An image processing apparatus includes: a dividing processing circuit configured to divide an imaging signal that is obtained by capturing an image of inside of a subject into a first base component and a detail component, the first base component corresponding to an illumination component of an object, the detail component corresponding to a reflectance component of the object; a color enhancement processing circuit configured to generate a second base component by performing a color enhancement process on the first base component, the color enhancement process being a process of increasing color gradation of a mucosa color in a predetermined color space; and a synthesizing circuit configured to synthesize the second base component and the detail component to output a synthesized signal.

Video presence systems are described that detect an area of interest (e.g., facial region) within captured image data and analyze the area of interest using known color information of the content currently being presented by a display, along with measured ambient light color information from a color sensor, to determine whether the area of interest (e.g., face) is currently illuminated by the display or whether the AOI is not affected by the display and instead only illuminated by the ambient light. Upon determining that the display casts color shade on the AOI, the video presence system pre-processes the image data of the detected area of interest to correct the color back to skin color under ambient light prior to performing general white balance correction.

A processing system adjusts a saturation component of a hue-saturation-value (HSV) color space pixel input for an organic light emitting diode (OLED) display panel as a function of the hue component. The processing system converts components of a pixel input from a non-HSV color space to HSV components of the pixel input in HSV color space and modifies the saturation component of the pixel input in HSV color space based on the hue component of the pixel input to generate modified HSV components of the pixel input. The processing system then converts the modified HSV components of the pixel input back into the original color space to produce modified components of the pixel input in the original color space and provides the modified components of the pixel input for receipt by the OLED display, allowing the pixel to be driven at a lower pixel value while maintaining perceptual quality.
