<One Embodiment>
<Modification>
It should be noted that the embodiments and the like described below are preferable specific examples, and various technically preferable limitations are given, but in the following description, unless there is a statement that the limitation is explicitly made, It is not limited to the embodiment.

<One Embodiment>
1. Configuration of Display Control Device FIG. 1 shows a main configuration example of a display control device 10 in this embodiment. The display control device 10 can be applied to, for example, a personal computer, a notebook personal computer, a portable tablet computer, an imaging device such as a digital camera, a portable music player, and a mobile phone. The configuration example illustrated in FIG. 1 is a main configuration example of the display control device 10, and it is needless to say that various configurations may be added depending on the device to which the display control device is applied.

  The display control apparatus 10 includes a CPU (Central Processing Unit) 1 that controls the entire apparatus. A ROM (Read Only Memory) 2, a RAM (Random Access Memory) 3, a digital signal processing unit 4, and a touch panel 5 are connected to the CPU 1. The CPU 1 is an example of a display control unit and a processing unit, and controls each unit of the display control device 10 by executing a program recorded in the ROM 2, for example. The RAM 3 is used as a work memory when the CPU 1 executes a program, for example.

  The digital signal processing unit 4 executes various signal processing in accordance with control by the CPU 1. Hereinafter, an example of processing executed by the digital signal processing unit 4 will be described. For example, the digital signal processing unit 4 reads image data recorded in the recording device 6 and performs a process of decompressing the read image data. Predetermined signal processing is performed on the decompressed image data, and the image data is converted into an analog signal. The image data converted into the analog signal is supplied to the liquid crystal panel 7, and an image corresponding to the image data is displayed on the liquid crystal panel 7.

  The digital signal processing unit 4 performs processing for deleting predetermined image data recorded in the recording device 6. Further, the digital signal processing unit 4 reduces the image displayed on the liquid crystal panel 7 under the control of the CPU 1. The image data of the image displayed on the liquid crystal panel 7 is subjected to reduction processing by the digital signal processing unit 4, and the image data subjected to the reduction processing is supplied to the liquid crystal panel 7. Then, a reduced image is displayed on the liquid crystal panel 7. In addition to this, the digital signal processing unit 4 performs a process of displaying the original image data instead of the reduced image.

  The recording device 6 is a recording medium that can be attached to and detached from the display control apparatus 10, and is, for example, a USB (Universal Serial Bus) memory. The recording device 6 may be a hard disk or the like built in the display control device 10 instead of a detachable recording medium. Image data is recorded in the recording device 6 as an example of content.

  An image corresponding to the image data is displayed on the liquid crystal panel 7. The liquid crystal panel 7 displays not only images but also information corresponding to application functions of the display control device 10 such as a menu screen and information for assisting operations. The liquid crystal panel 7 may be a panel made of organic EL (Electro Luminescence).

  The liquid crystal panel 7 is configured as a touch panel, and the liquid crystal panel 7 and the touch panel 5 are physically integrated. In this embodiment, the touch panel system is a capacitive system, but various systems such as a resistive film system, an optical system, and an ultrasonic system may be adopted.

  The touch panel 5, which is an example of a position input unit, includes a circuit corresponding to the type of each touch panel, and detects the position of an operation performed on the liquid crystal panel 7. For example, when a position instruction operation in which the user touches the liquid crystal panel 7 is performed, the touch panel 5 detects position coordinates on the liquid crystal panel 7 on which the position instruction operation has been performed.

  The touch panel 5 can be input with a coordinate position by a position instruction operation close to the liquid crystal panel 7. For example, by incorporating a sensor for detecting a minute capacitance in the touch panel 5, it is possible to detect a position indicating operation performed several centimeters away from the liquid crystal panel 7. A position indicating operation close to the liquid crystal panel 7 may be detected using a pyroelectric element that detects a slight infrared ray emitted from a human body.

  The following effects can be obtained by enabling the position indicating operation close to the liquid crystal panel 7. That is, since the liquid crystal panel 7 is not touched directly, the operation can be easily performed without causing friction between the liquid crystal panel 7 and the finger. In addition, effects such as a reduction in finger tension during operation and an operation while confirming an image displayed on the liquid crystal panel 7 can be obtained.

  The position coordinates detected on the touch panel 5 are converted into digital signals, and the digital signals are supplied to the CPU 1. The CPU 1 performs a process according to a signal indicating the position coordinates supplied from the touch panel 5. The above is the main configuration of the display control apparatus 10 in this embodiment.

2. Display Image Example Next, an image displayed on the liquid crystal panel 7 will be described. FIG. 2 shows an example of an image Im1 displayed on the liquid crystal panel 7 in this embodiment. The image Im1 is, for example, substantially rectangular and has a vertical length of H. Image data corresponding to the image Im1 is recorded in the recording device 6.

  In this embodiment, an operation using two fingers is performed on the image Im1 displayed on the liquid crystal panel 7. FIG. 3 schematically shows a finger used for an operation in this embodiment. The length from the tip of the finger to the belly of the finger is x. Although only one finger is shown in FIG. 3, when two or more fingers are used for the operation, any one finger may be used. For example, when an operation is performed using the thumb and index finger, the length from the toe of the thumb to the belly of the finger is x.

3. Outline of Processing Next, an outline of the processing in this embodiment will be described with reference to FIGS. 4A to 4E. As shown in FIG. 4A, an image Im1 is displayed on the liquid crystal panel 7.

  Next, the user performs a position indicating operation for specifying the positions of two positions of the image Im1. For example, a position indicating operation is performed in which two points on the diagonal line connecting the lower left corner and the upper right corner toward the drawing of the image Im1 are substantially simultaneously indicated by using the thumb F1 and the index finger F2. The two positions differ depending on the size of the image Im1, for example, near the lower left corner and near the upper right corner of the image Im1. Then, an operation of pinching the image Im1 is performed by bringing the thumb F1 and the index finger F2 close to each other along the diagonal line.

  Following the movement of bringing the thumb F1 and the index finger F2 closer to each other, the image Im1 is reduced as shown in FIG. 4B. Then, a reduced image Im2 obtained by reducing the image Im1 is displayed on the liquid crystal panel 7. The reduced image Im2 is displayed in the vicinity of the position where the thumb F1 and the index finger F2 are pinched. In addition, a trash can icon Tr is displayed in a region without an image that is generated when the image Im1 is reduced to the reduced image Im2. This trash can icon Tr is an example of display information indicating an operation on the reduced image Im2.

  As shown in FIGS. 4B and 4C, an operation of moving the thumb F1 and the index finger F2 is performed while maintaining a state where the reduced image Im2 is pinched. Following the operation of moving the thumb F1 and the index finger F2, the display position of the reduced image Im2 changes. When the reduced image Im2 is moved to a position where the distance between the reduced image Im2 and the trash can icon Tr becomes a predetermined value or less, the trash can lid of the trash can icon Tr is opened. When the position of the thumb F1 or the index finger F2 cannot be detected on the touch panel 5, the reduced image Im2 and the trash can icon Tr are erased from the liquid crystal panel 7 as shown in FIG. 4D. At this time, the digital signal processing unit 4 deletes the image data of the image Im1 corresponding to the reduced image Im2 under the control of the CPU1.

  When the reduced image Im2 and the trash can icon Tr are erased from the liquid crystal panel 7, an image Im3 that is the next browsing object is displayed on the liquid crystal panel 7, as shown in FIG. 4E. The image data deletion process can be performed on the image Im3 by the same operation as the operation on the image Im1.

4). Details of Processing Next, details of processing in this embodiment will be described with reference to a flowchart shown in FIG. The process shown in FIG. 5 is executed under the control of the CPU 1. In step S1, the image Im1 is displayed on the liquid crystal panel 7. Then, the process proceeds to step S2.

  In step S2, the value of x described with reference to FIG. 3 is detected. In this embodiment, the value of x is, for example, the length from the tip of the thumb F1 to the belly. The value of x is detected by, for example, a sensor (not shown). The value of x may be set in advance by the user. The value of x, which is an average value for general users, may be set in advance. The detected value of x is stored in the RAM 3, for example. Then, the process proceeds to step S3.

  In step S3, the thumb F1 and the index finger F2 are touched to the image Im1 displayed on the liquid crystal panel 7. With the thumb F1 and the index finger F2, a position instruction operation is performed on two positions on the diagonal line connecting the lower left corner and the upper right corner of the image Im1. When the thumb F1 and the index finger F2 are touched almost simultaneously with the liquid crystal panel 7, the touch panel 5 detects the position coordinates on the liquid crystal panel 7 touched by each finger. The position coordinate of the liquid crystal panel 7 touched by the thumb F1 is A (x1, y1), and the position coordinate of the liquid crystal panel 7 touched by the index finger F2 is B (x2, y2). The detected position coordinates of each finger are converted into signals that can be interpreted by the CPU 1, and the converted signals are supplied to the CPU 1.

  When the thumb F1 and the index finger F2 are moved, the distance between the two points A and B changes. For example, an operation of pinching the image Im1 by moving the thumb F1 and the index finger F2 closer to each other is performed. The distance between the two points is shortened according to the pinching operation. Following the decrease in the distance between the two points, the image Im1 is reduced. The distance between the two points A and B is calculated by the CPU 1 using the position coordinates of the points A and B supplied from the touch panel 5 in real time. Then, the process proceeds to step S4.

  In step S4, it is determined whether or not the distance between AB is equal to or less than a predetermined value w1. The predetermined value w1 is a preset value, and is, for example, 1/3 of the length H in the vertical direction of the image Im1 described with reference to FIG. Note that the distance between ABs may be compared with a relative length instead of the predetermined value w1. For example, you may make it determine whether the distance between AB became 1/3 of the distance between the original AB.

  If it is determined that the distance between AB is not less than or equal to the predetermined value w1, the process returns to step S4 and repeats the determination process of step S4. If it is determined that the distance between AB is equal to or less than the predetermined value w1, the process proceeds to step S5.

  In step S5, a process for reducing the image Im1 is performed. That is, when the distance between AB is equal to or less than the predetermined value w1, the CPU 1 determines that an operation for reducing the image Im1 is performed, and the CPU 1 performs control for reducing the image Im1. For example, the reduced image Im2 that is a similar shape of the image Im1 is displayed in accordance with the rate at which the distance between the two points is shortened. This processing is performed by the digital signal processing unit 4 under the control of the CPU 1. Then, the process proceeds to step S6.

  In step S6, the CPU 1 determines whether or not the distance between the two points is smaller than the predetermined value w2. The predetermined value w2 is a value that makes it difficult to further reduce the image Im1, and is, for example, the value of x described with reference to FIG. If it is determined that the distance between the two points is not smaller than the predetermined value w2, the determination process in step S6 is repeated. If it is determined that the distance between the two points is smaller than the predetermined value w2, the process proceeds to step S7.

  In step S7, a trash can icon Tr is displayed on the liquid crystal panel 7. The trash can icon Tr is displayed in a region without an image that is generated when the image Im1 is reduced. Accordingly, at this stage, the trash can icon Tr and the reduced image Im2 are displayed on the liquid crystal panel 7.

  Here, a display method of the trash can icon Tr will be described. In this embodiment, the trash can icon Tr can be displayed in consideration of operability.

  As shown in FIG. 6, as an example, the liquid crystal panel 7 is divided into four regions with the horizontal direction (x-axis direction) and the vertical direction (y-axis direction) as axes. The upper right area of the liquid crystal panel 7 in the drawing is referred to as a first quadrant, the upper left area is referred to as a second quadrant, the lower left area is referred to as a third quadrant, and the lower right area is referred to as a fourth quadrant. The dividing line of the liquid crystal panel 7 shown in the drawing may or may not be displayed on the screen. The same applies to an arrow indicating an operation to be described later and an arrow indicating an image reduction mode.

  For example, the thumb F1 and the index finger F2 are touched on a diagonal line connecting the lower left corner and the upper right corner of the image Im1. Following the operation of bringing the thumb F1 and the index finger F2 closer, the image Im1 is reduced, and the reduced image Im2 is displayed on the liquid crystal panel 7. At this time, it is assumed that the reduced image Im2 is displayed in the first quadrant, for example. In this embodiment, the trash can icon Tr is displayed in a quadrant different from the quadrant in which the reduced image Im2 is displayed. That is, the trash can icon Tr is displayed in a third quadrant different from the first quadrant. The position where the trash can icon Tr is displayed in the third quadrant is appropriately set so as to have a certain distance from the reduced image Im2.

  The position where the trash can icon Tr is displayed is not limited to the method described above. The trash can icon Tr may be displayed in a direction based on two positions where the thumb F1 and the index finger F2 are touched. Since the thumb F1 and the index finger F2 are touched on the diagonal line connecting the lower left corner and the upper right corner of the image Im1, the trash can icon Tr is displayed in the third quadrant which is the first quadrant and the diagonal quadrant where the reduced image Im2 is displayed. Can also be displayed.

  The quadrant where the trash can icon Tr is displayed may be determined according to the quadrant where the reduced image Im2 is displayed. For example, when the reduced image Im2 is displayed in the third quadrant, the trash can icon Tr is displayed in the fourth quadrant, and when the reduced image Im2 is displayed in the fourth quadrant, the trash can icon Tr is displayed in the third quadrant. You may make it make it. The user may be allowed to set in advance the quadrant in which the trash can icon Tr is displayed. By appropriately setting the quadrant in which the trash can icon Tr is displayed in this manner, the operation of moving the reduced image Im2 in the direction of the trash can icon Tr becomes easy, and the operability is improved.

  Returning to the flowchart shown in FIG. When the trash can icon Tr is displayed in step S7, the process proceeds to step S8. In step S8, the thumb F1 and the index finger F2 are moved while the pinch operation is performed, so that the reduced image Im2 is moved to the vicinity of the trash can icon Tr. Then, it is determined whether or not the distance between the center of gravity c of the reduced image Im2 and the center of the trash can icon Tr is equal to or less than a predetermined value w3. The predetermined value w3 is a value indicating the vicinity of the trash can icon Tr, and is, for example, ½ of the vertical length of the trash can icon Tr.

  If it is determined that the distance between the center of gravity c of the reduced image Im2 and the center of the trash can icon Tr is not less than the predetermined value w3, the process returns to step S8 and repeats the determination process of step S8. If it is determined that the distance between the center of gravity c of the reduced image Im2 and the center of the trash can icon Tr is equal to or less than the predetermined value w3, the process proceeds to step S9.

  In step S9, the preparation state for executing the process corresponding to the operation is displayed. The display of the preparation state is performed by changing the display mode of the display information. For example, the display of the lid of the trash can icon Tr is displayed. By opening the lid of the trash can icon Tr, the user can be notified that the process of deleting the image data is performed. At this time, in addition to opening the lid of the trash can icon Tr, a guide message indicating that the image data is to be deleted may be displayed. Then, the process proceeds to step S10.

  In step S10, it is determined whether or not a cancel operation has been performed. The cancel operation is, for example, an operation of moving the reduced image Im2 that is close to the vicinity of the trash can icon Tr so as to be separated from the trash can icon Tr. That is, an operation in which the reduced image Im2 is returned so that the center of gravity c of the reduced image Im2 and the trash can icon Tr are at a distance greater than a predetermined value w3 while the operation of pinching the image Im1 is performed. If a cancel operation is performed in step S10, the process of deleting the image data is canceled, and the process returns to step S1. When the process returns to step S1, the image Im1 is displayed on the liquid crystal panel 7 instead of the reduced image Im2.

  If it is determined in step S10 that no cancel operation has been performed, the process proceeds to step S11. In step S11, it is determined whether point A or point B can be detected. If it is determined that detection is possible, the process returns to step S10 to determine whether or not a cancel operation has been performed. If it is determined that point A or point B cannot be detected, the process proceeds to step S12.

  In step S12, the reduced image Im2 and the trash can icon Tr are deleted. That is, the case where the point A or the point B cannot be detected means that the operation of pinching the reduced image Im2 is released and the thumb F1 and the index finger F2 are separated from the liquid crystal panel 7. At this time, it is determined that the user has instructed to delete the image data, and the reduced image Im2 and the trash can icon Tr are deleted. Then, a process of deleting the image data of the image Im1 corresponding to the reduced image Im2 from the recording device 6 is performed. Then, the process proceeds to step S13. In step S <b> 13, the next image data is read from the recording device 6 and displayed on the liquid crystal panel 7.

<Modification>
Although one embodiment has been specifically described above, it goes without saying that various modifications can be made in the configuration and processing of the display control device. Hereinafter, a plurality of modified examples will be described.

Modification 1
First, Modification 1 will be described. Modification 1 is a suitable example when the size of the liquid crystal panel is large. FIG. 7 is a display example of the liquid crystal panel 17 in the first modification. The liquid crystal panel 17 is divided into, for example, four regions in the horizontal and vertical directions. Then, it is assumed that the reduced image Im2 is displayed in the first quadrant of the liquid crystal panel 17. Note that the process of reducing the image Im1 displayed on the liquid crystal panel 17 and displaying the reduced image Im2 is the same as that in the above-described embodiment, and thus a duplicate description is omitted.

  A trash can icon Tr is displayed in a region without an image that is generated when the image Im1 is reduced. At this time, if the trash can icon Tr is displayed in a quadrant other than the first quadrant in which the reduced image Im2 is displayed, the distance for moving the reduced image Im2 to the vicinity of the trash can icon Tr may be increased. Therefore, in the first modification, the trash can icon Tr is displayed in the same quadrant where the reduced image Im2 is displayed.

  As shown in FIG. 7, first, a virtual area Is including a reduced image Im2 is set. The virtual area Is is set in the first quadrant where the reduced image Im2 is displayed. The virtual region Is has a similar shape to the liquid crystal panel 17 and has four quadrants like the liquid crystal panel 17.

  At this time, the virtual region Is is set so that the quadrant where the reduced image is displayed on the liquid crystal panel 17 and the quadrant where the reduced image Im2 is displayed in the virtual region Is are in the same quadrant. That is, the reduced image Im2 is displayed in the first quadrant of the liquid crystal panel 17. Therefore, the virtual area Is is set so that the reduced image Im2 is displayed in the first quadrant in the virtual area Is.

  In the virtual area Is, the trash can icon Tr is displayed in a quadrant different from the quadrant in which the reduced image Im2 is displayed. For example, the trash can icon Tr is displayed in the third quadrant of the virtual area Is different from the first quadrant of the virtual area Is. By displaying the trash can icon Tr in this manner, the trash can icon Tr can be displayed at an appropriate position in consideration of operability even when the size of the liquid crystal panel 17 is large.

  Note that the size of the virtual area Is is appropriately set so that the distance between the reduced image Im2 and the trash can icon Tr can be secured a predetermined length or more.

Modification 2
Next, Modification 2 will be described with reference to FIG. In the embodiment and the first modification described above, two points using the thumb F1 and the index finger F2 are designated, and the image is reduced in accordance with an operation of bringing the thumb F1 and the index finger F2 closer. In the second modification, the image is reduced in accordance with a position instruction operation for instructing one place.

  As shown in FIG. 8A, an image Im1 is displayed on the liquid crystal panel 7. For example, a position instruction operation for touching the index finger F2 is performed at a predetermined position in the image Im1. Then, a rotation operation for rotating the index finger F2 in the clockwise direction is performed. The image Im1 is reduced so as to follow the rotation operation of the index finger F2, and a reduced image Im2 is displayed. At this time, as shown in FIG. 8B, a trash can icon Tr is displayed in a region without an image that is generated when the image Im1 is reduced. Further, the cancel operation is performed by rotating the index finger F2 counterclockwise, and the reduced image Im2 is enlarged so as to follow the cancel operation. The rotation direction and the amount of rotation of the index finger F2 can be detected by the CPU 1 based on a signal supplied from the touch panel 5. The CPU 1 controls image reduction and enlargement based on the detection result.

  FIG. 9 is a flowchart illustrating a processing flow in the second modification. The process shown in FIG. 9 is executed under the control of the CPU 1. In step S21, the image Im1 is displayed on the liquid crystal panel 7. Then, the process proceeds to step S22.

  In step S22, it is determined whether an image reduction operation has been performed. The image reduction operation in the second modification is an operation in which one part of the screen Im1 is touched by the index finger F2 and the index finger F2 is rotated clockwise. If it is determined that the image reduction operation has not been performed, the process returns to step S22 and the determination in step S22 is repeated. If it is determined that an image reduction operation has been performed, the process proceeds to step S23.

  In step S23, a process of reducing the image Im1 according to the image reduction operation is performed. The image Im1 is reduced and the reduced image Im2 is displayed on the liquid crystal panel 7. For example, the image Im1 is reduced stepwise according to the amount of rotation of the index finger F2. Then, the process proceeds to step S24. In step S24, a trash can icon Tr is displayed in a region without an image that is generated when the image Im1 is reduced. Then, the process proceeds to step S25. In step S25, a display for opening the lid of the trash can icon Tr is performed. Then, the process proceeds to step S26.

  In step S26, it is determined whether or not a cancel operation has been performed. The cancel operation in the second modification is, for example, an operation that rotates the index finger F2 counterclockwise. If it is determined that a cancel operation has been performed, the process returns to step S21. In step S <b> 21, the image Im <b> 1 is displayed by enlarging the reduced image Im <b> 2 with the cancel operation. If it is determined that the cancel operation has not been performed, the process proceeds to step S27.

  In step S <b> 27, it is determined whether or not one place (point A) designated by the index finger F <b> 2 can be detected on the touch panel 5. If it is determined that detection is possible, the process returns to step S26, and the determination process of step S26 is performed. If it is determined in step S27 that the index finger F2 is released from the liquid crystal panel 7 and it is determined that point A cannot be detected, the process proceeds to step S28.

  It is determined that an instruction to delete the image data is given by an operation in which the index finger F2 is released from the liquid crystal panel 7 without performing a cancel operation. Accordingly, in step S28, a process of deleting the reduced image Im2 and the trash can icon Tr from the liquid crystal panel 7 is performed. Then, the image data of the image Im1 corresponding to the reduced image Im2 is deleted from the recording device 6. Then, the process proceeds to step S29, and the next image data is read from the recording device 6 and displayed.

  Note that the timing for displaying the trash can icon Tr and the timing for opening the lid of the trash can icon Tr may be determined according to the rate at which the image Im1 is reduced. For example, the trash can icon Tr is displayed when the image Im1 is reduced to a first threshold value (for example, 50% of the size of the image Im1) or less. Then, the image Im1 may be further reduced, and displayed when the image Im1 is reduced to a second threshold (for example, 30% of the size of the image Im1) or less so that the lid of the trash can icon Tr is opened.

Modification 3
Next, Modification 3 will be described with reference to FIG. Modification 3 is an example in which, for example, the index finger F2 is used to indicate one location of the image Im1, and the image Im1 is reduced following the movement of the index finger F2. For example, as shown in FIG. 10A, a position indicating operation is performed in which one index finger F2 touches one place near the upper left corner toward the drawing of the image Im1. Then, an operation of moving the index finger F2 diagonally (in the direction of the lower right corner toward the drawing) is performed. Then, as shown in FIG. 10B, the image Im1 is reduced following the movement of the index finger F2, and a reduced image Im2 is displayed. Then, a trash can icon Tr is displayed in a region where there is no image that occurs when the image Im1 is reduced. Of course, the diagonal direction may be set not only from the upper left to the lower right, but also from the upper right to the lower left, from the lower right to the upper left, and from the lower left to the upper right.

  The flow of processing in the third modification is substantially the same as the flowchart shown in FIG. Hereinafter, different points will be mainly described. In the third modification, the image reduction operation in step S22 is an operation of moving one place designated by the index finger F2 in a diagonal direction. Further, the cancel operation in step S26 is different. The cancel operation of the modification 3 is an operation of moving the index finger F2 in a direction opposite to the direction moved to reduce the image Im1. That is, as shown in FIG. 10A, when the index finger F2 is moved from the upper left to the lower right toward the drawing in order to reduce the image Im1, the operation of moving the index finger F2 from the lower right to the upper left is a cancel operation. Other processes are the same as those in the flowchart shown in FIG.

Modification 4
Next, Modification 4 will be described with reference to FIG. As shown in FIG. 11A, an image Im1 is displayed on the liquid crystal panel 7. For example, using the index finger F2, a position instruction operation for touching a predetermined part of the image Im1 is performed. Then, an operation of hitting the liquid crystal panel 7 with the index finger F2 several times (for example, three times) continuously during a predetermined time is performed. Then, as shown in FIG. 11B, the image Im1 is reduced and a reduced image Im2 is displayed. A trash can icon Tr is displayed in a region without an image that is generated when the image Im1 is reduced. In addition, an icon Ba for returning to a region without an image that is generated when the image Im1 is reduced is displayed.

  Note that the image Im1 may be reduced in a stepwise manner in accordance with the number of times of hitting one designated location. The timing at which the trash can icon Tr is displayed and the timing at which the lid of the trash can icon Tr is opened may be determined according to the number of times of hitting one designated location.

  The flow of processing in Modification 4 is substantially the same as the flowchart shown in FIG. Hereinafter, different points will be mainly described. In the fourth modification, the image reduction operation in step S22 is an operation of hitting one portion of the image Im1 designated by the index finger F2. Further, the cancel operation in step S26 is different. The cancel operation in the modification 4 is an operation of touching the return icon Ba. The process in step S27 is a process for determining whether or not the trash can icon Tr has been touched, not whether or not the point A can be detected. That is, if it is determined in step S27 that the trash can icon Tr has been touched, the process proceeds to step S28, and if it is determined that the trash can icon Tr has not been touched, the process returns to step S26. Other processes are the same as those in the flowchart shown in FIG.

Modification 5
Next, Modification 5 will be described with reference to FIG. As shown in FIG. 12A, an image Im1 is displayed on the liquid crystal panel 7. For example, using the index finger F2, a position instruction operation for touching one place on the image Im1 is performed. Then, the position instruction operation is continued for a predetermined time. When the predetermined time elapses, the image Im1 is reduced and the reduced image Im2 is displayed at a predetermined position on the liquid crystal panel 7 as shown in FIG. 12B. A trash can icon Tr is displayed in a region without an image that is generated when the image Im1 is reduced. In addition, an icon Ba for returning to a region without an image that is generated when the image Im1 is reduced is displayed. In this way, the image Im1 can be reduced by continuing the operation of instructing one place on the liquid crystal panel 7 for a predetermined time.

  Note that the image Im1 may be reduced in a stepwise manner in accordance with the duration of the operation for designating one place. The timing at which the trash can icon Tr is displayed and the timing at which the lid of the trash can icon Tr is opened may be determined according to the operation time for instructing one place.

  The flow of processing in Modification 5 is substantially the same as the flowchart shown in FIG. Hereinafter, different points will be mainly described. In the fifth modification, the image reduction operation in step S22 is an operation in which the operation of touching one place of the image Im1 with the index finger F2 is continued for a predetermined time. Further, the canceling operation in step S26 is an operation of touching the return icon Ba in the modified example 5. Further, the process in step S27 is a process for determining whether or not the trash can icon Tr has been touched, not whether or not the point A can be detected. That is, if it is determined in step S27 that the trash can icon Tr has been touched, the process proceeds to step S28. If it is determined that the trash can icon Tr cannot be touched, the process returns to step S26. Other processes are the same as those in the flowchart shown in FIG.

Modification 6
Next, Modification 6 will be described with reference to FIG. As shown in FIG. 13A, an image Im1 is displayed on the liquid crystal panel 7. For example, using the index finger F2, a position instruction operation for strongly pressing one place on the image Im1 is performed. When the position instruction operation is performed, the image Im1 is reduced and the reduced image Im2 is displayed as shown in FIG. 13B. A trash can icon Tr is displayed in a region without an image that is generated when the image Im1 is reduced. In addition, an icon Ba for returning to a region without an image that is generated when the image Im1 is reduced is displayed. Thus, the image Im1 can be reduced by an operation of strongly pressing one place on the liquid crystal panel 7.

  The processing flow in Modification 6 is substantially the same as the flowchart shown in FIG. Hereinafter, different points will be mainly described. In the sixth modification, the image reduction operation in step S22 is a position instruction operation that strongly presses one place on the image Im1. The cancel operation in step S26 is an operation of touching the return icon Ba. The process in step S27 is a process for determining whether or not the trash can icon Tr has been touched, not whether or not the point A can be detected. That is, if it is determined in step S27 that the trash can icon Tr has been touched, the process proceeds to step S28. If it is determined that the trash can icon Tr cannot be touched, the process returns to step S26. Other processes are the same as those in the flowchart shown in FIG.

Modification 7
Next, Modification 7 will be described with reference to FIG. This modification 7 is a modification of the modification 3 described above. In the third modification, the position instruction operation is performed by touching one finger on one place (for example, near the upper left) of the image Im1. In the modified example 7, as shown in FIG. 14A, the position instruction operation is performed by touching two fingers on two points near the upper left corner toward the drawing of the image Im1. For example, the index finger F2 and the middle finger F3 are used as the two fingers. By moving the index finger F2 and the middle finger F3 diagonally, the image Im1 is reduced following the movement of the two fingers, and a reduced image Im2 is displayed.

  The processing flow in the modified example 7 is substantially the same as the flowchart shown in FIG. Hereinafter, different points will be mainly described. In the modified example 7, the image reduction operation in step S22 is an operation of moving the two points designated by the index finger F2 and the middle finger F3 in the diagonal direction. Further, the cancel operation in step S26 is different. The cancel operation of the modified example 7 is, for example, an operation of moving the index finger F2 and the middle finger F3 in the direction opposite to the direction moved to reduce the image Im1. As shown in FIG. 14A, when the index finger F2 and the middle finger F3 are moved from the upper left to the lower right toward the drawing in order to reduce the image Im1, the operation of moving the index finger F2 and the middle finger F3 from the lower right to the upper left is a cancel operation. It is said. In the process in step S27, it is determined whether or not two points indicated by the index finger F2 and the middle finger F3 can be detected. Other processes are the same as those in the flowchart shown in FIG.

  Note that it is also possible to perform the above-described position instruction operation for instructing one or two positions using an operation tool such as a stylus instead of a finger on the liquid crystal panel 7.

Modification 8
Next, Modification 8 will be described with reference to FIG. The modification 8 uses a mouse (not shown) instead of the touch panel 5 as another example of the position input unit.

  As shown in FIG. 15A, an image Im1 and a mouse pointer P are displayed on the liquid crystal panel 7. The mouse pointer P is set to one place on the image Im1. Then, a position indicating operation for indicating one location of the image Im1 is performed by pressing a left button (not shown) provided on the mouse. While holding down the left mouse button, move the mouse so that the mouse pointer P rotates clockwise. Then, as shown in FIG. 15B, the image Im1 is reduced and a reduced image Im2 is displayed. In addition, a trash can icon Tr is displayed in a region where there is no image that occurs when the image Im1 is reduced. Note that the operation for instructing one place of the image Im1 may be an operation for pressing the right button or an operation for pressing the wheel instead of the left button of the mouse. The image Im1 may be reduced according to the rotation operation of the wheel.

  The operation in the modification 8 is substantially the same as the flowchart shown in FIG. Hereinafter, different points will be mainly described. In the image reduction operation in step S22, the mouse pointer P is set at one place on the image Im1, and an arbitrary point on the image Im1 is designated by pressing the left button of the mouse. Then, an operation of moving the mouse while pressing the left button of the mouse is performed so that the mouse pointer P rotates clockwise. The cancel operation in step S26 is an operation of moving the mouse while pressing the left mouse button so that the mouse pointer P rotates counterclockwise.

  In the determination processing in step S27, for example, it is determined whether or not the operation of pressing the left button of the mouse is released. That is, if it is determined that the operation of pressing the left button has been released, the process proceeds to step S28. If it is determined that the left button is pressed, the process returns to step S26. Note that the processing in step S27 may determine whether or not the trash can icon Tr has been clicked. For example, if it is determined that the trash can icon Tr has been clicked by a mouse operation, the process proceeds to step S28. If it is determined that the trash can icon Tr has not been clicked, the process may return to step S26.

Modification 9
Next, Modification 9 will be described with reference to FIG. As shown in FIG. 16A, an image Im1 and a mouse pointer P are displayed on the liquid crystal panel 7.
