Problems solved by technology

[0005] On the other hand, there is a problem with traditional connected component labeling methods: multiple objects that are adjacent to each other but different from each other are recognized as one object
To solve this problem, the prior art also includes an object separation operation for separating one object into two or more objects, and this additional operation may prolong the processing time of the touch image

Abstract

The invention provides a method and an apparatus for sensing touch. The present disclosure relates to a technology for assigning group labels during touch sensing, and more particularly to a technology for preventing two adjacent objects from receiving a same group label by searching for a valley when group labels are assigned and this allows labeling without performing any object separation process.

Description

technical field [0001] The present invention relates to a technique for sensing a touch unit arranged on a panel. Background technique [0002] Typically, position sensors are used as input devices for computers, personal digital assistants (PDAs), media players, video game consoles, home appliances, cordless phones, payphones, point-of-sale (POS) terminals, or automated teller machines, among others. One of the types of position sensors commonly used in this application area is a touch sensor and is readily found in input devices such as laptop computers. Typically, a user operates a touch sensor by moving a finger, stylus, or another stimulating device near the detection area of ​​the touch sensor. The stimulation device can generate a capacitive, inductive or other electrical effect by means of a bearing signal applied to the detection area, and can detect the position or proximity of the stimulation device to the detection area by means of the bearing signal. The posit...
