The invention discloses a method for correcting an image sensor, which comprises the following steps: correcting a brightness amplification factor used by the image sensor when the image sensor is started; and truncating at least one picture frame (but not all) from a plurality of picture frames predetermined for image processing in unit time whenever a fixed cycle is finished after the start of the image sensor, and correcting the brightness amplification factor according to the truncated picture frame. The method precludes the possibility that the screen of an optical touch panel is obscured by an object in advance to keep parameter values used by the image sensor accurate by running correction programs in the starting process, and continuously keeps the accuracy of the brightness amplification factor on the premise of not affecting the display quality of the screen.

The invention discloses an object sensing system and a control method thereof. The object sensing system comprises an indication plane, a first image sensing unit and a plurality of light-emitting units and processing units. The indication plane is used for the object to indicate a position. The first image sensing unit is arranged at a first corner of the indication plane. The plurality of light-emitting units are arranged around the indication plane. Each light-emitting unit corresponds to at least one of the plurality of working hours, each working hour is respectively provided with at least one exposure time, and each exposure time respectively corresponds to at least one of the light-emitting units. The processing units are electrically connected with the first image sensing unit and the light-emitting units. The processing units control the light-emitting units to emit light according to each exposure time and control the first image sensing unit to sense the first image concerning ...
