|20140375778||METHOD AND APPARATUS FOR ADJUSTING VIEWING AREA, AND DEVICE CAPABLE OF THREE-DIMENSION DISPLAYING VIDEO SIGNAL - 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.||12-25-2014|
|20120120206||METHOD, TV SET FOR DISPLAYING 3D IMAGE AND GLASSES - 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.||05-17-2012|
|20100097405||COLOR GAMUT MAPPING METHOD FOR MULTIMEDIA EQUIPMENT, A TELEVISION AND A COLOR PROCESSING APPARATUS - A color gamut mapping method for multimedia equipment is disclosed. This method performs color gamut mapping on a video signal received by the multimedia equipment and gives an output, wherein the video signal is in a first color color gamut while display light of the multimedia equipment is in a second color gamut. The color gamut mapping method for multimedia equipment comprises the steps of: converting the received video signal into a luminance signal and a chrominance signal, and calculating a two-dimensional plane according to the luminance signal and the chrominance signal, wherein the two-dimensional plane intersects the first color gamut to obtain a first region and intersects the second color gamut to obtain a second region; calculating location of a to-be-mapped point corresponding to the video signal in the first region according to the luminance signal and the chrominance signal of the video signal, and calculating a mapping point in the second region by making calculations on the to-be-mapped point to output a mapping point signal.||04-22-2010|
|20090251400||LCD DISPLAY METHOD - The present invention offers a display method, which can adjust the brightness of backlight by the brightness correction of the backlight, thereby not only decreasing the power consumption, but also solving the problem of blinking backlights. Especially, the display method of the present invention comprises: receiving an image signals, calculating the typical brightness of said image signal, calculating the brightness correction of the backlight according to the typical brightness of said image signal and the brightness of the backlight, adjusting the brightness of the backlight according to the brightness correction of the backlight, and adjusting said image signal. The display method of the present invention is correcting the image gray and contrast by applying the algorithm of slow changing of backlight according to the brightness scale of the input image, while adjusting the brightness of the backlight, therefore unchanging or increasing the subjective image effect, preventing the blinking of the backlight and improving the quality of the display.||10-08-2009|
|20090207318||Control unit, a video device including said control unit, and a control method - The present invention discloses a control unit, a video device employing said control unit and a control method thereof, wherein the control unit includes: a recognition device which is used to recognize the target in the target image; a calculation device which is used to calculate and transform the position coordinate of the recognized imaging target from the recognition device and output the position of the operation unit.||08-20-2009|
|20090115718||LIQUID CRYSTAL DISPLAY METHOD AND THE APPRATUS THEREOF - The present invention discloses a liquid crystal display method, which can adjust the brightness of different segments of backlight according to the different images. Especially, the present invention discloses a liquid crystal display method, which includes: receiving a image signal; analyzing the image signal; dividing the image into at least two image segments according to the analysis result of the image signal; dividing the backlight into at least two backlight segments according to the division result of the image; adjusting the brightness of the backlight in each backlight segment; adjusting the image signal in each image segment. The liquid crystal display method of the present invention divide the image and the backlight according to the image signal, while adjusting the brightness of the image and backlight in each segment to not only decrease the power consumption of the liquid crystal display, but also increase the contrast of the image signal, thereby improving the effect of liquid crystal display.||05-07-2009|
|20090002929||Electric apparatus and an operation method thereof - The present invention discloses an electric apparatus and operation method thereof. The electric apparatus includes: display unit to display the output content from said electric apparatus; operation unit used to operate said electric apparatus; the apparatus further includes: the primary indication unit, when the primary indication unit is started up, the operation unit is in visible status and otherwise the operation unit is in invisible status. The design of the present invention improves the front visual effect and the interactive performance of the electrical apparatus.||01-01-2009|
