Image processing apparatus, method of controlling the same, and storage medium

An image processing apparatus that generates monochromatic image data on the basis of print data including a command to draw a chromatic colored object, the apparatus comprising:

• a memory device that stores a set of instructions;
• and
• at least one processor that executes instructions stored in the memory device to function as:
• a receiving unit that receives print data including at least a first drawing command for drawing a first chromatic colored object and a second drawing command for drawing a second chromatic colored object;
• a determining unit that determines whether or not a size of the first chromatic colored object and a size of the second chromatic colored object are greater than a predetermined size;
• a converting unit that converts the first drawing command into a third drawing command for drawing a monochromatic image of a first chromatic colored object determined to have a size less than or equal to the predetermined size so that the first chromatic colored object has a higher density, after being converted into a monochromatic image, than a first chromatic colored object determined to have a size greater than the predetermined size, and converts the second drawing command into a fourth drawing command for drawing a monochromatic image of a second chromatic colored object determined to have a size less than or equal to the predetermined size so that the second chromatic colored object has the same density, after being converted into a monochromatic image, as a second chromatic colored object determined to have a size greater than the predetermined size;
• and
• a generating unit that generates monochromatic image data by executing the third drawing command and the fourth drawing command obtained from the conversion by the converting unit.

A method for controlling an image processing apparatus, the method comprising:

• extracting, from color image data, an object having a first density and an object having a second density that is higher than the first density;
• determining whether or not a size of the object having the first density and a size of the object having the second density, extracted in the step of extracting, are greater than a predetermined size;
• and
• converting the color image data into monochromatic image data,
• wherein the converting carries out conversion so that an object having the first density and a size less than or equal to the predetermined size has a higher density than an object having the first density and a size greater than the predetermined size, and carries out conversion so that an object having the second density and a size less than or equal to the predetermined size has the same density as an object having the second density and a size greater than the predetermined size.

A non-transitory computer-readable storage medium storing a program for causing a processor to execute a method for controlling an image processing apparatus, the method comprising:

• extracting, from color image data, an object having a first density and an object having a second density that is higher than the first density;
• determining whether or not a size of the object having the first density and a size of the object having the second density, extracted in the step of extracting, are greater than a predetermined size;
• and
• converting the color image data into monochromatic image data,
• wherein the converting carries out conversion so that an object having the first density and a size less than or equal to the predetermined size has a higher density than an object having the first density and a size greater than the predetermined size, and carries out conversion so that an object having the second density and a size less than or equal to the predetermined size has the same density as an object having the second density and a size greater than the predetermined size.
