2. Description of the Related Art Conventionally, image editing such as changing the size of digital images such as photographs and moving images, transforming them, and adding various effects has been widely and commonly performed using a personal computer or the like. For example, various UIs (user interfaces) are used in image transformation that transforms the shape of an original image. For example, as shown in FIG. The deformation range is specified by enclosing it with the UI of a rectangular frame 81 that is the initial position of the deformation. Thereafter, as shown in FIG. 13B, the rectangular frame 81 is scaled to scale the image 80, and as shown in FIG. 13C, the rectangular frame 81 is rotated to scale the selected image. The tilted image 80 can be expanded or contracted by rotating the image 80 or further expanding or contracting the rectangular frame 81 in the longitudinal direction after the image 80 is rotated as shown in FIG. 13(d).

For example, when deforming a rectangular image into an arbitrary rectangular shape, the presence or absence of perspective can be arbitrarily selected, or when a rectangular image is deformed into an arbitrary deformed image, the perspective can be automatically adjusted. A deformation device has been disclosed (see, for example, Patent Document 1).

Although the image processing apparatus 1 and the operation of the image processing apparatus 1 will be described below assuming one computer, the processing may be distributed among a plurality of computers.

The control unit 10 uses a processor such as a CPU and a memory to control components of the image processing apparatus 1 to realize various functions. In the first embodiment, the control unit 10 executes an image processing program 1P stored in the storage unit 12, for example, to display an image transformation UI and perform image transformation processing. That is, the control unit 10 performs predetermined UI display/transformation processing on input target image data (target data), and performs calculations for the UI display/transformation processing.

The image processing unit 11 uses a processor such as a GPU or a dedicated circuit and a memory, and executes image processing according to control instructions from the control unit 10 . Note that the control unit 10 and the image processing unit 11 are configured as one piece of hardware (SoC: System on a Chip) in which a processor such as a CPU or GPU, a memory, a storage unit 12 and a communication unit 13 are integrated. good too.

The storage unit 12 uses a hard disk or flash memory. The storage unit 12 stores an image processing program 1P, image data 1D to be displayed on the display unit 14, and the like. This image data 1D is, for example, image data obtained from a network via the communication unit 13 or image data read from the reading unit 16. FIG.

The communication unit 13 is a communication module that realizes communication connection to a communication network such as the Internet. For the communication unit 13, for example, a network card, a wireless communication device, or a carrier communication module is used.

The display unit 14 uses a liquid crystal panel, an organic EL (Electro Luminescence) display, or the like.

Prepare. The image processing apparatus 1 generates and displays an image transformation UI for stretching, transforming, moving, and rotating an image such as an oblique image. Upon receiving an instruction from the user, the initial position determination unit 15a determines a rectangular area (rectangular frame) surrounding this image and serving as an initial position for image transformation. The tilt angle designation unit 15b designates the tilt angle of the rectangular area determined by the initial position determination unit 15a in response to an instruction from the user. The UI center position specifying unit 15c specifies the center position of the UI for image transformation in response to an instruction from the user. Although a rectangular area is used as the initial position here, other rectangular areas such as squares or polygonal areas may be used.

The control unit 10 includes a UI generation unit 10a, and the UI generation unit 10a generates an image transformation UI tilted at the tilt angle designated by the tilt angle designation unit 15b. The display unit 14 displays at least a target image and an image transformation UI surrounding this image on the display. The operation unit 15 is used to expand, contract, move, and rotate the target image by expanding/contracting, moving, and rotating the UI for image deformation displayed on the display unit 14 .

A description will be given of a case of stretching and deforming in a maintained state.

In the case of the first example shown in FIG. 2A, first, the user surrounds at least the tilted image S via the initial position determination unit 15a, and stretches and deforms the tilted image S while maintaining the tilt angle. A rectangular area L that is the initial position is specified. For example, when the tilt image S is rectangular, the rectangular area L is a rectangular frame that circumscribes the four corners of the rectangular area. Next, the user designates the tilt angle (about 20 degrees in the example of this figure) via the tilt angle designating section 15b. Here, the angle of inclination is described as the angle when the rectangular area L rotates counterclockwise from the horizontal state.

Then, the UI generation unit 10a that has received the tilt angle instruction from the tilt angle designation unit 15b generates a minimum rectangle that has the tilt angle and surrounds the tilt image S as the image deformation UI (1a), Displayed on the display unit 14 . After that, the user expands or contracts the image deformation UI (1a) via the operation unit 15, so that the inclined image S is expanded or contracted in an upright state. Note that the image deformation that stretches and deforms the tilted image S while maintaining the tilt angle is a so-called general conversion formula such as a conversion formula in which the aspect ratio of the coordinate points forming the tilted image is fixed, or a conversion formula for the coordinate points in the projective transformation. It is possible to apply the technique of expanding and contracting from the original square to another square, which is used in . An upright image generally refers to an image that is displayed in the correct vertical direction (the direction in which characters and images are not reversed), that is, an image that is not reversed vertically (horizontally). In the description of the first embodiment, it is assumed that stretchable images that are not upside down and that have the same tilt angle are included.

In the case of the second example shown in FIG. 2B, first, the user encloses at least the tilted image S via the initial position determination unit 15a, and stretches and deforms the tilted image S while maintaining the tilt angle. Specifies a rectangular area L indicating the initial position for Next, the user designates the tilt angle (about 20 degrees in the example of this figure) via the tilt angle designating section 15b. Then, the UI generation unit 10a, which has received the tilt angle instruction from the tilt angle specifying unit 15b, satisfies the condition that the center position C1 of the rectangular area is the center, and the minimum distance surrounding the tilt image S has the tilt angle. A rectangle is generated as an image transformation UI (1b) and displayed on the display unit 14. FIG. In this second example, when the user designates only the tilt angle, the minimum rectangle that satisfies the conditions centered on the designated tilt angle and the center C1 is selected for image transformation while the center of the rectangular area L is fixed. Generated and displayed as UI (1b). After that, the user expands and contracts the image deformation UI (1b) via the operation unit 15, thereby expanding and contracting the tilt image S in an upright state.

In the case of the third example shown in FIG. 3A, first, the user encloses at least the tilted image S via the initial position determination unit 15a, and stretches and deforms the tilted image S while maintaining the tilt angle. Specifies a rectangular area L indicating the initial position for Next, the user designates the tilt angle (approximately 20 degrees in the example of this drawing) via the tilt angle designating section 15b, and designates the center position C2 of the UI for image transformation via the UI center position designating section 15c. . Then, the UI generation unit 10a receives the command of the tilt angle from the tilt angle designation unit 15b and the designation of the center position C2 of the UI for image transformation from the UI center position designation unit 15c. A minimum rectangle that satisfies the condition that the central position C2 specified by the specifying unit 15c is the center and surrounds the tilted image S is generated as an image transformation UI (1c) and displayed on the display unit 14. FIG. After that, the user expands and contracts the image deformation UI (1c) via the operation unit 15, thereby expanding and contracting the tilt image S in an upright state.

In the case of the fourth example shown in FIG. 3B, first, the user encloses at least the tilted image S via the initial position determination unit 15a, and stretches and deforms the tilted image S while maintaining the tilt angle. Specifies a rectangular area L indicating the initial position for Next, the user designates the tilt angle (about 20 degrees in the example of this figure) via the tilt angle designating section 15b. Upon receiving the tilt angle instruction from the tilt angle designation unit 15b, the UI generation unit 10a generates an image of a minimum rectangle having the tilt angle designated by the tilt angle designation unit 15b and circumscribing the four corners of the rectangular region L. A UI for transformation (1d) is generated and displayed on the display unit 14. FIG. After that, the user expands and contracts the image deformation UI (1d) via the operation unit 15, so that the tilt image S is expanded and contracted in an upright state. FIG. 4(a) shows a state in which the UI for image transformation (1d) is generated and displayed in the fourth example, and the UI for image transformation (1d) is stretched so as to be tilted as shown in FIG. 4(b). The image S can be stretched upright.

Next, the operation procedure of the image processing apparatus 1 according to the first embodiment will be described with reference to the flowchart shown in FIG. Here, the operation procedure in the case of the third example described above will be described.

First, the user designates a rectangular area (rectangular frame) that surrounds at least the tilted image and indicates the initial position for stretching, moving, and rotating the tilted image via the initial position determination unit 15a (S51). Next, the user designates the tilt angle of the image transformation UI generated by designating the tilt angle of the rectangular area via the tilt angle designating section 15b (S52). Then, it is determined whether or not to specify the center position of the UI for image transformation (S53). Here, if the center position of the UI for image transformation is designated (Yes in S53), the UI generation unit 10a has the designated tilt angle and the center position designated by the UI center position designation unit 15c. A minimum rectangle that satisfies the condition centered on and surrounds the tilted image is generated as an image transformation UI and displayed on the display unit 14 (S54). On the other hand, if the center position of the UI for image transformation is not required (No in S53), the UI generation unit 10a creates a minimum rectangle that has the specified tilt angle and surrounds the tilted image for image transformation. The UI is generated and displayed on the display unit 14 (S55).

Next, a specific example of a method of designating the tilt angle via the tilt angle designating section 15b will be described with reference to FIG. The tilt angle designation unit 15 b may designate the tilt angle by dragging any of the four corners of the rectangular area L displayed on the display unit 14 . Alternatively, as shown in FIG. 6A, for example, the angle of inclination may be specified using a rotation handle 61 integral with or separate from the rectangular area L displayed on the display unit 14.

Furthermore, as shown in FIG. 6(b), a slider 62 for designating the rotation angle may be displayed on the display unit 14, and a control window 63 as shown in FIG. Alternatively, the tilt angle may be entered in the angle numerical value input box 63a and determined using the determination button 63b. In other words, the tilt angle designating section 15b may be of any form as long as it can designate the tilt angle to be applied to the rectangular area. Similarly, the UI center position specifying unit 15c may specify the center position of the UI for image transformation by dragging a movable cross pointer.
