Abstract
An image processing apparatus for detecting the inclination of an object is provided. This image processing apparatus has a read means which reads the object and outputs image data, an amount of change calculation means which calculates the sum of the amounts of change of the image data of the object in at least one direction, and an inclination calculation means which calculates the inclination of the object based on the sum calculated by the amount of change calculation means.
Claims42
An image processing apparatus for detecting an inclination of an object, comprising:
- a read means which reads said object and outputs image data;
- an amount of change calculation means which calculates a sum of amounts of change of said image data in said object in at least one direction, wherein said amount of change calculation means has a means which calculates said sum calculated in a first direction in said object and said sum calculated in a second direction that is perpendicular to said first direction, and wherein said inclination calculation means has a means which calculates said inclination of said object using a ratio between said sum calculated in said first direction and said sum calculated in said direction;
- and
- an inclination calculation means which calculates an inclination of said object based on said sum calculated by said amount of change calculation means.
An image processing apparatus for detecting an inclination of an object, comprising:
- a read means which reads said object and outputs image data;
- an amount of change calculation means which calculates a sum of amounts of change of said image data in said object in at least one direction;
- and
- an inclination calculation means which calculates an inclination of said object based on said sum calculated by said amount of change calculation means;
- wherein said inclination calculation means has a modification means which modifies said image data to create a modified image that corresponds to said image data when said object is rotated;
- and a repetition means which repeats having said amount of change calculation means calculate said sum, while having said modification means modify said image;
- and
- said inclination calculation means calculates said inclination of said object based on an amount of modification of said image data modified by said modification means when said sum satisfies a prescribed condition.
An image processing method for detecting an inclination of an object, comprising:
- reading said object for outputting image data;
- calculating a sum of change amounts in said image data in one direction;
- and
- calculating an inclination of said object based on said sum,
- wherein calculating said sum calculates said sums in a first direction of said object and in a second direction that is perpendicular to said first direction;
- and
- said calculating said inclination calculates said inclination using a ratio between said sums calculated in said first and second directions.
