Description

  The present invention relates to a portable information terminal and a portable information system, and more particularly to a portable information terminal and a portable information system that display an image of an object such as an animal or a plant and information related to the object.

2. Description of the Related Art In recent years, a portable information terminal is generally provided with an imaging unit so that an object captured by the imaging unit can be displayed on a display screen.
By the way, when the target object imaged with the portable information terminal is an animal or a plant, for example, there are cases where it is desired to know information related to the target object such as its general name and features. In such a case, it is necessary to use an information acquisition unit different from the portable information terminal such as a paper medium such as a picture book or an electronic medium such as the Internet together with an image captured by the portable information terminal. However, using an information acquisition unit different from the portable information terminal is inconvenient because the operation is complicated.

However, conventionally, as a portable information terminal that can eliminate the complexity of such operations, related information such as the general name of the imaged object is acquired using information acquisition means such as a database, and the display screen together with the object For example, the following Patent Document 1 proposes an apparatus that displays the above.

  An apparatus described in Patent Document 1 includes position information acquisition means for detecting a current position, direction information acquisition means for detecting a direction in which an object exists, position information regarding a plurality of objects, and related to the object Control for specifying a target object by searching a target object database based on a database storing information to be performed (for example, name), a current position detected by the position information acquiring unit, and a direction detected by the azimuth information acquiring unit And a display means for displaying information on the object specified by the control means. When the user points the device in the direction of the object, the position information acquisition unit specifies the current position, the direction information acquisition unit detects the direction, and the control unit detects the current position and direction. The object database is identified based on the object database. Next, the display means displays information regarding the identified object.

By the way, for example, there are cases where the ecology of a plurality of types of objects that freely move in a vast area is observed, such as observing a plurality of types of animals released in a safari park.
In such a case, the position of the object in the observation field is likely to vary within the observation field. For this reason, when observing a desired object in the observation field of view, once the eyes are removed from the object, the object may be lost even if the same observation field is observed thereafter.

Captured image is displayed on the display screen 2 ₁ (Step S1). Then, extraction means 3 ₁ extracts an object from an image displayed on the display screen 2 ₁ (step S2).
Then, the object position detection means 6, the display screen 2 ₁ captured image is displayed, extracting means 3 ₁ detects the position of the object extracted through (step S3). Then, the control unit 4 checks whether meet specific conditions which the position of the detected object is above the display screen 2 in ₁ to the displayed image (e.g., any of the conditions 1 to 3) (Steps S4 and S6). Position of the detected object, when certain conditions within displayed on the display screen 2 ₁ image, comparing means 3 _2, key information extracting means 3 ₁ object extracted via As shown in FIG. 4, collation processing is performed with data in a predetermined database (not shown) (steps S7 and S8). When there is data that matches the data in the database, information related to the object is acquired. Then, the display screen 2 ₁ displays the acquired information together with the image (step S9). The processing from the position check of the object to the display of the information related to the object is performed for all the extracted data (step S5).
Further, it is assumed that the observer presses a save instruction button (not shown). Then, storage means 5 stores and store image displayed on the display screen 2 ₁ in real time.

Therefore, according to the portable information terminal of the present invention, it is not necessary to display unnecessary information other than information related to the desired object on the display means 2 as much as possible. It can be made easier to see. Moreover, the display of information related to the desired object, the position of the desired object, since the limited when a specific condition is satisfied in displayed on the display screen 2 ₁ image, for example, the desired object There can be seen the information related to the desired object with pristine observation operation that to appear in the center of the display screen 2 _1.

  In addition, if the specific range that is a specific condition in the image of the position of the desired object is variable, information can be displayed under optimal observation conditions according to the size of the object, the distance to the object, and the like. And increase the degree of freedom of observation.

In the portable information terminal of the present invention, within which is displayed on the display screen 2 ₁ image, has a object designation means (not shown) that specifies the object to be detected by the object position detection means 3 Is preferred.
In this way, even when a plurality of objects are located in a position that satisfies the specific condition in the image, related information only on the desired object can be displayed.
For this reason, the subject and the captured image can be captured without moving the eyes and face so much that the operability is improved, and only the desired target is observed in the observation field of view without being concerned about the related information of other targets. The object can be tracked without losing sight while obtaining the related information, and it becomes easy to observe.

Further, in the portable information terminal of the present invention, in the image displayed on the display means, an object capable of displaying information is detected via the object related information acquisition means, and the detected object is detected.

It is preferable that relevant information is acquired and the acquired information is displayed on the display means.
By doing so, it is possible to obtain information related to only a desired object necessary for observation by eliminating information that obstructs observation in the observation screen as much as possible, and it is easy to see the observation screen.

In addition, it is preferable that the acquired information is simple information. Further, the acquired information may be detailed information.
Further, the display screen 2 ₂ to display detailed information, may be another screen and the display screen 2 ₁ to display the captured image. By doing so, the display contents of each other are not mixed, and the information on each display screen is easy to see. If a separate display screen is provided, for example, by configuring the portable information terminal so that the display screens overlap each other, each display content can be displayed largely on each display screen. As a result, the screen becomes easier to see, and the observation field of view and information to be obtained increase. The effect is particularly great when observing a plurality of types of animals that live in a free range in a large area such as a safari park.

By the way, when the object to be observed is an animal that emits sound, it is more preferable to hear the cry of the animal. However, the animal does not necessarily sound, and there may be a case where plural kinds of animals are mixed and it is impossible to specify which call is which animal. In addition, when observing from a distance, it may happen that the animal's voice with a small cry cannot be heard by the observer.

In this way, it is possible to avoid selecting an object without detailed information wastefully. In addition, when there are a plurality of objects, selection becomes easy, and errors in selection and recognition are eliminated. Furthermore, it becomes easy to notice an object that is difficult to notice in the observation field of view.
And you can capture images in a natural state while looking at a wide range as you see directly, and even if there are multiple objects in it, you can intuitively select the object you want to know detailed information about Can do.

  The information indicating that the detailed information can be acquired is acquired through a predetermined sign (a mark obtained by designing the object, a blinking display object, etc.) or the object related information acquisition means 3. Any object may be used as long as it can indicate that the object can obtain detailed information such as simple information such as the name of the object.

In the portable information terminal of the present invention, the display screen 2 a _second surface detailed information is displayed, is a touch panel, more preferable to be able to perform a predetermined screen operation through the touch panel.
The predetermined screen operation is preferably an operation for changing the display magnification of the detailed information.
