摘要： A processing device includes generation circuitry, storage circuitry, and interpolation circuitry. The generation circuitry generates a first index based on a numerical value of a high-order predetermined number of digits. The converted value of the reference input value corresponding to each index obtained in the generation circuitry is beforehand stored as a look-up table in the storage circuitry. The interpolation circuitry acquires the first converted value corresponding to the first index using the look-up table. And the interpolation circuitry computes the second index that adjoins the first index by carrying out increment or decrement of the first index. Furthermore, the interpolation circuitry acquires the second converted value corresponding to the second index using the look-up table of the storage circuitry. And the interpolation circuitry computes the converted value of the input value by linearity interpolation based on the shift amount from the reference input value of the first index.

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.
