    摘要： A three-dimensional image display apparatus of the invention can be easily operated by the operator while a three-dimensional image created by the apparatus is observed by him. A depth information maximum value acquisition circuit acquires depth information contained in a first image signal. A parallax control circuit controls the parallax amount of a second image signal on the basis of depth information contained in the first and second image signals such that an image corresponding to the second image signal can be three-dimensionally displayed in front of an image corresponding to the first image signal. A three-dimensional image synthesizer synthesizes the first and second image signals which has been controlled by the parallax control circuit, on the basis of the parallax amount of each image signal, such that images correspond to that the first and second image signals in the three-dimensional display space.

    摘要： A video signal processor for preventing image damage resulting from when a first signal and a second signal are converted into each other. When a first signal (an interlaced scanning format signal) is inputted, according to a mode discriminating signal from a mode discriminator, a mixer/selector receives the motion detecting signal from the mode discriminator, adaptively mixes both outputs of a delay circuit and a line interpolating filter (IPF) and uses the combined outputs as an interpolation signal. When a second signal (a progressive scanning format signal converted to an interlaced scanning format signal) is inputted, the mixer/selector selects either the output of the second signal or the output of a delay circuit according to the mode discriminating signal and the field indexes from the mode discriminator and makes it as an interpolation signal. When an input signal is converted from a first signal to a second signal, the mixer/selector receives the motion detecting signal from the mode discriminator and selects the output from the line interpolating filter as an interpolation signal (intra-field interpolation) for at least one field of the changed-over signal according to the mode discriminating signal from the mode discriminator.
