Abstract: A portable information handling system integrated organic light emitting diode (OLED) display presents a compensation image having pixels illuminated at predetermined color and luminance settings. The compensation image is captured by a external camera as a calibration image and analyzed to compare pixel color and luminance provided by the OLED display with expected color and luminance to determine pixel compensation values that correct the OLED display for presentation of a uniform visual image that reproduces an intended visual image when the compensation values are applied at presentation of visual images by the OLED display.

Abstract: Methods and apparatuses are provided for synchronizing data by an electronic device. A first operation characteristic of a first image sensor of the electronic device and a second operation characteristic of a second image sensor of the electronic device are identified. At least one of a first access period of a first row of the first image sensor and a second access period of a second row of the second image sensor is changed, based on a difference between the first operation characteristic and the second operation characteristic, to synchronize the first access period and the second access period. The second row corresponds to the first row. Image data corresponding to the first row is acquired through the first image sensor based on the synchronized first access period. Image data corresponding to the second row is acquired through the second image sensor based on the synchronized second access period.
