摘要： Disclosed in the present application are a method and device for determining the position of a viewer and adjusting a viewing area, and a device for displaying three-dimensional video signals, such that the position of a viewer in front of an electronic device can be accurately determined and the viewing area can be adjusted according to the specific position, enabling the viewer to be unaware of any sudden viewing change when watching 3D signals. The method for determining the position of the viewer is applied in an electronic device comprising a display screen capable of displaying three-dimensional video signals. The viewing areas of the electronic device include a three-dimensional display area and a non-three-dimensional display area. The method comprises: acquiring the image in front of the electronic device; judging whether the image contains the face image of the viewer; if the image contains the face image, identifying at least one feature in the face image to determine the position of the viewer; according to the at least one feature, determining whether the viewing area of the viewer is a three-dimensional display area or a non-three-dimensional display area.

摘要： A method for displaying 3D image is provided in the present invention. The method includes: 3D image signals, which comprise consecutive one frame of left-eye signal and one frame of right-eye signal, are received; the 3D image signals are processed by frequency multiplication, and n consecutive frames of left-eye signals and n consecutive frames of right-eye signals are obtained, n being the times number of the frequency multiplication and equal to or greater than 2; light-emitting diode (LED) driving signals drive the LED to display the n consecutive frames of left-eye signals and the n consecutive frames of right-eye signals; in the n consecutive frames of left-eye signals, the first frame of left-eye signal corresponds to an LED driving signal which is off, the nth frame of left-eye signal corresponds to an LED driving signal which is on, and in the n consecutive frames of right-eye signals, the first frame of right-eye signal corresponds to an LED driving signal which is off, the nth frame of right-eye signal corresponds to an LED driving signal which is on. The present invention also provides a TV set for displaying 3D image and a pair of glasses for viewing 3D image. By the present invention, the problem of crosstalk between leftimage and rightimage is solved, and backlight sources energy consumption and complete apparatus cost are reduced.
