Description

The utility model relates to the field of electronics.

A stationary electronic video enlarger is a hardware-software complex consisting of a monitor mounted on a camera tripod, a control, and in some cases a movable table. The operation of the device is provided by the imaging unit, which interacts and operates the software and hardware of the device.

One of the main functions and purposes of a stationary electronic video enlarger is image capture, changing the captured image depending on the user's requirements, for example, enlargement, color scheme change, other changes, and transfer of the changed image to the device monitor. That is, in fact, the device captures the image, converts it, if necessary, and transfers it to the monitor. In connection with the implementation of the described basic function when using the device, problems arise that require technical resolution.

Known device "Desktop video magnifier TOPAZ XL HD" (http://www.freedomscientific.com/Produccts/LowVision/TopazXLHD), (http://www.freedomscientific.com/content/documents/manuals/TOPAX/TOPAZ-XL- HD-Users-Guide.pdf), consisting of a monitor mounted on a movable tripod, controls, a processor, built-in backlight, a movable table placed horizontally at the bottom of the tripod, a video camera placed in the tripod body in such a way that it can capture images placed on a movable table. To work with the described device, the user places the text or object on the movable table so that the desired area is in the range of the device’s camera. The camera captures an image of a text or object, using the firmware integrated in the device, the image is converted and transmitted to a monitor.

The disadvantage of this device is to limit the number of objects that can be subjected to camera capture and, accordingly, enlarged and displayed on the monitor. The disadvantage is due to the fact that there is a limitation in the space between the camera of the device and the movable table. So objects having dimensions greater than a given distance cannot be examined using the described device. Moreover, the distance from the edge of the movable table to the tripod of the device also has a limited length, which together does not allow to consider objects having certain dimensions, in particular length, width, the height of which (any of them) exceeds the distance between the camera of the device and the movable table or exceeds distance from the edge of the movable table to the tripod of the device.

A device is known, described in patent document No. 7929013, issued by the patent office of the United States of America (USPTO), publication date July 20, 2006. This device, like the above, is equipped with a monitor, a movable table, a tactile-distinguishable governing body, and a camera located above the movable table. Like the device described above, the analogue under consideration has the same disadvantages that limit the number of objects that can be viewed using this device.

A device is known, described in patent document EP 2876601 A2, publication date 05/27/2015, issued by the European Patent Office, with the name "Vision enhancing device" (the original name in the language of the patent document "Vision enhancing device").

The device described in this patent document is implemented in the Optelec ClearView table magnifier (https://us.optelec.com/products/cvc-ocr-clearview-c-speech-24%E2%80%9D-high-definition.html )

This device partially eliminates the disadvantage of the analogues described above, since it has the ability to significantly increase the distance between the tripod of the device and the edge of the movable table, which allows to increase the dimensions of objects that can be examined using the described device.

This device is selected as a prototype of a utility model.

The device operates as follows. The user places an item on a movable table. The device’s camera captures the image and, depending on the command issued by the user through the elements of the control, the image forming unit of the device enlarges the image and transmits the enlarged image to the device’s monitor. If necessary, the user is able to ensure that the camera captures the device from items of increased length by moving the bracket to the side, which makes it possible to fully work with documents of a larger format than a movable table or with long objects, for example, a box.

Although this technical implementation partially eliminates the disadvantages of the analogs described above, it does not completely solve the problems of the possibility of capturing images of a number of objects that cannot fit in the camera capture zone.

In particular, if an object, for example, is rectangular in shape and it is necessary to capture an image printed on the ends of this object, this cannot be done because the distance between the movable table and the camera may be less than the length of the object and the object simply will not enter.

Also a disadvantage is the fact that with the help of the prototype we are considering, it is impossible to capture an image applied to an object having a large weight that can damage the device if this object is placed on a movable table.

Summarizing the disadvantages of the prototype should indicate that they are expressed in the presence of the dependence of image capture from objects on the size of the objects, their geometric shape and weight.

The problem to which the technical solution claimed as a utility model is aimed is to eliminate the disadvantages of the prototype, namely, to create conditions under which the dependence of the possibility of image capture by a stationary electronic video enlarger for people with disabilities from objects, on the size of the objects, their geometric shape and weight is eliminated .

The technical result of the claimed utility model is to increase the efficiency of an electronic stationary video enlarger, which is manifested in a significant expansion of the types of objects whose surfaces can be subjected to image capture, as a result of creating the ability to connect external information reading devices.

The specified technical result is achieved by introducing a new element into the device.

A stationary electronic video enlarger, consisting of an image forming unit that implements the image and transmits the enlarged image to the monitor, a monitor connected to it, characterized in that the image forming unit that implements the image and transfers the enlarged image to the monitor contains an integrated radio module.

Integrated into the image forming unit, which implements the image and transmits the enlarged image to the monitor, the radio module must provide the possibility of establishing a stable connection with well-known from the prior art information reading devices, for example, video cameras or devices containing video cameras, with the ability to transmit images over the air.

The implementation of the utility model is as follows.

If it is necessary to magnify an image from an object that cannot be viewed by a camera of a stationary electronic video enlarger, the user turns on any information reader that can be detected by its radio properties by a radio module integrated into the image forming unit, which implements the image and transfers the enlarged image to monitor, stationary electronic video magnifier.

A stable radio communication is established between the information reader and the image forming unit, which implements the image and transfers the enlarged image to the monitor. According to the signal from the image forming unit, which implements the image and transfers the enlarged image to the monitor, the stationary electronic video enlarger camera stops broadcasting to the monitor, and the video image from the information reader transmitted over the radio channel is received by the radio module integrated into the image forming unit, processed and broadcast on the monitor with the required magnification.
