Referring to FIG. 4, (1) an image is an image of a photographed original, which is an image formed by the first device 200; The first device 200 sets the number of frames in various cases based on the image 1 formed first by the first device 200, and a transmission image is generated for each of the cropping settings and transmitted to the second device 300. Accordingly, in order for the image transmission apparatus 100 provided in the first apparatus 200 to solve the problem of image quality deterioration and to continuously generate a transmission image, it is desirable that the resolution of the image be as high as the highest specification level Do.

① The video image is formed as a transmission image and then the encoded image is the same as the ② image. After the user selects the 'B' portion of the image, the transmission image generated through the craps setting is the same as the ③ image, The transmission image generated after the user selects the 'C' part is the same as the image of the ④ image, and the transmission image generated after the user selects the 'D' part of the image through the craps setting, same.

5 is an exemplary diagram showing an example of the operation of the monitor unit of FIG.

5 shows an example of a mobile robot image transmission system. In other words, each screen of FIG. 5 shows a result of receiving and displaying an image transmitted from a mobile robot for capturing an image, which is a configuration of a monitor unit 310 for confirming a user's image in the mobile robot image transmission system.

In the screen of Fig. 5, if the user wishes to enlarge the 'A' portion of the screen more closely and to observe more closely, the user can form the information 'A' of the screen and transmit it to the mobile robot.

At this time, (1) the image corresponding to the screen is transmitted from the mobile robot, and may be a real-time photographed image or a stored image that is continuously photographed while the mobile robot stops moving.

Fig. 6 is an exemplary diagram showing another example of the operation of the monitor unit of Fig. 3. Fig.

Referring to FIG. 6, the mobile robot 1 confirms the information selected by the user on the 'A' portion of the screen as an executed external command, and performs the execution based on the confirmed external command. That is, based on the received external command, (1) set a crop to extract a part of the image from the image corresponding to the screen, and (2) transmit the image of a certain region extracted through the crop setting to a predetermined resolution of the transmission bandwidth And generates an image. Then, the mobile robot compresses the generated transmission image, and transmits the compressed transmission image to the user management system via the communication network.

Of the monitor unit 310 of the user management system, the image displayed on the ① screen is a newly transmitted image from the mobile robot. In this way, ① the image displayed on the screen is the image obtained by enlarging the 'A' portion of the previous ① screen without degrading the image quality.

FIG. 7 is a flowchart illustrating an operation of the image transmission apparatus shown in FIG. 1 as an example.

Referring to FIG. 7, the image transmission apparatus 100 receives an image (S1).

Thereafter, the image transmission apparatus 100 determines whether an external command related to the crap setting for a partial area of the image is received from the second device 300 (S3).

In step S3, when no external command is received from the second apparatus 300, the image transmission apparatus 100 generates the image captured by the first apparatus 200 as a transmission image (S5).

Thereafter, the transmission image generated in step S5 is compressed and the output is transmitted to the second device 300 (S9).

Thereafter, when it is necessary to continuously execute the image transmission process for delivering to the second device 300, the execution of each step described above is repeated (S11).

In step S3, when an external command is received from the second device 300, the image transmission device 100 determines whether the image to be edited is a stored image from the second device 300 (S3- One).

If it is determined in step S3-1 that the object of image editing requested by the second device 300 is not an image stored in the first device 300, As an image (S3-2).

Thereafter, the transmission image generated in step S3-2 is transmitted to the second device 300 through steps S7 through S9.

If the image editing object requested by the second device 300 is stored in step S3-1, the stored image is extracted (S3-1-1).

In step S3-1-2, a part of the stored image extracted in step S3-1-1 is generated as an image for transmission based on an external command requested from the second device 300. FIG.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.

In addition, since the present invention is intended to prevent image quality deterioration due to enlargement of a specific portion of an image when a user wants to enlarge a selected region of an input image, the possibility of commercialization or sales is sufficient, This is an invention that is industrially applicable because it is practicable.
