Abstract

An image processing apparatus capable of avoiding abnormal termination at startup by preventing a setting value that induces abnormal termination from being read at startup.
The image processing apparatus acquires a flag stored in a storage area in advance as to whether or not the processing for the image data has ended abnormally, and from the acquired flag, at the end of the previous processing of the image data. It is determined whether the process has ended normally or abnormally. Then, at the time of activation, if the determination result is abnormal termination, the setting parameter of the processing for the image data stored in the storage area in advance is changed.

Description

  The present invention relates to an image processing device, an image processing method, and an image processing program, and more particularly to an image processing device, an image processing method, and a preprocessing program for processing digital image data obtained by photographing with a digital camera.

  Images taken with a digital camera can be viewed and edited using an image processing application installed in a personal computer or the like. In general, when the number of pixels of an image is large, a lot of time is required for image processing and display, and the usability of the application may deteriorate. The application has made various efforts to prevent this.

  Many image processing applications are provided with a plurality of setting items relating to display methods and image processing. Each setting value is saved at any time, and when the application is next started, the setting at the previous termination is automatically reflected.

  FIG. 2 shows an operation example of the application when the set value is changed.

  In the operation shown in FIG. 2A, when the setting value is changed by the user, first, image processing is performed using the changed setting value. After the image processing is completed, the changed setting value is saved, and the processed image is displayed on the GUI. In the operation illustrated in FIG. 2A, the user cannot perform an operation until the application finishes image processing. In particular, when the number of pixels of the image is large, the user is kept waiting for a long time, and the user response is lowered.

  In order to prevent this, a method of processing a plurality of processes in parallel is known. In the operation shown in FIG. 2B, the application uses two threads, a main thread and a sub thread. The main thread performs image display on the GUI and response processing for user operations. The sub thread performs image processing.

  When the setting value is changed by the user in the main thread, the changed setting value is first saved. Next, in the sub thread, the stored setting value is referred to, and the image is processed using the setting value. Meanwhile, the main thread displays an image before processing on the GUI and accepts an operation by the user.

  When the image processing is completed in the sub thread, the processed image is displayed on the GUI. With such an operation, the user can perform an operation even during image processing, and the user response is improved.

  In the image processing application as described above, when an image is processed using a set value, the application may cause an unexpected operation and end improperly. This can occur particularly when a file that can be freely created externally is read and used, such as when a profile is read.

  If the application terminates improperly, the values set by the user will be lost. Therefore, when starting up next time, in order to obtain the same image as the previous time, the user has to input the set value again from the beginning, which is very troublesome. In order to improve this, every time the setting value is changed by the user, the changed setting value may be saved, and then image processing may be performed.

  However, as described above, in general, when an image processing application is started, the stored setting value is read to attempt to reproduce the state at the previous end. In addition, in order to speed up the operation of the application, information that may be used by the application, such as an ICC profile, may be acquired at the time of activation even if the information is unnecessary at the time of activation.

  If the setting value is saved before the image processing is completed, if the application is terminated abnormally, the setting value that caused the abnormal termination is stored. At the next startup, the set value is used, and the application terminates illegally during startup.

  In order to avoid this state, the user must reinstall the application himself or rewrite the stored setting item, which takes a lot of time and effort for the user. In addition, when the setting value is stored in the Windows (registered trademark) registry, the user may delete an erroneous item.

On the other hand, a technique has been proposed in which whether or not a lens unit such as a digital camera has ended abnormally is managed by a flag, and if it ends abnormally, the lens is returned to the initial position at the next start (Patent Document 1). .
JP 2006-058818 A

  However, in the above-mentioned patent document 1, since the state is always returned to the initial state at the time of activation, when the user does not want to lose the value set last time, or when measures are taken to avoid the abnormal state by itself, The set value will be initialized.

  Therefore, the present invention provides an image processing apparatus, an image processing method, and an image processing program that can avoid an abnormal end at the time of starting by preventing a setting value that induces an abnormal end from being read at the time of starting. Objective.

  In order to achieve the above object, an image processing apparatus according to the present invention includes a parameter setting unit that sets a processing parameter for image data, a parameter storage unit that stores a parameter set by the parameter setting unit, and the parameter storage unit. Flag storage means for storing a flag indicating whether or not the processing for the image data performed based on the parameter stored by the means has ended abnormally, and flag acquisition means for acquiring the flag stored by the flag storage means, Abnormal end determination means for determining whether the processing has been completed normally or abnormally at the end of processing of the previous image data from the flag acquired by the flag acquisition means, and the abnormal end determination at startup When the determination result by the means is determined to be abnormal termination, the parameter stored by the parameter storage means is Wherein the startup parameter changing means for changing over data, further comprising.

  The image processing method of the present invention is based on a parameter setting step for setting processing parameters for image data, a parameter storage step for storing parameters set by the parameter setting step, and the parameters stored by the parameter storage means. A flag storing step for storing a flag indicating whether or not the processing for the image data performed abnormally has ended, a flag acquiring step for acquiring the flag stored by the flag storing step, and a flag acquired by the flag acquiring step From the abnormal termination determination step for determining whether the processing has been completed normally or abnormally at the end of the processing of the previous image data, and when starting, the determination result by the abnormal termination determination step is an abnormal termination. If it is determined, the parameter storage step A startup parameter changing step of changing the stored parameters, characterized in that it comprises.

  According to the present invention, it is possible to know at the time of startup whether the apparatus has abnormally ended the data processing performed based on the stored setting value last time, and if it ended abnormally last time, Change the set value. Thereby, the apparatus can be prevented from reading a set value that induces abnormal termination at the time of activation, and abnormal termination at the time of activation can be avoided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram for explaining the apparatus configuration of an image processing apparatus according to the first embodiment of the present invention.

  As shown in FIG. 1, the image processing apparatus includes a CPU 101. The CPU 101 controls the operation of the entire apparatus and executes a program stored in the primary storage device 102.

  The primary storage device 102 is mainly a memory, and reads and stores programs stored in the secondary storage device 103. The secondary storage device 103 is, for example, a hard disk or the like, and generally stores programs and data that are larger than the capacity of the primary storage device 102 and cannot be stored in the primary storage device 102. Data that must be stored for a long time is also stored in the secondary storage device 103.

  In the present embodiment, a program for realizing the processing procedure is stored in the secondary storage device 103, read into the primary storage device 102 when the program is executed, and executed by the CPU 101.

  The input device 104 is, for example, a mouse or a keyboard, and is used for sending an interrupt signal to a program or the like. The output device 105 is, for example, a monitor or a printer. The reading device 106 is a device that directly or indirectly reads an image captured by an imaging device with a digital camera or the like into the primary storage device 102 or the secondary storage device 103.

  FIG. 3 is a diagram illustrating an outline of a GUI of an application used in the image processing apparatus according to the present embodiment.

  In FIG. 3, the image display unit 301 displays an image to be processed. An image is specified by dragging and dropping a file from the file management system of the operating system to the image display unit 301.

  The parameter setting unit 302 sets the type of image processing and parameters. In the application according to the present embodiment, selection of a color conversion profile and whether to apply image processing A, image processing B, and image processing C can be set. The color conversion profile is selected from a pre-stored file using a pull-down menu.

  When the apply button 303 is pressed, the image is processed according to the parameters set by the parameter setting unit 302, and the processed image is displayed on the image display unit 301. When the end button 305 is pressed, the operation of the application is ended.

  In the present embodiment, a correspondence table (hereinafter, set value list) of parameter types and values used in an application is stored in the secondary storage device 103.

  The stored values are, for example, the position and size of the application window, an image displayed when the application is activated, and various image processing parameters.

  Each time an image file is dropped on the image display unit 301, the path of the image file is saved in the setting value list. Each time the parameter is changed by the parameter setting unit 302, the contents of the set value list are changed. FIG. 5 shows an example of the set value list.

  FIG. 4 is a flowchart for explaining an operation example of an application in the image processing apparatus according to the present embodiment. Here, each processing in FIG. 4 is executed by the CPU 101 by reading the processing program stored in the secondary storage device 103 into the primary storage device 102.

  First, in step S401, processing at the time of starting an application in the image processing apparatus is performed. Details of the processing at the time of activation will be described later with reference to FIG.

  In step S402, the illegal termination flag bCRASHED is set to TRUE and stored in the setting value list.

  In step S403, the user performs an operation through the GUI illustrated in FIG. 3, and the application performs a process according to the operation. Details of the application process will be described later with reference to FIG.

  In step S404, since the application process in step S403 has been completed normally, the illegal termination flag bCRASHED is set to FALSE and saved in the setting value list.

  FIG. 6 is a flowchart for explaining the application startup process in step S401 of FIG.

  First, in step S601, an illegal end flag bCRASHED is acquired from the set value list.

  In step S602, the value of bCRASHED is checked to determine whether the application ended normally last time. If bCRASHED = TRUE, the application determines that it ended abnormally last time, and proceeds to step S603. If bCRASHED = FALSE, the application determines that it ended normally last time, and proceeds to step S607.

  In step S603, a dialog box (FIG. 8) for notifying the user that the stored setting value is to be initialized is displayed on the image display unit 301. In step S604, in the dialog box shown in FIG. Performs the operation.

  In step S605, it is determined in step S604 whether or not the user has instructed initialization of values in the setting value list. If the OK button 801 in FIG. 8 is pressed, the process proceeds to step S606, and if the ignore button 802 in FIG. 8 is pressed, the process proceeds to step S607.

  In step S606, the setting value list values are initialized. In the present embodiment, the values of all items in the setting value list are initialized, but only specific items may be initialized.

  Next, in step S607, the value of the setting value list is acquired, and in step S608, the setting value acquired in step S607 is used and reflected in the application. Similarly, the image processing parameter acquired in the same manner is used to process the image and display it on the image display unit 301.

  In the image processing apparatus according to the present embodiment, an image is displayed on the image display unit 301 at the time of activation. Therefore, information necessary for image processing such as color conversion profile information is acquired at the time of activation. In the case of an image processing apparatus that does not display an image at startup, information necessary for image processing is acquired at startup in order to speed up the processing.

  FIG. 7 is a flowchart for explaining the application process in step S403 of FIG.

  First, in step S701, the user performs an operation via the GUI shown in FIG. 3, and in step S702, it is determined whether or not the end button 305 in FIG. 3 is pressed in step S701.

  If the end button 305 is pressed in step S305, the application process ends normally. If the end button 305 is not pressed, the process proceeds to step S703.

  In step S703, it is determined whether or not the setting value of the parameter setting unit 302 in FIG. 3 has been changed in step S701. If it is determined that it has been changed, the process proceeds to step S704, and if it is determined that it has not been changed, the process proceeds to step S705.

  In step S704, the changed parameter value is stored in the set value list. Then, it returns to step S701 and waits for user operation.

  In step S705, it is determined whether or not the apply button 303 has been pressed in step S701.

  If it is determined in step S705 that the apply button 303 has been pressed, the process proceeds to step S706. Otherwise, the process returns to step S701 to wait for a user operation.

  In step S706, image processing is started in the sub thread. In the sub thread, the processes in steps S707 to S709 are executed. Then, it returns to step S701 and waits for user operation.

  In step S707, the image processing parameters stored in the set value list are acquired. In step S708, the image is processed based on the image processing parameter acquired in step S707.

  For example, for a color conversion profile, a file with a path indicated by a parameter is opened, a color conversion matrix written in the file is acquired, and applied to an image. The procedure for applying the color conversion matrix to the image will be described later with reference to FIG.

  In this step, a memory error, a bus error, or the like may occur, and the application process may not be continued. A situation in which the application is forcibly terminated in such a state is called “abnormal termination”.

  In step S709, the processed image is displayed on the image display unit 301. Thereafter, the process is terminated, and the operation of the sub thread is stopped.

  Next, a procedure for applying the color conversion matrix M to an image having a size of W pixels × H pixels will be described with reference to FIG. Here, the color conversion matrix is a 3 × 3 matrix, which is multiplied by a color array C (r, g, b) composed of R, G, and B values of arbitrary pixels. It can be converted into the array C ′ (r ′, g ′, b ′). In the present embodiment, r, g, and b are all values between 0 and 255.

  If the color conversion matrix M is expressed by the following equation (1), the conversion from the color array C to C ′ is expressed by the following equation (2).

  The above equation (2) becomes the following equation (3), and r ′, g ′, and b ′ are calculated by the following equations (4) to (6), respectively.

  First, an area of W pixels × H pixels is secured in the primary storage device 102, and image data is copied. This area can be accessed as a two-dimensional array of pixels, and the i-th pixel in the horizontal direction and the j-th pixel in the vertical direction starting from the upper left are p (i, j). Also, the original color array of the pixel p (i, j) is C (i, j) {r (i, j), g (i, j), b (i, j)}, and the converted color array is Let C ′ (i, j) {r ′ (i, j), g ′ (i, j), b ′ (i, j)}.

  In FIG. 13, 1 is substituted for variable j in step S1301, and 1 is substituted for variable i in step S1302.

  In step S1303, using the color conversion matrix M, the color array C (i, j) {r (i, j), g (i, j), b (i, j)} of the pixel p (i, j)}. Is converted to C ′ (i, j) {r ′ (i, j), g ′ (i, j), b ′ (i, j)}. The conversion is performed by the method described above using the above formulas (1) to (6).

  In step S1304, it is determined whether r ′ (i, j) is a value between 0 and 255. If 0 ≦ r ′ (i, j) ≦ 255, the process proceeds to step S1306. If 0> r ′ (i, j) or r ′ (i, j)> 255, the process proceeds to step S1305.

  In step S1305, r '(i, j) is clipped from 0 to 255. When 0> r ′ (i, j), r ′ (i, j) = 0, and when r ′ (i, j)> 255, r ′ (i, j) = 255.

  In step S1306, it is determined whether g ′ (i, j) is a value between 0 and 255. If 0 ≦ g ′ (i, j) ≦ 255, the process proceeds to step S1308. If 0> g ′ (i, j) or g ′ (i, j)> 255, the process proceeds to step S1307.

  In step S1307, g ′ (i, j) is clipped from 0 to 255. When 0> g ′ (i, j), g ′ (i, j) = 0, and when g ′ (i, j)> 255, g ′ (i, j) = 255.

  In step S1308, it is determined whether b ′ (i, j) is a value between 0 and 255. If 0 ≦ b ′ (i, j) ≦ 255, the process advances to step S1310. If 0> b ′ (i, j) or b ′ (i, j)> 255, the process proceeds to step S1309.

  In step S1309, b ′ (i, j) is clipped from 0 to 255. When 0> b ′ (i, j), b ′ (i, j) = 0, and when b ′ (i, j)> 255, b ′ (i, j) = 255.

  In step S1310, the variable i is incremented by “1”, and i and W are compared in step S1311. If i> W in step S1311, the process proceeds to step S1312, and if not, the process proceeds to step S1303.

  In step S1312, the variable j is incremented by 1 and j and H are compared in step S1313. If j> H in step S1313, the process ends. If not, the process returns to step S1302. Thereafter, when applying the color conversion matrix, the above procedure is followed.

  As described above, in the present embodiment, it is possible to know at startup whether the application of the image processing apparatus has ended abnormally during the previous image processing, and if the application has ended abnormally last time, it is saved. The set value is updated to the initial value at the user's discretion.

  Thereby, it is possible to prevent the setting value that induces abnormal termination of the application of the image processing apparatus from being read when the application is activated, and to avoid abnormal termination of the application at the time of activation.

(Second Embodiment)
Next, an image processing apparatus according to the second embodiment of the present invention will be described. In the present embodiment, portions different from those in the first embodiment will be mainly described, and the drawings and reference numerals will be used for portions that overlap or correspond to the first embodiment.

  In the first embodiment, when the application ends abnormally, the values in the set value list are initialized at the next start, thereby avoiding the abnormal end of the application at start.

  However, it is not always necessary to initialize the values in the setting value list. For example, a combination of setting values that cause abnormal termination may be presented to the user at the time of activation, and the change may be prompted.

  In this embodiment, the abnormal termination condition list shown in FIG. 10 is created, and each time an application terminates abnormally, a combination of setting values that cause abnormal termination is added to the list.

  By comparing the abnormal termination condition list with the set value list, it is possible to know in advance whether the application terminates abnormally with the current settings.

  Also, if the accumulated information is sufficiently large, it becomes possible to specify a setting value that causes the application to terminate abnormally. Note that the abnormal termination condition list is stored in the primary storage device 102.

  With reference to FIG. 9, the procedure of the start-up process in step 401 of FIG. 4 in the present embodiment will be described. Here, the setting value list BK is a list in which values of the setting value list at the previous activation are stored, and is stored in the primary storage device 102.

  First, in step S901, the illegal end flag bCRASHED is acquired from the set value list.

  In step S902, the value of bCRASHED is checked to determine whether the application ended normally last time. If bCRASHED = TRUE, the application determines that it ended abnormally last time, and proceeds to step S903. If bCRASHED = FALSE, the application determines that it ended normally last time, and proceeds to step S904.

  In step S903, the difference between the set value list and the set value list BK is taken, and this difference is added to the abnormal termination condition list. As a result, the combination of the setting values that were changed when the previous abnormal termination was performed is stored in the abnormal termination condition list.

  In step S904, the set value list is compared with the abnormal termination condition list. If there is a combination of setting values registered in the abnormal termination condition list in the setting value list, the application may be abnormally terminated if those setting values are reflected in the application.

  In step S905, it is determined from the comparison result in step S904 whether a combination of values that induces abnormal termination of the application exists in the set value list. If there is a combination of setting values that induces abnormal termination, the process proceeds to step S906, and if there is no combination of setting values that induces abnormal termination, the process proceeds to step S909.

  In step S906, the dialog box shown in FIG. In FIG. 11, as an example, there is shown a case where abnormal termination may be induced by a combination of the color change profile and the set values of the image processing A and the image processing C.

  In step S907, the user performs an operation in the dialog box shown in FIG. The user changes the value of the setting item in which the value that induces abnormal termination is set, and when the change is completed, presses the OK button.

  In step S908, the setting value changed by the user in step S907 is stored in the setting value list. In step S909, the value of the setting value list is acquired. In step S910, the setting value acquired in step S607 is used and reflected in the application. Similarly, the image processing parameter acquired in the same manner is used to process the image and display it on the image display unit 301. In step S911, the value of the setting value list is copied to the setting value list BK.

(Third embodiment)
Next, an image processing apparatus according to a third embodiment of the present invention will be described. In the present embodiment, portions different from those in the first and second embodiments will be mainly described, and the drawings and symbols are used for portions that overlap or correspond to the first and second embodiments. .

  In this embodiment, in addition to the operation of the second embodiment, an image processing apparatus that issues a warning in real time when a value set by a user induces abnormal termination during application execution will be described. .

  With reference to FIG. 12, the application process in step 403 of FIG. 4 in the present embodiment will be described.

  First, in step S1201, the user performs an operation via the GUI shown in FIG. In step S1202, it is determined whether or not the end button 305 is pressed in step S1201.

  If the end button 305 is pressed in step S1202, the application process ends normally. Otherwise, the process proceeds to step S1203.

  In step S1203, it is determined whether or not the setting value of the parameter setting unit 302 has been changed in step S1201. If changed, the process proceeds to step S1204. If not changed, the process proceeds to step S1205.

  In step S1204, the changed parameter value is stored in the set value list. In step S1205, the set value list is compared with the abnormal termination condition list. If there is a combination of setting values registered in the abnormal termination condition list in the setting value list, if those setting values are reflected in the application, the application may end abnormally.

  In step S1206, it is determined from the comparison result in step S1205 whether a combination of values that induces abnormal termination of the application exists in the set value list.

  If there is a set value combination that induces abnormal termination in step S1206, the process proceeds to step S1207, and if there is no set value combination that induces abnormal termination, the process returns to step S1201 and waits for a user operation.

  In step S1207, the dialog box shown in FIG. In FIG. 11, as an example, there is shown a case where abnormal termination may be induced by a combination of the color change profile and the set values of the image processing A and the image processing C.

  In step S1208, the user performs an operation in the dialog box shown in FIG. The user changes the value of the setting item in which the value that induces abnormal termination is set, and when the change is completed, presses the OK button.

  In step S1209, the setting value changed by the user in step S1208 is stored in the setting value list.

  In steps S1210 to S1214, operations similar to those described in steps S705 to S709 in FIG. 7 are performed.
