Abstract

PURPOSE:To improve the conversion efficiency of a recording pattern and to ensure the effective use of a display screen by designating a window setting job with continuation of the vector information and fetching selectively the picture information based on the vector information. CONSTITUTION:A window of an optional form shown in a figure (a) is set and inputted by a window input circuit 8a contained in a control means 8. The window information given from the circuit 8a is supplied to a vector forming circuit 9a of a window setting means 9, and a boundary area of the window is obtained in the form of a polygon consisting approximately of the continuation of vector information as shown in a figure (b). The vector informa tion is stored in a holding circuit 9b consisting of a memory as an address set on an X-Y coordinate axis.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an improvement in an image information processing device that reads out recorded image information, converts it into a new recording pattern, and takes it out.

(Prior art) Conventionally, computer technology has been used to selectively extract a portion of digitized image information, process it according to the purpose, and convert it into new image information for recording or display. has been carried out. Such image information processing is often used to analyze and process 1q of image information from medical equipment, resource exploration satellites, etc., which have recently undergone remarkable development.

A conventional image information processing apparatus has the configuration shown in FIG.

That is, after analog image information from an image input means 1 such as a television camera is digitized, digital image information recorded on a magnetic tape or the like is directly transferred to an input image holding means 2 consisting of a semiconductor memory circuit or the like. Supplied.

The pixels recorded in the input image holding means 2 are generally X-
Located at the specified address on the Y polar coordinate axis.

Now, from the image information recorded in the input image holding means 2,
Selectively extract only the information of a specified window (window),
It is assumed that processing such as analysis and processing is added and the image information is converted into new window image information.

The input address generating means 3 specifies a range (window (a)) to be selectively extracted from among the image information recorded in the input image holding means 2, as shown schematically in FIG. 5(a). The window (A) is located at two points (A,
B) and two points (a, b) on the Y axis are specified, and are represented by a rectangle surrounded by two parallel lines with the intersection of these points as the apex.

By supplying the address for window designation from the input address generation means 3 to the input image holding means 2, image information within the address designation range is supplied to the image data processing means 4.

The image data processing means 4 processes, for example, the shaded area (α) in FIG. 5(a) out of the introduced window (a) white image information, transforms it geometrically, and then converts it into an output address generating means. After receiving the signal from 6, the new I shown in FIG.
As image information of the new hatched area (β) within the window (b), an output image holding means 5 consisting of a semiconductor memory circuit, etc.
recorded in

At this time, the configuration and operation of the address generation means 6 when a new window (b) area is set are the same as those of the input address generation means 3. Further, the timing of address setting in each input/output address generating means 3.6 is controlled based on a control signal from the image data processing means 4.

Incidentally, processing such as analysis and processing of image information in the image data processing means 4 is executed while taking in various coefficient data set and recorded in the processing coefficient data holding means 41.

New window (b) recorded in the output image holding means 5
The image information contained therein is read out at any time as necessary and supplied to and displayed on an image output means 7 such as a cathode ray tube.

The operation of each of the above components is controlled by a control signal 81 from the control means 8, ensuring organic operation of the entire device.

In the conventional image information processing apparatus configured as described above, when considering the information processing in the image data processing means 4, the image information processing is always performed within the window (A) set by the input/output address generation means 3 and 6. (b) The amount will be applied in layers within the scope of (b).

By the way, the information in the vertically oblong hatched area (α) in the input side window (a) in FIG. When converting the image into part (β) and displaying it, especially within the output window (b), the area other than the display ((b) - β) is an area that has nothing to do with the display. In other words, the calculation processing for image conversion is performed based on the output window specification, and is performed within the range of the window (B), but the area that is not related to the actual display ((
Regarding (b)-β), extra arithmetic processing is also performed for image conversion.

In the above description, the output side window (b) was particularly explained, but the same can be said about the input side window (a).

This has the drawback that the processing time is longer for the area ((b)-β, (a)-α) and the arithmetic processing circuit is also large-scale.

Furthermore, when editing multiple images in a superimposed manner and displaying them on the same screen, the window designation ranges are mutually limited, making it impossible to display the screen efficiently.

(Problems to be Solved by the Invention) In conventional image information processing devices, when duplicating recorded image information or converting to new image information and recording and displaying it, the window settings are based on the X-Y orthogonal coordinate axes. As a result, unnecessary parts are generated in information processing, leading to a decrease in processing efficiency and hindering effective use of the display screen.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image information processing device that can improve the efficiency of information processing and make effective use of a display screen.

[Structure of the Invention] (Means for Solving the Problems) An image information processing device according to the present invention takes in and processes information in a specified window from among recorded image information, and then processes the information in a new window. An image information processing apparatus for converting into a recording pattern is characterized in that at least one of the window frames is specified by sequential vector information, and image conversion processing is performed based on this vector information.

(Function) Since the image information processing device according to the present invention specifies window frames using vector information that is sequentially connected, window frames can be set only to areas that are truly necessary for information processing, and unnecessary areas can be excluded. Therefore, unnecessary processing operations and inefficient screen displays can be eliminated.

(Example) Hereinafter, a first example of the image information processing device according to the present invention will be described.
This will be explained in detail with reference to the figures.

Note that the same components as in FIGS. 4 and 5 are denoted by the same reference numerals, and detailed explanations will be omitted.

FIG. 1 is a schematic diagram showing an embodiment of the present invention.

That is, digital image information passed through an image input means 1 such as a television camera is supplied to an input image holding means 2 comprising a memory circuit or the like.

In the image information itself recorded in the input image holding means 2, each pixel exists at a specified (addressed) position on the X-Y17) polar coordinate axis, as in the conventional case.

Therefore, the window to be set in the image information is specified by the control means 8.

That is, a window having an arbitrary shape as shown in FIG. 2(a) is set and inputted by a window input circuit 8a provided in the control means 8. The window input circuit 8a may be, for example, a digitizer, joystick, or mouse.
A positioning input means such as (use) is used.

The window information from the window input circuit 8a is supplied to the vectorization circuit 9a of the window setting means 9, and the window boundary area is approximately made up of a series of vector information as shown in FIG. 2(b). It is found as a square. This vector information is stored as an address on the X-Y coordinate axes in a holding circuit 9b consisting of a memory.

The window boundary area information recorded in the holding circuit 9b is
Separately! It is read out based on the control signal from the l+ control means 8, and is supplied to the address restriction condition setting circuit 4a provided in the image data processing means 4 as an address restriction condition.

Next, the input address generating means 3 is provided with an address setting circuit 3a and an input address limiting means 3b consisting of a comparator. In the input address restriction means 3b, address information sequentially sent from the manual address setting circuit 3a is input to the input address restriction condition setting circuit 4a.
It is successively compared with the address restriction conditions from , and each time it is determined whether or not it falls within the set window restrictions, address information outside the window is excluded, and a readout signal is supplied to the input image holding means 2 .

Therefore, when the sequential address signal from the address setting circuit 3a is supplied to the input image holding circuit 2 via the input address limiting means 3b, the window is , start from the address (po) on the X-axis of the highest point on the Y-axis, then reset the address in the X-axis direction to the initial value P1 of the next line, and change the Y address by one. Count up downward. Next, the X address is sequentially counted up from P1, and when P2 is reached, the count is turned back and the X address is reset to the next initial value P3. Thereafter, reading of the window area is performed by sequentially repeating scanning, and the recorded image information within the range of this reading is stored in the image data processing means 4.
transmitted to.

Note that the method of reading out the window area is not limited to the above scanning method, and the outside of the window area may be supplied as a read prohibition signal.

As described above, image information is selectively extracted from the input image holding means 2 and supplied to the image data processing means 4 according to the window boundary area information sequentially linked by vector information.

The image information processing means 4 analyzes and processes the image information selected in the window, converts it into geometrically new image information, and supplies the image information to the output image holding means 5. Note that the image information processing in the image data processing means 4 is executed while incorporating the coefficient data from the old processing coefficient data holding means as in the conventional case.

The output to the output image holding means 5 is based on the window address setting method consisting of the same circuit as the input side explained above.
The image is converted into an arbitrary shape address and recorded/displayed.

FIG. 3 shows the state of the input/output side window according to this embodiment in comparison with FIG.
)) shows the case where a rectangular window (a) similar to the conventional one is formed.

On the other hand, on the output side, as indicated by diagonal lines in FIG. 3(b), a window (b) having a shape that follows the image conversion display area (β) is set by a window input circuit 8a provided in the control means 8. This is what was entered.

That is, similarly to the input side, the window information from the window input circuit 8a is supplied to the vectorization circuit 9a, grasped and converted as a series of vector information, and then sent to the holding circuit 9b.
is memorized.

The window boundary area information recorded in the holding circuit 9b is
The data is read out and supplied to the address restriction condition setting circuit 4a.

On the other hand, the output address limiting means 6b consisting of a comparator receives the signal from the address limiting condition setting circuit 4a and the signal from the address setting circuit 6a, and generates a read signal for excluding addresses outside the specified window. , a control signal for selectively extracting the image-converted signal is supplied to the output image holding means 5.

Therefore, as shown in FIG. 3(b), the output image holding means 5 receives only the information that has been image-converted according to the window set by the vector information and is recorded therein from the image data processing means 4. .

The image information in the new window recorded in the output image holding means 5 is read out as needed by a control signal from the control means 8, and supplied to the image output means 7 such as a cathode ray tube for display.

Incidentally, the operation of each component is controlled by a control signal 81 from the control means 8, as in the conventional case, and organic operation of each element is guaranteed.

As described above, since the image information processing apparatus of the present invention performs image conversion based on the window setting means using vector information, it is also possible to convert special geometric shapes.

As a result, there is no need for continuous output of image information or unnecessary access to recording during conversion, making it possible to shorten processing time and improve efficiency.

In the above embodiment, a case has been described in which the present invention is applied to both the input side and the output side of image information, but it is of course possible to apply the present invention to only one side.

[Effects of the Invention] The image information processing device according to the present invention specifies the window settings as a series of vector information, and selectively captures the image information based on this vector information, thereby efficiently converting the recording pattern. This makes it possible to use the display screen without waste.
