Abstract
An image processing apparatus includes: a designating unit configured to designate a color; a reading unit configured to read a document to generate a document image; a conversion unit configured to convert a color of a pixel in the document image to a specific color based on a designated color designated by the designating unit; and a specification unit configured to specify a graphic region in the document image. The conversion unit is configured not to convert a color of a pixel in the graphic region specified by the specification unit to the specific color.
Claims12
An image processing apparatus comprising:
- a reader configured to read a document to generate a document image;
- and
- processing circuitry configured to:
- receive an input to designate a color;
- specify a graphic region in the document image and a removal region in the document image, the removal region being a region other than the specified graphic region;
- and
- convert a color of a pixel of interest in the removal region whose color corresponds to the designated color to a specific color,
- wherein the processing circuitry is configured not to convert a color of a pixel in the specified graphic region of the document image to the specific color.
An image processing method performed by processing circuitry of an image processing apparatus that includes a reader, the method comprising:
- causing the reader to read a document to generate a document image;
- receiving an input to designate a color;
- specifying a graphic region in the document image and a removal region in the document image, the removal region being a region other than the specified graphic region;
- converting a color of a pixel of interest in the removal region whose color corresponds to the designated color to a specific color;
- and
- skipping conversion of a color of a pixel in the specified graphic region of the document image to the specific color.
A non-transitory computer-readable storage medium having stored therein a computer program which, when executed by a processor of an image processing apparatus, causes the image processing apparatus to perform operations comprising:
- causing a reader of the image processing apparatus to read a document to generate a document image;
- receiving an input to designate a color;
- specifying a graphic region in the document image and a removal region in the document image, the removal region being a region other than the specified graphic region;
- converting a color of a pixel of interest in the removal region whose color corresponds to the designated color to a specific color;
- and
- skipping conversion of a color of a pixel in the specified graphic region of the document image to the specific color.
