Field of the Invention
The present invention relates to a solid-state imaging device, a driving method thereof, and an imaging system.
Description of the Related Art
FIGS. 1A and 1B include a sectional view of the pixel configuration of a solid-state imaging device, and a view that illustrates a channel potential that shows a state after a reset according to a first embodiment.
FIG. 2 is a view that illustrates a pixel circuit of a solid-state imaging device according to the first embodiment.
FIGS. 3A and 3B include timing charts that illustrate a driving method of the solid-state imaging device according to the first embodiment.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
Preferred embodiments of the present invention will now be described in detail in accordance with the accompanying drawings.
A solid-state imaging device according to a first embodiment of the present invention irradiates a light pulse at an object, and receives a reflection light pulse that is reflected from the object with a plurality of pixel groups. The solid-state imaging device detects a precedent component of a reflection light pulse with a first pixel group synchronously with a timing of turning on the irradiation light pulse, and detects a following component of the reflection light pulse with a second pixel group synchronously with a period of turning off the irradiation light pulse. Detection of this distance information is performed within one frame period.
