Provided is a correction method performed in a display device including a matrix of pixels each including an organic EL element that emits light in accordance with a luminance signal. The method includes: obtaining, in advance, first correction data for correcting the luminance signal; transforming the first correction data into second correction data smaller in data size than the first correction data; and correcting the luminance signal using the second correction data. The first and second correction data respectively include first color correction data for correcting first sub pixel luminance, second color correction data for correcting second sub pixel luminance, and third color correction data for correcting third sub pixel luminance. In the transforming, the first correction data is transformed such that a data reduction amount of the second color correction data is greater than a data reduction amount of the first color correction data.

The color unevenness correction device specifies a correction amount based on a first write signal for a first color picture element composing the one pixel and a second write signal for a second color picture element other than the first color picture element composing the pixel and corrects the second write signal in accordance with the correction amount.

Systems and methods for driving an electrowetting display device including a plurality of sub-pixels are presented. A reflectance level of a first sub-pixel in the plurality of sub-pixels is set to a minimum reflectance level or a threshold reflectance level. A reflectance quantization error is determined and a second reflectance level of a second sub-pixel in the plurality of sub-pixels is set to a second target reflectance level of the second sub-pixel plus a first fraction of the reflectance quantization error. A third reflectance level of a third sub-pixel in the plurality of sub-pixels is set to a third target reflectance level of the third sub-pixel plus a second fraction of the reflectance quantization error, and a fourth reflectance level of a fourth sub-pixel in the plurality of sub-pixels is set to a fourth target reflectance level of the fourth sub-pixel plus a third fraction of the reflectance quantization error.

A machine-implemented method includes obtaining input data and generating output data. The status of at least one contextual factor is determined and compared with a standard. If the status meets the standard, a transformation is applied to the output data. The output data is then outputted to the viewer. Through design and/or selection of contextual factors, standards, and transformations, output data may be selectively outputted to viewers in a context-suitable fashion, e.g. on a head mounted display the viewer's central vision may be left unobstructed while the viewer walks, drives, etc. An apparatus includes at least one sensor that senses a contextual factor. A processor determines the status of the contextual factor, determines if the status meets a standard, generates output data, and applies a transformation to the output data if the status meets the standard. A display outputs the output data to the viewer.
