IMAGE PROCESSING APPARATUS, IMAGING APPARATUS, AND DETERMINATION METHOD
First Claim
1. An image processing apparatus comprising:
- an evaluation value calculation unit configured to calculate a contrast evaluation value of each of first image data and second image data in which an object is imaged in a state in which auxiliary light is emitted to the object included in a first image corresponding to the first image data;
a determination unit configured to determine that fog or haze is occurring at a time the contrast evaluation value of the first image data, which has been calculated by the evaluation value calculation unit, is equal to or greater than the contrast evaluation value of the second image data; and
an image processing unit configured to perform image processing to the first image data or the second image data based on a determination result of the determination unit.

Abstract
An image processing apparatus includes: an evaluation value calculation unit configured to calculate a contrast evaluation value of each of first image data and second image data in which an object is imaged in a state in which auxiliary light is emitted to the object included in a first image corresponding to the first image data; a determination unit configured to determine that fog or haze is occurring at a time the contrast evaluation value of the first image data, which has been calculated by the evaluation value calculation unit, is equal to or greater than the contrast evaluation value of the second image data; and an image processing unit configured to perform image processing to the first image data or the second image data based on a determination result of the determination unit.

3. An imaging apparatus comprising:
-
an imaging unit configured to generate image data of an object by imaging the object; an auxiliary light emitting unit configured to emit auxiliary light to the object; an evaluation value calculation unit configured to calculate a contrast evaluation value of each of first image data generated by the imaging unit and second image data generated by the imaging unit in a state in which the auxiliary light emitting unit emits auxiliary light to the object; a determination unit configured to determine that fog or haze is occurring at a time the contrast evaluation value of the first image data, which has been calculated by the evaluation value calculation unit, is equal to or greater than the contrast evaluation value of the second image data; and a light emission controller configured to output an inhibition signal for inhibiting auxiliary light emission to the auxiliary light emitting unit at a time the determination unit determines that the fog or haze is occurring. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)

11. A determination method performed by an image processing apparatus, comprising:
-
calculating a contrast evaluation value of each of first image data and second image data in which an object is imaged in a state in which auxiliary light is emitted to the object included in a first image corresponding to the first image data; determining that fog or haze is occurring at a time a contrast evaluation value of the first image data is equal to or greater than a contrast evaluation value of the second image data; and performing image processing with respect to the first image data or the second image data based on a determination result of the determination unit.
