摘要： An image processing apparatus for converting different television standard signals includes an image pickup apparatus for selectively outputting an image signal of one of (i) a first television scheme and (ii) a second television scheme having a larger number of pixels than the first television scheme. An image pickup device is provided having a number of pixels corresponding to the first television scheme. A memory is provided for storing an output image signal from the image pickup device at a frequency corresponding to the first television scheme. An interpolation signal generating circuit is provided for generating an interpolation signal by adding a constant signal to a television signal corresponding to the second television scheme for compensating for an output of the second television signal. Video signal forming circuitry is also provided for forming a video signal by combining the signal read out from the memory and the interpolation signal generated by the interpolation signal generating circuitry.

摘要： An optical low-pass filter includes an optical member formed of a material capable of absorbing light in a particular wavelength range, e.g., an infrared range. The optical member has a plurality of ridge-like portions formed on at least one surface thereof at a predetermined pitch. The ridge-like portions comprise a phase type diffraction grating which has a low-pass filtering effect with respect to bundles of optical transmission rays passing therethrough.

摘要： In a camera control system capable of, in a video conference, remote surveillance or the like, issuing an instruction for a camera posture or the like, the user desires, on the moment in a simple way, an image with a small angle of view and a panoramic image are transmitted to a personal computer to be individually displayed. This arrangement constructs a system whereby the user can see not only a detailed image the user desires now but also an image surrounding the detailed image in substantially real time. Further, another arrangement for sensing an image reflected by a convex mirror which is constructed such that a central portion thereof is formed as a low-curvature surface and a peripheral portion thereof is formed as a high-curvature surface enables a panoramic image having a high resolution in a desired portion thereof to be obtained by using only one image sensor.
