Content creative intention preservation under various ambient color temperatures
One embodiment provides a method comprising receiving an input content, and receiving ambient contextual data indicative of one or more ambient lighting conditions of an environment including a display device. The input content has corresponding metadata that at least partially represents a creative intent indicative of how the input content is intended to be viewed. The method further comprises adaptively correcting the input content based on the ambient contextual data to preserve the creative intent, and providing the corrected input content to the display device for presentation. The adaptively correcting comprises applying automatic white balancing to the input content to correct color tone of the input content.
1. A method comprising:
receiving an input content, wherein the input content has corresponding metadata that at least partially represents a creative intent indicative of a particular visualization of the input content that a content provider of the input content intends for a viewer to see;
receiving ambient contextual data indicative of one or more ambient lighting conditions of an environment including a display device;
adaptively correcting the input content based on the ambient contextual data to preserve the creative intent, wherein the adaptively correcting comprises applying automatic white balancing to the input content to correct color tone of the input content; and
providing the corrected input content to the display device for presentation.
2. The method of claim 1 , wherein the one or more ambient lighting conditions include at least one of an ambient illuminance of the environment or an ambient color correlated temperature (CCT) of the environment.
3. The method of claim 2 , wherein the automatic white balancing modifies a white point of the input content using a function based on at least one of the ambient illuminance, the ambient CCT, or a pixel value of the input content.
4. The method of claim 2 , wherein the automatic white balancing modifies a white point of the input content using a perceptual color mixing model and a luminance attenuation function that is based on at least one of the ambient illuminance, the ambient CCT, or a neighboring pixel value of the input content.
5. The method of claim 1 , wherein the adaptively correcting further comprises adaptively compensating for a black level of the display device.
6. The method of claim 1 , wherein the adaptively correcting further comprises adaptively correcting saturation and contrast of the input content.
7. The method of claim 1 , wherein the automatic white balancing comprises:
tuning a first parameter and a second parameter of a quadratic mapping function; and
modifying a white point of the input content based on the quadratic mapping function to obtain a compensated white point.
8. The method of claim 1 , wherein the input content includes at least one of an input image or an input video.
9. A system comprising:
at least one processor; and
a non-transitory processor-readable memory device storing instructions that when executed by the at least one processor causes the at least one processor to perform operations including:
receiving an input content, wherein the input content has corresponding metadata that at least partially represents a creative intent indicative of a particular visualization of the input content that a content provider of the input content intends for a viewer to see;
receiving ambient contextual data indicative of one or more ambient lighting conditions of an environment including a display device;
adaptively correcting the input content based on the ambient contextual data to preserve the creative intent, wherein the adaptively correcting comprises applying automatic white balancing to the input content to correct color tone of the input content; and
providing the corrected input content to the display device for presentation.
10. The system of claim 9 , wherein the one or more ambient lighting conditions include at least one of an ambient illuminance of the environment or an ambient color correlated temperature (CCT) of the environment.
11. The system of claim 10 , wherein the automatic white balancing modifies a white point of the input content using a function based on at least one of the ambient illuminance, the ambient CCT, or a pixel value of the input content.
12. The system of claim 10 , wherein the automatic white balancing modifies a white point of the input content using a perceptual color mixing model and a luminance attenuation function that is based on at least one of the ambient illuminance, the ambient CCT, or a neighboring pixel value of the input content.
13. The system of claim 9 , wherein the adaptively correcting further comprises adaptively compensating for a black level of the display device.
14. The system of claim 9 , wherein the adaptively correcting further comprises adaptively correcting saturation and contrast of the input content.
15. A non-transitory processor-readable medium that includes a program that when executed by a processor performs a method comprising:
receiving an input content, wherein the input content has corresponding metadata that at least partially represents a creative intent indicative of a particular visualization of the input content that a content provider of the input content intends for a viewer to see;
receiving ambient contextual data indicative of one or more ambient lighting conditions of an environment including a display device;
adaptively correcting the input content based on the ambient contextual data to preserve the creative intent, wherein the adaptively correcting comprises applying automatic white balancing to the input content to correct color tone of the input content; and
providing the corrected input content to the display device for presentation.
16. The non-transitory processor-readable medium of claim 15 , wherein the one or more ambient lighting conditions include at least one of an ambient illuminance of the environment or an ambient color correlated temperature (CCT) of the environment.
17. The non-transitory processor-readable medium of claim 16 , wherein the automatic white balancing modifies a white point of the input content using a function based on at least one of the ambient illuminance, the ambient CCT, or a pixel value of the input content.
18. The non-transitory processor-readable medium of claim 16 , wherein the automatic white balancing modifies a white point of the input content using a perceptual color mixing model and a luminance attenuation function that is based on at least one of the ambient illuminance, the ambient CCT, or a neighboring pixel value of the input content.
19. The non-transitory processor-readable medium of claim 16 , wherein the adaptively correcting further comprises at least one of adaptively compensating for a black level of the display device.
20. The non-transitory processor-readable medium of claim 16 , wherein the adaptively correcting further comprises adaptively correcting saturation and contrast of the input content.
