Abstract
A recording control device that controls a recording device that discharges a dot to perform recording includes an edge detection unit configured to detect an edge of an image represented by image data, and a recording control unit configured to generate dot data specifying the dot based on the image data and to cause the recording device to perform recording based on the dot data. The recording control unit causes an internal region, located on an inner side of an edge region including the edge of the image, to be recorded using a dot having a smaller size than that of a dot used for recording of the edge region, or to be dot-off.
Claims9
A recording control device that controls a recording device that discharges a dot to perform recording, the recording control device comprising:
- a processor configured to detect an edge of an image represented by image data,
- the processor being further configured to generate dot data of the image that specifies dot size of each pixel of the image based on the image data and to cause the recording device to perform recording of the image based on the dot data of the image, wherein
- while generating the dot data of the image, the processor is configured to
- compare, for each pixel of an internal region of the image, dot size of a pixel of the internal region with dot size of at least part of pixels of an edge region of the image, and
- replace the dot size of the pixel of the internal region based on the comparison result such that the pixel of the internal region is recorded using a dot having a smaller size than that of a dot used for recording the at least part of the pixels of the edge region, or is dot-off, the internal region being located on an inner side of the edge region, the edge region including the edge of the image, and
- the processor is configured to change the edge region and the internal region in accordance with a type of a recording medium on which recording is performed by the recording device.
A recording device that discharges a dot to perform recording, the recording device comprising:
- a processor configured to detect an edge of an image represented by image data,
- the processor being further configured to generate dot data of the image that specifies dot size of each pixel of the image based on the image data and to perform recording of the image based on the dot data of the image, wherein
- while generating the dot data of the image, the processor is configured to
- compare, for each pixel of an internal region of the image, dot size of a pixel of the internal region with size data of at least part of pixels of an edge region of the image, and
- replace the dot size of the pixel of the internal region based on the comparison result such that the pixel of the internal region is recorded using a dot having a smaller size than that of a dot used for recording the at least part of the pixels of the edge region, or is dot-off, the internal region being located on an inner side of the edge region, the edge region including the edge of the image, and
- the processor is configured to change the edge region and the internal region in accordance with a type of a recording medium on which recording is performed by the recording device.
A recording control method for controlling a recording device that discharges a dot to perform recording, the recording control method comprising:
- detecting an edge of an image represented by image data;
- and
- generating dot data of the image that specifies dot size of each pixel of the image based on the image data and causing the recording device to perform recording of the image based on the dot data of the image, wherein
- while generating the dot data of the image, for each pixel of an internal region of the image, dot size of a pixel of the internal region is compared with dot size of at least part of pixels of an edge region of the image, and the dot size of the pixel of the internal region is replaced based on the comparison result such that the pixel of the internal region is recorded using a dot having a smaller size than that of a dot used for recording the at least part of the pixels of the edge region, or is dot-off, the internal region being located on an inner side of the edge region, the edge region including the edge of the image, and
- the edge region and the internal region are changed in accordance with a type of a recording medium on which recording is performed by the recording device.
