Solid state imaging device and method for driving the same

Abstract

In a connection part of vertical transfer registers with respect to a horizontal transfer register, transfer electrodes to which clocks phiV1, phiV2A, phiV3A, phiV2B, phiV3B, and phiV1A are applied are arranged in the cited order. In a horizontal transfer register 6, transfer is conducted by 3-phase clocks phiH1A, OH1B, and phiH2. By activating clocks, signal charges of a channel denoted by A-A' and channels equivalent thereto are first transferred to undersides of electrodes of phiH1A of the horizontal transfer register. The signal charges are transferred in the rightward direction to underside of electrodes of phiH1B. Subsequently, signal charges of a channel denoted by B-B' and channels equivalent thereto are transferred to undersides of electrodes of phiH1B of the horizontal transfer register, and mixed with the signal charges previously transferred. As a result, it becomes possible to reduce pixels and lower the resolution without conducting high speed driving.

Description

technical field [0001] The present invention relates to a solid-state imaging device of the type capable of simultaneously reading all pixels, wherein the signal charge of each unit pixel can be simultaneously and independently read into a vertical transfer register, and the present invention also relates to driving such A method for solid-state imaging devices. More particularly, the present invention relates to a solid-state imaging device constructed so that signal charges aligned in the horizontal direction are reduced, and to a method of driving the solid-state imaging device. Background technique [0002] In recent years, there has been a demand for better display of moving images on monitors of personal computers. However, with current processing capabilities, it is difficult to display moving images on a personal computer at a resolution close to that of a television. In order to display image data taken from eg a CCD (Charge Coupled Device) camera, it is necessary...

Problems solved by technology

Therefore, when the processing speed of the device cannot adapt, the frame rate cannot be maintained accordingly, thus creating a defect

[0011] In addition, in the case of reducing the resolution in the device itself, the 1 / 2 image data to be erased must be transmitted in a high-speed drive mode.

Therefore, the device requires redundant performance, which reduces the production efficiency

In addition, the energy consumption of the drive circuit increases, and there is a disadvantage of performance degradation from the perspective of equipment.
