A wavelength detecting apparatus capable of detecting the main wavelength of the light coming into an image capture apparatus and a focus detecting apparatus using the same are disclosed. The wavelength detecting apparatus may include a spectral unit which separates the incoming light according to the respective wavelengths, and may focus the separated light onto a sensor. The main wavelength can be determined based on the wavelength distribution sensed by the sensor. The determined wavelength can be used to further determine amount of adjustment to be made to the defocus amount to compensate for the chromatic aberration associated with the wavelength of the light illuminating the source.

The present invention relates to a gamma data generation method of a display device. In the method, gamma data including red gamma data, green gamma data, and blue gamma data is determined. A target luminance and a target color coordinate of a first reference gray are determined. Then, an image is displayed on a display device based on red, green, and blue input image signals for a first reference gray, and a first luminance and a first color coordinate from the image are measured. Then, it is determined whether a coordinate difference between the first color coordinate and the target color coordinate and a luminance difference between the first luminance and the target luminance are in an allowable error range or not. The first luminance and the first color coordinate are converted to a first coordinate of a CIE XYZ coordinate system, and the target luminance and the target color coordinate are converted to a target coordinate of the CIE XYZ coordinate system if the coordinate difference and the luminance difference are not in the allowable error range. Finally, the red gamma data, the green gamma data, or the blue gamma data is corrected so that a red luminance, a green luminance, or a blue luminance of the image is changed according to a comparison of the first coordinate of the CIE XYZ coordinate system with the target coordinate of the CIE XYZ coordinate system.
