Image recognition device and an image recognition method

Claim 1

A device for extracting a feature of an input image, said device comprising: a light source for emitting a light; first display means having M by N elements for displaying a first extracted pattern from said input image, where M and N are natural numbers; second display means having approximately M 2 by N 2 elements for displaying a direction based pattern representing, for each of a plurality of particular elements on said first extracted pattern, a plurality of elements positioned in a specified range of direction with regard to the particular element on said first extracted pattern displayed on said first display means; third display means having approximately M 2 by N 2 elements for displaying a multi-image pattern obtained by multiplying a second extracted pattern from said input image, said multi-image pattern consisting of multiple second extracted patterns; detecting means for detecting a light from said third display means; and wherein said first, second and third display means are aligned so that said light emitted from said light source passes through said first, second and third display means into said detecting means.

Claim 2

A device for extracting a feature of an input image, said device comprising: a light source for emitting a light; first display means having M by N elements for displaying a first extracted pattern from said input image, where M and N are natural numbers; second display means having approximately M 2 by N 2 elements for displaying a direction based pattern representing, for each of a plurality of particular elements on said first extracted pattern, a plurality of elements positioned in a specified range of direction with regard to the particular element on said first extracted pattern displayed on said first display means; third display means having approximately M 2 by N 2 elements for displaying a multi-image pattern obtained by multiplying a second extracted pattern from said input image, said multi-image pattern consisting of multiple second extracted patterns; detecting means for detecting a light from said third display means; and wherein said first, second and third display means are aligned so that said light emitted from said light source passes through said first, second and third display means into said detecting means.

Claim 6

A device for extracting a feature of an input image, said device comprising: first display means having M by N elements for displaying a first extracted pattern of said input image, whore M and N are natural numbers; second display means having approximately M 2 by N 2 elements for displaying a direction based pattern representing, for each of a plurality of particular elements on said first extracted pattern, a plurality of elements positioned in a specified range of direction with regard to the particular element on said first extracted pattern displayed on said first display means; third display means for displaying a second extracted pattern of said input image; multiply means for multiplying said second extracted pattern so as to form multiplied second extracted patterns totaling approximately M 2 by N 2 elements; overlapping means including a mirror for overlapping said first extracted pattern displayed on said first display means, said direction based pattern displayed on said second display means and said multiplied second extracted patterns formed by said multiply means; detecting means for detecting a light from said overlapping means; first directing means for directing a light to said third display means as a reading light and for directing a light reflected by said third display means to said overlapping means as a writing light through said multiply means and said second display means; and second directing means for directing a light to said first display means as a reading light, for directing a light reflected by said first display means to said overlapping means as a reading light, and for directing a light reflected by said overlapping means to said detecting means.

Claim 7

A device for extracting a feature of an input image, said device comprising: first display means having M by N elements for displaying a first extracted pattern of said input image, whore M and N are natural numbers; second display means having approximately M 2 by N 2 elements for displaying a direction based pattern representing, for each of a plurality of particular elements on said first extracted pattern, a plurality of elements positioned in a specified range of direction with regard to the particular element on said first extracted pattern displayed on said first display means; third display means for displaying a second extracted pattern of said input image; multiply means for multiplying said second extracted pattern so as to form multiplied second extracted patterns totaling approximately M 2 by N 2 elements; overlapping means including a mirror for overlapping said first extracted pattern displayed on said first display means, said direction based pattern displayed on said second display means and said multiplied second extracted patterns formed by said multiply means; detecting means for detecting a light from said overlapping means; first directing means for directing a light to said third display means as a reading light and for directing a light reflected by said third display means to said overlapping means as a writing light through said multiply means and said second display means; and second directing means for directing a light to said first display means as a reading light, for directing a light reflected by said first display means to said overlapping means as a reading light, and for directing a light reflected by said overlapping means to said detecting means.
