Abstract
Disclosed are a method of transmitting image data having a hybrid resolution and a method of generating a hybrid-resolution image. A main region of an original image is transmitted as a high-resolution image and the remaining regions are transmitted as a low-resolution background image. Accordingly, an amount of data to be transmitted is able to be reduced.

A method of transmitting hybrid-resolution image data, the method comprising:
- an operation (a) of receiving, by a processor, data of an original image from an image information generating device;
- an operation (b) of setting, by the processor, at least one first-resolution display region (hereinafter, referred to as a “high-resolution display region”) in the original image;
- an operation (c) of converting, by the processor, the high-resolution display region in the original image into image data (hereinafter, referred to as “high-resolution image data”) having a first resolution;
- an operation (d) of converting, by the processor, the data of the original image into background image data at a second resolution lower than the first resolution;
- and
- an operation (e) of transmitting, by the processor, the high-resolution image data or the background image data.
