Apparatus and method for image display and image analysis method

An apparatuses and method for image display and an image analysis method are provided. The image display apparatus includes a storage device, a thermo sensor, a processor, and a display. The storage device stores at least one gain table. Each gain table includes a plurality of gain values. A correspondence relationship is provided between the gain values and a plurality of pixels of an image. The thermo sensor measures an ambient temperature. The processor is coupled to the storage device and the thermo sensor. For each pixel, the processor determines a gain value corresponding to the pixel according to the at least one gain table and the ambient temperature. The processor compensates the image according to the gain values corresponding to the pixels. The display is coupled to the processor and displays the compensated image. The uneven brightness for the display is eliminated or reduced in an image signal processing mode.
