TECHNICAL FIELD

The present disclosure relates to an imaging device that images a subject.

BACKGROUND ART

In an imaging device, for example, a plurality of pixels is coupled to an AD (Analog to Digital) converter via one signal line. For example, PTL 1 discloses an imaging device including a plurality of signal lines. The plurality of these signal lines is short-circuited to increase the image quality of captured images.

SUMMARY OF THE INVENTION

In this way, imaging devices are required to offer captured images having high image quality and expected to have image quality further increased.

It is desirable to provide an imaging device that makes it possible to increase the image quality of a captured image.

An imaging device according to an embodiment of the present disclosure includes an imaging unit, a connector, and a converter. The imaging unit includes a first signal line, a first pixel, a second signal line, and a second pixel. The first pixel is configured to output a first pixel voltage to the first signal line. The first pixel voltage corresponds to an amount of received light. The second pixel is configured to output a second pixel voltage to the second signal line. The second pixel voltage corresponds to the amount of received light. The connector includes a connection line, a first connection switch, a first control circuit, a second connection switch, and a second control circuit. The first connection switch is configured to couple the first signal line to the connection line by being turned on. The first control circuit is configured to control an operation of the first connection switch on the basis of a voltage in the first signal line. The second connection switch is configured to couple the second signal line to the connection line by being turned on. The second control circuit is configured to control an operation of the second connection switch on the basis of a voltage in the second signal line. The converter is coupled to the first signal line and the second signal line and configured to perform the AD conversion on the basis of each of the first pixel voltage and the second pixel voltage.

In the imaging device according to the embodiment of the present disclosure, the first pixel outputs the first pixel voltage to the first signal line and the second pixel outputs the second pixel voltage to the second signal line. The AD conversion is then performed on the basis of each of the first pixel voltage and the second pixel voltage. The operation of the first connection switch is controlled on the basis of the voltage in the first signal line. The operation of the second connection switch is controlled on the basis of the voltage in the second signal line. The first connection switch is configured to couple the first signal line to the connection line by being turned on. The second connection switch is configured to couple the second signal line to the connection line by being turned on.

The imaging device according to the embodiment of the present disclosure controls the operation of the first connection switch on the basis of the voltage in the first signal line and controls the operation of the second connection switch on the basis of the voltage in the second signal line. This makes it possible to increase the image quality of a captured image. It is to be noted that the effects described here are not necessarily limited, but any of effects described in the present disclosure may be included.
