Image processing apparatus, control method, and storage medium capable of suppressing image degradation

A non-transitory computer readable storage medium storing one or more computer-executable programs configured to be executed by one or more processors, the one or more computer-executable programs including instructions for:

• acquiring transmission information indicating a transparent state of each pixel of an image to be subjected to image processing and color information of each pixel of the image;
• acquiring a ratio of a completely transparent region to an entire region of the image based on the acquired transmission information;
• performing control so as to execute a first image processing based on color information of a first number of pixels in the image in a case that the acquired ratio is less than a first threshold value;
• and
• performing control so as to execute a second image processing based on color information of a second number of pixels, the second number being obtained by deleting at least a portion of the completely transparent region in the image and less than the first number, in a case that the acquired ratio is greater than or equal to the first threshold value and is less than a second threshold value greater than the first threshold value.

An image processing apparatus comprising:

• at least one memory and at least one processor and/or at least one circuit that function as:
• a first acquisition unit that acquires transmission information indicating a transparent state of each pixel of an image to be subjected to image processing and color information of each pixel of the image;
• a second acquisition unit that acquires a ratio of a region of a specific color to an entire region of the image by referring to the acquired color information in a case that the transmission information has been acquired from the image;
• and
• a control unit that performs control so as to execute a first image processing based on color information of a first number of pixels in the image in a case that the acquired ratio is less than a first threshold value, and performs control so as to execute a second image processing based on color information of a second number of pixels, the second number being obtained by deleting at least a portion of the region of the specific color in the image and less than the first number, in a case that the acquired ratio is greater than or equal to the first threshold value and is less than a second threshold value greater than the first threshold value.
