Abstract
An area designation apparatus includes an input unit for inputting coordinates of an area for image processing and a controller for determining an area on the basis of the coordinates input by the input unit. The input unit has a first input method for inputting two diagonal points of a rectangular and/or square area, and a second input method for inputting coordinates of at least three corners of a polygonal area. The controller automatically determines that the input coordinates by the input unit are entered in accordance with the first or second input method.

14. An area designation apparatus comprising:
-
means for inputting coordinates of an area for image processing; means for storing a plurality of coordinate values input by said input means; correcting means for replacing at least (1) a coordinate value currently being input by said input means or (2) a coordinate value previously input by said input means and stored in said storage means with another value in accordance with the coordinate value currently being input by said input means and other coordinate values stored in said storage means; and determining means for determining an area on the basis of the coordinate values replaced by said correcting means. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 26, 27, 37)

28. An area designation apparatus comprising:
-
means for inputting coordinates of an area for image processing; means for designating an end of an input of the coordinates of the area; and means for correcting start point coordinates or end point coordinates of the area which are input by said input means, wherein said correcting means corrects the start or end point coordinates on the basis of at least two data selected from the start point coordinates, the end point coordinates, a vector direction from the start point coordinates to input coordinates of a second point, and a vector direction from coordinates immediately preceding the end point coordinates to the end point coordinates. - View Dependent Claims (29, 30)

31. An area designation apparatus comprising:
-
means for inputting coordinates of an area for image processing, said input means having a first input method for inputting coordinates of an area having a predetermined shape, and a second input method for inputting coordinates of an area having an arbitrary shape; and control means for determining the area on the basis of the coordinates input by said input means, wherein said control means automatically discriminates whether the input method of the coordinates input by said input means is the first input method or the second input method. - View Dependent Claims (13, 32, 33, 34, 35, 36, 38)

39. An area designation apparatus comprising:
-
means for inputting coordinates of an area for image processing, said input means having a first input scheme for inputting two diagonal points of a rectangular and/or square area, and a second input scheme for inputting coordinates of at least three corners of a polygonal area; and control means for determining an area on the basis of the coordinate input by said input means, said control means automatically determining that the coordinates input by said input means are entered in accordance with the first or second input scheme, wherein said control means determines the input scheme on the basis of input coordinate values of two succeeding two points input by said input means, and wherein said control means determines an input based on the first input scheme when both differences between X- and Y-coordinate values of the succeeding two points fall outside a predetermined range and an input based on the second scheme when only one of the differences falls within the predetermined range.
