It may be determined whether or not the observation object exists in the real field of view by determining whether or not the observation object registered in advance exists within a predetermined range.

According to the above configuration, the position and direction of the real field of view are specified by the azimuth information measurement unit, and within a predetermined range determined based on the specified position and direction, for example, the position specified by the azimuth information measurement unit As the center, the determination unit determines whether or not the observation object registered in advance is within the fan-shaped range drawn in the direction specified by the azimuth information measurement unit.

There is an effect that can be done.

An embodiment of an information terminal device according to the present invention will be described below with reference to the drawings.
1 and 2 are external perspective views showing a configuration example of an information terminal device according to an embodiment of the present invention. FIG. 1 is an external perspective view in a use state, and FIG. 2 is an external perspective view in a storage state. Show.
As shown in FIGS. 1 and 2, the information terminal device 1 according to the present embodiment includes a display device 30 and an imaging device (outside of a casing (main body) 20 including various control mechanisms and a control board described later. An imaging unit) 40 is provided.
The display device 30 includes an image display unit 50 and a combiner 60. The image display unit 50 and the combiner 60 are housed in a space part of the opening 21 that penetrates the housing 20 (see FIG. 2) in a retracted state, and each side of the short side that is rectangular is housing 20. Opening and closing operation by swinging is enabled.

  The image display unit 50 includes, for example, a so-called thin display (hereinafter referred to as “display surface”) 51 such as a liquid crystal display panel (LCD) or an organic EL display panel, and an image display control unit 75 (see FIG. 4) described later. The selected image is displayed on the display surface 51. The image display unit 50 is fixed to, for example, a support member 52 that is pivotally supported by the housing 20, and the display surface 51 is a surface that faces the combiner 60 described later in a stored state, in other words, the housing 20 is directed to the inside.

The combiner 60 reflects the light from the image display unit 50, that is, the light of information displayed on the display surface 51 of the image display unit 50, and transmits the light from the real field of view of the facility user. In other words, the combiner 60 has a free-form surface (three-dimensional aspheric surface) on at least one surface, transmits an external field image that is a real field of view, and displays information (for example, for example, on the display surface 51 of the image display unit 50). This is a transflective optical element that superimposes and displays an image or character as a virtual image on a real image in a real field of view.
In the present embodiment, the combiner 60 is a substantially rectangular plate-like member made of a transparent material such as acrylic or polycarbonate, and a reflective layer such as a metal film is formed on one side thereof. The surface of the reflective layer becomes a reflective surface 61 that reflects the light incident from the image display unit 50 on the surface.
In addition to the above-described transflective optical element, for example, a half mirror, a hologram element, or the like can also be adopted as the combiner 60, and one of these is appropriately selected and used according to the purpose. It is possible.

As shown in FIG. 2, the combiner 60 is disposed so that the display surface 51 of the image display unit 50 and the concave curved reflection surface 61 face each other in the retracted state.
In the state of use, as shown in FIG. 1, the reflective surface 61 and the display surface 51 are substantially opposed to each other and opened together with the housing 20 so as to form a substantially Z shape, and as shown in FIG. The side surface 22 which is the rear end side of the housing 20 is held so as to be pressed against the user's temporal region. In this state, the information light displayed on the display surface 51 of the image display unit 50 is emitted obliquely forward through the opening 21, and reflected toward the rear end side of the housing 20 by the reflection surface 61. The Thereby, the information displayed on the image display unit 50 is visually recognized as a virtual image in front of the combiner 60, that is, farther than the combiner 60 as viewed from the user.

The imaging device 40 mainly functions as a detection unit that detects an observation target existing in the actual visual field via the combiner 60. For this reason, as shown in FIG. 3, the imaging device 40 is provided at a position where an actual visual field landscape can be captured via the combiner 60 that spreads in the user's line-of-sight direction in the above-described use state. In the use state, the imaging device 40 captures a landscape in the user's line of sight and outputs the acquired image to a processing unit 73 (see FIG. 4) described later.
As the imaging device 40, for example, an analog imaging device using a photosensitive member such as a photosensitive film may be used, or a digital imaging device using an imaging device such as a CCD element may be used. In the present embodiment, a digital imaging device is used as the imaging device 40.

Next, an electrical configuration built in the housing 20 will be described with reference to FIG.
FIG. 4 is a block diagram showing an outline of the electrical configuration of the information terminal device according to the present embodiment. In this figure, the same components as those in FIGS. 1 to 3 are denoted by the same reference numerals.
As illustrated in FIG. 4, the housing 20 includes a first database 71, a second database 72, a processing unit 73 that executes various processes, an image display control unit 75, and the like.

  In the first database 71, images to be observed are registered. Details of the image registration of the observation target will be described later.

In the second database 72, as shown in FIG. 5, a plurality of behavior tables 300 are stored in association with each type of observation target (for example, dog, cat, houseplant, etc.). The behavior table 300 is a table in which display contents representing the state of the observation target are associated with each other according to the state of various parameters indicating the behavior.
For example, when the observation target is a plant, display contents expressing the state are registered according to the amplitude of the shaking of the leaves. Specifically, as shown in FIG. 6, the “amplitude” is divided into several levels, and display contents representing the state of the plant are set for each level. For example, display content such as “Today is quiet” is registered in “amplitude: level 1” indicating a situation where the wind is hardly blowing. In addition, “Amplitude: Level 5”, which indicates a situation where the wind is strong and the trunk and leaves of the tree are swaying, has display contents such as “Wind is hard and serious!”, “Help me.” be registered.
In this way, by registering the behavior table with “amplitude” as a parameter, it is possible to analyze the state of the plant, the state of fallen leaves, and the like due to the wind.

Further, for example, when the observation target is a living organism such as a dog, a cat, a hamster, or a baby, a behavior table is registered using parameters such as “movement speed” and “distance between living organisms” of the observation target.
For example, the “moving speed” is divided into several stages, and display contents representing the state of the organism are set according to each speed level. For example, display contents such as “exciting” and “fun” are registered in “speed: level 5” indicating a situation where the vehicle is running at a very fast speed. In addition, display contents such as “I'm tired” and “I'm sleepy” are registered in “Speed: Level 1” indicating the stopped state.

  Further, when there are two or more organisms, the “distance between organisms” is divided into several stages, and display contents representing the state of the organism are set according to each distance level. For example, in “distance: level 1” indicating a close situation where there is almost no distance between living organisms, for example, display contents such as “what happened” or “what to do next” are registered. Further, in “distance: level 5” indicating a situation where the distance is long, display contents such as “Where are you?” And “Hey” are registered, for example.

  Further, by combining the states of the two parameters, “moving speed” and “distance between organisms”, it is possible to set display contents that more accurately indicate the state of the organism. For example, when the distance between the two animals is some distance away and the two animals are moving at the same speed in the same direction, it can be determined that the player is chasing. In such a case, it is possible to set display contents such as “Mate” for the organism being chased and “Yadayo” for the organism being chased.

The processing unit 73 (see FIG. 4) includes a determination unit 731, a behavior detection unit 732, and a state analysis unit 733.
For example, the processing unit 73 includes a CPU (Central Processing Unit), ROM (Read
Only Memory), RAM (Random Access Memory), etc. are provided. A series of processing procedures for realizing the function of each unit described above is recorded in a ROM or the like in the form of a program, and the CPU reads the program into the RAM or the like and executes information processing / calculation processing. Functions such as the determination unit 731, the behavior detection unit 732, and the state analysis unit 733 are realized.
The determination unit 731 determines whether or not the observation target exists in the actual visual field via the combiner 60 based on the image acquired by the imaging device 40 that functions as the observation target detection unit.

The behavior detection unit 732 detects the behavior of the observation target based on the observation target image acquired by the imaging device 40. Specifically, the behavior detection unit 732 detects the behavior corresponding to the parameters of the behavior table illustrated in FIG.
For example, when the observation target detected by the determination unit 731 is a plant, the amplitude, period, and the like of the leaves of the plant are calculated based on the observation target images sequentially output from the imaging device 40.
In addition, when the observation target detected by the determination unit 731 is a living organism such as a dog, cat, hamster, or baby, the speed at which the observation target moves based on the images of the observation target that are sequentially output from the imaging device 40. And the moving direction is detected. Furthermore, when a plurality of observation targets are detected by the determination unit 731, the distance between the observation targets is calculated. Then, the detection result is output to the state analysis unit 733.

The state analysis unit 733 analyzes the state of the observation target based on the behavior detected by the behavior detection unit 732 and outputs the analysis result to the image display control unit 75. In the present embodiment, the state analysis unit 733 extracts the corresponding display content from the second database 72 based on the various parameters input from the behavior detection unit 732 (extraction unit), and displays the extracted display content as an image display. Output to the control unit 75.
The image display control unit 75 causes the image display unit 50 to display the display content output from the state analysis unit 733 of the processing unit 73. As a result, the display content displayed on the image display unit 50 is superimposed on the real image in the real field of view, that is, the observation target, as a virtual image by the combiner 60.

  The operation of the information terminal device 1 according to the present embodiment configured as described above will be described below.

[Initial registration]
Hereinafter, an initial registration process for registering an observation target will be described.
In the initial registration, as shown in FIG. 3, for example, the user holds the side portion 22 of the casing 20 of the information terminal device 10 in a used state so as to press it against the temporal region. Next, a shutter switch (not shown) provided on the side surface of the housing 20 is pressed in a state where the observation target can be confirmed in the real field of view through the combiner 60. Thus, an electrical signal indicating that the shutter switch has been pressed is input to the processing unit 73 (see FIG. 4) built in the housing 20.
When the processing unit 73 acquires an electrical signal indicating that the shutter switch has been pressed, the processing unit 73 captures an image currently captured by the imaging device 40. As a result, a landscape in the user's line of sight, that is, a landscape in which an observation target exists is captured by the imaging device 40 and is captured as an image into the processing unit 73.

Next, the processing unit 73 causes the image display unit 50 to display the captured image by outputting it to the image display control unit 75. This allows the user to check the captured image.
For example, when the user confirms whether the observation target is reliably captured as an image by directly confirming the display surface 51 of the image display unit 50, the user presses a registration button (not shown). As a result, an electrical signal indicating that the registration button has been pressed is input to the processing unit 73. When acquiring the electrical signal indicating that the registration button has been pressed, the processing unit 73 writes the previous image in the first database 71. As a result, the observation target is registered. Then, by repeatedly performing such operations and processes, it is possible to register various organisms as observation targets.

[After registration]
Next, the operation at the normal time of the information terminal device 1 after registration will be described with reference to FIG.
First, as shown in FIG. 3, in a state where the information terminal device 1 that has been put into use is held in the user's temporal region, the imaging device 40 that functions as an observation target detection unit The scenery is sequentially imaged and the acquired image is output to the processing unit 73.
When the determination unit 731 of the processing unit 73 acquires an image from the imaging device 40 (step SA1 in FIG. 7), the determination unit 731 determines whether or not an observation target exists in the actual visual field via the combiner 60 (step SA2).
Specifically, the determination unit 731 performs pattern matching between a landscape image in the user's line-of-sight direction acquired by the imaging device 40 and each observation target image registered in the first database 71. Then, when the landscape image acquired by the imaging device 40 can recognize a contour that matches the image of the observation target, it is determined that the observation target exists in the actual visual field via the combiner 60.

When it is determined that the observation target is present in the real field of view (“YES” in step SA2), the determination unit 731 outputs the information of the detected observation target to the behavior detection unit 732.
Based on the information on the observation target input from the determination unit 732, the behavior detection unit 733 detects the behavior of the observation target based on images sequentially input from the imaging device 40 (step SA3). For example, when two hamsters are detected as observation targets, the behavior detection unit 733 determines the moving direction, moving speed, and both of the two hamsters based on images sequentially output from the imaging device 40. Calculate the distance between them. These detection results are output to the state analysis unit 733.

  The state analysis unit 733 analyzes the state of the observation target based on the behavior input from the behavior detection unit 732 (step SA4), and outputs display contents corresponding to this state to the image display control unit 75 (step SA5). ). Specifically, the behavior table 300 registered corresponding to the hamster is acquired from the second database 72, and the acquired behavior table 300 is referred to, and it corresponds to various parameters input from the behavior detection unit 733. The display contents to be extracted are extracted. In the present embodiment, the moving direction, moving speed, and distance between the two hamsters are used as parameters, and the display content that matches these parameters is extracted from the behavior table 300 (see FIG. 5) of the second database 72. To do. Then, the state analysis unit 733 outputs the extracted display content to the image display control unit 75.

  The image display control unit 75 displays the display content input from the processing unit 73 on the image display unit 50. Thus, as shown in FIG. 8, the contents indicating the state of the hamster (here, “Mate” and “Yadayo”) are superimposed on the hamster existing in the real field of view by the combiner 60. (Step SA6).

As described above, the information terminal device according to the present embodiment has the following effects.
First, since the state of the observation target such as an animal or a plant is superimposed on the observation target existing in the real field of view by the combiner 60, the observation target such as a plant or animal and the state of the observation target are displayed. Can be displayed in an integrated manner. Thereby, there is an effect that the difference between the observation target and the state of the observation target is eliminated, and the state of the observation target can be easily communicated to the user.
Second, since the state of the observation target is analyzed based on the behavior of the observation target, it is possible to analyze and display the state of a living organism that does not emit sound. Thereby, it is possible to provide the user with the state and emotions of living things that do not emit sound.

The information terminal device according to the present embodiment has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within a scope not departing from the gist of the present invention are possible. included.
First, in the above-described embodiment, it is determined whether or not the observation target exists in the real field of view by performing pattern matching between the image acquired by the imaging device 40 and the image of the observation target registered in advance. Although it was determined, the determination is not limited to such an aspect, and for example, the determination can be performed by the following first other aspect, second other aspect, and the like.

As a 1st other mode, for example, it is provided with a direction information measurement part instead of the imaging device 40, and in the 1st database 71, instead of an image of an observation object, an arrangement position of an observation object, for example, Register location information consisting of latitude and longitude.
Then, the determination unit 731 included in the processing unit 73 is specified within a predetermined range determined based on the position and direction specified by the direction information measurement unit functioning as the observation target detection unit, for example, specified by the direction information measurement unit. By determining whether or not a pre-registered observation target exists within a fan-shaped range drawn in the direction specified by the azimuth information measurement unit with the centered position as the center, the observation target is Determine if it exists in the field of view.

As a second other aspect, for example, a transmitter with high directivity is installed on the observation target, and the front of the housing 20 when the information terminal device 1 is used (for example, the vicinity where the imaging device 40 is installed) ) Is provided with a receiver. And the determination part 731 of the process part 73 determines whether the observation object exists in a real visual field by determining whether the signal emitted from the transmitter was received by the receiver. In this aspect, the receiver functions as an observation target detection unit.
According to the first other aspect and the second other aspect as described above, whether or not the observation target exists in the real field of view through the combiner 60 without performing complicated processing such as pattern matching. Such a determination can be easily performed.
In addition, when a transmitter with high directivity is installed on the observation target as in the second other aspect, the behavior detection unit 732 determines the behavior of the observation target based on the signal from the transmitter, for example, Further, the moving speed of the observation object, the distance between the observation objects, and the like may be detected.
