  • Publication number: 20060203113
    Abstract: When pixels are simply skipped while keeping both an order of pixel information and a spatial positional relation the same as those in all-pixel readout, since a distance between pixels to be read out increases, the Nyquist frequency decreases and aliasing noise increases. A 5×5 pixel block is set as a unit pixel block and pieces of pixel information in first, third, and fifth columns of first, third, and fifth rows of a pixel arrangement are added and outputted as an output in an ath row and an ath column of the unit pixel block. Then, pieces of pixel information in sixth, eighth, and tenth columns of the first, the third, and the fifth rows of the pixel arrangement are added and outputted as an output in the ath row and a bth column of the unit pixel block. Subsequently, pieces of pixel information are added and outputted up to a last column or a column near the last column.

  • Publication number: 20060164527
    Abstract: When pixel signals are separately read from a plurality of horizontal signal lines to achieve high-speed processing, color difference in image signals and stripes are eliminated. In the operation of reading the pixel signals from the (2n)th row, the pixel signals from R pixels on odd columns are output to an output system A through a horizontal signal line (60A). On the other hand, the pixel signals from Gr pixels on even columns are output to an output system B through a horizontal signal line (60B). In the operation of reading the pixel signals from the (2n+1)th row, the pixel signals from Gb pixels on the odd columns are output to the output system B through the horizontal signal line (60B) by the switching operation in a switching circuit (50). Similarly, the pixel signals from B pixels on the even columns are output to the output system A through the horizontal signal line (60A) by the switching operation in the switching circuit (50).

  • Publication number: 20060001751
    Abstract: A solid-state imaging device is capable of simplifying the pixel structure to reduce the pixel size and capable of suppressing the variation in the characteristics between the pixels when a plurality of output systems is provided. A unit cell (30) includes two pixels (31) and (32). Upper and lower photoelectric converters (33) and (34), transfer transistors (35) and (36) connected to the upper and lower photoelectric converters, respectively, a reset transistor (37), and an amplifying transistor (38) form the two pixels (31) and (32). A full-face signal line 39 is connected to the respective drains of the reset transistor (37) and the amplifying transistor (38). Controlling the full-face signal line (39), along with transfer signal lines (42) and (43) and a reset signal line (41), to read out signals realizes the simplification of the wiring in the pixel, the reduction of the pixel size, and so on.

  • Publication number: 20030227039
    Abstract: A photodiode and a FD portion are arranged in parallel with a transfer gate portion interposed therebetween, and a transfer electrode is arranged above the transfer gate portion. The transfer electrode has a body portion and an expanded portion and is expanded in the gate lengthwise direction. Where the partial expanded portion is provided on the transfer electrode in this manner, the modulation degree of the transfer electrode can be increased while the amount of reduction of the area of a light reception portion of the photodiode is reduced (the numerical aperture is increased). As a result, a solid-state image pickup device with which transfer residual is less likely to occur and which is suitable for complete transfer can be configured.
