IMAGE DISPLAY METHOD AND ELECTRONIC DEVICE

摘要

An image display method, adapted to an electronic device having a screen, an image capturing unit, and a light sensor, includes the following steps. A preview image captured by the image capturing unit is received and processed so as to generate a plurality of pixel luminance values of the preview image. A light illumination of an ambient light detected by the light sensor is received. An output Gamma lookup table among a plurality of Gamma lookup table is selected according to the pixel luminance values and the light illumination of the ambient light. An adjusted pixel luminance value corresponding to each of the pixel luminance values is generated based on the output Gamma lookup table so as to accordingly display the preview image on the screen with sunlight readability. An electronic device is further provided in the invention to implement the above method.
