Problems solved by technology

However, a high-capacitance FD reduces the gain at the time of converting charge into a voltage using the FD, and noise is also amplified when the image signal is amplified in a circuit in a subsequent stage, thus causing a deterioration in the S / N of the image signal. deterioration

Embodiment Construction

[0029] Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

[0030] figure 1 is a block diagram showing a structural example of an embodiment of a solid-state imaging device to which the present invention is applied.

[0031] figure 1 The illustrated solid-state imaging device 11 includes a pixel unit 12 , a vertical drive circuit 13 , a column processing circuit 14 , an output circuit 15 and a control circuit 16 .

[0032] The pixel unit 12 has a plurality of pixels arranged in a matrix (for example figure 2 Pixel 21 which will be explained later). These pixels each output a reset level signal and a level signal corresponding to the amount of incident light.

[0033] The vertical driving circuit 13 outputs driving signals (such as a selection signal Sel, a reset signal Rst, a transfer signal Trf, and a connection signal Cnt) to scan each pixel row included in the pixel unit 12 , thereby d...

Abstract

The present invention relates to an imaging device, an imaging method, and electronic equipment. The imaging device includes a pixel unit including pixels arranged in a plane, and a driving unit. The pixel includes: an accumulating section for detecting a physical quantity and accumulating charges corresponding to the physical quantity; a transferring section for transferring the charges from the accumulating section; a converting section for converting the charges into a voltage; an output unit that outputs a signal of the voltage converted by the conversion unit; a reset unit that resets the potential of the conversion unit; and a connection unit connected to the conversion unit. The drive unit is used to output a transfer signal and a connection signal, the transfer signal gives an instruction to transfer the charge, and the connection signal controls the connection and non-connection between the conversion parts. The drive unit transfers the electric charge in a state where the conversion parts are connected to each other. The present invention can obtain signals with excellent S / N and wide dynamic range.

Description

[0001] Cross References to Related Applications [0002] This application contains subject matter related to that disclosed in Japanese Priority Patent Application JP2011-188993 filed in Japan Patent Office on Aug. 31, 2011, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to an imaging device, an imaging method and electronic equipment, and in particular to an imaging device, an imaging method and an electronic equipment capable of obtaining a signal with an excellent signal-to-noise ratio (S / N) and a wide dynamic range. Background technique [0004] In the related art, a photodiode (PD) of each pixel in a solid-state imaging device such as a charge coupled device (Charge Coupled Device; CCD) or a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor; CMOS) sensor receives incoming light to generate charge. Many solid-state imaging devices are configured such that charges of t...
