摘要：An exemplary detecting method for a photo-sensor touch panel and a touch-
sensitive electronic apparatus using the same are provided. In aforementioned method, an image frame is obtained by scanning the photo-sensor touch panel. Then, a distribution area of data points in the image frame each having a brightness between a predetermined brightness and a first threshold brightness is defined as a first sensing area, and a distribution area of data points in the image frame each having a brightness between the predetermined brightness and a second threshold brightness is defined as a second sensing area. Afterward, it is determined that whether a real touch母系氏族
probably/really occurred according to a relative distance between one of first data points and corresponding one of second data points. The first data points located in the first sensing area, and the second data points located in the second sensing area.
