Interactive image display

Claim 1

A method of interactively controlling the display of an image on a monitor screen, the image being stored in the form of digital data defining the colour content of pixels of the image, the method comprising: i) displaying a representation of said image on said monitor screen; ii) selecting a first point on said image and a first point on said monitor screen at which said first image point is to be located; iii) selecting with a cursor a second point on said image; iv) moving said cursor relative to said monitor screen; v) and during said cursor movement repeatedly adjusting the representation of said image displayed in accordance with one or more predetermined algorithms so that said second image point remains coincident with said cursor position defining a second screen point while said first image point is fixed at said first screen point, wherein said image is displayed such that a relative disposition of displayed image points is adjusted so as to be similar to an adjustment in relative disposition between said first and second screen points.

Claim 2

A method of interactively controlling the display of an image on a monitor screen, the image being stored in the form of digital data defining the colour content of pixels of the image, the method comprising: i) displaying a representation of said image on said monitor screen; ii) selecting a first point on said image and a first point on said monitor screen at which said first image point is to be located; iii) selecting with a cursor a second point on said image; iv) moving said cursor relative to said monitor screen; v) and during said cursor movement repeatedly adjusting the representation of said image displayed in accordance with one or more predetermined algorithms so that said second image point remains coincident with said cursor position defining a second screen point while said first image point is fixed at said first screen point, wherein said image is displayed such that a relative disposition of displayed image points is adjusted so as to be similar to an adjustment in relative disposition between said first and second screen points.

Claim 6

An apparatus for interactively controlling the display of an image on a monitor screen, the image being stored in the form of digital data defining the colour content of pixels of the image, the apparatus comprising: a monitor having a monitor screen; a first store for storing said digital data defining said image; processing means; operator actuable control means to enable an operator to move a cursor relative to an image displayed on said monitor screen by said processing means; and a second store for storing the digital representation of said image to be displayed on said monitor screen, said processing means being responsive to signals from said operator actuable control means to cause a modified form of said image to be stored in said second store, said modified form of said image being generated by applying one or more of the predetermined algorithms to data from said first store, wherein said apparatus is adapted to carry out the steps of i) displaying a representation of said image on said monitor screen; ii) selecting a first point on said image and a first point on said monitor screen at which said first image point is to be located; iii) selecting with a cursor a second point on said image; iv) moving said cursor relative to said monitor screen; v) and during said cursor movement repeatedly adjusting the representation of said image displayed in accordance with one or more predetermined algorithms so that said second image point remains coincident with said cursor position defining a second screen point while said first image point is fixed at said first screen point, wherein said image is displayed such that a relative disposition of displayed image points is adjusted so as to be similar to an adjustment in relative disposition between said first and second screen points.

Claim 7

An apparatus for interactively controlling the display of an image on a monitor screen, the image being stored in the form of digital data defining the colour content of pixels of the image, the apparatus comprising: a monitor having a monitor screen; a first store for storing said digital data defining said image; processing means; operator actuable control means to enable an operator to move a cursor relative to an image displayed on said monitor screen by said processing means; and a second store for storing the digital representation of said image to be displayed on said monitor screen, said processing means being responsive to signals from said operator actuable control means to cause a modified form of said image to be stored in said second store, said modified form of said image being generated by applying one or more of the predetermined algorithms to data from said first store, wherein said apparatus is adapted to carry out the steps of i) displaying a representation of said image on said monitor screen; ii) selecting a first point on said image and a first point on said monitor screen at which said first image point is to be located; iii) selecting with a cursor a second point on said image; iv) moving said cursor relative to said monitor screen; v) and during said cursor movement repeatedly adjusting the representation of said image displayed in accordance with one or more predetermined algorithms so that said second image point remains coincident with said cursor position defining a second screen point while said first image point is fixed at said first screen point, wherein said image is displayed such that a relative disposition of displayed image points is adjusted so as to be similar to an adjustment in relative disposition between said first and second screen points.
