Description

Electronic image magnifier with automatic conversion mode

The present invention automatically detects the use or non-use of a user when the user uses or does not use the apparatus through the presence or absence of a subject placed on the table. When the user uses the apparatus, the apparatus operates in an enlargement mode for outputting an enlarged image of the subject to a monitor. The present invention relates to an electronic magnifier having a function of automatically switching a use mode, which is operated in a publicity mode for outputting a previously stored publicity image to a monitor, thereby eliminating the inconvenience of the user due to mode switching.

Due to the development of electric and electronic technology and image processing technology, an electronic expander is being widely used to elec- tronically or low-visionally view a subject, such as a book, a promotional item, or a document, electronically and display it as a monitor.

In accordance with the spread of the electronic expander, the electronic enlarger is provided on the desk which is used by the customer so that the customer can use the social infrastructure service efficiently.

Such an electronic magnifier is a structure in which when a user puts up a subject to be enlarged on an upper part of a table provided integrally with the user, the subject is photographed with a camera to acquire the subject image, and the enlarged image is output to a monitor.

On the other hand, the electronic magnifier can be used as a publicity mode showing a publicity image of announcements, campaigns, advertisements, etc. related to a place where the user is not using the mobile phone since the mobile phone can be used as multimedia.

That is, the electronic magnifier can be used in a magnification mode for enlarging a subject placed on the upper part of the table and a publicity mode for displaying a publicity image separately stored in the storage.

However, in order to simultaneously perform the enlargement mode and the publicity mode, the main body needs to have a mode switching button separately, and it may inconvenience that the user directly manipulates the mode switching button to select one of the two usage modes.

Therefore, it is necessary to improve the use mode switching method applicable to the electronic expander so that the enlargement mode and the publicity mode are automatically switched to eliminate the inconvenience of use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an electronic expander having an automatic mode for use in accordance with a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1, an electronic magnifier having an automatic mode for use mode switching according to a preferred embodiment of the present invention includes a main body 10, a camera 20, an image processor (not shown), a storage medium (not shown), a monitor (30), a detection sensor (40), and a mode switching processor (not shown).

First, the main body 10 is seated on an upper part of a table D provided in a government office or the like.

That is, the main body 10 includes a table 11 on which a subject is placed on a table D, a support frame 12 vertically installed on the upper rear end of the table 11, And a main frame 13 installed therein.

Next, the camera 20 is installed on the main frame 13 of the main body 10 and captures an image of a subject placed on the table 11 to acquire an image of the subject.

At this time, it is preferable that the camera 20 is installed on the lower front side of the main frame 13 so as to shoot toward the table 11.

Next, the image processor generates an enlarged image by enlarging a subject image, which is installed inside the support frame 12 of the main body 10 or the main frame 13,

At this time, the image processor enlarges the subject image so that the elderly person or the low vision person can recognize it, but enlarges the image while minimizing the image quality degradation for the quality of the enlarged image. However, the image processor may include a processing function for various image effects in addition to the enlargement function.

Next, the storage medium is provided in the support frame 12 or the main frame 13 of the main body 10 to store the promotional images.

That is, the storage medium is for storing promotional images such as notices, campaigns, advertisements, etc. related to the place where the electronic magnifier is provided so that the electronic magnifier can operate in a publicity mode when the user does not use the electronic magnifier.

The storage medium may be an internal storage medium built in the main body 10 or an external storage medium detachable to the main body 10 or an external device separately connected to the main body 10.

The publicity image may be composed of a moving picture file composed of a plurality of frames or a picture file composed of one frame. That is, the publicity image stored in the storage medium can be output as a moving picture through the monitor 30 or in the form of a photograph.

Next, the monitor 30 is installed in the main frame 13 of the main body 10 and outputs a magnified image generated by the image processor or a PR image previously stored in the storage medium.

That is, when the use mode is the enlargement mode, the monitor 30 outputs the enlarged image to the screen, and when the use mode is the promotion mode, the monitor 30 outputs the promoted image to the screen so that the user can view the enlarged image.

At this time, the monitor 30 may have only an output function like a general monitor if necessary, and may have an output function and an input function at the same time as a touch screen.

The main body 10 on which the monitor 30 is installed is additionally provided with a control button for controlling the power of the electronic magnifier according to the user's operation or for controlling the magnified image or the publicity image output to the monitor 30. [

Next, the detection sensor 40 is installed on the main frame 13 of the main body 10, and detects a presence or absence of a subject in the photographing area of the camera 20, which is the upper part of the table 11, .

At this time, the detection sensor 40 is installed on the lower surface of the main frame 13 so as to face the table 11 in order to detect whether the subject exists on the upper side of the table 11 through the detection sensor 40.

The detection sensor 40 may be composed of a distance sensor for discriminating through the distance so as to accurately determine whether a subject exists or a light amount sensor for discriminating through a light amount difference.

That is, the distance sensor can detect whether a subject exists in the upper portion of the table 11 using the time difference between the time when the light is irradiated toward the table 11 and the time when the light is reflected from the table 11.

The light amount detection sensor can detect whether the subject exists on the upper side of the table 11 by using the difference between the amount of light irradiated toward the table 11 and the amount of light reflected from the table 11. [

The mode switching processor detects the presence or absence of the subject through the sensing signal output from the sensing sensor 40 and is installed inside the supporting frame 12 or the main frame 13 of the main body 10, It automatically converts the usage mode.

That is, the mode switching processor automatically determines the use state of the electronic magnifier on the basis of the sensing signal input by the sensing sensor 40 without the user's intentional manipulation, thereby operating the magnifying mode or the publicity mode.

At this time, the enlargement mode is a usage mode in which an enlarged image obtained by enlarging the subject image is output to the monitor 30, and the camera 20 is turned on. The publicity mode is a usage mode in which a publicity image is output to the monitor 30, and the camera 20 is turned off.

The mode switching processor includes an input unit for receiving the sensing signal output from the sensing sensor 40 and a sensing unit for sensing a presence or absence of a subject by comparing sensing values according to the sensing signals input from the sensing unit 40, And an execution unit for switching the use mode of the electronic magnifier to the enlargement mode or the promotion mode according to the discrimination signal generated by the discrimination unit.

2, the input unit receives the distance detection signal of the distance detection sensor, and the determination unit compares the detection distance according to the distance detection signal with a preset reference distance to discriminate And the execution unit switches the use mode of the electronic magnifier to the enlargement mode or the use mode according to the discrimination signal.

At this time, if the detection distance is smaller than the reference distance, the determination unit determines that the subject exists in the upper portion of the table 11, and otherwise determines that the subject does not exist in the upper portion of the table 11.

3, the input unit receives the light amount detection signal of the light amount detection sensor, and the determination unit compares the light amount difference according to the light amount detection signal with the predetermined reference light amount difference And the execution unit switches the use mode of the electronic magnifier to the enlargement mode or the use mode according to the discrimination signal.

At this time, if the light amount difference is smaller than the reference light amount difference, the determination unit determines that the subject exists on the upper side of the table 11, and otherwise determines that the subject does not exist on the upper side of the table 11.

Here, auxiliary means for assisting the mode switching processor to more accurately determine whether the subject exists in accordance with the sensing signal sensed by the sensing sensor 40 may be further provided on the table 11 of the main body 10.

That is, as shown in FIG. 4, in the upper portion of the table 11, the sensing distance sensed by the distance sensing sensor is set to a predetermined depth so that the difference between when the object is present and when the object is present is clearly shown, do.

In this case, the recessed space 50 is suitable for a case in which the thickness of the subject is not relatively large, so that there is almost no difference in sensing distance between when there is no subject and when there is no subject, and the presence or absence of the subject can not be accurately discriminated.

Therefore, when the depth of the recessed space 50 is absent, the depth of the object is added to the sensing distance, thereby increasing the sensing distance difference between when the object is present and when there is no object, thereby accurately determining whether or not the object exists.

However, it is preferable that the recessed space 50 is formed on the area of the table 11 where the distance detection sensor senses, and the depth thereof is formed as deep as possible within a designable range.

As shown in FIG. 5, in the upper part of the table 11, a difference in amount of light sensed by the light amount sensor is detected by a light absorbing member (not shown) having a relatively low light reflectance so that the difference between when the object is present and when the object is present 60 are installed.

At this time, the light absorbing member 60 is suitable for the case where the light reflectance of the subject is relatively high, so that there is almost no difference in light amount between when there is no subject and when there is no subject, and the presence or absence of the subject can not be accurately discriminated.

Therefore, the light absorbing member 60 greatly reduces the light reflectance when there is no subject, thereby making it possible to accurately discriminate the presence or absence of the subject by increasing the sensing distance difference between when the subject is present and when there is no subject.

However, it is preferable that the light absorbing member 60 has a black color having a relatively low light reflectance and a relatively high light absorption rate as compared with other colors.

Meanwhile, although not shown, if the detection sensor can simultaneously detect the detection distance and the light quantity difference, the recessed space 50 and the light absorbing member 60 can be provided at the upper portion of the table 11 at the same time.

That is, the recessed space 50 may be formed at a predetermined depth on the upper surface of the table 11, and the light absorbing member 60 may be provided on the inner bottom surface of the recessed space 50. Therefore, it is possible to detect the presence of the object more accurately by simultaneously detecting the detection distance and the light amount difference.

As described above, according to the present invention, the electronic expander having the automatic switching function of the use mode can automatically eliminate the inconvenience of the user due to the switching of the use mode as the use mode is automatically converted into the enlarged mode or the publicity mode The public relations function through the public relations mode can be expanded effectively.

The above-described embodiments are merely illustrative, and various modifications may be made by those skilled in the art without departing from the scope of the present invention.
