    摘要: A 2D/3D image conversion system includes target phase value calculating means for calculating a target phase value per parallax calculation region based on a dynamic range of a preset target phase value and depth information per given unit area generated by depth information generating means; real phase value calculating means which calculates a current real phase value per parallax calculation region in a manner to progressively approximate a real phase value to a target phase value of a parallax calculation region with a corresponding previous real phase value and then determines a current real phase value per given unit area based on the current real phase value per parallax calculation region thus obtained; and phase control means for producing a first image signal and a second image signal from a signal residing in each given unit area of the 2D input image, the first and second image signals having a horizontal phase difference therebetween based on the current real phase value corresponding to the given unit area.

    摘要: A black level correction circuit for a video camera using a solid state image pickup device includes: means comparing an average luminance on each horizontal line in an optical black region of a reference black image with an average luminance on the corresponding horizontal line in an optical black region of an input image to thereby obtain a gain on the horizontal line in order to equalize an optical black level of the reference black image with an optical black level of the input image; means multiplying each of pixel values on each horizontal line in an effective pixel region of the reference black image by the obtained gain on the corresponding horizontal line; and means subtracting each pixel value obtained by the multiplication from a pixel value of the corresponding pixel in the effective pixel region of the input image.

    摘要: An infrared ray receiving module receives an infrared signal (transmitted by an image display device) generated on the basis of a signal representing switching between right and left eye images. An input signal type automatic judging unit and a field frequency detecting and L/R distinguishing unit acquire data relating to shutter timing of a left eye liquid crystal and a right eye liquid crystal in liquid crystal shutter glasses from the received infrared signal. An operation field frequency determining unit generates decision data relating to shutter timing to be fed to the liquid crystal shutter glasses on the basis of predetermined conditions from the data relating to shutter timing newly obtained in succession, and holds the generated decision data. A liquid crystal driving pulse generating unit can cause the liquid crystal shutter glasses to perform a shutter operation using the held decision data when no decision data is generated because the predetermined conditions are not satisfied. Consequently, it is possible to maintain the shutter operation even if the infrared signal is blocked.
