摘要： Liquid crystal for a right eye and liquid crystal for a left eye are not positioned in one plane, but are positioned to incline at an angle of 5°. To be concrete, both liquid crystal are inclined so that they become closer to the viewer's face as making toward the side of the face from the middle of the forehead. The inclination of liquid crystal as above-described to set the preferential direction of visual view of liquid crystal to be horizontal leads in that the direction by which the high contrast of liquid crystal can be obtained is toward the 3D display. It diminishes a phenomenon like cross-talk and allows the viewer to view the appropriate stereoscopic image. Liquid crystal for a right eye and liquid crystal for a left eye have the same construction. These liquid crystals make contrast with each other and then they are mounted on the liquid crystal shutter glasses portion. This makes it possible for each electrode to position in the center of liquid crystal shutter glasses portion. The construction in which the electric circuit is in the center of the liquid crystal shutter glasses portion makes it easy to make electric contact between the circuit and the electrode.

摘要： A left eye image signal and a right eye image signal which constitute a three-dimensional image are produced from a two-dimensional image signal. The horizontal phase of the produced left eye image signal is shifted, and the horizontal phase of the produced right eye image signal is shifted. Character signals are respectively mixed with the left eye image signal and the right eye image signal. A composite image comprising the three-dimensional image and the character signal is displayed on the basis of the left eye image signal with which the character signal is mixed and the right eye image signal with which the character signal is mixed.

摘要： A method of converting two-dimensional images into three-dimensional images. When the movement of a main image is fast, a main image signal is written into field memories for each field. When the movement of the main image is slow, the main image signal is written into the field memories at intervals of a predetermined number of fields. An image to be read out as a sub-image from the field memories is determined on the basis of the speed of the movement of the main image.

摘要： An amplification signal of a difference signal between a sensor signal and an offset signal to be variably set is converted into a digital signal. The sensor signal is in accordance with shake of an imaging device and outputted from a sensor. The first digital signal is obtained while a conversion ratio between the difference signal and the digital signal is set to a first conversion ratio. The second digital signal is obtained while the conversion ratio is set to a second conversion ratio. In relation to a certain difference signal, the value of the second digital signal is smaller than that of the first signal. The offset signal is updated based on the second digital signal. The shake information is generated based on the first digital signal.

摘要： A motion vector holding unit 61 holds motion vector information with respect to a backward reference frame detected beforehand and received from a motion compensation unit 60. A motion vector calculation unit 63 calculates multiple motion vectors for each macro block defined in a coding target frame with reference to the motion vector information with respect to the backward reference frame held by the motion vector holding unit 61 according to each calculation mode of a set of different calculation modes. A motion compensation prediction unit 64 performs motion compensation using motion vectors obtained for each calculation mode, thereby creating predicted images. The predicted images are output to a coding amount estimation unit 65. The coding amount estimation unit 65 estimates the coding amount of the subtraction image, which is the subtraction between the predicted image and the original image, for each calculation mode. A motion vector selection unit 67 makes a comparison between the coding amounts of the subtraction images, and selects the motion vector which provides the smallest coding amount.

摘要： A display device has: an RGB-RGBW conversion circuit that converts RGB signals fed thereto into RGBW signals; a display panel that has a plurality of dots each composed of four, namely R, G, B, and W, unit pixels and that displays an image based on the RGBW signals; a defect position specifier that specifies, if a unit pixel is found defective, a position of the defective pixel on the display panel; and a conversion rate controller that controls the rate at which, when the RGB signals are converted into the RGBW signals, the RGB signals are converted into a W signal according to the position of the defective pixel. If the defective pixel is a W pixel, the conversion rate for pixels adjacent thereto is made lower than the standard conversion rate set for the entire display panel.
