Abstract
A method for estimating image conversion parameters is revealed. Firstly, using an image capturing unit to capture at least one captured image of an object to an image processing unit for calculation. The image processing unit can take linear brightness change of single captured image to estimate the image conversion parameters, also can take comparison of linear and non-linear images to estimate the image conversion parameters, further can take the difference of exposure quantities to estimate the image conversion parameters. Therefore, the estimation of the image conversion parameters can be finished well and easily.
