US 5,491,769 A · Method and apparatus for variable minification of an image

Abstract

A method of shrinking an image stored in a first array including the steps of separating the first array into a plurality of rows, each row having a first plurality of data elements, each element having a value, and separately shrinking each row from a first plurality of data elements in the first array to a second plurality of data elements in a second array including the steps of correlating each of the second plurality of data elements to at least one of the first plurality of data elements, and calculating the value of each of the second plurality of data elements from the values of correlated data elements. In addition, an apparatus for shrinking an image stored in a first array including apparatus for separating the first array into a plurality of rows, each row having a first plurality of data elements, each element having a value, and apparatus for separately shrinking each row from a first plurality of data elements in the first array to a second plurality of data elements in a second array including apparatus for correlating each of the second plurality of data elements to at least one of the first plurality of data elements, and apparatus for calculating the value of each of the second plurality of data elements from the values of correlated data elements.

Dependent claims

A method of shrinking an image stored in a first array comprising the steps of:

a) separating said first array into a plurality of rows, each row having a first plurality of data elements, each of said first plurality of data elements having a value;
and
b) separately shrinking each row from the first plurality of data elements in said first array to a second plurality of data elements in a second array including the steps of:
i) sequentially associating each of said second plurality of data elements with at least one data element within only said first plurality of data elements;
and
ii) sequentially calculating the value of each of said second plurality of data elements from values of associated ones of said first plurality of data elements.
