摘要：
The present invention allows a device to easily convert an on-screen image in HD format or SD format without increasing the processing load. The device according to an embodiment of the present invention uses the on-screen image D3 in which the number of horizontal pixels is set between horizontal pixel counts of HD format and horizontal pixel counts of SD format. Therefore, the device can utilize a relatively simple conversion ratio when converting the image in HD and SD format. This tremendously reduces the computational processing load. In addition, since the device uses the simple conversion ratio, the device can maintain the quality of the on-screen image D3.
