Abstract:
1. A pointing device with multiple view angles, comprising: a first lens with a first view angle; a second lens with a second view angle; a sensing device comprising a first sensing matrix for sensing a reference point through the first lens in order to generate a first sensing image, and a second sensing matrix for sensing the reference point through the second lens in order to generate a second sensing image; and a processing device comprising a position calculation circuit for generating positional information according to the first sensing image and/or the second sensing image, and a switching control circuit for controlling the sensing device to sense the reference point through the first lens and/or the second lens according to the positional information; wherein when the first sensing image conforms to a first predetermined condition, the switching control circuit controls the sensing device to sense the reference point through the second lens; when the second sensing image conforms to a second predetermined condition, the switching control circuit controls the sensing device to sense the reference point through the first lens; wherein when the first sensing image conforms to the first predetermined condition, the switching control circuit turns off the first sensing matrix and turns on the second sensing matrix; when the second sensing image conforms to the second predetermined condition, the switching control circuit turns off the second sensing matrix and turns on the first sensing matrix.
