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

  FIG. 1 is a functional block diagram of the projector 10 in this embodiment. A projector 10 that is a type of electronic device includes a display device 100. In addition, the display device 100 includes an input unit 110 that inputs imaging data 132 from the memory card 20, an operation unit 120, a storage unit 130 that stores imaging data 132, display condition data 134, target data 136, and the like, and target data. The determination unit 140, the display unit 150, the processing unit 160, and the updating unit 170 are included.

  Note that a plurality of imaging data 132 and target data 136 are actually provided for each image. In addition, the memory card 20 can be incorporated in an imaging device such as a digital camera or a digital video camera, for example, and the imaging data 132 is stored when the imaging device incorporating the memory card 20 captures an imaging target.

  The target data determination unit 140 has a function of determining the target data 136 from the imaging data 132 based on the display condition data 134 and the processing result of the processing unit 160. The processing unit 160 performs edge processing according to the display conditions. It has a function of executing detection processing, sharpness detection processing, brightness detection processing, shutter speed detection processing, and the like. Here, the target data 136 is, for example, image data that conforms to display conditions and is suitable for continuous display.

  These units may be mounted on the projector 10 using the following hardware, for example. For example, the input unit 110 is a card interface, the operation unit 120 is a button, a touch panel, the storage unit 130 is a RAM, an HDD, the target data determination unit 140, the processing unit 160, and the update unit 170 is a CPU. As the unit 150, an image processing circuit, a liquid crystal driving circuit, a liquid crystal panel, a lamp, or the like may be employed.

  In addition, the display device 100 may implement functions such as the target data determination unit 140 by reading a program from the information storage medium 30. As such an information storage medium 30, for example, a CD-ROM, DVD-ROM, ROM, RAM, HDD or the like can be applied, and the reading method of the program can be a contact method or a non-contact method. Good.

  Next, processing procedures using these units will be described. FIG. 2 is a flowchart showing a processing procedure in the present embodiment.

  The update unit 170 determines a target imaging mode based on operation information by the user from the operation unit 120 and updates the display condition data 134. For example, when the user selects the night view mode as the display target in a state where the selected image of the imaging mode to be displayed is projected, the update unit 170 displays the display condition data 134 so that the display conditions are suitable for the night view mode. Update (step S1).

  For example, the display condition in the night view mode corresponds to a condition that the brightness value is equal to or higher than the first reference value and the shutter speed value is smaller than the second reference value. For example, as a display condition in the landscape mode, the condition that the brightness value is equal to or higher than the first reference value and the sharpness value is smaller than the third reference value, or the shutter speed value is the second reference value. This is the case and the condition that the sharpness value is smaller than the third reference value.

  The display conditions may include not only display conditions specific to the imaging mode but also common display conditions that are not related to the imaging mode. For example, the display condition includes a condition that the ratio of the number of pixels determined as an edge by the edge detection process is a predetermined value or more, a condition that pixels determined as an edge by the edge detection process are continuous for a predetermined value or more, and a sharpness value. There may be a condition that the value is a predetermined value or more, a condition that the brightness value is a predetermined value or more, a condition that the shutter speed value is a predetermined value or more, and the like.

  Further, for example, when the memory card 20 is connected to the projector 10 or when there is a data reading instruction operation using the operation unit 120 by the user, the input unit 110 inputs the imaging data 132 from the memory card 20. Is stored in the storage unit 130 (step S2). Note that the imaging data 132 may include, for example, a plurality of imaging data captured by the continuous imaging function of the digital camera, a plurality of imaging data captured by the user for continuous display, and the like.

  When new imaging data 132 is stored in the storage unit 130 or when a user performs a slide show-type image display instruction operation using the operation unit 120, the display device 100 executes the following processing. .

  First, based on the display condition data 134, the processing unit 160 performs a detection process corresponding to the display condition on the imaging data 132 (step S3). Here, it is assumed that display conditions specific to the night view mode are set in the display condition data 134. In this case, the processing unit 160 detects the brightness value and the shutter speed value of the captured image based on the captured data 132. Note that the processing unit 160 may obtain an average value of brightness values of all pixels as the brightness value, and obtain the shutter speed value in EXIF (Exchangeable Image File format) information included in the imaging data 132. The shutter speed value may be adopted.

  The target data determination unit 140 determines whether the detection processing result of the processing unit 160 satisfies the display condition based on the display condition data 134 (step S4). Here, the target data determination unit 140 determines whether or not the condition that the brightness value is equal to or larger than the first reference value and the shutter speed value is smaller than the second reference value is satisfied.

  When the display condition is satisfied, the target data determination unit 140 adds the detected imaging data 132 to the target data 136 (step S5). On the other hand, when the display condition is not satisfied, the target data determination unit 140 does not add the imaging data 132 to the target data 136. In addition, as a method of adding the imaging data 132 to the target data 136, a method of copying the imaging data 132 as it is including the EXIF information, a method of adding only a link to the imaging data 132, and the like are applicable. Here, the former method is adopted.

  The processing unit 160 determines whether or not the processing for all the data of the imaging data 132 has been completed (step S6). If the processing has not been completed, the processing unit 160 and the target data determination unit 140 target the next imaging data 132. As described above, the processes in steps S3 to S6 are repeatedly executed.

  The target data 136 is generated in the storage unit 130 by the above procedure. The target data determination unit 140 determines the display order for each imaging data based on the file name of each imaging data included in the target data 136, and updates the target data 136 by adding data indicating the display order to each imaging data. (Step S7). For example, when the file names are “DSCF0002”, “DSCF0009”, “DSCF0003”, “DSCF0004”, “DSCF0005”, “DSCF0007”, the display order is 1, 6, 2, 3, 4, 5.

  Based on the target data 136, the display unit 150 displays images continuously (for example, at intervals of 0.2 seconds, intervals of 0.5 seconds, etc.) according to the display order indicated by the target data 136 (step S8). Specifically, the display unit 150 of the projector 10 drives the liquid crystal panel based on the imaging data included in the target data 136 to form an image on the liquid crystal panel, and modulates light from the lamp with the liquid crystal panel. Project an image.

  As described above, according to the present embodiment, the projector 10 (display device 100) performs edge detection processing or the like on the imaging data 132, and whether or not the display condition is satisfied based on the processing result of the detection processing. Therefore, the target data 136 suitable for continuous display can be determined by excluding the imaging data 132 that is not suitable for continuous display without causing the user to perform a selection operation of the display target. By continuously displaying the images based on the above, it is possible to automatically and continuously display a plurality of images suitable for continuous display.

  Further, according to the present embodiment, the projector 10 satisfies the display condition at the time of imaging when, for example, the user adjusts the brightness or the like of the imaging data in the memory card 20 using a digital camera or a PC after imaging. In addition, since the imaging data 132 that satisfies the display condition by the adjustment can also be determined as the target data 136, an image can be displayed more generally.

  Further, according to the present embodiment, the projector 10 can automatically and continuously display only the imaging data that conforms to the display condition according to the user setting by causing the user to set the display condition. Thereby, the projector 10 can improve a user's usability (ease of use).

  Further, the projector 10 can automatically and continuously display an image that is in focus or an image with less blur by adopting a condition that the image is in focus or a condition that there is little blur as display conditions. . As a result, the projector 10 can display only images that look good in a slide show format.

  Further, according to the present embodiment, the projector 10 can automatically and continuously display images captured in an imaging mode (for example, night view mode, landscape mode, macro mode, etc.) designated by the user. .

  In addition, according to the present embodiment, the projector 10 automatically and continuously displays a plurality of images in an appropriate order by continuously displaying each image according to the display order corresponding to the imaging order. be able to.

  In addition, application of this invention is not limited to the Example mentioned above, A various deformation | transformation is possible. For example, when each imaging data 132 includes imaging mode data indicating the imaging mode, the processing unit 160, based on the imaging mode data, the imaging data 132 having the same imaging mode or imaging data corresponding to the designated imaging mode. The detection process may be executed for only 132. Note that the imaging mode data is included in, for example, EXIF information.

  Further, the time interval for displaying each image is not limited to the above-described embodiment. For example, the display interval of each image based on the target data 136 may be arbitrarily determined by the user. For example, in the case of the above-described embodiment, the target data determination unit 140 determines the display interval setting value by the user based on the operation information from the operation unit 120 and sets the display interval of the target data 136 at the display interval. May be.

  The processing unit 160 may be configured to execute all of the edge detection processing, sharpness detection processing, brightness detection processing, and shutter speed detection processing according to the corresponding display condition (specification). You may be comprised so that a detection process can be performed, and you may be comprised so that a several detection process can be performed.

  Further, the operation unit 120 and the update unit 170 are not essential components. For example, when the display conditions are fixed, these configurations are unnecessary. Further, the imaging order data indicating the imaging order is not limited to the file name, and may be, for example, an imaging date and time. In this case, for example, the target data determination unit 140 may determine the display order so that the older the imaging date and time, the earlier the display.

  In addition, the electronic device on which the display device 100 can be mounted is not limited to the projector 10, and may be a photo viewer, a PC, a mobile phone, a television, a digital camera, a digital video camera, a printer, or the like. Further, the function of the display device 100 may be distributed and implemented in a plurality of devices (for example, a PC and a projector).

  The projector 10 may be a front projection type or a rear projection type, and the liquid crystal panel may be a transmission type or a reflection type. Further, the projector 10 is not limited to a liquid crystal projector, and may be a projector using a DMD (Digital Micromirror Device), for example.
