First Claim
Patent Images
1. An apparatus for detecting touch information and proximity information in a display apparatus, the apparatus comprising:
- a processor to control one or more processor-executable units;
an image extracting unit to extract a first image area associated with touch sensing using a first threshold and to extract a second image area using a second threshold, with respect to an obtained image; and
an image filtering unit to obtain a proximity image area associated with proximity sensing by removing an area associated with the first image area from the second image area.
