A touch sensitive processing apparatus includes: a driving circuit for connecting to multiple first electrodes, respectively; a sensing circuit for connecting to multiple second electrodes, respectively; and a processor configured for executing multiple sets of first round mutual capacitive detecting steps. Each set of the first round mutual capacitive detecting step further includes: having the driving circuit sending a driving signal to neighboring N first electrodes, where N is a positive integer larger than 1; and having the sensing circuit simultaneously detecting the driving signal via the second electrodes for generating multiple first round sensing information with respective to the set of first round mutual capacitive detecting step. Each of the first round sensing information corresponds to an intersection of central line of the N first electrodes and the second electrode.
