In addition, the Example shown below does not limit the content of the invention described in the claim at all. In addition, all of the configurations shown in the following embodiments are not necessarily essential as means for solving the problems described in the claims.

  FIG. 1 is a functional block diagram of a projector 100 in the present embodiment.

  The projector 100 includes an input unit 110 that inputs user operation information, a storage unit 120 that stores various data, a timer unit 150, an image generation unit 160, and a projection unit 190.

  In addition, the storage unit 120 includes setting data 122 that indicates the setting of the projector 100 and whether or not the setting can be updated, a protection condition that indicates protection of the setting, a condition data 124 that indicates a cancellation condition that indicates the cancellation of the protection, an image data 126, I remember it.

  In addition, the projector 100 includes a setting update unit 130 that updates the setting of the setting data 122 when the setting to be updated can be updated based on the operation information and whether or not the setting data 122 can be updated, operation information, and condition data. 124, and an update availability update unit 140 that updates the availability of the setting data 122 when the operation content matches the protection condition or the release condition.

  Here, the setting data 122 and the condition data 124 will be described in more detail. FIG. 2 is a diagram illustrating an example of the setting data 122 in the present embodiment.

  The items of the setting data 122 correspond to, for example, type, ID, protection, mode, and the like. Here, the type 1 is data set by the manufacturer, 2 is data for an authorized user having a special update authority, and 3 is data for a general user having no special update authority. Show.

  Further, the protection indicates that 1 is a non-updatable protection state and 0 is an updatable release state. In practice, the setting contents include general setting items such as brightness and contrast in addition to the mode.

  As described above, the setting data 122 includes authority user setting data indicating the setting of the authority user projector, authority user update availability data indicating whether the setting for the authority user can be updated, and general user projector setting. General user setting data indicating general user update data and general user update availability data indicating whether the above settings can be updated.

  Next, the condition data 124 will be described. FIG. 3 is a diagram illustrating an example of the condition data 124 in the present embodiment.

  The items of the condition data 124 include, for example, a type, a protection condition for protecting the projector settings, a release condition for releasing the protection, and the like. Although the type 1 is a manufacturer setting, the manufacturer setting cannot be updated at all times and is not included in the condition data 124.

  Therefore, in the setting data 122, the protection condition data for the authority user indicating the protection condition for the authority user, the release condition data for the authority user indicating the release condition for the authority user, and the protection for the general user indicating the protection condition for the general user. Condition data and general user release condition data indicating release conditions for general users are included. These conditions are all different.

  For example, the protection condition for the authorized user is that the upper key of the remote control (remote controller) is pressed for 3 seconds or more and then the menu key of the remote control is pressed 4 times within 5 seconds. The release condition for the authorized user is Press the down key for 3 seconds or more and then press the remote control menu key 4 times within 5 seconds. The general user protection condition is to press the remote control left key for 3 seconds or more and then press the remote control menu key for 5 seconds or less. The release condition for general users is to press the right key of the remote control for 3 seconds or more and then press the menu key of the remote control once within 5 seconds.

  The format of each condition is “key name, number of continuous pressing seconds, time limit in seconds, number of times of pressing within time limit”. In each condition column, the conditions are specified by combining a plurality of key operations by repeatedly setting them.

  Note that the functions of each unit such as the setting update unit 130 can be implemented in the projector 100 using the following hardware, for example. FIG. 4 is a hardware block diagram of the projector 100 in the present embodiment.

  For example, the input unit 110 is an infrared receiving unit 940 that receives infrared light from a remote controller, the storage unit 120 is a RAM 950, a ROM 960, etc., the setting update unit 130, the update availability update unit 140 is a CPU 910, etc. 150 may be a system timer 930, the image generation unit 160 may be an image processing circuit 970, and the projection unit 190 may be a liquid crystal panel 920, a lamp, a lens, or the like. Note that these units can exchange information with each other via the system bus 980.

  Further, the projector 100 may implement functions such as the setting update unit 130 using a program. For example, the projector 100 may read the program for causing the computer of the projector 100 to function as the setting update unit 130 or the like from the information storage medium 900 and implement the function of the setting update unit 130 or the like.

  As such an information storage medium 900, for example, a CD-ROM, a DVD-ROM, a ROM, a RAM, an HDD, or the like can be applied, and the program reading method may be a contact method or a non-contact method. Good.

  Next, a flow of processing related to setting using the setting update unit 130 and the like will be described. FIG. 5 is a flowchart showing a flow of processing relating to setting in the present embodiment.

  Here, a case where a manufacturer person in charge (authorized user) goes to a general user's home to set the projector 100 will be described as an example. The person in charge operates the remote controller and instructs the projector 100 to set the environment. Input unit 110 inputs operation information from a remote controller.

  The image generation unit 160 generates a setting image based on the setting data 122 and the image data 126 according to the operation information from the input unit 110, and the projection unit 190 projects the setting image (step S1).

  FIG. 6 is a diagram illustrating an example of the setting image 300 in the present embodiment. The image generation unit 160 generates a setting image 300 indicating records for each ID in the order of the setting data 122 ID. Further, the image generation unit 160 indicates a key mark for a record in which “protection” in the setting data 122 is “1”, and does not indicate a key mark for a record in which “protection” is “0”. As described above, the setting image 300 is generated. That is, a record in which the key mark in the setting image 300 is displayed indicates that the record cannot be updated, and a record in which the key mark is not displayed can be updated.

  Further, the image generation unit 160 displays an image indicating the type such as “maker setting 1”, “special setting 1”, “user setting 1”, “presentation”, “theater” according to “ID” of the setting data 122. A setting image 300 indicating a part of the setting for each record is generated.

  In addition, the image generation unit 160 places the cursor 310 on the portion of the record having the smallest “ID” among the records whose “protection” is “0” in the setting image 300.

  It should be noted that the movement range of the cursor 310 is only the portion of the record in which “protection” is “0” in the setting image 300, that is, the record in which “protection” is “1”, that is, the key Does not move to a record with a mark.

  The update availability update unit 140 determines whether or not there is a cancellation instruction by determining whether or not operation information indicating a cancellation instruction is input from the input unit 110 (step S2). Here, it is assumed that the person in charge gives a release instruction by pressing the lower key of the remote control for 3 seconds or more and then pressing the menu key of the remote control 4 times within 5 seconds.

  The update availability update unit 140 identifies that the lower key of the remote controller has been pressed based on the operation information from the input unit 110, and based on the operation information continuously input and the timer value of the timer unit 150. Identifies that the down key was pressed for 3 seconds or more.

  Furthermore, the update availability update unit 140 identifies that the menu key of the remote controller has been pressed four times within 5 seconds based on the operation information from the input unit 110 and the timer value of the timer unit 150. Then, the update availability update unit 140 determines whether there is a release instruction by determining whether the identified operation content matches any of the conditions in the condition data 124.

  When there is a release instruction, the update enable / disable update unit 140 releases the protection of the corresponding record by updating “protection” of the setting data 122 matching the “type” of the matched release condition to “0” ( Step S3). In this case, “Protection” of “201” and “202” of the setting data 122 is updated from “1” to “0”.

  The image generation unit 160 generates a setting image based on the setting data 122 whose protection is canceled, and the projection unit 190 projects the setting image. FIG. 7 is a diagram illustrating an example of the setting image 302 at the time of cancellation of protection in the present embodiment.

  For example, when the person in charge cancels the protection of the record of the special settings 1 and 2, the key mark of the record part is removed, and the setting image 302 in which the cursor 310 is arranged on the record part of the special setting 1 is projected. Is done.

  The person in charge performs an operation of moving the cursor 310 to a desired record portion using the remote controller, and the image generation unit 160 moves the cursor 310 based on the operation information from the input unit 110 (step S4).

  For example, when the person in charge moves the cursor 310 to the record part of the special setting 2 and presses the Select key on the remote controller, a setting image for setting the mode, brightness, etc. is projected, and the person in charge sets the desired setting. Do.

  The setting update unit 130 updates the setting of the setting data 122 based on the operation information from the input unit 110 (step S5). Further, the update availability update unit 140 determines whether there is an instruction to protect the record based on the operation information from the input unit 110 and the timer value of the timer unit 150 (step S6).

  For example, the person in charge performs an operation for protecting the record as necessary when completing the setting. Here, it is assumed that the person in charge gives the protection instruction by pressing the upper key of the remote control for 3 seconds or more and then pressing the menu key of the remote control 4 times within 5 seconds.

  Based on the operation information from the input unit 110, the update availability update unit 140 identifies that the upper key of the remote controller has been pressed, and based on the operation information continuously input and the timer value of the timer unit 150. Identify that the up key was pressed for more than 3 seconds.

  Furthermore, the update availability update unit 140 identifies that the menu key of the remote controller has been pressed four times within 5 seconds based on the operation information from the input unit 110 and the timer value of the timer unit 150. Then, the update availability update unit 140 determines whether or not there is a protection instruction by determining whether or not the identified operation content matches any condition in the condition data 124.

  When there is a protection instruction, the update enable / disable update unit 140 protects the corresponding record by updating the “protection” of the setting data 122 that matches the “type” of the matched release condition to “1” (step S100). S7). In this case, “Protection” of “201” and “202” of the setting data 122 is updated from “0” to “1”.

  Then, the projector 100 determines whether or not the setting is completed by determining whether or not the operation information indicating the completion of the setting (pressing the ESC key of the remote controller in this embodiment) is input to the input unit 110 (step S8). .

  The projector 100 ends the above-described process when the setting is completed, and repeatedly executes the above-described process when the setting is not completed.

  As described above, according to the present embodiment, the projector 100 sets the protection condition for the authorized user, the release condition, the protection condition for the general user, and the release condition, and sets the compatibility of the operation information and these conditions. By determining, protection and release of the setting data 122 can be set. Therefore, the projector 100 can more appropriately protect and cancel the setting data 122 according to the role of the user.

  Further, according to the present embodiment, the projector 100 sets the manufacturer data in the setting data 122 so that the data set by the manufacturer is always non-updatable, thereby eliminating the risk that the data provided by the manufacturer is erroneously overwritten. it can.

  Further, according to the present embodiment, the projector 100 makes the setting data for the authority user erroneously by changing the protection condition, the release condition, the protection condition for the general user, and the release condition for the authority user, respectively. Therefore, the setting data can be protected and released more appropriately according to the role of the user.

  Further, according to the present embodiment, the projector 100 projects the setting images 300 and 302 indicating whether update is possible or not, thereby reducing the risk that the user erroneously updates the setting data 122.

  Further, according to the present embodiment, the projector 100 projects the setting images 300 and 302 indicating the settings, thereby reducing the risk that the user will accidentally update the setting data 122 and the user. Can update the setting data 122 with reference to the setting.

  In addition, according to the present embodiment, the projector 100 determines whether the setting data 122 matches the condition by combining a plurality of key operations or including the time required to input the operation information. Can reduce the risk of being updated, and more appropriately protect and cancel the setting data 122.

  Further, according to this embodiment, the projector 100 can protect and cancel the setting data 122 for each record.

  Further, according to the present embodiment, the projector 100 can reduce the risk that the setting data 122 is erroneously updated by disabling selection of the protected record.

  Further, according to the present embodiment, the projector 100 can collectively change the protection or release of a plurality of records. In particular, even when the protected record is made unselectable, the projector 100 can release the protection in a lump and update the setting by making the record selectable.

  Therefore, the projector 100 can appropriately protect the setting data 122 and improve the usability for the user. In particular, according to the present embodiment, since the setting data 122 of a plurality of users can be appropriately protected by the projector 100 alone without using a PC or USB memory, usability for the user can be improved.

  In addition, application of this invention is not limited to the Example mentioned above, A various deformation | transformation is possible.

  For example, in the embodiment described above, the projector 100 disables selection of protected records and protects or releases data in a lump. However, the protected record can be selected and protected or released one record at a time. May be.

  FIG. 8 is a diagram illustrating an example of the setting image 304 in another embodiment. FIG. 9 is a diagram illustrating an example of the setting image 306 at the time of cancellation of protection in other embodiments. For example, the record protection state is as shown in the setting image 304, and the person in charge moves the cursor 310 to the user setting 1 record when updating the protected user setting 1.

  In this state, the person in charge presses the right key of the remote control for 3 seconds or more and then presses the menu key once within 5 seconds to release the protection of the user setting 1 record and update the setting of the user setting 1. be able to.

  In addition, the projector 100 selects the update target using the cursor 310 in the setting image 300 or the like, but displays the ID or number of each record and selects the update target by inputting the ID or number from the remote control. You may let them.

  In the embodiment described above, the person in charge of the manufacturer performs the setting operation for the authorized user or the setting operation for the general user. However, the general user may perform the setting operation for the general user. Note that it is preferable that the protection conditions and release conditions for authorized users are not disclosed to general users.

  Further, although the setting images 300 and 302 described above are protected by displaying the key mark and cannot be selected, the display method is not limited to the key mark. For example, the image generation unit 160 may change the color of the record portion that is protected and cannot be selected to the color of the record portion that is not protected. For example, the image generation unit 160 may change the color of the unprotected record portion to light gray and the protected non-selectable record portion to gray.

  When the setting operation is performed in the above-described setting images 304 and 306 in a protected state, the image generation unit 160 generates a warning image indicating that the setting cannot be performed, and the projection unit 190 A warning image may be projected.

  Further, the operation content of the condition indicated in the condition data 124 is not limited to the above-described embodiment. For example, the protection condition and the release condition may be a condition indicating a single key operation, or may be a condition not using the timer value of the timer unit 150.
