Title
Image Quality Of Digital Photography Prints - 2: Dependence Of Print Quality On Pixel Number Of Input Camera
Abstract
In the digital photography, the input photo-image is sampled by segmental imager and then converted into the electronic signal. The divided unit of imager is called a pixel and the segmentation fixes the size and number of pixels. The definition of output pictures is directly related to the pixel number of the input imager. Thus it is a key function for image quality of the output picture in digital photography.This paper discussed the relation between pixel numbers of imager in the input digital cameras and image quality of output prints. The sample prints showing the same pattern images in the different definition proportional to the pixel numbers of imager were produced by digital photography system. The image quality of those sample prints were evaluated by subjective human viewings and objective image structural analyses.The correlation between pixel numbers consisting of prints and their structural image quality was distinctive on the subjective visual and the objective physical evaluations. The results suggested that the optimum pixel numbers of imager in digital cameras to produce hand-held size digital photography color prints.
