Abstract

Abstract An image processor having a circuit for holding data on features of registered specific images, a circuit for determining the degree of similarity between features of an input image and the held features of each of the specific images, and a circuit for updating the held content of the holding circuit from the outside through a line. The image processor also has a judgment circuit for determining the degree of similarity between an input image and each of the specific images according to tint distributions of these images, and a circuit for registering data on the tint distribution of each specific image.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 113 words
An image processing method for forming, in a memory, a judgment standard to be used for judging whether an input object is a specific object, said method comprising the steps of: inputting color image data corresponding to a color image with input means; extracting color component data corresponding to the specific object from a selected part of the input color image data among the color image data; and forming a color distribution of the specific object in a selected part of the memory as the judgment standard, based on the extracted component data, wherein the selected part of the input color image data is included in a two-dimensional area on said color image.
Claim 2
Dependent Claim 113 words
An image processing method for forming, in a memory, a judgment standard to be used for judging whether an input object is a specific object, said method comprising the steps of: inputting color image data corresponding to a color image with input means; extracting color component data corresponding to the specific object from a selected part of the input color image data among the color image data; and forming a color distribution of the specific object in a selected part of the memory as the judgment standard, based on the extracted component data, wherein the selected part of the input color image data is included in a two-dimensional area on said color image.
Claim 3
Dependent Claim 24 words
A method according to claim 1, further comprising the step of storing a plurality of color distributions corresponding to a plurality of specific objects.
Claim 4
Dependent Claim 24 words
A method according to claim 1, wherein the input means is an image reading means for scanning an original and generating color image data.
Claim 5
Dependent Claim 25 words
A method according to claim 1, further comprising the step of storing the color image data input by the input means, into a frame memory.
Claim 6
Dependent Claim 18 words
A method according to claim 1, wherein the color component data is expressed by red, green and blue.
Claim 7
Dependent Claim 23 words
A method according to claim 1, further comprising the step of confirming the color distribution of the specific objected formed in the memory.
Claim 8
Dependent Claim 114 words
An image processing apparatus for forming, in a memory, a judgment standard to be used for judging whether an input object is a specific object, said apparatus comprising; input means for inputting color image data corresponding to a color image; means for extracting color component data corresponding to the specific object from a selected part of the input color image data among the color image data; and means for forming a color distribution of the specific object in a selected part of the memory as the judgment standard, based on the extracted component data, wherein, the selected part of the input color image data is included in a two-dimensional area on said color image.
Claim 9
Dependent Claim 114 words
An image processing apparatus for forming, in a memory, a judgment standard to be used for judging whether an input object is a specific object, said apparatus comprising; input means for inputting color image data corresponding to a color image; means for extracting color component data corresponding to the specific object from a selected part of the input color image data among the color image data; and means for forming a color distribution of the specific object in a selected part of the memory as the judgment standard, based on the extracted component data, wherein, the selected part of the input color image data is included in a two-dimensional area on said color image.
Claim 10
Dependent Claim 22 words
An apparatus according to claim 7, wherein the memory stores a plurality of color distributions corresponding to a plurality of specific objects.
Claim 11
Dependent Claim 24 words
An apparatus according to claim 7, wherein said input means is an image reading means for scanning an original and generating color image data.
Claim 12
Dependent Claim 24 words
An apparatus according to claim 7, wherein the memory comprises a frame memory for storing the color image data input by said input means.
Claim 13
Dependent Claim 18 words
An apparatus according to claim 7, wherein the color component data is expressed by red, green and blue.
Claim 14
Dependent Claim 21 words
An apparatus according to claim 7, further comprising means for confirming the color distribution of the specific object formed in memory.
