Abstract

PROBLEM TO BE SOLVED: To omit a job that is needed for deciding both a turning direction and a turning angle of an image to be processed imaginarily and to set the image in a desired state by a single operation by displaying a command showing the initial state of the image in a symbol mark and turning the image around a prescribed axis by a prescribed angle in response to a selected command. SOLUTION: A command display part displays, on a display device, a command to turn an image to be processed around a prescribed axis by a prescribed angle, and the command shows the initial state of the image in a symbol. In this example, the commands 50, 52 and 54 are shown to turn clockwise the image by 270, 180 and 90 degrees around an axis set vertical to the image along with a command 56 to turn clockwise the image by 180 degrees around an axis set along the image. If an image read out of a scanner is turned sideways, for example, the image is turned by an image turning means in response to a command that is selected from a plurality of displayed commands.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an image processing technique for rotating an image, and more particularly to a technique for reliably and easily specifying a command for rotating an image.

[0002]

2. Description of the Related Art In a conventional image processing apparatus, when an image is rotated, a command designation method for designating a rotation direction and a rotation angle of the image has been adopted. For this reason, in the conventional command designation method, it is necessary to determine the rotation direction and rotation angle of the image while imaging the current and rotated image states in the mind.

However, if the rotation direction and rotation angle of an image are determined in such a manner,
In many cases, an error occurs in the determination of the rotation angle or the like, and the state of the image after the rotation is not as expected. In this case,
It is sufficient to rotate the image again, but there is a disadvantage that extra operations increase.

In view of the above-mentioned conventional problems, the present invention eliminates the need to determine the rotation direction and rotation angle of an image in the head, and makes the image a desired state with a single operation. The aim is to provide a technology that can.

Refers to symbols such as figures and characters. Further, “rotating an image by a predetermined angle around a predetermined axis” means “rotation” if the predetermined axis is set perpendicular to the image, and “reversal” if the predetermined axis is set along the image. Are two types of image processing.

According to this configuration, for example, when the image read from the scanner is facing sideways, the image may be rotated in the normal direction as follows. That is, a command is selected by the command selection means from the commands displayed by the command display means. At this time,
Since the initial state of the image to be processed is displayed as a symbol in the command, it is not necessary to imagine the current and rotated image states in the mind, and it is sufficient to consider only the initial state of the image. Therefore, the designation of the command to rotate the image is intuitively performed, human errors accompanying the determination of the rotation direction and the rotation angle of the image are prevented, and the designation of the command is performed reliably and easily. Thereafter, the image is rotated by the image rotating means based on the selected command.

According to such a configuration, if commands are displayed in a menu format, operational consistency with other applications is ensured, and it is not necessary to learn a new operation procedure for the image processing apparatus. In addition, if the command is displayed in the button mode, the command is specified by one operation while maintaining the operational consistency with other applications, and the operability is improved.

According to a third aspect of the present invention, there is provided a rotation range setting means for setting a rotation range of an image, wherein the image rotation means sets the rotation range when the rotation range is set by the rotation range setting means. It is characterized in that only the image inside is rotated.

According to such a configuration, when it is desired to rotate not a whole image but a part thereof, the rotation range of the image may be set by the rotation range setting means. Thereafter, when a command is selected, only the image within the set rotation range is rotated.

And the image processing method is configured.

According to this configuration, for example, when the image read from the scanner is facing sideways, the image may be rotated in the normal direction as follows. That is, a command is selected from the commands displayed in the command display step in the command selection step. At this time,
Since the initial state of the image to be processed is displayed as a symbol in the command, it is not necessary to imagine the current and rotated image states in the mind, and it is sufficient to consider only the initial state of the image. Therefore, the designation of the command to rotate the image is intuitively performed, human errors accompanying the determination of the rotation direction and the rotation angle of the image are prevented, and the designation of the command is performed reliably and easily. Thereafter, based on the selected command, the image is rotated in the image rotation step.
