Description

  The present invention relates to an optical correction data registration processing device, and a control method and program therefor, and more particularly, to an optical correction data registration processing device for registering optical correction data in an imaging device main body capable of mounting a plurality of interchangeable lenses, and a control method thereof And the program.

  In recent years, the image output from an imaging device such as a digital camera is required to have higher image quality, and image degradation caused by the optical characteristics of the imaging optical system of the imaging device (hereinafter referred to as "optical image degradation"). Is becoming a problem. For this reason, it has been proposed to provide the image pickup apparatus with correction means for electronically correcting the optical image deterioration.

  In order to correct optical image deterioration electronically accurately, it is necessary to store optical correction data for correcting the optical image deterioration based on the optical characteristics of the imaging optical system in the image pickup apparatus main body. In particular, in a lens-replaceable digital camera, optical characteristic data and optical correction data of a plurality of mountable interchangeable lenses are required. Further, even in the case of interchangeable lenses having the same imaging optical system, their optical characteristics differ depending on optical parameter values such as focal length, subject distance, and aperture value. Therefore, for accurate correction of optical image degradation, as many optical characteristic data as possible and optical correction data corresponding to the range are required.

  In Patent Document 1, in the optical correction data registration program operating on a computer, a list of interchangeable lenses is displayed by name, and in the list, the user selects a registration target interchangeable lens to which optical correction data should be registered in the imaging apparatus main body. Methods are disclosed.

  Patent Document 2 discloses a method of searching for a captured image captured by an imaging device in a computer and acquiring and registering lens information of an interchangeable lens mounted on the imaging device main body at the time of imaging. There is. This makes it possible to avoid the failure of erroneously registering an interchangeable lens that should not be registered.

Unexamined-Japanese-Patent No. 2010-068491 JP, 2014-230218, A

  However, new models are being released one after another as interchangeable lenses that can be attached to the imaging apparatus body, and new functions are also added. As a result, the types of optical image degradation that the correction means of the imaging apparatus main body needs to handle also increase.

  On the other hand, there are also a plurality of models of the imaging apparatus main body, and the correction capability of the optical image degradation installed in each is generally different. For example, due to limitations in memory capacity and processing speed for cost reduction, the types of optical image degradation that can be corrected may be reduced. Further, due to the compatibility of the mount, the combination of a compatible imaging device and an interchangeable lens, such as a lens that can not be mounted or a lens that can be mounted via an adapter, is also complicated.

  Furthermore, in recent years, processing for correcting an image with higher accuracy has become possible. For example, there is an image restoration process in which a correction process is performed based on an optical transfer function (OTF). Such high-accuracy correction processing such as image restoration processing is very complicated processing and requires various information, so the amount of correction data required is generally large, but recently such high correction data There are also models that perform accurate correction processing with the camera body.

  Under such circumstances, even if the interchangeable lenses are listed by name on the computer as described in Patent Document 1, the user determines which of the listed interchangeable lenses should be registered with the optical correction data of the imaging device. It is difficult to do.

  Further, in the method described in Patent Document 2, first, it is necessary to capture a captured image from the imaging device main body into a computer. Therefore, this method is effective when registering the interchangeable lens group owned by oneself at the same time with the newly bought imaging device main body. However, in order to register an interchangeable lens newly bought at a later date, there has been an inconvenience that it is necessary to mount the interchangeable lens on the imaging device main body and perform trial shooting.

  An object of the present invention is to provide an optical correction data registration device capable of simplifying user's work relating to optical correction data registration, and preventing registration of improper optical correction data due to human error in an imaging apparatus main body to be noticed And providing the control method and program.

An optical correction data registration device comprising: means and storage means for storing optical correction data used in the first correction process corresponding to each of the plurality of interchangeable lenses, wherein the optical correction data registration device comprises: Selection means for selecting an interchangeable lens owned by a user of the imaging device, display means for displaying a list of the interchangeable lenses selected by the selection means in a user-selectable manner, and user selection among the interchangeable lenses displayed in the list And D. registration means for registering the optical correction data of the interchangeable lens with the imaging device.

  According to the present invention, it is possible to simplify the user's work relating to optical correction data registration, and to prevent the registration of inappropriate optical correction data due to a human error in the imaging device main body to which attention is paid.

There is. The optical correction data of the newly sold interchangeable lens is sequentially replenished to the optical correction data file 109 via the recording medium 113 or the Internet.

  FIG. 2 is a block diagram showing a schematic configuration of the camera 100. As shown in FIG.

  In FIG. 2, solid arrows indicate the flow of image data, and broken arrows indicate the flow of control signals and control data. The configuration of the mounted lens 104 described in FIG. 2 is a configuration common to the interchangeable lenses mountable to the camera body 101.

  The mounted lens 104 has an imaging optical system 211. The imaging optical system 211 includes a plurality of lenses including a focus lens and / or a zoom lens, and a diaphragm. A mounting unit (not shown) of the camera body 101 can mount various types of interchangeable lenses. The mounted lens 104 also includes a lens control unit (not shown) that detects the position of the zoom lens, the focus lens, and the aperture and transmits the position to the camera body 101. The lens control unit also drives the zoom lens, the focus lens, and the aperture to the designated position in accordance with an instruction from the camera body 101.

  The camera body 101 includes an imaging unit 210, a data processing unit 220, a recording medium 230, a data interface 231, a user interface 233, and a system control unit 234.

  The imaging unit 210 includes an imaging element 212 that converts an object optical image formed by the imaging optical system 211 into an electrical image signal, and a shutter (not shown) that controls the exposure amount of the imaging element 212. The imaging element 212 is configured by a photoelectric conversion element such as a CCD image sensor or a CMOS image sensor. The image sensor 212 has, for each pixel of its light receiving surface, R, G, and B color filters in a Bayer arrangement as shown in FIG.

The system control unit 234 has a function of managing and processing the entire camera body 101 and the mounted lens 104. The system control unit 234 detects the positions of the zoom lens, the focus lens, and the diaphragm via the lens control unit of the mounted lens 104, and controls the zoom lens, the focus lens, and the diaphragm to desired positions.

  The system control unit 234 is connected to the computer 102 via the USB cable 103 connected to the data interface 231, and stores the optical correction data transmitted from the computer 102 in a non-volatile internal memory.

  The basic operation of the camera body 101 will be described. The system control unit 234 controls the exposure time and signal readout timing of the image sensor 212, and transfers the image signal read from the image sensor 212 to the AGC and A / D converter 221 of the data processor 220. In the AGC and A / D converter 221, the AGC amplifies and corrects the intensity of the transferred image signal, and the A / D converter converts the amplified and intensity corrected image signal into digital data. The system control unit 234 transfers the output image data of the AGC and A / D conversion unit 221 to the image data conversion unit 222. The image data conversion unit 222 converts the image data from the AGC and A / D conversion unit 221 into image data of a predetermined gradation.

  Whether the system control unit 234 transfers the output image data of the image data conversion unit 222 directly to the image processing unit 224 or to the image processing unit 224 via the image deterioration correction processing by the image deterioration correction processing unit 223 You can choose The system control unit 234 determines this transfer path depending on whether or not the camera body 101 is set to perform the image deterioration correction process, and the presence or absence of the optical correction data for the interchangeable lens used for photographing.

  The image deterioration correction processing unit 223 corrects the optical image deterioration of the output image data (photographing data) of the image data conversion unit 222 based on the optical correction data stored in the nonvolatile built-in memory of the system control unit 234. There are various methods for the image deterioration correction process, and in the present embodiment, the method is not limited to the image deterioration correction process itself.

<Optical correction data registration process>
The optical correction data registration process from the computer 102 to the camera body 101 will be described with reference to FIGS. 4 to 8. As described above, the control unit 105 of the computer 102 loads the registration program 108 to execute optical correction data registration processing on the computer 102.

  FIG. 4 is a flowchart showing the flow of optical correction data registration processing. FIG. 5 illustrates an example of a UI (User Interface) of the registration program 108 displayed on the display device 110 of the computer 102. FIG. 6 shows a data communication sequence between the camera body 101 and the registration program 108 executed on the computer 102 according to the present embodiment.

  In the camera body 101, there are a plurality of interchangeable lenses that can be mounted in addition to the mounted lens 104, which is an interchangeable lens currently mounted, and these multiple interchangeable lenses are hereinafter referred to as a registration target interchangeable lens. A process of registering the optical correction data of the mounting lens 104 and the registration target interchangeable lens in the computer 102 in the camera body 101 by the registration program 108 will be described.

  When started, the control unit 105 (the registration program 108 operating above) opens the optical correction registration window 501 illustrated in FIG. 5 according to the flowchart shown in FIG.

  When the registration program 108 is activated, first, communication with the camera body 101 is checked, and it is confirmed whether the computer 102 is connected to the camera body 101 via the USB cable 103 (step S401). If the camera body 101 is not connected (NO in step S401), the registration program 108 notifies the user to that effect, and ends this processing. On the other hand, if the camera body 101 is connected to the computer 102 as in this embodiment (YES in step S401), the process advances to step S402.

  In step S402, the registration program 108 checks if the optical correction data has been updated in a server (not shown) via the Internet. If the update such as addition of optical correction data of the newly sold interchangeable lens is a server, the updated optical correction data is downloaded via the Internet, and the information of the optical correction data file 109 is updated. Update to things.

  Next, communication with the camera body 101 is established, and the registration program 108 requests the camera body 101 for unique information as shown in the communication sequence of FIG. 6 described later (step S601). The unique information is, for example, model information of the camera body 101 (body model information). The camera body 101 having received the transmission request transmits the requested unique information to the computer 102 (registration program 108) (step S602). Thus, the control unit 105 determines whether communication between the computer 102 (registration program 108) and the camera body 101 is normal, and acquires model information of the camera body 101 (step S403). Optical correction data to be registered in the camera body 101 is determined based on the model information acquired here.

  Thereafter, when the registration program 108 requests lens information registered in the camera body 101 (step S603), the camera body 101 transmits lens information to the computer 102 (registration program 108) in response to the request (step S603). S604). Thereby, the control unit 105 acquires lens information from the camera body 101 (step S404). In the present embodiment, the lens information acquired here includes the name and lens ID of the mounted lens 104 of the camera body 101, and the name and lens ID of the interchangeable lens whose optical correction data is already registered in the camera body 101. It is a registered lens list. Hereinafter, all interchangeable lenses included in the registered lens list are referred to as "registered interchangeable lenses".

  At this time, the camera body 101 may transmit all of the optical correction data of the registered interchangeable lens to the computer 102 together with the name of the registered interchangeable lens and the lens ID.

  The optical correction data registered in the camera body 101 is recorded in a non-volatile internal memory of the system control unit 234. Since the amount of optical correction data is large, the number of registered interchangeable lenses is limited. The number of registered interchangeable lenses is set between several and several tens in accordance with the model of the camera body 101. The registration program 108 is configured so that the number of lenses that can be registered by the camera body 101 can be known from the registered lens list information acquired in step S404.

  Next, the registration program 108 requests the camera body 101 for registered lens preset list information (step S605). In response to the request, the camera body 101 transmits registered lens preset list information to the computer 102 (registration program 108) (step S606). Thereby, the control unit 105 acquires registered lens preset list information from the camera body 101 (step S405). Registered lens preset list information is optical correction data of all interchangeable lenses (preset lenses) that can be mounted on the camera body 101 already on sale at the time of release of the camera body 101, and is stored in advance in the program ROM area of the system control unit 234. It is registered. However, the registered lens preset list information in the ROM area can not be rewritten while the optical correction data recorded in the nonvolatile built-in memory of the system control unit 234 can be rewritten. On the other hand, in the server after the release of the camera body 101, the optical correction data may be updated with high accuracy, or a defect may be found in the optical correction data, so that the optical correction data may be updated to eliminate the defect. In such a case, the system control unit 234 registers the updated optical correction data in the nonvolatile internal memory. The optical correction data updated by this can be applied by the camera body 101.

  If the camera body 101 is a model such as a cost reduction model or a downsizing model, the program ROM area may not have enough capacity to mount all the registered lens preset list information. In this case, among the optical correction data of the interchangeable lens mountable to the camera body 101, only the commonly used optical correction data is registered lens preset list information in the program ROM area.

  Thereafter, when the registration program 108 requests the mounted lens information from the camera body 101 (step S607), the camera body 101 transmits the mounted lens information to the computer 102 (registration program 108) in response to the request (step S608). . Thus, the control unit 105 acquires attached lens information from the camera body 101 (step S406). The attached lens information acquired here is the information held in the memory (not shown) of the camera body 101, and is the history information of the five interchangeable lenses attached to the camera body 101 now or in the past. . In the present embodiment, the mounted lens information is history information of five interchangeable lenses, but the history information of the interchangeable lenses for a preset number of lenses is not limited to the form of the present embodiment.

  Also, as shown in step S 609, when attachment or detachment of the attached lens 104 occurs in the camera body 101 during connection with the computer 102, information on a new attached lens 104 is notified from the camera body 101 to the registration program 108 as an event. Ru. The registration program 108 updates the acquired attached lens information in response to the notification of this event. As a result, the registration program 108 can detect the information of the mounted lens 104 in the camera body 101 in real time, and can update the mounted lens information.

  Next, the registration program 108 confirms the downloaded interchangeable lens in step S407. Here, the downloaded interchangeable lens is an interchangeable lens on which correction data to be used in correction processing such as image restoration processing for a captured image transmitted from the camera body 101 to the computer 102 is already executed. Point to The correction processing such as the image restoration processing is to correct the defect of the image caused by the optical characteristic of the interchangeable lens used to obtain the photographed image by the camera 100. The processing is more accurate and complex than the image degradation correction processing performed in Therefore, since various information is required, the necessary correction data (hereinafter, referred to as “correction data for image restoration processing”) is generally larger than the data amount of the optical correction data used for the image deterioration correction processing. Therefore, the medium of the image editing software does not include the correction data for image restoration processing, and is acquired separately from an external server or the like via the Internet as necessary to be separated from the software main body. When developing the image restoration processing applied to the captured image (RAW image file) from the camera body 101, the user operates the UI shown in FIG. 8 to correct data for the interchangeable lens used for capturing the captured image. Need to be downloaded onto the computer 102.

  In the present embodiment, correction processing such as image restoration processing performed by the image editing software is performed on the computer 102, but the present invention is not limited to this. For example, it may be performed by the camera body 101. However, even in this case, in step S407, the downloaded interchangeable lens of the correction data to be used for the correction process is confirmed.

<Registration UI description>
In step S408, the registration program 108 displays an optical correction data registration UI shown in FIG. In the owned lens list 502 of FIG. 5, the interchangeable lenses owned by the user of the camera main body 101 are sorted out from the plurality of interchangeable lenses whose optical correction data is stored in the optical correction data file 109 by the processing of FIG. List. Next to each interchangeable lens displayed in the owned lens list 502, on-off user selectable check boxes are arranged.

  The registration program 108 checks the check box in front of the registered interchangeable lens name on the owned lens list when the registered interchangeable lens name acquired from the camera body 101 in step S404 is on the owned lens list. Put in Thereby, the user can visually confirm the registered interchangeable lens of the camera body 101 in the optical correction data registration UI of FIG.

  FIG. 7 is a flowchart showing the procedure of the owned lens list display control process in step S408 in FIG.

  First, in step S701, the registration program determines whether the first check box 503 in FIG. 5 is on or off. Here, the first check box 503 is checked by default with a check mark on. In the case of such default setting, as described in detail in step S 702, the registration program automatically adds the name of the interchangeable lens mounted on the camera body 101 to the owned lens list 502. In addition, the user can remove the check mark by selecting the first check box 503, and can turn off the first check box 503. That is, the user can select whether to perform such automatic addition.

  If the first check box 503 is on (YES in step S701), the registration program 108 proceeds to step S702. If the first check box 503 is off (NO in step S701), the registration program 108 proceeds to step S703.

  In step S702, the registration program confirms whether all of the interchangeable lenses included in the attached lens information of the camera body 101 acquired in step S406 are registered in the owned lens list information stored in the HDD 107. If there is an unregistered interchangeable lens, the interchangeable lens is added to the top of the owned lens list information, and if all are registered, the process proceeds to step S703.

  In step S703, the registration program determines whether the second check box 504 in FIG. 5 is on or off. Here, the second check box 504 is checked by default when checked. In such a case, as described in detail in step S704, the registration program automatically adds, to the owned lens list 502, the name of the downloaded interchangeable lens whose image restoration processing correction data has been downloaded (acquired). Note that the user can remove the check mark by selecting the second check box 504, and can turn off the second check box 504. That is, as in the first check box 503, it is possible for the user to select whether or not to perform such automatic addition.

  If the second check box 504 is on (YES in step S703), the registration program 108 proceeds to step S704. If the second check box 504 is off (NO in step S703), the registration program 108 proceeds to step S705.

  In step S704, the registration program 108 confirms whether all the downloaded interchangeable lenses confirmed in step S407 are registered in the owned lens list information stored in the HDD 107. If there is an unregistered interchangeable lens, the interchangeable lens is added to the top of the owned lens list information, and if all are registered, the process proceeds to step S705.

  In step S705, the registration program 108 puts a check mark as registered for the registered interchangeable lenses included in the lens information acquired in step S404 among the interchangeable lenses displayed in the owned lens list 502. If there are unregistered registered lens list information stored in the HDD 107 among the registered interchangeable lenses, the registration program 108 registers the interchangeable lens in the owned lens list information. The owned lens list 502 is updated based on the owned lens list information after the registration.

  In step S706, the registration program 108 performs an out-of-support lens correspondence process. Specifically, first, the model information of the camera body 101 acquired in step S403 and the information of the optical correction data file 109 updated in step S402 are referenced to determine whether or not there is a lens not to be supported. . Here, among the interchangeable lenses displayed on the owned lens list 502, the lens not to be supported is an interchangeable lens that can not be attached to the camera body 101 or an image degradation correction process performed by the image degradation correction processing unit 223. Point out interchangeable lenses that are not compatible. Next, if there is no lens not to be supported, the process proceeds directly to step S707. On the other hand, when there is such an unsupported lens among the interchangeable lenses displayed in the owned lens list 502, the user can not select the check box of the lens. At this time, as shown in the detailed information display column 508 displayed along with the name of the lens, a user message (detailed information) regarding the registration of optical correction data for that lens, such as "this camera can not be registered" is displayed. Then, it progresses to step S707.

  In step S 707, the registration program 108 confirms the registered lens preset list information acquired from the camera body 101 in step S 405, and determines whether the owned lens list 502 includes a preset lens.

  If the preset lens is not included in the owned lens list 502 (NO in step S 707), the process ends. On the other hand, if the preset lens is included in the owned lens list 502 (YES in step S 707), the process corresponding to the preset lens is performed in step S 708, and the present process ends. Here, specifically, in the preset lens correspondence processing, first, a check mark is put on the preset lens and display control is performed so that the user can not remove the check from the check mark. Next, as shown in the detailed information display column 509, a user message (detailed information) regarding the registration of the optical correction data to the preset lens, such as “no registration required” is displayed. By this display, the user can grasp that optical correction is possible with the camera body 101 without registration. Note that control may be performed so that the check box is not displayed for the preset lens of the owned lens list 502.

  However, there are cases where the version of the optical correction data for the preset lens in the owned lens list 502 is newer than that contained in the registered lens preset list information, and the version of the optical correction data file 109 is newer. In such a case, as shown in the detailed information display column 510, a user message (detailed information) regarding the registration of the optical correction data for the preset lens, such as "there is updated data" is displayed. In this case, it is necessary for the user to determine whether or not the new version of the optical correction data should be registered in the camera body 101 even for the preset lens. Therefore, a check mark is put on such a preset lens and display control is performed so that the user can uncheck the check mark.

  Returning to step S409, the registration program 108 edits the optical correction data to be registered in the camera body 101, based on the user's operation on the registered optical correction data registration UI of FIG. Specifically, when the check mark of the check box of the owned lens list 502 for which display control has been performed by the process shown in FIG. 7 is turned on by the user, the optical correction data of the interchangeable lens of the check box is to be registered. I assume. On the other hand, the optical correction data of the interchangeable lens of the check box turned off by the user is excluded from the registration target. Thereafter, when the user presses the OK button 506 in FIG. 5, the edit content is determined, and the registration program 108 proceeds to step S410.

  In step S410, the registration program 108 registers optical correction data with respect to the camera body 101. Specifically, in step S610, a registration request is transmitted to the camera body 101 together with the optical correction data of the interchangeable lens whose check box in the owned lens list 502 is on. When the camera body 101 completes updating of the optical correction data in the nonvolatile internal memory of the system control unit 234 in response to the registration request, the camera body 101 transmits an optical correction data registration completion notification to the registration program 108 (step S611). ). When the registration program 108 receives the notification, the registration program 108 determines that the optical correction data is normally registered in the camera body 101, and ends the present process. When the registration request transmitted in step S610 is performed for each interchangeable lens in which the check box of the owned lens list 502 is on, the processing in steps S610 to S611 is repeatedly performed for each of the interchangeable lenses.

  As described above, the display control shown in FIG. 5 is performed by turning on the first check box 503 and the second check box 504 without creating or maintaining a list of interchangeable lenses individually owned by the user. The owned lens list 502 is updated. Therefore, when the user selects an interchangeable lens from which the optical correction data is to be registered from the owned lens list 502, the risk of erroneous selection can be avoided.

  However, in an environment where a camera shared by a newspaper company or the like is used, the display content of the owned lens list 502 updated by turning on the first check box 503 or the second check box 504 is the content expected by the user. And may differ. In order to cope with such a case, a button 507 which can be pressed by the user with the first check box 503 and the second check box 504 turned off is provided. When the button 507 is pressed, a list showing the names of all the interchangeable lenses in the optical correction data file 109 for holding the optical correction data is displayed, and the interchangeable lenses manually selected from among them are optical It is set to the interchangeable lens which should register correction data.

  In addition, the preferable arrangement order of the interchangeable lenses displayed in the owned lens list 502 differs depending on the use situation of the user. Therefore, the arrangement order can be changed upward or downward by pressing one of the buttons 505 a and 505 b in a state where one of the interchangeable lenses displayed in the owned lens list 502 is selected by the user. It is like that. When the change of the arrangement order is performed, the arrangement order is stored so that the interchangeable lenses are displayed in the owned lens list 502 in the arrangement order after the change even when the registration program 108 is started next time.

  Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes can be made within the scope of the present invention.

  For example, although the registration program is operated on the computer 102 in the above embodiment, the registration program may be operated on a device other than the computer 102, for example, a portable information terminal device.
