Abstract:
1. An image pickup device for shooting a scene, comprising: an image-pickup module, arranged for capturing a plurality of temporary images of the scene; an image-synthesis module, arranged for extracting a part of each of the temporary images, combining the parts of the temporary images to form a panorama temporary image, and splitting the panorama temporary image into a plurality of zone-areas according to at least one threshold value and a panorama luminosity histogram of the panorama temporary image; a database, arranged for storing a lookup table that records a plurality of exposure values, and the plurality of exposure values corresponding to a luminance value of each the zone-area respectively; and a processing module, arranged for obtaining the plurality of exposure values corresponding to the luminance values respectively from the database, obtaining a weighting-exposure value by an equation, and controlling the image-pickup module to perform a panorama image capturing process according to the weighting-exposure value; wherein, the equation is to multiply each of the exposure values by a ratio of the zone-area corresponding to each of the luminance values to the total area and then sum up the products to generate the weighting-exposure value.
