Abstract
An image processing apparatus is provided. The apparatus detects an edge in an N-arized image (N is a natural number not less than 2) representing a result of threshold-based processing for a grayscale image obtained from an input image. The apparatus generates the print data based on the input image and a detection result of the edge.
Claims26
An image processing apparatus for generating print data of at least one color, which is used by a printing apparatus for printing an image on a print medium by adhering a recording material of at least one color to the print medium in accordance with the print data, the image processing apparatus comprising one or more memories storing instructions and one or more processors that execute the instructions to:
- detect an edge in an N-arized image (N is a natural number not less than 2) representing a result of threshold-based processing for a grayscale image obtained from an input image;
- and
- generate the print data based on the input image and a detection result of the edge.
An image processing apparatus for generating print data corresponding to each color, which is used by a printing apparatus for printing an image on a print medium by adhering a recording material of at least one color to the print medium in accordance with the print data, the image processing apparatus comprising one or more memories storing instructions and one or more processors that execute the instructions to:
- detect an edge in a grayscale image corresponding to an input image;
- and
- generate the print data based on the input image, a detection result of the edge, and a pixel value at the edge of the grayscale image.
An image processing apparatus comprising one or more memories storing instructions and one or more processors that execute the instructions to:
- detect an edge in an N-arized image (N is a natural number not less than 2) representing a result of threshold-based processing for a grayscale image obtained from an input image;
- and
- generate, based on the input image and a detection result of the edge, color separation data indicating a recording amount for each pixel and a detection result of the edge for each pixel and corresponding to a recording material used by a printing apparatus for printing.
The image processing method of generating print data of at least one color, which is used by a printing apparatus for printing an image on a print medium by adhering a recording material of at least one color to the print medium in accordance with the print data, comprising:
- detecting an edge in an N-arized image (N is a natural number not less than 2) representing a result of threshold-based processing for a grayscale image obtained from an input image;
- and
- generating the print data based on the input image and a detection result of the edge.
A non-transitory computer-readable medium storing a program executable by a computer to perform a method of generating print data of at least one color, which is used by a printing apparatus for printing an image on a print medium by adhering a recording material of at least one color to the print medium in accordance with the print data, comprising:
- detecting an edge in an N-arized image (N is a natural number not less than 2) representing a result of threshold-based processing for a grayscale image obtained from an input image;
- and
- generating the print data based on the input image and a detection result of the edge.
