State determines that component (200) is determined using the image for the film (10) for measuring component (100) shooting from state
The location status of film (10).
Fig. 4 illustrates that the image to the film measured in the device for being used to handle film according to embodiment is handled
Processing procedure.Fig. 5 illustrates the area size of the defect area of the film measured in the device for being used to handle film according to embodiment.
In embodiments, referring to Fig. 4 and Fig. 5, state determines that component (200) can be based on measuring component by state
(100) whether the gray value of the location drawing picture of the film (10) measured is in thin to determine within the scope of reference gray level (gray) value
The location status of film (10).The identified state history of film (10) can be stored in storage member, or may be output to defeated
Component (90) out.
Referring to Fig. 4, state determines that component (200) can will measure the 8 bit analogy images that component (100) is measured from state
Multiple regions are divided into, and gray scale (gray) the value numerical digit in each region can be turned to the number between 0 and 255.State
Determine whether component (200) can be within the scope of reference gray level value the defect for determining each region based on the grayscale through digitisation
Presence.Reference gray level value range can be predefined based on historical record is measured, or may be configured as measuring component from state
(100) average value measured.
When some region of gray value exceeds predetermined reference gray level value range, the region can be considered as defect
Region.It can be based on the area size of defect area (S), length of the width of defect area (S), defect area (S) etc. and to thin
The state of film (10) is classified.
It, can be based on the width (w) and length (l) for being considered as detected region (area) and by defect area referring to Fig. 5
(S) area size is defined as area size=(w+l)/2.

The breadth length ratio as directionality of the defect area measured in device for handling film.
The out-of-roundness of defect area (S) can also be passed through in addition to the area size of defect area (S) referring to Fig. 6 to Fig. 8
Value and classify to the location status of film (10).For example, for the low non-round angle value of defect area (S), such as zero (0),
Defect area (S) can be considered as existing defects due to scratch.
In addition, the breadth length ratio (referring to Fig. 8) and gray scale of the slope (referring to Fig. 7) of defect area (S), defect area (S)
Value difference can also be considered as the reference of classification film (10), to determine the location status of film (10).
In embodiments, status display component (300) can determine film determined by component (200) according to as state
(10) location status shows label (70) on the corresponding position of film (10).
Status display component (300) according to the location status of film (10) by showing and the location status pair of film (10)
The label (70) answered, user can detect the location status of film (10) easily.
In embodiments, status display component (300) may include display member (310).Display member (310) can pass through
The location status of film (10) is shown to film (10) jet ink.For example, display member (310) can be along film (10)
Width direction alignment.Therefore, can pass through in the case where not shifting display member (310) along the width direction of film (10)
Display member (310) corresponding position operation and label (70) are shown on corresponding position.
(70) can be marked according to the state of film (10) and with different length, region, size etc. to show, so that operation
Person can identify the state of film (10) after forming label (70).
In embodiments, label (70) can be formed by spraying multiple ink-jet points (71), and the number of ink-jet point (71)

It, can be based on the identified film in the state (S200) for determining film in the state (S300) of display film
(10) location status and in the label (70) for showing the location status according to film (10) on film (10).In display film
When state (S300), it can be shown on the corresponding position of film (10) according to the label (70) of the location status of film (10) with aobvious
Show the state of film (10).
The method (S1) of processing film can further include detection label (S400).In detection label (S400), can have certainly
The film (10) of label (70) detects label (70) and may recognize that the state of film (10), this permits a determination that film
(10) future with or without the use of.
In the device (1) according to the embodiment for being used to handle film and the method (S1) for handling film, it can measure thin
The location status of film (10), and the label (70) according to the state measured can be shown on corresponding position.It therefore, can be easily
Detect the state of film (10).
Be disclosed herein various exemplary embodiments, and although using specific term, these terms be only used for and
It is interpreted ordinary meaning and illustrative meaning, and not to limit purpose.In some cases, unless in addition clearly referring to
It is bright, otherwise as in technique there is technical staff to understand before present application is filed an application, in conjunction with a specific embodiment
