Abstract

PURPOSE:To stably and easily specify an area for masking trimming without requiring any extra parts by changing the specified area in the order of the entirety (initial), an A3 area, a center part, a right upper part,... and the entirety every time a specific key is pressed. CONSTITUTION:A projection screen 1, an LCD display panel 2 which displays an image corresponding to marked lines plotted on the screen, and a trimming and masking key 3 are provided together and every time the trimming and masking key 3 is pressed, the image extraction specified area for masking and trimming is switched in the predetermined order of the entirety (initial), A3 area, center part,... and the entirety. Consequently, the LCD display panel 2 is used as an area specification display device for masking and trimming and while no extra parts is required, the masking and trimming area extraction device which is good in operability is obtained without increasing the cost, size, and weight of the device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image extracting device for a digital micro league printer, and can be applied to other image processing devices.

[Prior Art] As an image extraction device for masking and trimming in a digital microreader printer, (1) as shown in Fig. 5, a large number of LEDs are installed on the X-Y axis near the screen.
5 are arranged, the LED to be lit is selected by key operation, and the area created by the lit LED on the X-axis and the lit LED on the Y-axis is designated area 4.

(2) As shown in Figure 6, four cursors 6 (the cursors are contact points) are placed on the X-Y axis near the screen.
It is known that the area defined by two cursors on the X-axis and two cursors on the Y-axis is designated as the specified area 4.

[Problems to be Solved by the Invention] In the above-mentioned conventionally known devices, the screen portion requires a considerable number of components, and the cost and machine size are 0.
There is a drawback in terms of weight.

[Means for Solving the Problems] The present invention provides a device that allows area designation (image extraction) for masking and trimming in a digital microreader printer to be easily operated without any extra components, that is, at low cost. In the present invention, a simple screen, a normal display device such as a magnification display and an error display in a printer, and a medium/small LCD panel used in L are masked and trimmed. By attempting to use the device also as an area specifying device in the event of an accident, the device is intended to be suitable for use without having to add extra parts.

That is, the present invention has the following features: (1) A projection screen 1, an LCD display panel 2 that displays an image corresponding to the marked line 1a drawn on the screen, and a trimming/masking key 3 are provided together, and the trimming/masking key Each time you press down, the designated image extraction area 4 for masking/trimming can be switched in a predetermined order, such as: Entire (initial) → A3 area → Center --- Entire Image extraction device in reader printer.

(2) It consists of a projection screen 1, an LCD display panel 2 that displays an image corresponding to the marked line 1a drawn on the screen, and a dot cursor drive key 3a and an entry key 3b on the LC, D display panel 2. A trimming masking key 3 is also provided, and the L
Set the first ξ dot cursor 4a on the CD display panel using the entry key 3b, then set the second dot cursor 4h in the same manner, and then set the first and second dot cursors 4a. , 4h on the diagonal is extracted on the LCD display panel 2 as an image extraction designated area 4 for masking and trimming.

An image extraction device in a digital microreader printer configured to display images.

(3) Claims <1) and (2> above, wherein a CCD is provided to read a simplified image of the projected image appearing on the projection screen 1, and the simplified image is also displayed on the LCD display panel 2. Image extraction device in digital microreader printer.

It becomes.

[Example] Fig. 1 is a perspective view of a digital microrep printer according to the invention, and Fig. 2 is a perspective view of an embodiment of the present invention according to the drawings, and Fig. 2 is a diagram showing the relationship between an image projection screen and an LCD display panel. Partial front view of , Figure 3 is LC
FIG. 4 is an explanatory diagram showing changes in the image extraction area designation state on the D display panel. FIG. 4 is an explanatory diagram showing the image extraction region designation state by the dot cursor drive key on the LCD display panel.

An embodiment of area designation (image extraction) for masking/trimming in a digital microreader printer will be described with reference to FIG. 3 (first embodiment) and FIG. 4 (second embodiment).

In the drawings, reference numeral 1 is a projection screen, 2 is an LCD display panel, and 3 is an operation unit equipped with a dot cursor drive key and an entry key. In both embodiments (1) and (2) below, the masking or trimming key of the operation unit 3 When pressed down, the LCD display panel 2 changes from the normal display (magnification display, error display, etc.) to the screen corresponding to the screen 1 and the marking lines, as shown in Figure 2. are common, and the area for image extraction is specified using the corresponding marked line 2a as a guide.

(1) From the state shown in Figure 2, each time you press a specific key,
As shown in Figure 3, the designated area is configured to change from the whole (initial heat → A3 area - center one, top right one, etc.). In this case, the areas that can be specified are several to several specified types. With 10 types, you can freely mask anywhere.
Although it cannot be trimmed, it has the advantage of being very easy to operate.

(2) From the state shown in FIG. 2, the area is specified using the dot cursor drive key 3a and entry key 3b on the operation unit 3. As shown in FIG.
is determined using the dot cursor drive key 3a and confirmed using the entry key 3b. Next, when the second point 4b is determined using the same operation method, a rectangular portion having the first and second point dot cursors 4a and 4b diagonally is extracted and displayed as the specified area 4.

(3) In both the first and second embodiments, the screen 1
The image extraction area 4 is specified based on the correspondence between the marking lines on the LCD display panel 2 and the LCD display panel 2.
Rather than looking at the marked lines, the image projected on the screen 1 is read once before copying using a reading element (not shown) such as a CCD that is naturally provided in a digital copying machine. Displaying the image on the LCD display panel 2 increases the effect of the indication.

[Effects of the Invention] Conventional devices require extra components such as LEDs and cursors for masking/trimming image area designation, but according to the present invention, these are conventionally provided, and the magnification and error Masking and
Since it also serves as an area specification display device during trimming, there is no need to add extra components, and therefore,
A masking/trimming area extraction device with good operability can be obtained without increasing the cost, size, or weight of the device.
