1. A lighting device, comprising:

  • an image display device comprising one or more first light emitters configured to generate and emit light to display an image;

    a general illumination device collocated with the image display device, wherein the general illumination device comprises one or more second light emitters configured to generate and emit light for general illumination,a driver system coupled to the one or more first light emitters of the image, display device and coupled to the one or more second light emitters of the general illumination device,the driver system being configured to control the light generated by the general illumination device; and

    the driver system configured to control the light generated by the image display device;

    a memory;

    a processor having access to the memory and coupled to the driver system to control operation of the driver system; and

    programming in the memory, wherein execution of the programming by the processor configures the lighting device to perform functions including functions to;

    obtain an image selection and a general lighting generation selection as software control data;

    transform the image selection based on a desired color characteristic distribution, wherein the function to transform the image selection comprises functions to;

    calculate a total red content, a total green content and a total blue content of the image selection, wherein;

    the total red content equals a summation of red pixel intensity values within the image selection;

    the total green content equals a summation of green pixel intensity values within the image selection; and

    the total blue content equals a summation of blue pixel values intensity within the image selection;

    select an image transformation function based on a number of illumination requirements, the selected image transformation function includes unknown variables;

    solve, based on the number of illumination requirements, the unknown variables of the selected image transformation function; and

    transform the image selection based on the solved image transformation function to venerate the transformed image selection;

    modify the general lighting generation selection based on the transformed image selection;

    present an image output, based on the transformed image selected, via the image display device; and

    control operation of the general illumination device via the driver system to emit light for general illumination from the general illumination device according to the modified general lighting generation selection.
