Title: (EN) IMAGE PROVIDING SYSTEM CAPABLE OF PROVIDING AN IMAGE HAVING A RESOLUTION SUITABLE FOR A CORRESPONDING TERMINAL, AND A DEVICE FOR THE SAME AND AN IMAGE PROVIDING METHOD
(KO) 이미지 제공 시스템, 이를 위한 장치 및 이미지 제공 방법
Abstract:
(EN) PURPOSE: An image providing system, a device for the same, and an image providing method are provided to supply an image suitable for display specifications of a terminal even if accurate resolution information is not delivered from the terminal. CONSTITUTION: A service device (200) resizes an image according to one or more resolutions. If the image is requested by a terminal, the service device checks the resolution value of the terminal. The service device provides an image, which is resized according to the checked resolution value, to the terminal. If only pixel density information is transmitted from the terminal, the service device calculates a resolution value from the pixel density information. The service device provides an image, which is resized corresponding to the calculated resolution value, to the terminal.
