1. An image processing device comprising:
- an imaging unit that picks up an image;
an image density recognizer that recognizes density of the image; and
an exposure controller that in an exposure control period automatically controls an exposure of the imaging unit based on the density recognized, wherein the exposure control period includes at least a maximum exposure period during which the exposure is set to a maximum exposure, a minimum exposure period during which the exposure is set to a minimum exposure, and a normal exposure period during which the exposure is set to in between the maximum exposure and the minimum exposure; and
a problem recognizer that determines any one of whether the imaging unit is abnormal and whether environment is unsuitable for picking up an image by the imaging unit based on densities of images, which are recognized by the image density recognizer, that are picked up during the maximum exposure period, the minimum exposure period, and/or the normal exposure period.

Abstract
An image processing device includes a camera that picks up an image, an image density recognizer that recognizes density of the image, and an exposure controller that in an exposure control period automatically controls an exposure of the camera based on the density recognized. The exposure controller period includes at least a maximum exposure period during which the exposure is set to a maximum exposure, a minimum exposure period during which the exposure is set to a minimum exposure, and a normal exposure period during which the exposure is set to in between the maximum exposure and the minimum exposure.

14. An image processing device comprising:
-
an image obtaining unit that any one of includes an imaging unit that picks up an image of a surrounding of a vehicle and from an external device receives an image of a surrounding of a vehicle picked up by an imaging unit;
an exposure controller that during an exposure control period automatically controls an exposure of the imaging unit based on a density distribution of an image obtained by the image obtaining unit, wherein the exposure automatic control period includes at least a maximum exposure period during which the exposure is set to a maximum exposure, a minimum exposure period during which the exposure is set to a minimum exposure, and a normal exposure period during which the exposure is set to in between the maximum exposure and the minimum exposure; and
a determining unit that determines at least one of whether the imaging unit is abnormal and whether environment is unsuitable for picking up an image by the imaging unit, based on densities of images that are picked up during the maximum exposure period, the minimum exposure period, and the normal exposure period. - View Dependent Claims (15, 16, 17)

18. An operation supporting device comprising:
-
an image information obtaining unit that obtains image information that has been processed by an image processing device;
a supporting unit that supports running of a vehicle by any one of controlling operation of a vehicle using at least the image information and providing information to a driver; and
a support operation changer that switches operation of the supporting unit upon receiving a notification that an abnormality has occurred in an imaging unit of the image processing device. - View Dependent Claims (19, 20, 21, 22, 23)

24. An operation supporting system comprising:
-
an image obtaining unit that obtains an image picked up by an imaging unit;
an exposure controller that in an exposure control period automatically controls an exposure of the imaging unit based on a density distribution of an image obtained by the image obtaining unit, wherein the exposure control period includes at least a maximum exposure period during which the exposure is set to a maximum exposure, a minimum exposure period during which the exposure is set to a minimum exposure, and a normal exposure period during which the exposure is set to in between the maximum exposure and the minimum exposure;
a determining unit that determines any one of whether the imaging unit is abnormal and whether environment is unsuitable for picking up an image by the imaging unit based on densities of images that are picked up during the maximum exposure period, the minimum exposure period, and/or the normal exposure period; and
a supporting unit that controls operation of a vehicle using at least the image or provides information to a driver, thereby supporting running of a vehicle.
