Embodiment An embodiment according to the present invention will be described below in detail with reference to the accompanying drawings.

<Description of Configuration (FIG. 1)> FIG. 1 is a block diagram of a video printer according to the present embodiment.

In the figure, reference numeral 1 denotes an input terminal for inputting various videos.
Reference numeral 2 denotes a known decoder 2, which converts a video signal input from an input terminal 1 into Y, RY, and BY color difference signals.
Reference numerals 3 to 5 denote A / D converters for converting the signals converted by the decoder 2 into digital data. Reference numeral 6 denotes an image memory, which is controlled by an image memory controller 7;
The digital data output from the A / D converters 3 to 5 is stored, and the internal data is output in synchronization with a video synchronization signal. A multiplexer 8 stores data from the A / D converters 3 to 5 and an image memory 6 as shown in FIG.
Is selected and output in accordance with "L / H" of the signal supplied to the selection terminal 8a. The output of the AND gate 27 is connected to the selection terminal 8a. Only when signals from both the through / memory image switching switch 17 and a binary image memory 14, which will be described later, are "H", the signal from the image memory 6 is output. You can select data. 9-11
Is a D / A converter for converting each digital data of the color difference signal output from the multiplexer 8 into an analog signal again, 15 is an encoder for returning it to a video signal again, 16 is a video output terminal, for example, a monitor device, etc. External connection terminals for connecting

The output of the multiplexer 8 is also supplied to a head driver indicated at 20. The head driver 20 drives a head 21 for print output to form a visible image, and also performs a process of converting input color difference data into a Y, M, C color system. However, since the conversion and printout itself depart from the gist of the present invention, the description is omitted.

Reference numeral 12 denotes a scanner which reads an original image in units of one line (equipped with a line CCD) and outputs it as serial data, which is a so-called handy scanner. Reference numeral 13 denotes a binary image memory controller, which converts serial data output from the scanner device 12 into binary data in the binary image memory 14 under the control of a system computer 18 to be described later, and writes the converted data. It controls a reading process described later. Accordingly, by moving the scanner device 12 over the surface of the original to be read, a binary image of the original image (an image in which one bit corresponds to one pixel) is developed in the binary image memory 14. It becomes possible. The reading of the original image by the scanner device 12 is started by operating a scanner start switch indicated by 22, and the end is ended by the operation of a scanner stop switch (not shown). The processing may be terminated at the time when the processing is completed. Also, since the binary image memory 14 is connected to one input side of the AND gate 27 described above, when the output from the through / memory image switching switch 17 is set to "H", the binary image The pixel data is supplied to the selection terminal 8a of the multiplexer 8. Conversely, when the output of this switch is set to "L", AND operation is performed regardless of the contents of the binary image memory 14.
The output of the gate 27 becomes "L", and the multiplexer 8 selects the data from the image memory 6.

Reference numeral 18 denotes a system controller (referred to as a system controller) for controlling the entire apparatus of the present embodiment, for example, a binary image memory controller by operating a scanner start switch 22.
Drive control of the print driver 13 and control of a mechanical driver related to print processing indicated by the head drivers 20 and 19 in accordance with the operation of the print start switch 23 execute print processing and the like.

Reference numerals 24 and 25 are a horizontal switch and a vertical switch for instructing the horizontal and vertical scroll amounts of the image developed in the binary image memory 14, respectively. Specifically, based on the operation of the horizontal switch 24 and the vertical switch 25, the system controller 18 controls the binary image memory controller 13
The scroll is achieved by controlling the start position and timing of the read address. Also,
Reference numeral 26 denotes an image memory freeze switch. When this switch is turned on, the system controller 18 controls the image memory controller 7 and fetches the digital data of the video image input to the input terminal 1 into the image memory 6 at that time. Let
Reference numeral 28 denotes an inversion switch, which can invert the output of the binary image memory 14 based on ON / OFF of the switch.

<Description of Processing Outline (FIGS. 2 and 3)> An outline of the operation of the video printer according to the present embodiment in the above-described configuration will be described below.

In the embodiment, a binary image as shown in FIG. 2 (c) is input, and a hatched portion (a region where a pixel is "1") is input.
In FIG. 2, the image shown in FIG. 2 (b) is selected, and for the other images, the image shown in FIG. 2 (a) is selected to finally obtain the image shown in FIG. 2 (d). Is what you do.
By operating the inverting switch 28, the output from the binary image memory 14 is replaced with "L / H", so that it is also possible to invert each area to be combined. is there.

Hereinafter, a process for realizing this will be described with reference to the configuration of FIG.

First, the scanner start switch 22 is operated, and the binary image is inputted from the scanner device 14 to the system controller 18 (FIG. 2 (c)).
Give instructions to read. Upon receiving this instruction, the system controller 18 controls the binary image memory controller 13 to perform a process of binarizing the data output from the scanner device 12 and writing the data into the binary image memory 14. The second
The pixels in the shaded area in FIG. 3C correspond to "H" in the logic level, and the other pixels correspond to "L" in the binary image memory 14.
Will be expanded to. Then (or earlier), the image memory freeze switch 26 is operated to read the image of FIG.
To be stored. When the storage in the image memory 6 is completed, the image of FIG. 2 (b) is taken in from the input terminal and the output of the through / memory image switching switch 17 is set to "H", whereby the monitor connected to the output terminal 16 is turned on. The image of FIG. 2D can be displayed on the device. At this time, by turning on the print start switch 23, the image displayed at that time (FIG. 2 (d))
Can be printed out. When the inverting switch 28 is turned on, the effect is substantially the same as inverting the bit developed in the binary image memory 14, so that the masked area of each image is displayed (printed). It becomes possible.

Further, in this embodiment, by operating the horizontal switch 24 and the vertical switch 25, the position of the image developed in the binary image memory 14 can be substantially changed.

For example, when the image of FIG. 3A is expanded in the image memory 6 and the image of FIG. 3B is input as a through image, as shown in FIG. Let us consider a case where a binary image shifted from the position is input. In this case, by operating the horizontal switch 24 and the vertical switch 25, it is instructed to scroll by "Χ" in the horizontal direction and "Y" in the vertical direction, and as shown in FIG. 2 It is possible to obtain the same result as FIG.

As described above, according to the present embodiment, it is possible to cut out a desired area of one image, synthesize the desired area with another image, and output the resultant image.

In addition, since 1-bit surface area information for switching between a through image and a memory image for printing from a high-definition scanner or the like is read, characters and illustrations of an arbitrary color can be combined in a print image, and a greeting card or the like can be used. Can be easily created.

Although the embodiment has been described based on the Y color difference signal, R,
G, B type, C, M, Y type or the like may be used at all.

In the embodiment, the position of the cutout area is moved by controlling the read address and timing of the binary image memory 14, but this is realized by moving (transferring) the image itself of the binary image memory 14. You may.

[Effects of the Invention] As described above, according to the present invention, not only a composite image of two images is simply created, but also, for example, alignment of which part of each image is to be composed is performed by a simple operation. It can be realized.

Further, when the relationship between the combining and combining of two images is incorrect, the relationship can be restored by a simple operation.
