Abstract
Abstract An apparatus and the method embodied therein for increasing the resolution of a data image received and stored in binary form. The method interrogates each data bit with respect to two or more data bits which surround the data bit being interrogated and expands the interrogated data bit into a plurality of new data bits. The apparatus comprises a first storage means, an expander, and a second storage means for storing the newly generated information.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
174 words
A method, for increasing the resolution of a system for producing images, said images being stored as a data image comprising a matrix of first binary bits of first and second binary values, each first binary bit representing an area of the physical image to be displayed, comprising the steps of: expanding each said first binary bits of a first value into k second binary bits of said first value and each said first binary bits of a second value into k third binary bits, the value of each of said k third binary bits being dependent on the value of said first binary bits adjacent each of said binary bits of a second value; partitioning each of said areas of said physical image represented by each first binary bits into k sections; and displaying each of said k sections of said areas of said physical image as a function of said k second and k third binary bits whereby the number of binary bits of said data image is increased by factor k.
Claim 2
Independent Claim
174 words
A method, for increasing the resolution of a system for producing images, said images being stored as a data image comprising a matrix of first binary bits of first and second binary values, each first binary bit representing an area of the physical image to be displayed, comprising the steps of: expanding each said first binary bits of a first value into k second binary bits of said first value and each said first binary bits of a second value into k third binary bits, the value of each of said k third binary bits being dependent on the value of said first binary bits adjacent each of said binary bits of a second value; partitioning each of said areas of said physical image represented by each first binary bits into k sections; and displaying each of said k sections of said areas of said physical image as a function of said k second and k third binary bits whereby the number of binary bits of said data image is increased by factor k.
Claim 3
Dependent Claim
22 words
A method for increasing resolution as set forth in claim 1 wherein the step of partitioning forms four sections of equal area.
Claim 4
Dependent Claim
20 words
A method for increasing resolution as set forth in claim 2 wherein the step of partitioning forms four square sections.
Claim 5
Dependent Claim
20 words
A method for increasing resolution as set forth in claim 2 wherein the step of partitioning forms four triangular sections.
Claim 6
Dependent Claim
95 words
A method for increasing resolution as set forth in claim 3 wherein the step of expanding each said first binary bit of a second value further comprises the steps of: storing a first binary bit associated with location position P(n,m); storing first binary bits associated with decision position P(n-1,m-1), P(n-1,m), P(n-1,m+1), P(n,m-1), P(n,m+1), P(n+1,m-1), P(n+1,m) and P(n+1,m+1); and expanding said stored first binary bits associated with location position into said four third binary bits, the value of each of said four third binary bits being a function of the binary values of said stored positions.
Claim 7
Dependent Claim
146 words
A method for increasing the resolution as set forth in claim 5 wherein the step of expanding further comprises the steps of: first assigning a first binary value to said four third binary bits which are bounded on two sides by first and second decision positions having a first binary value; second assigning a first binary value to said four third binary bits which are bounded on one side by a first assigned four third binary bit and on a second side by either of said first or second decision position, if and only if said firSt or second decision position is further bounded by a third decision position having a first binary value which is not common to said first and second decision positions; and third assigning a second binary value to the remaining said four third binary bits of said first and second assigning.
Claim 8
Dependent Claim
92 words
A method for increasing the resolution as set forth in claim 4 wherein the step of second expanding further comprises the steps of: storing a first binary bit associated with a location position P(n, m); storing first binary bits associated with decision positions P(n-1, m), P(n, m+1), P(n+1, m) and P(n, m-1); and expanding said stored first binary bits associated with the location positions into said four third binary bits, the value of each of said four third binary bits being a function of the binary values of said stored decision positions.
Claim 9
Dependent Claim
100 words
A method for increasing the resolution as set forth in claim 7 wherein the step of expanding further comprises the steps of: first assigning a first binary value to said four third binary bits which are bounded on a first side by a decision position having a first binary value and bounded on a second side by another one of said four third binary bits which is also bounded on one side by a decision position having a first binary value; and said assigning a second binary value to the remaining of four third binary bits from said first assigning.
Claim 10
Independent Claim
163 words
An apparatus, for increasing the resolution of a data image stored in an image display system, comprising: a first storage means for storing a portion of said stored data image, said portion comprising first data bits and second data bits, said second data bits being the surrounding data bits of said first data bits within said data image; an expanding means connected to said first storage means for expanding each said first data bits into k third data bits, the value of each of said k third data bits being a function of the value of said first data bit and the values of selected said second data bits; and second storage means connected to said expanding means for storing said k third data bits, the output of said storage means making the values of said k third data bit available to said image display system whereby the data image stored in said image display system has been increased by a factor k.
Claim 11
Independent Claim
163 words
An apparatus, for increasing the resolution of a data image stored in an image display system, comprising: a first storage means for storing a portion of said stored data image, said portion comprising first data bits and second data bits, said second data bits being the surrounding data bits of said first data bits within said data image; an expanding means connected to said first storage means for expanding each said first data bits into k third data bits, the value of each of said k third data bits being a function of the value of said first data bit and the values of selected said second data bits; and second storage means connected to said expanding means for storing said k third data bits, the output of said storage means making the values of said k third data bit available to said image display system whereby the data image stored in said image display system has been increased by a factor k.
