Abstract: A method for previewing an image in a camera prior to output. The method includes steps of gathering image data, storing the image data, calculating display parameters using the stored image data, storing the display parameters in a look-up table; and applying the display parameters in the look-up table to at least a portion of the image data to produce preview image data. The display parameters can be quickly calculated using a digital signal processor to achieve real-time image previewing. The parameters used in an embodiment camera are vertical down sampling (51) white balance and gain control (52), horizontal up/down sampling (53), and color space conversion and gamma correction (55). The resulting preview processed image may be stored in memory via an interface (56) and viewed via a preview display. Once calculated using a preview algorithm run on a digital signal processor, these parameters can be combined in one or more look-up tables that can be updated by the digital signal processor as imaging conditions demand.
