Abstract: After a difference image between original image and calibration image is generated, a candidate image of an edge region is generated. Thereafter, an edge image is generated based on the original image, the calibration image, and the candidate image. At that time, the processing target pixel (pixel constituting the candidate image) is determined to be a pixel constituting the edge region when a difference between a pixel value of at least one of nine comparison target pixels in the original image and a pixel value of the processing target pixel in the calibration image is less than or equal to a first threshold value, and when a difference between a pixel value of at least one of nine comparison target pixels in the calibration image and a pixel value of the processing target pixel in the original image is less than or equal to the first threshold value.

Abstract: A printing apparatus includes a transport unit that intermittently transports a medium, a support portion that supports the medium, a head that performs printing by discharging a liquid onto the medium supported by the support portion during a period in which the transport of the medium by the transport unit is stopped, a carriage at which the head is mounted and that moves relative to the medium, and a control unit. The control unit causes the head to discharge the liquid onto a printing region while moving the carriage, the printing region being a region, of the medium, supported by the support portion, and starts the transport of the medium by the transport unit after the discharge of the liquid by the head is completed and before the carriage stops.
