Image processing apparatus and image processing method for processing a flesh-colored area
View Patent ↗According to one embodiment, an image processing apparatus includes a detection module configured to detect a specific color area included in image data, an image processing control module configured to generate an image processing control signal for controlling an image process for the specific color area among image processes including a sharpening process for the image data, and an image processing module configured to subject the image data to the image process on the basis of the image processing control signal.
1. An image processing apparatus comprising:
a detector or detection unit configured to detect a flesh-colored area included in first image data;
an image processing controller or an image processing control unit configured to generate an image processing control signal for controlling an image process for the flesh-colored area among image processes including a sharpening process for the first image data; and
an image processor or an image processing unit configured to subject the first image data to the image process on the basis of the image processing control signal,
wherein the sharpening process includes a super-resolution process of creating second image data of a second resolution higher than a first resolution from the first image data of the first resolution, and a sharpness process of emphasizing an edge of an image included in the second image data, and
the image processing controller or the image processing control unit is configured to generate the image processing control signal for setting levels of the super-resolution process and the sharpness process for the flesh-colored area and levels of the super-resolution process and the sharpness process for an area excluding the flesh-colored area at different levels.
2. The image processing apparatus of claim 1 , wherein the image processing controller or the image processing control unit is configured to set a gain of the sharpening process including the super-resolution process for the flesh-colored area lower than a gain of the sharpening process including the super-resolution process for the area excluding the flesh-colored area.
3. The image processing apparatus of claim 1 , wherein the image processing controller or the image processing control unit is configured to generate the image processing control signal for setting a second level of the super-resolution process for the flesh-colored area to be lower than a first level, and setting the first level of the super-resolution process for the area excluding the flesh-colored area.
4. The image processing apparatus of claim 3 , wherein the image processing controller or the image processing control unit is configured to set a gain of the sharpening process including the super-resolution process for the flesh-colored area lower than a gain of the sharpening process including the super-resolution process for the area excluding the flesh-colored area.
5. The image processing apparatus of claim 1 , wherein the image processing controller or the image processing control unit is configured to generate the image processing control signal for setting a second level of the sharpness process for the flesh-colored area to be lower than a first level, and setting the first level of the sharpness process for the area excluding the flesh-colored area.
6. An image processing method for detecting a flesh-colored area included in first image data, generating an image processing control signal for controlling an image process for the flesh-colored area among image processes including a sharpening process for the first image data, and subjecting the first image data to the image process on the basis of the image processing control signal, and the sharpening process including a super-resolution process of creating second image data of a second resolution higher than a first resolution from the first image data of the first resolution, and a sharpness process of emphasizing an edge of an image included in the second image data, the method comprising:
generating the image processing control signal for setting levels of the super-resolution process and the sharpness process for the flesh-colored area and levels of the super-resolution process and the sharpness process for an area excluding the flesh-colored area at different levels.
7. The image processing method of claim 6 , wherein further comprising setting a gain of the sharpening process including the super-resolution process for the flesh-colored area to be lower than a gain of the sharpening process including the super-resolution process for the area excluding the flesh-colored area.
