| 发明名称 | Haze image discriminating apparatus and discriminating method | ||
| 摘要 | A haze image discriminating apparatus has a first calculator to calculate a difference between a color difference component of an image signal of each of a plurality of pixels in an image and a gray value, and calculate a first ratio of pixels in which the difference is lower than a first reference value, to the plurality of pixels, a second calculator to calculate a second ratio of pixels in which a luminance component of the pixel signal of each of the plurality of pixels is lower than a second reference value, to the plurality of pixels, and a haze-degree determining unit to determine that a degree of haze of the image is higher as the first ratio is higher and the second ratio is lower. | ||

| 主权项 | 1. A haze image discriminating apparatus comprising: a first calculator configured to calculate a difference between a color difference component of an image signal of each of a plurality of pixels included in an image and a gray value, and calculate a first ratio of pixels in which the difference is lower than a first reference value, to the plurality of pixels; a second calculator configured to calculate a second ratio of pixels in which a luminance component of the pixel signal of each of the plurality of pixels is lower than a second reference value, to the plurality of pixels; and a haze-degree determining unit configured to determine that a degree of haze of the image becomes higher as the first ratio is higher and the second ratio is lower. | ||
