ABSTRACT:
A method for compensating an image produced by image means for implementing image information takes account of ambient illumination. Luminance of external background illumination around the image means is measured. The measured luminance of the background illumination is compared with preset tristimulus values and a reflectance factor of the image means, a comparison result is computed, and a control signal is generated to compensate luminance and chroma of an image. Luminance and chroma of the image means are compensated in response to the control signal.
