Abstract: An electronic apparatus and an object information recognition method by using touch data thereof are provided. A current touch sensing frame is obtained through a touch panel. The current touch sensing frame includes a plurality of frame cells respectively corresponding to a plurality of touch sensing units, and each of the frame cells has touch raw data. The frame cells include a target frame cell. A new cell value corresponding to the target frame cell is generated according to touch raw data of a plurality of adjacent frame cells adjacent to the target frame cell in the current touch sensing frame, so as to generate a transformation frame according to the new cell value. The transformation frame is transformed into a touch sensing image, and the touch sensing image is analyzed to recognize object information of a touch object.

Abstract: An electronic apparatus and an object information recognition method by using touch data thereof are provided. Touch sensing is performed in the case where no object touches a touch panel to obtain a specific background frame through the touch panel. A current touch sensing frame is obtained through the touch panel. Touch background data of a plurality of first frame cells in the specific background frame is respectively subtracted from touch raw data of a plurality of second frame cells in the current touch sensing frame to obtain a background removal frame including a plurality of cell values. The background removal frame is transformed into a touch sensing image. The touch sensing image is inputted to a trained neural network model to recognize object information of a touch object.
