
98 words
An image processing apparatus comprising: an original supporting table for supporting an original, the original having an information portion and a non-information portion; reading means for reading an area of said table including an area on which the original is placed, and for generating image data corresponding to the read area; first detector means for detecting the position of the original on said table based on image data from said reading means; and second detector means for detecting the position or the size of the information portion of the original based on image data from said reading means.
Claim 3
Dependent Claim
76 words
An image processing apparatus according to claim 1, wherein the position of the original is detected by said first detector means based on image data from the reading means generated during a first reading of the area of the table, and wherein the position or size of the information portion is detected by said second detector means based on image data from the reading means generated during a second reading of the area of the table.
Claim 4
Dependent Claim
32 words
An image processing apparatus according to claim 1, further comprising process means for processing image data from said reading means, based on the result of the detection by said second detector means.
Claim 5
Dependent Claim
133 words
An image processing apparatus comprising: an original supporting table for supporting an original, said original having an information portion and a non-information portion; reading means for reading an area of the table including and area on which the original is placed and for generating image data corresponding to the read area; first detector means for detecting the position or size of the original on said table based on image data from said reading means; second detector means for detecting the position or size of the information portion of said original based on image data from said reading means; and process means for processing image data from said reading means based on either the result of the detection by said first detector means or the result of the detection by said second detector means.
Claim 6
Dependent Claim
133 words
