a communication circuit; at least one processor operatively connected to the imaging device and the communication circuit; and a memory operatively connected to the processor, for storing a command. ## Claims ### Claim 1 An electronic device comprising: an imaging device configured to generate image data; a communication circuit; at least one processor operatively connected to the imaging device and the communication circuit; and a memory operatively connected to the processor to store instructions, wherein the instructions cause, when executed, the processor to: receive first image data including a first image from the imaging device, the first image comprising text, transmit the first image data to an optical character recognition (OCR) server through the communication circuit, receive a first text data, including a first text recognized from the first image data, from the OCR server through the communication circuit, receive second image data, including a second image from the imaging device, the second image including a first region that overlaps a part of the first image and a second region that does not overlap the first image; and compare the first image and the second image, transmit a second text data and a part of the second image data, not all of the second image data, to the OCR server through the communication circuit, and receive a third text data, including a third text recognized from the transmitted second text data and the part of the second image data, from the OCR server through the communication circuit, wherein the second text data is a text data including at least a part of the first text data corresponding to the first region of the second image that overlaps the part of the first image, and wherein the part of the second image data represents the second image data corresponding to the second region. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the first text data has a javascript object notation (JSON) format. ### Claim 3 (depends on 2) The electronic device of claim 2, wherein the first text data includes data about at least one coordinates related to the first text in the first image. ### Claim 4 (depends on 1) An The electronic device of claim 1, further comprising: a display configured to output an image recognized through a camera, wherein the imaging device is the camera, and wherein the instructions cause, when executed, the processor to: capture the first image output through the display in response to a user input for executing an application. ### Claim 5 (depends on 4) The electronic device of claim 4, wherein the first text includes a first currency unit, and wherein the instructions cause, when executed, the processor to transmit the first text to an external server, receive a second currency unit obtained by changing the first currency unit to a specified unit from the external server, and output the second currency unit through the display. ### Claim 6 (depends on 4) The electronic device of claim 4, wherein the instructions cause, when executed, the processor to: transmit the first text to an external server, and receive a first translated text, obtained by converting the first text into a specified language, from the external server and output the first translated text through the display. ### Claim 7 (depends on 6) The electronic device of claim 6, wherein the instructions cause, when executed, the processor to: transmit the third text to the external server, and receive a second translated text, obtained by converting the third text into the specified language, from the external server and output the second translated text through the display. ### Claim 8 (depends on 4) The electronic device of claim 4, wherein the first text includes a first physical quantity unit, and wherein the instructions cause, when executed, the processor to transmit the first text to an external server, receive a second physical quantity unit obtained by changing the first physical quantity unit to a specified unit from the external server, and output the second physical quantity unit through the display. ### Claim 9 (depends on 1) The electronic device of claim 1, wherein the first image comprises an image taken at a first point in time, the second image comprises an image taken at a second point in time, and the second image data comprises data visible in the second image and obscured in the first image by an external object. ### Claim 10 A method for recognizing characters in an electronic device comprising: receiving first image data including a first image from an imaging device, the first image comprising text; transmitting the first image data to an optical character recognition (OCR) server through a communication circuit; receiving a first text data, including a first text recognized from the first image data, from the OCR server through the communication circuit; receiving second image data, including a second image from the imaging device, the second image including a first region that overlaps a part of the first image and a second region that does not overlap the first image; comparing the first image and the second image; transmitting a second text data and a part of the second image data, not all of the second image data, to the OCR server through the communication circuit; and receiving a third text data, including a third text recognized from the transmitted second text data and the part of the second image data, from the OCR server through the communication circuit, wherein the second text data is a text data including at least a part of the first text data corresponding to the first region of the second image that overlaps the part of the first image, and wherein the part of the second image data represents the second image data corresponding to the second region. ### Claim 11 (depends on 10) The method of claim 10, wherein the first text data has a javascript object notation (JSON) format. ### Claim 12 (depends on 11) The method of claim 11, wherein the first text data includes data about at least one coordinates related to the first text in the first image.
