Abstract
A method of controlling an image processing apparatus makes it possible to suppress, in an auto color selection function, color determination resulting from a minute color element of a document without troubling a user.
Claims8
An image processing apparatus, comprising:
- a reading unit configured to read a document and generate image data;
- a determination unit configured to determine whether the document is a color document or a monochrome document based on the image data and a reference value of a number of color pixels;
- a processing unit configured to process the image data based on a result of the color determination;
- a displaying unit configured to display a screen including a first object for setting a first reference value as the reference value and a second object for setting a second reference as the reference value;
- and
- a user interface, wherein
- the determination unit determines that the document is the color document at least based on the number of color pixels included in the image data exceeding the first reference value in a case where the first object is selected by the user interface,
- the determination determines that the document is the monochrome document at least based on the number of color pixels included in the image not exceeding the first reference value in a case where the first object is selected by the user interface,
- the determination unit determines that the document is the color document at least based on the number of color pixels included in the image data exceeding the second reference value in a case where the second object is selected by the user interface,
- the determination determines that the document is the monochrome document at least based on the number of color pixels included in the image data not exceeding the second reference value in a case where the second object is selected by the user interface, and
- wherein the second value is greater than the first reference value.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute a method of controlling an image processing apparatus, the method comprising:
- reading a document and generating image data,
- determining whether the document is a color document or a monochrome document based on the image data and a reference value of a number of color pixels;
- processing the image data based on a result of the color determination;
- and
- displaying a screen including a first object for setting a first reference value as the reference value and a second object for setting a second reference value as the reference value,
- wherein
- it is determined that the document is the color document at least based on the number of color pixels included in the image data exceeding a first reference value in a case where the first object is selected by a user,
- it is determined that the document is the monochrome document at least based on the number of color pixels included in the image data not exceeding the first reference value in a case where the first object is selected by the user,
- it is determined that the document is the color document at least based on the number of color pixels included in the image data exceeding a second reference value in a case where the second object is selected by the user,
- it is determined that the document is the monochrome document at least based on the number of color pixels included in the image data not exceeding the second reference value in a case where the second object is selected by the user, and
- the second reference value is greater than the first reference value.
