Drawings
Embodiments of the invention will now be described with reference to the accompanying drawings, in which:
fig. 1 is a schematic external view of a field camera of an adaptive sharpness adjustment system according to an embodiment of the present invention.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The definition and the resolution (including several words such as resolution, etc.) are different in nature, and the specific content referred to by them is not the same. In particular, sharpness refers to the degree of sharpness of an image viewed macroscopically by the human eye, and is the subjective perception of the final image by people resulting from the combined results of objective performance of the system and the device. Although subjective, unlike subjective listening evaluations, which cannot be measured by an objective standard, the subjective perception of intelligibility is quantifiably measurable in terms of the thickness of the lines between black and white, and standard test methods and patterns, the measurement data of which has a definite unit, i.e., the tv line TVL.
The resolution and the definition are different, and the resolution and the definition do not refer to the subjective feeling of people, but refer to image quality recording indexes used in the processes of recording, transmitting and displaying, and an inherent screen structure of the display device for expressing the image fineness, namely, the specific point refers to the scanning format of a single image signal and the pixel specification of the display device. The scanning format of the image signal and the pixel specification of the display device are both expressed by "horizontal pixel × vertical pixel", and the unit thereof is not "line" but "dot". The resolution of the image signal and the resolution of the display device are system and specification determined, and are fixed, and the definition is changeable depending on the conditions. The number of lines of definition is always smaller than the number of lines connected by pixels of resolution of image signals. For example, for the 720 × 576 scan format of the PAL tv, the horizontal pixels are 720 dots, that is, 720 vertical lines can be obtained, but no matter what high-definition display is used, the horizontal definition of 720 tv lines cannot be obtained.
