Abstract
A printer includes a control unit and a printing unit. The control unit determines whether a portion of the print image referred to as a target region is blank. The printing unit cancels printing of the print image when the control unit determines that the target region is blank.
Claims20
A printer, comprising:
- a control unit that determines whether a target region of a print image is blank, the target region being a portion of the print image;
- and
- a printing unit that cancels printing of the print image when the control unit determines that the target region is blank.
A printing method, comprising:
- determining whether a target region of a print image is blank, the target region being a portion of the print image;
- and
- canceling printing of the print image when the target region is determined to be blank.
An image processing device, comprising:
- an identifying unit that identifies a blank region in each pixel line included in an image based on a density level of each pixel included in the pixel line;
- a coupling unit that couples adjacent blank regions among the blank regions identified in the pixel lines;
- and
- an output unit that outputs information on a blank region in the image based on a coupling result by the coupling unit,
- wherein the pixel lines include a first pixel line including, in the listed order, a first pixel, a second pixel, and a third pixel adjacent to the second pixel, and
- the identifying unit:
- identifies a position of the first pixel as a start position of the blank region in the first pixel line when the density level of the first pixel is less than a threshold level;
- and
- identifies a position of the second pixel as an end position of the blank region in the first pixel line when the density level of the second pixel is within a first predetermined range and the density level of the third pixel is outside a second predetermined range.
