Abstract
Abstract An image display system suitable for use in displaying, at an enlarged scale, any desired portion Si of an image presented on a picture surface of a display apparatus, or in displaying, at a reduced scale, the whole portion DFS of the image presented on the picture surface. The picture surface is divided into sub-regions arranged in m lines and n columns. Sub-region appointing numeral keys are arranged to correspond to these sub-regions, so that any desired sub-region Si is appointed by a depression of the corresponding appointing key or keys, to make the image portion in the appointed sub-region Si be enlarged and displayed over the entire area DFS of the picture surface or to make the whole part DFS of the image on the display surface be reduced and displayed in the appointed sub-region Si of the picture surface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
An image display system comprising: an image display device having an image display surface on which an image to be enlarged may be formed, said image display surface being imaginarily divided into m x n sub-regions arranged in m lines and n columns; a key input comprising a plurality of keys for use in appointing corresponding respective ones of said sub-regions; an operation unit for making the keys correspond to said respective sub-regions; and a picture processing device adapted to display, upon receipt of an output from said operation ,unit, the image of the sub-region appointed by the key display input at an enlarged scale on said imgage/ surface.
Claim 2
Dependent Claim
109 words
An image display system comprising: an image display device having an image display surface on which an image to be enlarged may be formed, said image display surface being imaginarily divided into m x n sub-regions arranged in m lines and n columns; a key input comprising a plurality of keys for use in appointing corresponding respective ones of said sub-regions; an operation unit for making the keys correspond to said respective sub-regions; and a picture processing device adapted to display, upon receipt of an output from said operation ,unit, the image of the sub-region appointed by the key display input at an enlarged scale on said imgage/ surface.
Claim 3
Dependent Claim
82 words
An image display system as claimed in claim 1, comprising a key for giving an order for display at an enlarged scale and a key for giving an order for display at a reduced scale, whereby, when an order for display at reduced scale is input through the latter key, said picture processing device will operate to reduce an image presented on said image display surface and to make the reduced image be displayed in a sub-region appointed through the key input.
Claim 4
Dependent Claim
57 words
An image display system as claimed in claim 1 or 2, wherein the number of sub-regions in the line direction and the number of sub-regions in the column direction are equal so that magnifications of m and 1/m, the latter where reduction is available, are obtained for the display at enlarged and reduced, where available, scales respectively.
Claim 5
Dependent Claim
25 words
An image display system according to any one of the preceding claims, wherein said keys for use in appointing said sub-regions bear different numerical values.
Claim 6
Dependent Claim
42 words
An image display system as claimed in claim 4, wherein the sub-region in the line i and column j on said image display surface corresponds to a sub-region appointing key represented by a numerical value [(i - 1)- m + j) .
Claim 7
Dependent Claim
50 words
. An image display system as claimed in any one of the preceding claims, wherein the picture origin point for the display at enlarged scale is calculated from data of position of the sub-region (line i, column j) obtained in accordance with the key through which the input is made.
Claim 8
Dependent Claim
44 words
An image display system as claimed in any one of the preceding claims, wherein saidimage display surface is divided into 9 sub-regions arranged in 3 lines and 3 columns, and said keys for appointing said sub-regions are constructed as a ten-key type input device.
Claim 9
Dependent Claim
54 words
An image display system as claimed in claim 7, wherein a "0" key of said ten-key type input device is used for giving an order for a display at enlarged scale, while the decimal point key of said ten-key type input device is used for giving an order for display at a reduced scale.
Claim 10
Dependent Claim
55 words
An image display system as claimed in any one of the preceding claims, wherein said operation unit is adapted to appoint, as inputs are made through sub-region appointing keys corresponding to a plurality display of adjacent sub-regions of the image / surface, an imaginary sub-region extending between or partially across said plurality of adjacent sub-regions.
Claim 11
Dependent Claim
109 words
An image display system comprising:. an image display device having an image display surface on, which an image to be reduced may be formed, said image display surface being imaginarily divided into m x n sub-regions arranged in m lines and n columns; a key input comprising a plurality of keys for us in appointing corresponding respective ones of said sub-regions; an operation unit for making the keys correspond to said respective sub-regions; and a picture processing device adapted to display, upon receipt of an output from said operation unit, the image on the image display surface at the sub-region appointed by the key input at a reduced scale.
Claim 12
Dependent Claim
109 words
An image display system comprising:. an image display device having an image display surface on, which an image to be reduced may be formed, said image display surface being imaginarily divided into m x n sub-regions arranged in m lines and n columns; a key input comprising a plurality of keys for us in appointing corresponding respective ones of said sub-regions; an operation unit for making the keys correspond to said respective sub-regions; and a picture processing device adapted to display, upon receipt of an output from said operation unit, the image on the image display surface at the sub-region appointed by the key input at a reduced scale.
