## Abstract

An imaging control device includes: an exposure control portion configured to control an exposure length of an imaging unit, which is capturable an image of a region where an occupant is allowed to occupy in a vehicle cabin, to at least a first exposure period and a second exposure period longer than the first exposure period; an image acquisition portion configured to acquire first captured image data captured in the first exposure period and second captured image data captured in the second exposure period; and a processing unit configured to separately process the first captured image data and the second captured image data.

## Claims

### Claim 1

An imaging control device comprising:
an exposure control portion configured to control an exposure length of an imaging unit, which is capturable an image of a region where an occupant is allowed to occupy in a vehicle cabin, to at least a first exposure period and a second exposure period longer than the first exposure period;
an image acquisition portion configured to acquire first captured image data captured in the first exposure period and second captured image data captured in the second exposure period; and
a processing unit configured to separately process the first captured image data and the second captured image data.

### Claim 2 (depends on 1)

The imaging control device according to claim 1, wherein
the exposure control portion performs control such that the first exposure period and the second exposure period are alternately switched.

### Claim 3 (depends on 1)

The imaging control device according to claim 1, wherein
the exposure control portion corrects a length of the first exposure period at a time of current image-capturing based on an average luminance value of a first region close to the imaging unit in the first captured image data captured in the first exposure period at a time of previous image-capturing, and corrects a length of the second exposure period at the time of current image-capturing based on an average luminance value of a second region farther away from the imaging unit than the first region in the second captured image data captured in the second exposure period at the time of previous image-capturing.

### Claim 4 (depends on 1)

The imaging control device according to claim 1, wherein
the exposure control portion controls a length of an exposure period of an infrared imaging unit that captures an infrared image as the imaging unit.

### Claim 5 (depends on 4)

The imaging control device according to claim 4, wherein
the exposure control portion synchronizes an irradiation period of infrared light with which a region capturable by the infrared imaging unit is irradiated, with the first exposure period and the second exposure period.
