Abstract:
1. An image signal processing apparatus for generating a stereoscopic pointer, comprising: a receiving unit configured to receive position information for designating a position of the stereoscopic pointer, said position information including depth direction of said stereoscopic pointer; a central processing unit (CPU) configured to generate horizontal pointer position signals based on the position information, and to set the horizontal position of the pointer in left and right channels to a horizontal position shifted so as to correspond to a parallax of the position of the stereoscopic pointer in the depth direction based on the depth direction of said position information; a display control unit configured to cause the display of the stereoscopic pointer based on the horizontal pointer position signal; a left pointer generation unit configured to generate a left channel pointer display signal based on left channel pointer position signals; a right pointer generation unit configured to generate a right channel pointer display signal based on right channel pointer position signals; a left channel mixing unit configured to mix the left channel pointer display signal with a left channel input image signal and generate a left channel output image signal; a right channel mixing unit configured to mix the right channel pointer display signal with a right channel input image signal and generate a right channel output image signal; and a combination processing unit configured to combine the left channel output image signal and the right channel output image signal and to generate an output image signal; wherein the left channel input image signal includes at least one of a left channel input luminance signal, a left channel input first color difference signal, and a left channel input second color difference signal, and the right channel input image signal includes at least one of a right channel input luminance signal, aright channel input first color difference signal, and a right channel input second color difference signal.
