Description

  The present invention relates to a window system incorporated in an embedded device having a liquid crystal display device such as a digital camera or a digital video, and pointing to focus a window such as a touch panel when performing an operation on an arbitrary window displayed on the liquid crystal display device. The present invention relates to a built-in window system control apparatus that has an operation mode using only a device and an operation mode using only a hard key group, and which can dynamically switch between two operation modes.

  Conventionally, many embedded devices that have a liquid crystal display device such as a digital camera or a digital video and have a built-in window system generally do not have a pointing device such as a mouse or a touch panel. An operation for an arbitrary window displayed on the apparatus has been realized.

However, recently, products having a liquid crystal touch panel device, such as a transparent touch panel superimposed on a liquid crystal display device, are becoming common. In a product having such a pointing device, a button or the like is displayed on a liquid crystal touch panel device and a user touches the button (see Patent Documents 1 and 2 below).
JP 11-252427 A JP-A-11-289484

  However, the above method has the following problems.

  a) In a mode in which a user has a pointing device, displays a button or the like on a liquid crystal touch panel device, and operates by touching the user, the size of the button or the like must be a size that can be selected by a human finger. This means that when a button or the like is to be displayed simultaneously with the captured image preview, the display area is compressed.

  b) In a mode in which a user has a pointing device, displays buttons on a liquid crystal touch panel device, and is operated by touching by a user, the operation specification is not compatible with a product operated only by a conventional hard key group.

  An object of the present invention is to solve these problems and use only an operation mode using only a pointing device such as a touch panel and a hard key group when performing an operation on an arbitrary window displayed on a liquid crystal display device. To provide a built-in window system control device having an operation mode and capable of dynamically switching between two operation modes.

In order to solve the above-mentioned problem a), the present invention relates to a built-in window system control device, and relates to a key code input from a hard key, correspondence information between a key code and a window, The key input dispatch mechanism that activates the window processing function corresponding to the input key code from the corresponding information of the window and the window processing function, and the window that holds the coordinates specified by the pointing device and the correspondence information between the coordinates and the window. A pointing device input dispatch mechanism that activates a window processing function corresponding to a specified coordinate, and one of these two mechanisms is enabled and the other is disabled from management information and corresponding information of the window and the window processing function. An operation mode change mechanism with an exclusive switching function And Bei,
The operation mode is switched as necessary by the operation mode change mechanism, and when the operation mode is the hard key input mode, if there is an input from the hard key, the corresponding window registered in advance corresponding to the input key code Invoke the processing function. In addition, when the operation mode is the pointing device input mode, if there is a coordinate designation input from the pointing device, the window processing function of the corresponding window corresponding to the input coordinate is activated.

  By providing the above mechanism, the operation mode is normally set to the pointing device input mode, and if you want to secure a large display area to display the captured image preview on the liquid crystal touch panel device, select the operation mode as a hard key. Set to input mode. As a result, it is possible to expand the display area without displaying buttons and the like for operation on the liquid crystal touch panel device at the same time as the image preview (solution of problem a).

Further, in order to solve the above-mentioned problem b), the present invention has a function of enabling the two mechanisms of the key input dispatch mechanism and the pointing device input dispatch mechanism at the same time. The operation mode change mechanism
By enabling both the key input dispatch mechanism and the pointing device input dispatch mechanism at the same time by the operation mode change mechanism, when there is an input from a hard key, it is registered in advance according to the input key code. Invoke the window processing function for the window. At the same time, when there is a coordinate designation input from the pointing device, the window processing function of the corresponding window corresponding to the inputted coordinate is activated.

  By providing the above mechanism, even if a user has a pointing device, displays buttons, etc. on the liquid crystal touch panel device and operates by touching by the user, if there is an input from a hard key, Correspondingly, the window processing function of the corresponding window registered in advance is started. As a result, it is possible to maintain the compatibility of the operation specifications with the product operated only by the conventional hard key group (solution of the problem b)).

As described above, according to the present invention, the hard key input and the pointing device input are limited by the operation mode changing mechanism 410 that allows the operation mode to be switched and received exclusively at an arbitrary timing. The display area of the liquid crystal touch panel device can be used effectively, and the cost can be reduced.
Further, by effectively using the operation mode changing mechanism 410, an unprecedented GUI can be realized, and improvement in user operability can be expected.

  Furthermore, in order to implement the present invention, there is no need to newly develop dedicated hardware, and it can be easily incorporated into a standard window system. Can be improved.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the present invention will be described below based on an embodiment with reference to the drawings.

  In the first embodiment of the present invention, a method for realizing means for solving the problems a) and b) will be described.

  In FIG. 1, the ROM 220 includes a startup code, a window 1 processing function 310, a window 2 processing function 330, and an initialization program for the embedded window system control apparatus 400. When the CPU 210 is reset, the initialization program is executed on the RAM. The initialization program copies the embedded window system control device 400, the window 1 processing function 310, and the window 2 processing function 330 onto the RAM 300, and starts up the window system. Further, the window 1 (320) and the window 2 (340) are generated on the embedded window system control device 400. At this time, the window 1 processing function 310 and the window 2 processing function 330 become operable in response to the key input events 401 and 405 or the pointing device input events 431 and 432.

  The window 1 processing function 310 and the window 2 processing function 330 call (407 or 409) the drawing mechanism 460 as necessary. The drawing mechanism 460 issues a drawing command 404 to the VRAM 230 only for necessary portions while referring to the window clipping information 403 that has started the drawing mechanism 460 from the window management information 402. The drawing result in the VRAM 230 is reflected on the liquid crystal display device (liquid crystal touch panel device) 600.

  Similarly, the window 1 processing function 310 and the window 2 processing function 330 can call (406 or 408) the operation mode changing mechanism 410 as necessary, including at the time of initialization. The operation mode change mechanism 410 enables or disables the input from the hard key group 500 by enabling or disabling the hard key input mode using the operation mode change command 411, and inputs a pointing device using the operation mode change command 412. By enabling or disabling the mode, input from the liquid crystal touch panel device 600 can be permitted or prohibited.

  The hard key group 500 is an input device such as a button or a keyboard that generates key codes from 0 to 255. When an arbitrary key code 501 is input from the hard key group 500, the key input dispatch mechanism 470 is activated. The key input dispatch mechanism 470 obtains the corresponding window from the key code / window correspondence information 420 for the key code 501 that is input only when the hard key input mode is set to be valid by the operation mode change mechanism 410. Further, the corresponding window processing function is called (401 or 405) from the correspondence information 450 between the corresponding window and the window processing function.

  The liquid crystal touch panel device 600 is an input device that designates coordinates with a finger or the like. When an arbitrary pointing device coordinate 603 is input from the liquid crystal touch panel device 600, the pointing device input mechanism 480 is activated. Only when the pointing device input mode is set to be valid by the operation mode changing mechanism 410, the pointing device input mechanism 480 determines the coordinates, the corresponding window, and the window processing function from the window management information 402 for the input pointing device coordinates 603. The corresponding window processing function is called (431 or 432) from the corresponding information 433.

  As a result, when the pointing device input mode is normally enabled by the operation mode changing mechanism 410 and a large display area is to be displayed on the liquid crystal touch panel device 600 so as to display the captured image preview, the operation mode is changed. The mechanism 410 disables the pointing device input mode and enables the hard key input mode. Accordingly, it is possible to widen the display area without displaying buttons and the like for operation on the liquid crystal touch panel device 600 at the same time as the image preview (solution of the problem a).

  Also, by enabling both the pointing device input mode and the hard key input mode simultaneously by the operation mode changing mechanism 410, the pointing device has a pointing device, and the user touches the liquid crystal touch panel device by displaying buttons and the like. Even if the operation is performed by the above, when there is an input from a hard key, the window processing function of the corresponding window registered in advance can be activated in accordance with the input key code. As a result, it is possible to maintain the compatibility of the operation specifications with the product operated only by the conventional hard key group (solution of the problem b)).

  Embodiment 1 of the present invention will be described below in detail with reference to the drawings.

  FIG. 2 is a diagram showing the correspondence information 420 between the key code and the window in FIG. A window identifier can be obtained corresponding to the key code. For example, the key code array [0] corresponds to the window 1 (421), and the key code array [1] corresponds to the window 2 (422). Since the window identifier corresponding to the key code array [2] is “FALSE”, the input of the key code “2” is ignored.

  FIG. 3 is a diagram showing correspondence information 450 between the corresponding window and the window processing function in FIG. A window processing function 454 can be obtained corresponding to the window identifier 451. For example, the window processing function of the window array [0] corresponding to the window 1 (452) is WinProc1 () 455, and the window processing function of the window array [1] corresponding to the window 2 (453) is WinProc2 () 456. is there.

  FIG. 4 is a diagram showing the correspondence information 433 of the coordinates, the corresponding window, and the window processing function in FIG. The window structure is managed by being connected in a list structure from the top (front side) of the Z order. If the pointing device coordinates 603 are X and Y, the window is traced from the window identifier head pointer 440, and the X and Y coordinates are set in a rectangular area consisting of x coordinates 442, y coordinates 443, width 444, and height 445, which are members of the window structure. Is included, the corresponding window processing function 446 can be obtained.

  FIG. 5 is a flowchart showing the key input dispatch mechanism 470. First, it is determined whether the hard key input mode is valid (step 471). If the hard key input mode is invalid, the process is terminated without doing anything. If the hard key input mode is valid in step 471, the input key code is substituted for x (step 472). Next, the corresponding window identifier is obtained by substituting the key code array [x] of the key code / window correspondence information 420 into y (step 473). Next, it is determined whether y (corresponding window identifier) is equal to FALSE (step 474). If they are equal in step 474, the processing is terminated without doing anything. If they are not equal in step 474, the following processing is repeated from z = 0 to the upper limit of the corresponding information 450 of the corresponding window and window processing function (step 475).

  It is determined whether the window identifier which is a member of the window array [z] of the correspondence information 450 of the corresponding window and the window processing function is equal to y (corresponding window identifier) obtained in step 473 (step 476). If equal in step 476, the window processing function that is a member of the window array [z] of the correspondence information 450 of the corresponding window and window processing function is activated (step 478). If they are not equal in step 476, z is incremented (step 477).

  FIG. 6 is a flowchart illustrating the pointing device input dispatch mechanism 480. First, it is determined whether the pointing device input mode is valid (step 481). If the pointing device input mode is invalid, the process ends without doing anything. If the pointing device input mode is valid in step 481, the pointing device coordinates 603 are set in X and Y (step 482). Next, the window identifier head pointer (440) is set to p by referring to the correspondence information 433 of the coordinates, the corresponding window, and the window processing function (step 483). Next, it is determined whether p is NULL (step 484). If p is NULL, the process ends without doing anything. If p is not NULL in step 484, the correspondence information 433 of the coordinates, the corresponding window, and the window processing function is referred to, and the coordinates indicated by X and Y are p-> x coordinates, p-> y coordinates, p-- It is determined whether it is included in the rectangular area indicated by> width, p-> height (step 485). When the coordinates indicated by X and Y are included in the rectangular area indicated by p-> x coordinate, p-> y coordinate, p-> width, p-> height, the coordinates, corresponding window, and window processing function Referring to the correspondence information 433, the p-> window processing function is activated and the processing is terminated (step 486). In step 485, if the coordinates indicated by X, Y are not included in the rectangular area indicated by p-> x coordinate, p-> y coordinate, p-> width, p-> height, the corresponding coordinates With reference to the correspondence information 433 of the window and the window processing function, p-> next pointer is set to p (step 487), and the processing returns to step 484.
