Patent ID: 8872776

Claim:
A method for analyzing two-dimension (2D) sensing information, comprising: obtaining a first 2D sensing information including a plurality of first one-dimension (1D) sensing informations, wherein each first 1D sensing information includes a plurality of first values; performing one accumulation conversion on each first 1D sensing information to constitute a second 2D sensing information, wherein the accumulation conversion includes one of a forward accumulation and a backward accumulation to convert the plurality of first values into a plurality of second values, and the other one of the forward accumulation and the backward accumulation to convert the plurality of second values into a plurality of third values; wherein the forward accumulation includes converting each first value in each first 1D sensing information into an accumulation of the each first value and all other first values preceding the each first value to generate a corresponding second value in a corresponding second 1D sensing information, and the backward accumulation includes converting each second value in each second 1D sensing information into an accumulation of the each second value and all other second values following the each second value to generate a corresponding third value in a corresponding third 1D sensing information, wherein the second 2D sensing information includes these third 1D sensing informations; and performing an image segmentation on the second 2D sensing information to determine each touch related sensing information in the second 2D sensing information.
