US 7,925,115 B2 · Image processing device capable of detecting and correcting inclination of image

Abstract

An image process capable of rapidly detecting and correcting the inclination of a document image is executed as follows. Dots are put on a document image at even intervals and the document image is printed to provide a printed object. The printed object is read with a scanner to provide image data. Processes are performed on the image data with a plurality of filters for detecting dots corresponding to a plurality of inclinations to calculate the degrees of agreement between the data and the filters. The inclination angle of a filter exhibiting a highest degree of agreement is set to the inclination angle.

Dependent claims

An image processing device comprising:

an inputting portion which inputs image data obtained by reading a printed object having dots put thereon at a predetermined interval;
a first processor which processes said input image data with a first filter for detecting inclination agreement between said dots on the printed object and dots which are included in the first filter and arranged at a first inclination angle and at the predetermined interval;
a second processor which processes said input image data with a second filter for detecting inclination agreement between said dots on the printed object and dots which are included in the second filter and arranged at a second inclination angle being different from the first inclination angle and at the predetermined interval;
and
a detector which detects an inclination angle of said image data, on the basis of an output from the processes performed by said first and second processors.

An image processing method performed in an electronic image processing apparatus of the type including an interface for receiving image data, a processor, and a storage device, said method comprising:

an inputting step of inputting, into said electronic image processing apparatus via said interface, image data obtained by reading a printed object having dots put thereon at least in a single direction at a predetermined interval;
a first processing step of processing, with said processor of said electronic image processing apparatus, said image data with a first filter for detecting inclination agreement between dots included in the first filter and the dots on the printed object, said dots included in the first filter being arranged at a first inclination angle and at the predetermined interval;
a second processing step of processing, with said processor of said electronic image processing apparatus, said image data with a second filter for detecting inclination agreement between dots included in the second filter and the dots on the printed object, said dots included in the second filter being arranged at a second inclination angle and at the predetermined interval;
and
a detecting step of detecting, with said processor of said electronic image processing apparatus, an inclination angle of said image data, on the basis of an output obtained by said first and second processing steps.
