Description

[Detailed description of the invention] imaging device Technical field The present invention includes an input device, means for detecting movement of the input device relative to a surface, and a drawing instrument. followed the motion of the input device to simulate the creation of patterns on the surface. The present invention relates to an image device including a display means for displaying a pattern. Regarding the types listed Such devices are cited below.

Background technology Although devices of the type described have been developed in recent years, there are major deficiencies in current devices. The dots accurately simulate the effect of veining on the canvas. There is a point where it is impossible to do so.

Disclosure of invention According to the invention, an imaging device of the type described is used in a dry (dry) manner in the finished image. ) to store data representing the amount of paint and wet (moisture) paint, respectively. a first and a second storage section, and a method for combining data in the first and second storage sections; and a connection connected to the first and second storage parts for generating the final image on the display means. Simulate means and the effect of increasing or decreasing the degree of wetness The apparatus further includes processing means for modifying the data in the first and second storage units in order to It is characterized by being able to grow.

Applicants have used known devices to accurately simulate veining on canvas. One reason is that these devices do not work with paint or canvas. I realized that this is due to the inability to reproduce the effects of moisture.

These effects are very important in painting and are often not perfected. Used to create special effects in veiling. Painte such as paint drying, fading, color bleeding, and stains. The various effects are time dependent. These effects were created by painters using chalk and pastel. It is used, for example, to smudge or fix images (soft colors with a matte finish). Ru.

It is important to note that for multicolor images, there is a pair of first and second memories for each color component. That's true.

Typically this storage is a frame memory coupled to the monitor.

In one application, the treatment means that the applied paint dries over time. can be automatically simulated. Therefore the paint is regular is effectively transferred from "wet" storage to "dry" storage at intervals.

In more advanced examples, the processing means can simulate effects such as dirt, etc. It is possible to perform other functions such as

This feature is used in wet storage, for example while painting or spreading, etc. Including modification of the paint position and/or density function. In addition, “move” behavior can run in real time or at intervals set by the operator. Wear. Prevents drying by “moving” from wet storage to dry storage. In addition to It can be simulated by "moving" to.

Examples of some of the effects that can be achieved using the present device are described below.

1. Paint drying (drying) Paint is used in the wet storage area, and then processing means dry storage at each cycle time. Copy the ratio to parts. The effect on the display does not change, but the wet memory The number of ``raw'' colors possible for each color decreases steadily. The dirt effect is then implemented in the wet storage section. The effect is that the overtime can be reduced. Do not ``bring moisture'' into the dry storage area. to copy the part of the dry storage part to the wet storage part, and then "dry" is copied to the wet storage part. Return to the memory section.

Of course, even more brush work could be used for wet storage instead. Wear.

The criteria for "copying" or "moving" paint from one storage to another are: Including etching paint from one store and repainting to another store. is important. In this operation, the merge (absorption merger) and the used Ching brushes can have the same or different properties depending on the desired effect. Ru. a) All two-dimensional sizes, including the following, depending on the brush “characteristics” b) 3D shape (i.e. 2D size and height, the latter indicating concentration) C) Single color or fabric color d) the total concentration limit (i.e. the scale factor applied to limit the maximum concentration) ) e) Joining algorithm 2. Drip (drops), spread (expansion), run (color bleeding) The drip effect can be pre-jammed to simulate drip painting. This is achieved by repainting the nulled brush trajectory. Regulation time Beyond that, these drips are automatically built up by repainting. It will be done. This repaint is initiated along the trajectory of other paint strokes (used In the direction of gravity (which can be defined by the user), this is of course achieved with better brushing.

The user can stop the process at any time, manually edit the wet storage, or Dry tape by using an image grab-back device. Fix wet storage to the image as an int. Paint is activated when requested. There is no reason why the memory unit cannot be moved at the same time. Gravity is the canvas To specify the direction and magnitude of the upward (typically downward) movement, the vector can be placed on the screen as a user interface. The user is , determines the size and density of the brush used when a spread effect is requested. Determine the degree of absorbency of the canvas.

Spread simulates the uneven surface effect for very wet brushes Etch into the wet storage area with a larger, lower density brush and This can be achieved by repainting. What are the other effects of the brush characteristics mentioned above? This can be achieved by changing the

3. Fade/Mixing When paint is applied to a canvas, it changes color as it dries. can be mixed with wet colors already used, etc. These effects The result is a processing means to "move" paint from wet storage to dry storage. This can be achieved by appropriate programming.

For the fade, the wet memory area is etched with an etching brush to preserve the full effect. Merge or use dry storage areas at lower densities to reduce the total paint density. A brush that can be used can be dyed. All of these effects allow this device to operate repeatedly. return, thereby controlling at what point you want the image to be fixed by the grab-back operation. Repetitively reach the desired effect.

Brief description of the drawing FIG. 1 is a block diagram of the apparatus of the present invention, and FIG. 2 is a block diagram of the apparatus of the present invention, and FIG. Figure 3 is a block diagram of the image storage unit shown in Figure 1. FIG.

BEST MODE FOR CARRYING OUT THE INVENTION An example of an imaging device according to the invention will be described below with reference to the accompanying drawings.

The device shown in FIG. 1 can be divided into two basic parts. These are main part 1 and group It is composed of rough subsystem 2.

The division is indicated by the dotted line in FIG. The main part is multitasking and multiuser operation. The 68020 is based on a system that runs on the UNIX operating system. It is a croprocessor. The main part is an I10 processing device 3 connected to a keyboard 4; Digitizing tablet 5 and accompanying pen 31, system disk 6 and other data sources (not shown). I10 processing device 3 is a system The internal connection bus (SIB) 7 is connected to the ROMSR. It is connected to AM memory 8, CPU 9, and interface adapter 10.

The interface adapter 10 defines the color components of the pixels of the image at high resolution. connected to several high-speed image disks 11 holding data, and said adapter It is connected to the graph subsystem 2 via an interface 12 . mentioned earlier As the main part has the structure of the prior art, the details will be omitted. However, 5IB7 is EP-A -033'2417 for details.

The program that executes the main part is a "process", and the input is controlled by the operator. read from the digitizing tablet 5 and send it to the graph subsystem 2. The responses of the main unit to these inputs are displayed on the graph monitor 30. essence In general, this system has the advantage that the main part can accomplish a large amount of calculations, and the control data is Only a small amount of data is allowed to pass through the graph subsystem.

This subsystem 2 is different from the main part 1 in that it creates and manipulates graph objects. The main part is good for controlling disk and tape peripherals from input/output. It is relatively easy to program.

This graph subsystem 2 has an interface that connects the graph section to the main section 1 and connects it to the bus 14. It consists of 13 surfaces. Bus 14 has five image processing units (GIP) 15-19 connected to.

In this example, the image has four color components: cyan, magenta, yellow, and and black, with a separate GIP for each color. In this way, GIP15 Dark color component, GIP16 is magenta color component, GIP17 is yellow component, GIP18 processes the black component. If this image can be represented by several different color components For example, if you want red, green, and blue, you can use only 3 GIFs (and the ones listed below). Addition of mask GIF) is required. GIP15-18 are arranged in parallel. The advantage is that each component of each pixel in the image can be processed in parallel, reducing the total processing time. The advantage is that the processing can be reduced to 174 times compared to using a single processing device. Using GIP A further advantage of using the It has a bit slice processor. The fifth GIP19 is - or more masks or to separate other features, such as menus, etc. provided.

FIG. 2 shows one configuration of the GIP in FIG. 1. Each GIP is a bit slice processor 20 and is connected to a bulk memory 21. This memory 21 is holds image data, brush outlines, and text, and serves as a virtual image memory. used. The bit slice processor 20 has a pair of frame memories 22.2. 3, and each frame memory has a size of 1280 x 1024 and a depth of 8 bits. has. In GIP15-18, each frame memory holds 8-bit data. However, in mask GIP19, each frame memory has an 8-bit mask or two can be used to hold separate 4-bit masks. Furthermore, GIP19 One frame memory in the It can be used to display the overlay of a 4-bit brain. The overlay is a drawing line , consisting of a box and the kind displayed on the monitor.

The 8-bit data in each frame memory 22.23 is scrolled and amplified. , each operating in a conventional manner to perform one or more of the functions of zooming. 4-bit "nibble" to scroll, amplify, and zoom circuits 24-27. The outputs of these circuits are sent to the mixer circuit 28. GIP15 according to the mask memory stored in the frame memory 22 for -18 and each of the frame memories 22 regarding GIP15-18. The data from each of the system memories 23 are mixed. This mixer circuit operates in two stages. Details are given in EP-A-0344976.

The output of the mixer circuit 28 is directed to a two-stage color converter 29 and a monitor screen 30. In order to properly control the above display, convert the four color component data into three color component data. In other words, it converts to red, green, and blue.

In use, images are stored on the high speed image disk 11 and these images are can be generated by scanning the original watermark or other representation, or or could be generated electronically using an electronic paintbrush. The main part 1 is Related parts of these images are stored inside the bulk memory 21 in GIP15-18. or "paged" outward, or the brush outline is in bulk memory in GIP19. 21 to be loaded or unloaded.

Since the interface adapter 10 can control the disk 11 independently, It has its own microprocessor 68020. GIP15-18 is based on main part 1. Various operations are performed on the image in the bulk memory 21 based on the G so that the IF accesses an address in an image that is not currently in its bulk memory The next time the attempt is made, that portion of memory is written back to disk and a new portion is read. be absorbed. After GIP completes processing, the frame memory data is then crawl, zoom, modulate and/or amplify if necessary and mix in circuit 28. converted to monitor format, and then displayed.

If main part 1 wants to display a menu on the screen, these are called "overboards". The mask GIP frame memory 23 is written in a manner known as a mask GIP frame memory 23.

In normal paint mode, the operator selects paint and brush outlines.

This brush contour can define, for example, a Gaussian distribution, and this contour is defined by GIP15-19 are stored in a specific portion of each bulk memory. The operator then inserts the pen 31 into the tablet. "Paint" by moving across the pen 31 and the position of the pen 31. is monitored by main part 1, which then sends the paint data to GIP15-18. It also instructs the respective frame memories 22 to be loaded. in this way, At each position of the pen 31, the GIF is determined according to the well-known formula below. Positioning is performed at each pixel surrounded by a brush rask in the frame memory 22. Calculate data values so that

New pixel value = (1-α) x old pixel value + paint value where α is in the range 0-1 coefficient, the current value defined by the brush contour and used in this operation. with a percentage value selected by the operator that defines the maximum percentage of paint to be obtained. It is obtained by the product. The new pixel value is written to the frame memory 22 and the bulk It is automatically copied to the appropriate location in memory 21.

The contents of frame memory 22.23 of each GIPI 5-18 are mixed and (GIP 19) under the control of the data stored in the mask frame memory 22 as described above. will be displayed. First, frame memory 2 is set so that non-mixing is effectively done. 3 is not used.

The effect of moisture in applied paint in conventional electronic delineation (bainting) has not been considered. However, this does not mean that the frequency of GIP15-18 is It is possible to process this by using the system memory 23. essentially a picture The appearance of the image changes over time under the control of the main unit 1 and GIPs 15-19. this thing to modify the contents of the frame memory 22 and the bulk memory 21 therefrom. This can be done more destructively, and in the preferred embodiment frame memory 23 is used. be done. In this regard, the frame memory 22 is referred to as the "dry J memory". The frame memory 23 is then referred to as "wet" storage.

In this example, the previously "painted" image is transferred from disk memory 11 to the GIP 15-18 to the bulk memory 21 and from there to the corresponding frame memory 22 will be downloaded to. This image is designated by reference number 4o in FIG. pay The printing operation is performed in the conventional manner by the operator selecting the brush contour. The paint color started and applied and the movement of the pen 31 are monitored by the main unit l. Part 1 stores the journal (shaft neck) at a specific position on the brush path in storage part 8. do. In addition, the effect of moving brushes is that the resulting color information is GIP15-18 in the conventional manner except that it is stored in memory 23. is generated. An example of the content of one of the frame doors 23 is shown in FIG. 41. At the same time, the brush path is GIP19 (mask frame memory) is recorded in the frame memory 23 of. In the case of masked frame memory, the data data effectively defines monochrome images.

The result of this operation is shown in FIG. is displayed on a monitor 30 via a mixer 28 controlled by the screen. this With this method, the image seen on the monitor screen 30 is obtained non-destructively. The image in the frame memory 22 has not been modified.

When the operator is satisfied with the image currently appearing, the operator can take bulk notes. 21 is modified according to the displayed image under the control of the mixer circuit 28. You can activate the "Grab Back" device.

The method by which the mixer circuit 28 operates is to generate a mask frame according to the following formula. under the control of the masking value read from the corresponding pixel in the frame memory 22. The algorithm is applied to each pixel read from frame memory 22.23 of GIP15-18. It is about applying rhythm.

Display pixel = β x FS23 + (1 - β) FS23 where β is the mask frame It is obtained from the value corresponding to the allocation in memory 22.

The invention is designed to frame so that the effects of moisture and time on applied paint are taken into account. To automatically modify an image stored in a memory 22. This thing is wet The effect of moving paint from frame memory 23 to dry frame memory 22. This is achieved by occurring. In practice, this move is a conventional ``merge'' ” brush on the image in frame memory 22, The merge brush (determined by the journal stored in advance in the storage unit 8) trace the path of the first brush used in the frame memory 23) The movement is performed by etching brushes along the same path in the frame memory 23. This is achieved by using Two brushes do not necessarily have the same outline. It doesn't matter, the different effects are based on the contours of these brushes and the time interval during which the movement movement is performed. The merge brush can be achieved by selecting the appropriate merge brush according to the algorithm below. Operate.

New pixel value = γXFS23 + (1 - γ) FS22 where γ is the corresponding brush rask value and paint that can be moved from the frame memory 23 in one operation. Multiply the maximum amount by a preselected percentage selected by the operator corresponding to It can be obtained by

The etching brush operates according to the following formula.

The maximum value of p' = (s, (p-f (c-s))) where, p' is the final image pixel, p is the first image pixel, C is the color to remove, S is the base color (i.e., controls the amount of color that can be etched as set by the user) (default to 0), and f is a coefficient between O and 1, and the current value defined by the brush contour and the removable This is the value obtained by multiplying the amount of paint by the percentage that defines the maximum amount of paint that can be applied.

The first effect of these moving actions is also applied to the merging brush fading action. When the image is not edited to be displayed, it will not be detected on the monitor screen 30. but However, this effect becomes evident during sequential bailing operations. Because it's new Mix the wet paint left in the frame memory 23 with the wet paint left in the frame memory 23. The amount of wet paint still present is reduced to This is because the result is different from mixing paints in progress.

Other effects can be achieved as indicated above. For example, the dirt effect is brush (to frame memory) with a larger contour than the first brush by a Gaussian amount. Different editable to look like dirt effects, perhaps with a rougher distribution than cloth Obtained by reapplying in (lower) concentrations. This effect can be applied with various brushes. In the wet frame memory with repeated automatic brushing in the type of This can be stopped by the operator at any time when the desired effect has been achieved. Can be stopped. Brushes added to wet frame memory are the first paint stains. It can be a "random data" brush, like a random contour brush. This should not be confused with. Random contours can be created using raster patches (e.g. contains a random distribution of data that controls the amount of data (into merge), but Rashi controls the amount by which the base image data is randomized in terms of individual pixel values. It can have, for example, Gaussian contour control data in a raster.

When you finally don't want to modify an existing image for an effect, you can It is only necessary to modify the data in the default frame memory.

The journal keeps track of the brushes, so the main part can track these additions for an effect. Unable to stay away from the traces. This creates a wet splashy effect. Existing outside of any of the main traces of existing brush work in dry storage to obtain Random little "smudges" in the paint that appear, or in the tangent to the brush trace. It can include "runs" (color blurs).
