As illustrated in FIG. 1, the display processing apparatus 100 includes a storage unit 110, an operation unit 120, a display unit 130, a reading / writing unit 140, and a control unit 150.

  The storage unit 110 appropriately stores data (including a database and the like) used or generated by the control unit 150 during processing, image data read by the control unit 150, and the like. The storage unit 110 is realized by the secondary storage device 111, for example. In the secondary storage device 111, a control program 112, a display image DB (database) 113, and the like are recorded. Programs and data such as the control program 112 and the display image DB 113 are read out to a primary storage device 152 by a CPU (Central Processing Unit) 151 and used and referenced by the CPU 151. The secondary storage device 111 is configured by a storage device such as a hard disk or a flash memory.

  The operation unit 120 receives a user operation and outputs operation data (operation information) corresponding to the received operation to the control unit 150. The operation unit 120 includes a first operation unit 120a that accepts an operation for specifying an image displayed by being switched from an image displayed on the display unit 130 by a user, and an operation for specifying an enlargement area described later by the user. And a second operation unit 120b for receiving. The first operation unit 120a is realized by, for example, the contact sensor 123 shown in FIG. Moreover, the 2nd operation part 120b is implement | achieved by the contact-type sensors 121 and 122 shown in FIG. 2, for example.

  For example, as shown in FIG. 3, the contact sensors 121 to 123 are provided along, for example, a side in the longitudinal direction (lateral direction) or the lateral direction (vertical direction) of the frame of the display unit 130. It is a pressure sensor type touch sensor. The contact sensors 121 to 123 include sensing areas 121a to 123a that are areas for detecting a contact position in a slide operation on the contact sensors 121 to 123 by the user. Here, in the following description, the “slide operation” refers to an operation in which the user moves his / her finger or the like in contact with the sensing areas 121a, 122a, 123a. When the user performs a sliding operation on the sensing areas 121a to 123a, the contact sensors 121 to 123 output operation information indicating positions where the user's fingers or the like are in contact in the sensing areas 121a to 123a. The sensing area 121 a of the contact sensor 121 is provided adjacent to the longitudinal edge of the display panel 132 of the display unit 130. The sensing area 122a of the contact sensor 122 is provided adjacent to the edge of the display panel 132 of the display unit 130 in the short direction. In addition, the sensing area 123a of the contact sensor 123 is an edge in the longitudinal direction of the display panel 132 of the display unit 130, and is provided adjacent to an edge opposite to the edge adjacent to the sensing area 121a.

In addition, the correspondence is recorded in advance in the storage unit 110 so that the position in the sensing area 121a and the position in the longitudinal direction of the sensing area 121a in the image displayed on the display unit 130 coincide with each other. And Similarly, the correspondence relationship is recorded in advance in the storage unit 110 so that the position in the sensing region 122a and the position in the longitudinal direction of the sensing region 122a in the image displayed on the display unit 130 coincide with each other. Shall. Specifically, for example, as shown in FIG. 7, the X axis along the longitudinal direction of the sensing region 121a, the Y axis along the longitudinal direction of the sensing region 122a, and the position in the image displayed on the display unit 130 are shown. Assume that an x-axis and a y-axis for representing are defined. At this time, the position X = X ₁ in the sensing area 121 a corresponds to the x coordinate x = x ₁ in the image displayed on the display unit 130. Further, the position Y = Y ₁ in the sensing area 122 a corresponds to the y coordinate y = y ₁ in the image displayed on the display unit 130.

In addition, as shown in FIG. 7, the sensing area 123 a further includes identifying sensing areas A _{1 to} A _N corresponding to the number N of display image data identified in the display control process described later. Specifying sensing region _A 1 to A _N are respectively a length substantially equal the longitudinal direction of the sensing area 123a.

The input key 124 includes, for example, one or more keys such as an end key used to end image selection and a play / stop key used to start and stop display of a display image.

  The display unit 130 displays an image, an operation screen, and the like based on the image data output from the control unit 150. The display unit 130 is realized by a drive circuit 131 and a display panel 132, for example. The drive circuit 131 drives the display panel 132 according to the image data output from the CPU 151 and causes the display panel 132 to display an image, an operation screen, and the like. The display panel 132 includes a liquid crystal panel, an organic EL (Electro Luminescence) panel, or the like.

  The read / write unit 140 reads and writes data (for example, image data) with respect to the storage medium 40. The read / write unit 140 is realized by, for example, the media controller 141. The media controller 141 reads / writes data from / to the memory card 41.

  The recording medium 40 stores various data. The recording medium 40 records image data that is data representing a captured image (for example, a digital photograph) taken by a digital camera. The recording medium 40 is realized by a memory card 41 composed of a flash memory or the like.

  The control unit 150 controls the entire display processing apparatus 100. The control unit 150 functions as a display image specifying unit 150a, an image specifying unit 150b, a position specifying unit 150c, and an enlarged image generating unit 150d.

  The display image specifying unit 150a functions to specify display image data to be output to the display unit 130 using a plurality of image data stored in the storage medium 40. For example, the display image specifying unit 150a selects an image (hereinafter referred to as a display image) to be displayed on the display unit 130 from among a plurality of image data stored in the storage medium 40 based on the operation information output from the operation unit 120. The display image data to be represented is specified. Then, the display image specifying unit 150a generates the display image DB 113 that stores the specified display image data and the display order of the display images in association with each other, and records the display image DB 113 in the storage unit 110.

  Further, the display image specifying unit 150a divides the sensing area 123a by the number of specified display image data, and defines a plurality of specifying sensing areas. Then, the display image specifying unit 150a records the position in the sensing area 123a in the display image DB 113 in association with the display order for each of the specified plurality of specifying sensing areas.

Here, in the display image DB 113, the display order, the display image data, and the position of the sensing area for specification in the sensing area 123a are recorded in association with each other. FIG. 6 shows an example of the display image DB 113 generated when the display image specifying unit 150a specifies N pieces of display image data. In FIG. 6, “aaa1”, “aaa2”,..., “AaaN” respectively indicate display image data. When these display image data “aaa1”, “aaa2”,..., “AaaN” are output to the display unit 130, the display image represented by each display image data is displayed on the display unit 130. Note that the display image data 113 does not have to be recorded in the display image DB 113. For example, the display image DB 113 may be data composed of an ID of the display image data, a recording location (address) of the display image data, and the like. Further, “Z ₀ ≦ Z <Z ₁ ”, “Z ₁ ≦ Z <Z ₂ ”,..., “Z _N−1 ≦ Z ≦ Z _N ” in FIG. The position of the sensing region for specification when the longitudinal direction is defined as the Z axis is shown.

  The image specifying unit 150b functions to sequentially specify one display image data from a plurality of display image data stored in the display image DB 113 by a slide operation by the user accepted by the first operation unit 120a. Specifically, the image specifying unit 150b refers to the display image DB 113 based on the contact position indicated by the operation information output by the contact sensor 123 by the user's slide operation on the contact sensor 123, and the sensing region for specification. Are sequentially identified, and display image data corresponding to the identified sensing area for identification is sequentially identified.

  The position specifying unit 150c is received by the second operation unit 120b in the display image represented by the display image data specified by the image specifying unit 150b while the image specifying unit 150b sequentially specifies the display image data. It functions as one that sequentially specifies positions corresponding to the slide operation by the user. Specifically, the position specifying unit 150c enlarges an area to be displayed on the display unit 130 for the display images sequentially specified by the image specifying unit 150b by the user's sliding operation on the contact sensor 123. The position is specified sequentially. For example, the position specifying unit 150c performs operations that the contact sensors 121 and 122 output by the user's slide operation on the contact sensors 121 and 122 with respect to the display images represented by the display image data sequentially specified by the image specifying unit 150b. One point is specified as the center point of the enlarged region based on the contact position indicated by the information.

  The magnified image generation unit 150d is a position specified by the position specifying unit 150c in the display image represented by the display image data specified by the image specifying unit 150b while the image specifying unit 150b sequentially specifies display image data. Functions to generate an enlarged image in which the area corresponding to is enlarged and display it on the display unit 130. Specifically, the enlarged image generation unit 150d is configured to display the position specifying unit in the display image represented by the display image data specified by the image specifying unit 150b while the image specifying unit 150b sequentially specifies the display image data. An area having a predetermined size centered on the center point of the enlarged area identified by 150c (for example, a rectangular area having horizontal 320 pixels and vertical 240 pixels) is specified as the enlarged area. Then, enlarged image data for enlarging and displaying the image in the specified enlarged area on the display unit 130 is generated, and the generated enlarged image data is output to the display unit 130.

  The control unit 150 is realized by the CPU 151 and the primary storage device 152, for example. The CPU 151 controls the entire display processing apparatus 100 according to the control program 112 and executes processing. The control program 112 is recorded in the secondary storage device 111 and read out to the primary storage device 152. The CPU 151 executes processing of each function described above of the control unit 150 based on the command of the control program 112 read to the primary storage device 152. A part of the function of the control unit 150 may be realized by various dedicated circuits (for example, an encoder that compresses data, a decoder that decompresses data, and the like). In this case, various dedicated circuits take part of the function of the CPU 151.

  The primary storage device 152 is constituted by, for example, a RAM (Random Access Memory) and functions as a working memory of the CPU 151 or the like. Data used by the CPU 151 during processing and generated data are primarily recorded in the primary storage device 152. Data input / output to / from the CPU 151 is temporarily recorded in the primary storage device 152.

  Next, display control processing executed by the CPU 151 of the control unit 150 will be described with reference to the flowcharts of FIGS. 4 and 5. For example, the display control process starts when the user performs an operation to start the display control process on the display processing apparatus 100 via the operation unit 120. More specifically, for example, the control unit 150 starts when the control unit 150 receives operation information indicating a display control process start instruction output from the operation unit 120.

  When the display control process is started, the display image specifying unit 150a specifies the display image data representing the display image and the display order of the display image data from the plurality of image data recorded in the storage medium 40 ( Step S11). In addition, it is assumed that each image data constituting a moving image and image data representing continuous shot images continuously shot for a predetermined period are recorded in advance in the storage medium 40 as one group, and the display image specifying unit 150a. In this group, the above-described processing is performed using each image data. The display image specifying unit 150a includes all the image data recorded in the storage medium 40 or a plurality of image data in a predetermined group (for example, a plurality of image data recorded in the same folder) recorded in the storage medium 40. Etc. may be used to perform the above-described processing.

  Specifically, for example, the display image specifying unit 150 a acquires shooting time data indicating the shooting time of each image data from the recording medium 40 for all the image data recorded in the storage medium 40. In the storage medium 40, it is assumed that image data and shooting time data indicating the time when the image data was shot are recorded in association with each other. Then, the order of the shooting times indicated by the acquired shooting time data (that is, the chronological order) is associated with the display order, and the image data corresponding to the shooting time data is recorded in the display image DB 113 as display image data.

  Further, the display image specifying unit 150a divides the sensing area 123a by the number of display image data specified in step S11, and defines a plurality of specifying sensing areas (step S12).

Specifically, when N pieces of display image data are recorded in the display image DB 113, the display image specifying unit 150a specifies the sensing region 123a by dividing it into N parts in the longitudinal direction as shown in FIG. defining a use sensing region _a 1 to a _N. The position on the sensing region 123a of specifying sensing region _A 1 to A _N ( _{"Z 0} ≦ _{Z <Z 1", "Z 1} ≦ _{Z <Z 2",} ..., _{"Z N-1 ≦ Z ≦ Z} N ") Is recorded in the display image DB 113 in association with the display order n (see FIG. 6).

  Next, the enlarged image generation unit 150d determines whether or not the user has performed an operation to start displaying the display image represented by the display image data specified in Step S11 on the display unit 130 (Step S13). ). Specifically, the enlarged image generation unit 150d determines whether or not operation information indicating an instruction to start displaying a display image output from the operation unit 120 is received by the user operating the operation unit 120. When it is determined that the user has not performed an operation for starting display (step S13; No), the enlarged image generation unit 150d is in a waiting state until an operation for starting display is performed.

  When it is determined that the user has performed an operation to start display (step S13; Yes), the enlarged image generation unit 150d refers to the display image DB 113 and displays display image data corresponding to the display order n = 1. The data is output to the unit 130 (step S14).

  Next, the control unit 150 (in particular, the image specifying unit 150b, the position specifying unit 150c, and the enlarged image generating unit 150d) executes an enlarged image generating process (step S15). The enlarged image generation process will be described with reference to the flowchart of FIG.

  First, the image specifying unit 150b determines whether or not a user's contact operation on the contact sensor 123 has been detected (step S21). Specifically, the image specifying unit 150b determines whether or not operation information indicating a position where the user performs a contact operation on the sensing area 123a from the contact sensor 123 is received. If it is determined that the contact operation is not detected (step S21; No), the image specifying unit 150b is in a waiting state until the contact operation is detected.

  When it is determined that the contact operation has been detected (step S21; Yes), the image specifying unit 150b displays the display image data corresponding to the position touched by the user based on the operation information received from the contact sensor 123 by the contact operation. Is specified (step S22).

Specifically, the image specifying unit 150b refers to the display image DB 113 based on the position on the sensing area 123a indicated by the operation information received from the contact sensor 123, and among the specifying sensing areas A _{1 to} A _N. From this, a contact area _Am (1 ≦ m ≦ N), which is an area where the user has contacted, is specified. Then, display image data corresponding to the display order n = m is specified. For example, if the position Z on the sensing region 123a indicated by the operation information received from the contact sensor 123 is _{Z 2} ≦ Z _{<Z 3,} the image selecting unit 150b refers to the display image DB 113, the contact area _{A m} As a specific sensing area A ₃ (ie, m = 3). Then, the display image data “aaa3” corresponding to the display order n = 3 is specified (see FIG. 6).

  Next, the position specifying unit 150c determines whether or not the user's contact operation on the contact sensors 121 and 122 has been detected (step S23). Specifically, the position specifying unit 150c determines whether or not operation information indicating a position where the user performs a contact operation on the sensing areas 121a and 122a has been received from the contact sensors 121 and 122. If it is determined that the contact operation is not detected (step S23; No), the position specifying unit 150c returns the process to step S21.

When it is determined that the user's contact operation with respect to the contact sensors 121 and 122 has been detected (step S23; Yes), the position specifying unit 150c receives the operation information received from the contact sensor 121 by the contact operation, and the contact sensor 122. The center point P ₀ of the enlarged region B is specified based on the operation information received from (Step S24).

A specific example of a method for specifying the center point P ₀ of the enlarged region B will be described with reference to FIG. FIG. 8A shows a display image I _0n represented by display image data corresponding to the display order n. Note that the display image I _0n shown in FIG. 8A is for explaining a method of specifying the center point P ₀ of the enlarged region B, and the image actually displayed on the display unit 130 is shown in FIG. It is an enlarged image I _1n (see FIG. 8B) of the enlarged region B in (a). As illustrated in FIG. 8A, the position specifying unit 150 c includes the coordinate x ₀ in the x-axis direction on the display image I _0n corresponding to the position X ₀ indicated by the operation information from the contact sensor 121, and the contact type. One coordinate point defined from the coordinate y ₀ in the y-axis direction on the display image I _0n corresponding to the position Y ₀ indicated by the operation information from the sensor 122 is specified as the center point P ₀ of the enlarged region B.

Then enlarged image generating unit 150d generates an enlarged image data of the enlarged area B which is specified by the center point P _0, which is specified in step S24, and outputs the generated magnified image data on the display unit 130 (step S25 ).

Specifically, the enlarged image generating unit 150d, an area having a predetermined size around the center point P _0, which is specified in step S24 (e.g., 320 horizontal pixels, a rectangular area of 240 vertical pixels) larger region B As specified. Note that the size of the enlarged area B is set in advance by the user and recorded in the storage unit 110, for example. Then, the enlarged image generation unit 150 d generates enlarged image data for enlarged display on the display unit 130 for the specified enlarged region B, and outputs the enlarged image data to the display unit 130. For example, when the enlarged image data generated for the enlarged region B on the display image I _0n shown in FIG. 8A is output to the display unit 130, the enlarged image I _1n shown in FIG. Is displayed. Then, the enlarged image generation unit 150d returns the process to step 21.

  Then, the control unit (the image specifying unit 150b, the position specifying unit 150c, and the enlarged image generating unit 150d) repeats the processes of steps S21 to S25. Note that the control unit 150, for example, when the user performs an operation to end display image display via the operation unit 120, that is, when operation information indicating a display image display end instruction is received from the operation unit 120. The display control process ends.

  Next, with respect to the display processing apparatus 100 configured as described above, specific operations when an enlarged display is performed while switching a plurality of images selected in advance by the user will be described with reference to FIGS. I will explain. FIG. 9 and FIGS. 10A to 10C are diagrams for explaining the movement of the enlarged region by the user's operation and the switching of the original image to be enlarged. FIGS. 10D to 10F are diagrams showing enlarged images displayed on the display unit 130 by the user's operation described in FIGS. 10A to 10C. Here, by the user's operation, a plurality of pieces of image data constituting a moving image are recorded in advance in the display image DB 113 as display image data, and the oldest shooting time of the display image data is displayed as the display order. To do.

As shown in FIG. 9, the display processing apparatus 100 is configured to sequentially switch and enlarge the display images I ₀₁ , I ₀₂ ,..., I _0N represented by the N pieces of display image data by a touch operation of the sensing area 123 a by the user. Specified as an image. Further, an enlarged region of the image specified by the contact operation of the sensing region 123a is specified by the contact operation of the sensing regions 121a and 122a performed simultaneously with the contact operation of the sensing region 123a by the user, and the enlarged image is displayed. For example, the user, to the position _{X n} from the position _{X 1} for sensing area 121a, the position _{Y 1} to position _{Y n} for sensing area 122a, to the position _{Z n} from the position _{Z 1} for sensing area 123a, the sensing area 121a, 122a, The case where the slide operation on 123a is performed simultaneously will be described. At this time, the display processing unit 100 first sensing area 121a, and displays the enlarged image of the enlarged area _{B 1} in the display image _{I 01} identified by 122a of the contact operation. And while displaying the enlarged image which moved the enlarged area about the display image specified by the contact operation of the sensing area 123a, the enlarged image of the enlarged area _Bn in the display image I _0n is finally displayed.

Next, a more specific operation of the display processing apparatus 100 will be described with reference to FIGS.
For example, as shown in FIG. 10A, the user touches the left index finger, the left thumb index, and the right index index finger at positions X _a , Y _a , and Z _a on the sensing areas 121 a, 122 a, and 123 _a , respectively. . At this time, the display processing unit 100, the display image data corresponding to the position _{Z a} in the sensing region 123a, is specified by referring to the display image DB 113. Then, the display processing device 100 specifies the enlarged region B _a centered on the point X _0a specified by the position X _a on the sensing region 121a and the position Y _a on the sensing region 122a. Then, the display processing unit 100 generates an enlarged image data of the enlarged area B _a in the display image I _0a representing specific display image data, and outputs to the display unit 130. Accordingly, the enlarged image _I1a shown in FIG. 10D is displayed on the display unit 130 by the operation shown in FIG.

Next, a different area is enlarged and displayed on the display unit 130 for the display image that is newer than the time when the original image (that is, the display image I _0a ) of the enlarged image I _1a in FIG. The operation for making it happen will be described. In this case, the user performs the slide operation with the left index finger, the left thumb, and the right index finger simultaneously from the position X _a , Y _a , Z _a to the position X _b , Y _b , Z _b as shown in FIG.

The x coordinate of the center point P ₀ of the enlarged region B in the original image (image before enlargement) of the enlarged image displayed on the display unit 130 is specified (step S33). Then, the position specifying unit 150e records the specified x coordinate in the primary storage device 152. A specific method for obtaining the x coordinate of the center point of the enlarged region B based on the operation information received from the contact sensor 121 is the same as that in the first embodiment.

  The position specifying unit 150e determines whether or not the user's contact operation on the contact sensor 122 has been detected (step S37). Specifically, the position specifying unit 150e determines whether or not operation information indicating a position where the user performs a contact operation on the sensing area 122a is received from the contact sensor 122.

When it is determined that the contact operation of the user with respect to the contact sensor 122 is detected (step S37; Yes), the position specifying unit 150e is based on the contact position indicated by the operation information received from the contact sensor 122 by the contact operation. The y coordinate of the center point P ₀ of the enlarged area B in the original image of the enlarged image displayed on the display unit 130 is specified (step S38). Then, the position specifying unit 150e records the specified y coordinate in the primary storage device 152. A specific method for obtaining the y coordinate of the center point of the enlarged region B based on the operation information received from the contact sensor 122 is the same as that in the first embodiment.

  When it is determined that the user's contact operation with respect to the contact sensor 122 is not detected (step S37; No), the position specifying unit 150e has detected the user's contact operation with respect to the contact sensor 122 within the latest past predetermined time. Whether or not (step S39). Specifically, for example, it is determined whether or not the operation information is received from the contact sensor 122 within the latest past predetermined time (for example, within 100 msec). If it is determined that the user's contact operation on the contact sensor 122 has not been detected within the most recent past predetermined time (step S39; No), the position specifying unit 150e advances the process to step S41.

When it is determined that the user's touch operation on the contact sensor 122 has been detected within the latest past predetermined time (step S39; Yes), the position specifying unit 150e is based on the operation information received within the latest past predetermined time. , it calculates the moving speed of the y-axis direction of the center point P ₀ of the enlarged area B in the original image of the enlarged image displayed on the display unit 130 (step S40). Specifically, regarding the position in the sensing area 122a indicated by a plurality of operation information received within the latest past predetermined time (for example, within 100 msec), on the original image of the enlarged image displayed on the corresponding display unit 130 Is determined, that is, the y-coordinate of the center point P ₀ , and the moving distance within the latest past predetermined time is calculated. Then, the y-axis direction moving speed of the center point immediately before the end of the contact operation by the user is calculated from the calculated moving distance and the latest past predetermined time. Further, the position specifying unit 150e records the calculated y-axis direction moving speed in the primary storage device 152.

Then, the position specifying unit 150e from the primary to the storage device 152 records the y-axis direction moving speed, identifies the y-coordinate after movement of the center point _{P 0} (step S41). Specifically, the position specifying unit 150e, based on the y-coordinate of the primary storage device 152 y-axis direction movement speed and the center point P ₀ recorded in the center point P ₀ is recorded in the primary storage device 152 The y-coordinate is calculated when moving at a constant speed at the moving speed in the y-axis direction. Then, the position specifying unit 150e records the calculated y coordinate in the primary storage device 152.

Next, the enlarged image generating unit 150d includes, x coordinate of the center point P ₀ of the enlarged region B which is recorded in the primary storage device 152, based on the y-coordinate, and generates an enlarged image data, the generated magnified image data It outputs to the display part 130 (step S42).

Then, the enlarged image generating unit 150d generates enlarged image data in the specified enlarged region B, and outputs it to the display unit 130. Then, the enlarged image generation unit 150d returns the process to step 32.

  Then, the control unit 150 (the position specifying unit 150e and the enlarged image generating unit 150d) repeatedly performs the processes in steps S32 to S42. Note that the control unit 150, for example, when the user performs an operation to end display image display via the operation unit 120, that is, when operation information indicating a display image display end instruction is received from the operation unit 120. The display control process ends.

  Next, with regard to the configuration display processing apparatus 100 configured as described above, specific operations when the user moves the enlarged region with respect to the enlarged image displayed on the display unit 130 are illustrated in FIGS. ). FIGS. 14A and 14B are diagrams for explaining the movement of the enlarged region, and an enlarged image in the enlarged region is actually displayed on the display unit 130. FIG.

When the user wants to move the area to be enlarged, the user performs a sliding operation on the sensing areas 121a and 122a of the contact sensors 121 and 122 according to the direction and distance to be moved. In response to this operation, the center point of the enlarged area moves, so that the enlarged area can be moved. For example, as shown in FIG. 14 (a), when a user's finger to the position of X ₁ of the sensing area 121a, the user slid over the sensing area 121a toward the X _2, the enlarged region B ₁ is moved to the position of the enlarged region _{B 2.} Thus, the enlarged image displayed on the display unit 130 also changes in accordance with the movement of the enlarged region B ₁ to enlarged region B _2. Further, after the user has slid to move the finger from X ₁ of the sensing area 121a to the position of X _2, if the finger is released from the sensing area 121a, expansion region, the moving speed at the position of the enlarged region B ₂ moves in the direction of arrow b ₃ while maintaining. Further, with the enlarged region is moving in the direction of arrow b _3, as shown in FIG. 14 (b), when a slide operation is moved to the position of Y ₅ from the position of Y ₄ in the sensing area 122a, expanded region moves diagonally from the position of the enlargement area B ₄ to the position of the enlargement area B _5. This is because the moving speed in the x-axis direction is maintained. And if further releases the finger position of Y ₅ sensing regions 122a, enlarged region is moved in the direction of arrow b ₆ while maintaining the moving speed at the position of the enlargement area B _5. In addition, when it is desired to stop the movement of the enlarged area, the movement of the enlarged area is stopped when the user stops the finger without performing a sliding operation on the sensing areas 121a and 122a of the contact sensors 121 and 122. To do.

  As described above, in the display processing apparatus 100 according to the second embodiment, the user selects two enlarged areas provided along the frame of the display unit 130 in the operation of selecting the enlarged region of the enlarged image displayed on the display unit 130. An arbitrary position can be selected as an enlarged region by the contact sensors 121 and 122. When the user lifts his / her finger from the contact sensors 121 and 122, the enlarged region moves at a constant speed at a speed corresponding to the operation up to that point. Therefore, the user can move the enlarged region with various changes, and can give a new impression to the user.

In addition, this invention is not limited to said embodiment, A various deformation | transformation and application are possible. For example, in the above-described embodiment, two touch sensors that detect one-dimensional position information are used as the contact sensors 121 and 122, but the present invention is not limited thereto. For example, the two-dimensional position information may be acquired by using a transparent touch panel sensor disposed on the display panel 132. In this case, the coordinates on the display image corresponding to the position touched by the user may be specified as the center point P ₀ of the enlarged region B. Further, the number of touch sensors provided along the edge of the display panel 132 is not limited to two, and three or more touch sensors may be provided along the edge of the display panel 132.

  In the first embodiment, the contact sensor 123, which is the first operation unit 120a for accepting the operation of switching the display image, is provided along the longitudinal edge of the display panel 132. However, the location is limited to this. Absent. For example, the display panel 132 may be provided on the lateral edge of the display panel 132 or on the side surface of the frame of the display unit 130. In the above embodiment, an example in which the contact sensor 123 is used as an example of the first operation unit 120a has been described, but the present invention is not limited thereto. For example, the first operation unit 120a may be configured with hard keys such as buttons and cross keys.

  Further, in the display processing device 100 according to the first embodiment, the enlarged region may move at a constant speed after the user's operation, like the display processing device according to the second embodiment. That is, the position specifying unit 150c according to the first embodiment may further function as the position specifying unit 150e according to the second embodiment. Specifically, the position specifying unit 150c according to the first embodiment performs the processes shown in steps S32 to S41 in FIG. 13 performed by the position specifying unit 150e according to the second embodiment, instead of steps S23 and S24 in FIG. That's fine. By performing such processing, the position specifying unit 150c calculates an operation speed based on the user's contact operation on the contact sensors 121 and 122. Then, the position specifying unit 150c calculates an enlarged region in the display image represented by the display image data specified based on the user's contact operation on the contact sensor 123 after the user's contact operation on the contact sensors 121 and 122 is completed. The position of the enlarged area after movement is specified when the movement is performed at a constant speed at the moving speed. Then, the enlarged image generation unit 150d generates enlarged image data in the enlarged area after movement, and outputs it to the display unit 130.

  Note that the display processing apparatus 100 according to the embodiment of the present invention can be realized by using a normal computer system without using a dedicated apparatus. For example, the above-described processing is executed by installing the program from a medium (flexible disk, CD-ROM, DVD-ROM, etc.) storing the program for executing the above-described processing in a computer equipped with a network card or the like. A display processing device can be configured.

  In addition, a method for supplying the program to the computer is arbitrary. For example, you may supply via a communication line, a communication network, a communication system, etc. For example, the above-described processing can be executed by posting the program on a bulletin board (BBS) of a communication network and distributing it on a carrier wave via the network.
