Abstract: An image pickup device for use in a general image pickup input apparatus such as a video camera, an electronic camera and the like to prevent generation of a false signal or moires. The image pickup device includes an optical filter interposed between a taking lens and an image pickup element. Due to this, the image of an object light is formed by the taking lens at a given image forming position, and a spot image at the image forming position enters the optical filter as a divergent light in a given circle and is then guided through the optical filter to the image pickup element. This can remove space frequency components corresponding to the pixel pitch of the image pickup element and prevent the optical aberrations from being unstabilized.

Abstract: For filter video signals a median selector is used to the inputs of which the sample values of a first pixel and other neighboring pixels. These other pixels lie in the line direction (horizontal) and in a direction perpendicular thereto (vertical) next to the first pixel. The filtering is improved if at least one additional pixel is provided in each of those directions, providing a cruciform filter window. A still further improvement is provided if pixels which immediately preceed or follow the first pixel in the time-dimension (i.e. pixel values from a previous or following picture) are also supplied to the median selector. By utilizing interpolated sub-pixels close to the central or first pixel, disturbances, not only from noise or drop-out, but also from chrominance cross-talk, can be mitigated or avoided.

Abstract: A still video camera provided with a mode selector to select an operation mode, a trigger generator to generate a trigger signal and a video recorder to record a visual image of the subject and to reproduce the recorded image. When the record-play mode is selected by the mode selector, the video recorder responds to the trigger signal from the trigger generator to record a frame of the visual image of the subject. The recorded frame of the visual image of the subject is then played back. This sequence can be repeated at the direction of the operator, at predetermined time intervals, or in response to a sound amplitude greater than a predetermined level. The still video camera is also capable of recording and playing back sound to accompany the still picture.

Abstract: A video signal obtained by a solid-state image pickup device is supplied to a display apparatus to display an image. The number of the pixels of the solid-state image pickup device is smaller (e.g., 1/4) than that of the screen of the display apparatus. The transfer clock of the solid-state image pickup device is so controlled that the video signal output therefrom corresponds to an image displayed at the region of 1/4 of the reproducing screen. The video signals from four solid-state image pickup devices are compounded so as to display an image composed of four divided images on one screen. A synchronizing signal which is a reference for the transfer clock is transmitted from the display apparatus so as to synchronize the four video signals. In another mode, the transfer clock is so controlled as to enlarge a video signal which corresponds to an image for the 1/4 region of the reproducing signal and display the image on the entire part of the reproducing screen.

Abstract: Supplied selectively to a recording system circuit of a VTR are a first component signal comprising three primary color signals R, G and B and a second component signal comprising a luminance signal Y and two types of color difference signals P.sub.B and P.sub.R. The first and the second component signals pass through a group of LPFs (1, 2, 3) having the same pass characteristics and then are A/D converted at the same sampling clock. The component signal converted into a digital signal is applied to a matrix circuit 11.
