INPUT DEVICE AND INFORMATION TRANSMITTING METHOD THERE OF

摘要

An information transmitting method of an input device, according to an embodiment of the present invention, comprises the steps of: computing the total brightness of a frame as a unit screen of a scanned image; computing the average brightness of the frame using the computed total brightness; and transmitting information about the computed average brightness to a display device. [Reference numerals] (S3101) Mouse mode; (S3103) Is a scan start request signal received?; (S3105) Enter a scan mode; (S3107) Start a scan; (S3109) Detect the coordinates of a frame; (S3111) Store the detected coordinates of the frame; (S3113) Compute the total brightness of the frame; (S3115) Compute average brightness; (S3117) Transmit the computed average brightness to a display device; (S3119) Is a lift off signal generated?
