摘要： A color representation technique to be effectively applicable to a pixel shifted arrangement to realize high sensitivity and high resolution is provided by using a dipersive prism or diffraction.A dispersive element is provided for an image sensor in which photosensitive cells are arranged to be shifted from each other by a half pitch both horizontally and vertically. The dispersive element makes at least G rays fall straight down to a pixel right under itself and also makes either R rays or B rays incident on an adjacent pixel. Meanwhile, a photosensitive cell, for which no dispersive element is provided, receives directly incident light, too. Color information can be obtained by making computations on photoelectrically converted signals provided by these pixels.

摘要： A solid-state image sensor comprises unit pixels each having a photoelectric conversion element for converting incident light into electric signal charge and then storing the signal charge obtained through such photoelectric conversion, an amplifying element for converting into an electric signal the signal charge stored in the photoelectric conversion element, and a select switch for selectively outputting the pixel signal from the amplifying element to a signal line. The image sensor further comprises a reset circuit in each of the unit pixels for resetting the photoelectric conversion element every time a pixel signal is outputted from the relevant unit pixel. The photoelectric conversion element is reset every time a pixel signal is outputted, so that a pre-reset signal and a post-reset signal are delivered from each unit pixel and then are transferred via a common path, and the difference between such signals is taken to suppress not only the fixed pattern noise derived from characteristic deviation in each unit pixel but also vertically correlated fixed pattern noises of vertical streaks.

摘要： A CCD image sensing device has vertical shift registers (22), a horizontal shift register (3A), a horizontal transfer gate (4), a horizontal shift register (3B), a smear gate (6), a smear drain region (7) and a channel stop region (8) arranged in that order on an n-type substrate (N-Sub). A p-well region underlying the vertical shift registers (22), the horizontal shift register (3A), the horizontal transfer gate (4), the horizontal shift register (3B) the smear gate (6), the smear drain region (7) and the channel stop region (8) is doped in a high impurity concentration to stabilize the potential of the p-well region at a potential substantially equal to that of the channel stop region (8), i.e., ground potential (GND). Consequently, no hole storage region is formed in the p-well and hence the deterioration of the signal transfer performance can be prevented. Since no hole-depletion region is created, no dark current due to avalanche is produced.

摘要： A solid-state charge-coupled-device imager has an imaging region composed of a matrix of vertically and horizontally arrayed photosensitive areas for storing signal charges depending on the intensity of applied light, and a plurality of vertical shift resisters for vertically transferring the signal charges shifted from the photosensitive areas. The signal charges from the vertical shift registers are shifted to a horizontal shift register that transfers the signal charges in a horizontal direction. The horizontal shift register comprises a plurality of charge transfer electrodes horizontally spaced at predetermined intervals. The charge transfer electrodes are inclined to the horizontal direction. The charge transfer electrodes may be inclined linearly in their entirety to the horizontal direction or may be of a chevron shape.

摘要： A solid state image pick-up device includes means for cancelling a difference in impedance between photo-sensing areas in a photo-sensitive array. The impedance difference cancelling means cancels or makes the difference of impedance at each photo-sensing area ignorable to unify the charge handling in respective photo-sensing areas. In practice, the impedance difference cancelling means provides a resistance high enough to make the impedance difference between respective photo-sensing areas ignorable.
