Detailed description of the invention
Embodiment of the present invention is described below with reference to attached drawing, in which:
Fig. 1 is to be shown according to the shape of the live camera of the adaptive clarity regulating system shown in embodiment of the present invention
It is intended to.
Specific embodiment
The embodiment of adaptive clarity regulating system of the invention is described in detail below with reference to accompanying drawings.
Clarity is essentially different with resolution ratio (further including several words such as resolving power, resolution, resolution), he
Signified particular content it is natively different.Particularly, clarity refers to the readability for the image that human eye is macroscopically observable,
It is subjective sensation of the people caused by the synthesis result of the objective performance as system and equipment to final image.Although subjective sense
Feel, but cannot be measured with an objective standard unlike evaluation of subjective acoustic level, this subjective sensation of clarity is can be into
Row quantitative test, it can it is measured with the thickness of chequered with black and white lines, and has the test method and test chart of standard,
Measurement data has specific unit, i.e. tv line TVL.
And resolution ratio is different from clarity, he does not refer to the subjective sensation of people, and refers to and shooting with video-corder, transmit and showing process
Used in picture quality record index, and display equipment itself have performance the careful degree of image intrinsic screen knot
Structure says the specific scan format for just referring to single image signal and shows the pixel specification of equipment.The scanning lattice of picture signal
Formula shows the pixel specification of equipment, is all expressed with " horizontal pixel × vertical pixel ", unit is not
" line ", but " point ".The resolution ratio of picture signal and the resolution ratio of display equipment are that standard and specification are determined, are to fix not
Become, and clarity is changeable because of condition.The line number of clarity is less than image signal resolution pixel forever and is linked to be
Line number.For example, horizontal pixel is 720 points, that is, available for the scan format of pal television 720 × 576
720 vertical bars, however, with what display high-definition, it is also not possible to which the level for obtaining 720 tv lines is clear
