3.10 Field viewing angle
In the camera equipment, taking the lens centre of the camera equipment as the vertex,
the object image of the measured target can pass through the angle formed by the two
edges of the maximum range of the lens.
3.11 Optical axis centre precision
The deviation between the actual imaging centre of the camera equipment and the
theoretical centre of optical imaging.
3.12 Automatic gain control
An automatic control method in which the gain of the amplifying circuit is automatically
adjusted with the signal strength.
3.13 White balance
The image restoration of the photographed object under lighting conditions of different
light sources by the photographic imaging equipment shall have a colour reproduction
consistent with the human eye observing the photographed object under the same
lighting conditions.
3.14 Glare
Visual conditions, due to the unsuitable brightness distribution in the visual field, there
is an extreme brightness contrast in space or time, which causes visual discomfort and
reduce the visibility of objects.
3.15 Colour rendition
The image data describing the colour space coordinates of the scene is mapped to the
image data describing the colour space coordinates of the photo related to the output.
NOTE: Colour rendition usually consists of one or more compensations for the difference
between input and output observation conditions. Therefore, the scale and colour gamut that
describe the colour of the scene shall be mapped to the dynamic range and colour gamut of
the photo, and use preference adjustment. Simply put, it is the ability of the imaging device to
truly reproduce the colour of the subject.
3.16 Ghost
The high-brightness target source existing in the environment quickly reflects inside
the lens, and finally forms an additional image on the image.
Macbeth 24-color test chart shall have no obvious colour difference, and the image
shall have no colour cast. The colour saturation (S) in the grey scale HSV of #21, #22
two blocks (in the middle) of the 24-color test chart shall be less than 15%.
NOTE: Gretag Macbeth colour test chart is the goods name of the test chart provided by Gretag
Macbeth company. This information is given for recommendation to users of this Standard; and
does not mean that the product is approved. For the test chart recommended in the follow-up
