Abstract

The present application relates to an image processing device, an image processing system and an image processing method. Specifically, the image processing apparatus includes an illumination light intensity calculation unit that determines an illumination light intensity image using at least one smoothed image from lightness values ​​based on pixel values ​​of individual pixels forming the original image, wherein the at least one smoothed an illuminance image having lightness values ​​smoothed using at least one smoothness, the illumination light intensity image having illumination light components of the original image as pixel values; and a light source color calculation unit that determines from the original image and the illumination light intensity image The color of the lighting source, used as the color of the light source of the lighting light.

Description

technical field [0001] The present invention relates to an image processing device, an image processing system and an image processing method. Background technique [0002] Nowadays, due to the widespread use of devices such as digital cameras, smart phones, or tablet computers, more users shoot and view digital images. As opportunities to capture images increase, shooting environments also diversify. As a technique for adjusting the hue of images photographed under environments of various lighting conditions, an automatic white balance technique is available. Auto white balance technology sets the color of the light source in the image to be close to white light. In the related art, the feature of pixel value is usually used to adjust the color shade. [0003] Images captured by a digital camera are sometimes different from the scene seen by a human, especially if the difference between dark and bright parts of an object is large (for example, if the shooting operation i...
