摘要： In a CCD image sensor, a plurality of horizontal CCD registers are disposed adjacent to an image sensing area having matrix-arrayed image sensing cells and a plurality of vertical CCD registers. In the CCD image sensor, the channel impurity concentration of second horizontal CCD register, located away from the image sensing area, is more higher than that of first horizontal CCD register. With this feature, when the charges are transferred to the second horizontal CCD register across the first horizontal register, the residual charges in the first horiozntal CCD register are remarkably reduced.

摘要： A color image sensing system includes a CCD image sensor with an optical color filter. A CCD driver is provided to electrically drive the image sensor, which is attached to a vibration table serving as a swing-driver for moving the image sensor along a horizontal direction such that each cell of the image sensor shifts, in a frame period including first and second field periods, between four different sampling positions substantially aligned in the horizontal direction. During each field period, each cell is positioned at two sampling positions, wherein a brightness signal component is produced at one sampling position and color signal components are produced at these sampling positions. The distance between two sampling positions at which the brightness signal components of the first and second field images are produced is set to be half the horizontal pitch of the cells of the image sensor. The remaining two sampling positions of the four sampling positions are apart from each other by one-and-half times the horizontal cell pitch. A color frame image is thus reproduced by electrically adding the first and second field images to increase the number of picture elements to more than the actual number of cells, thereby improving the horizontal image resolution of the frame image and minimizing the generation of color moire in the frame image. The swing-drive operation of the image sensor is repeated in synchronism with the frame period.

摘要： A solid-state image sensor has an electrically floating carrier detecting electrode formed on a substrate, into which the signal carriers are transmitted, a sense amplifier circuit detecting the variation in a voltage of the electrode at the time of transferring the carriers, and a resetting electrode for resetting the potential of the electrode to a predetermined potential at every read-out period of the picture element section. A circuit arrangement for removing noise is provided with two switches which alternately become conductive in response to control pulse signals. The first switch becomes conductive during a first period within one picture element period. During the first period the CCD output signal contains an effective image signal component. The second switch becomes conductive during a second period during which the CCD output signal contains a reset noise component, thereby forcibly fixing the level of the reset noise signal to a DC reference potential so that reset noise can be removed.
