A11. FOCUS RANGE
The minimum/maximum focus distance is the minimum/maximum projection distance (The
distance between the outermost element of projection lens and screen), expressed in meter, at which
the image is still at its acceptable focus level.(acceptable focus level is specified by FOCUS LIMIT
SAMPLE approved by customer)
A12. COLOR
Color is expressed as (x, y) in 1931CIE chromaticity values
Note: Color is measured at the center of the screen that is entirely the measured color under default
brightness and contrast settings
A13. ANSI COLOR
ANSI Color is expressed as (u, v) in 1976 CIE chromaticity values
Note: Color is measured at the center of the screen that is entirely the measured color under default
brightness and contrast settings.
A14. COLOR UNIFORMITY
Color Uniformity is the maximum color difference (
△
x,
△
y) between any two points out of L1~L13
A15. ANSI COLOR UNIFORMITY
ANSI Color Uniformity:
△
u’v’= [(u’1-u’0)^2+(v’1-v’0)^2]^1/2
(u’0,v’0): the average color of L1~L13
(u’1,v’1): the spot with maximum deviation from (u’0,v’0)
A16. PROJECTION OFFSET
Projection Offset= Center of image above projection lens optical axis / Half image height x 100%
Note: Optical engine should be kept horizontal attitude
A17. Defocus and Flare Test Procedure
Procedure:
Step 1: Get best focus at Screen Center with Pattern1
Step 2: Check specified screen sizes and zoom positions
Step 3: Use Chart1 to measure Defocus and Flare for whole screen of R,G,B color at Pattern 2,3,4 and
record the maximum number
Example of 1.5 pixel flare:
