Abstract: An upper surface of a substrate is supplied with a pre-drying processing liquid which is a solution of a sublimable substance and a solvent. Thereafter, the solvent is evaporated from the pre-drying processing liquid on the substrate and a solid of the sublimable substance is precipitated in the pre-drying processing liquid on the substrate. Thereafter, at least a portion of the solid of the sublimable substance is dissolved in the pre-drying processing liquid on the substrate. Thereafter, the solvent is evaporated from the pre-drying processing liquid in which the solid of the sublimable substance has been dissolved and the solid of the sublimable substance is precipitated onto the substrate. Thereafter, the solid of the sublimable substance is sublimated and removed from the upper surface of the substrate.

Abstract: An image recording apparatus includes a roller pair for transporting a sheet, a recording head, and a controller. The controller determines a linefeed amount by which the sheet is transported by the roller pair between corresponding two adjacent passes of the recording head. The controller executes image recording on the sheet by alternately repeating a linefeed operation for rotating the roller pair by the determined linefeed amount to transport the sheet in a transport direction, and a pass recording operation in which the controller causes the roller pair to stop and the recording head to perform a pass and to record part of an image on the sheet. Upon determining that a linefeed operation would cause the sheet to travel past the roller pair while the roller pair is decelerating, replace for the linefeed operation a determined linefeed amount by an adjusted linefeed amount.

Abstract: Posture information corresponding to a line of an input image is calculated. Then, a first virtual line, which is a line in a line direction of the input image for which the posture information calculated is common, is rotated according to the posture information to obtain a second virtual line on the output image. For each pixel of the output image, a corresponding second virtual line is calculated, and posture information is obtained on the basis of the corresponding second virtual line. Then, for coordinates of each pixel of the output image, the reference coordinates on the input image corresponding to the pixel coordinates is calculated using the associated posture information. By cutting out the output image from the input image on the basis of the reference pixel, highly accurate distortion correction can be realized even in a case where the camera posture differs depending on the line.
