[Action] animation image creation device and the above-described configuration
In the method , the weighting factor is multiplied by a fade factor, and the multiplied value is further multiplied by the image data. Therefore, fade-in or fade-out can be easily realized.

Further, predetermined image data is selected from a plurality of image data, and the output of the multiplier 32 corresponding to the selected image data is replaced by the replacement data calculated by the calculator 36. Therefore, for example, when creating an animation in which the beginning and end of a scene have the same shape pattern, the shape pattern can be selected as an arbitrary shape pattern.

And a variety of expressions are possible.

[0012]

FIG. 2 shows the configuration of an embodiment of an animation image creating apparatus using the multiple interpolation method used in the present invention. 1 (1 ₀ to 1 _n-1), respectively stores the arbitrary shape pattern (image data). Memory 3
(3 ₀ to 3 _n-1) stores weighting coefficients w ₀ through w _n-1, respectively. Multiplier 2 (2 ₀ to 2 _n-1), the image data memory 3 ₀ read out from the memory 1 ₀ to 1 _n-1
To 3 _n−1, and outputs the result to the adder 4. The adder 4 adds the input data and supplies it to the memory 5 for storage.

In the case of this embodiment, the memory 3 described above
It is configured as shown in FIG. That is, the memory 21 ₁ to the memory 21 _n-1 stores the weighting coefficients w ₁ to w _n-1 corresponding to the image data stored in the memory 1 ₁ to 1 _n-1, respectively. The memory 23 stores a fade coefficient F. The multipliers 22 _{1 to} 22 _n−1 are stored in the memory 21 ₁
To the image data read from the 21 _n-1, the memory 23
Multiplied by the fade coefficient read from the memory 25 ₁
To 25 _n-1 . The output of the multiplier 22 ₁ to 22 _n-1 is also supplied to the calculator 24. Calculator 24 adds the supplied from the multipliers 22 ₁ to 22 _n-1 data, subtracts the added value from 1.
The output of the arithmetic unit 24 is supplied to the memory 25 _0, is adapted to be stored.

Next, the operation will be described. Memory 1 ₀ to 1 _n-1 from the read image data P ₀ to P
_n-1 is supplied to the multiplier 2 ₀ to 2 _n-1, is multiplied memory 3 ₀ to ₀ to 3 _n-1 from the read weighting coefficient w w _n-1 and. The output of the multiplier 2 ₀ to 2 _n-1 is supplied to the adder 4 are added and stored in the memory 5 as data P.

The data P is represented by the following equation when expressed by a mathematical expression.

(Equation 1)

[0016] By varying the shape pattern P ₀ to the weighting factor w ₀ through w _n-1 of P _n-1 on the time axis, moves along with the shape pattern to be generated, the animation. However, when the weighting coefficient is changed to an arbitrary value,
In many cases, the generated shape is inappropriate. Therefore, a constraint condition as shown in Expression 2 is given to the weighting coefficient w _i .

(Equation 2)

That is, a constraint condition is given so that the sum of the weighting coefficients w _i of n shape patterns becomes 1. Thus, if the prepared of n-shaped pattern to create an animation, to generate weighting coefficients w _i satisfy the number 2 of the constraint equation, the weighting factor w _i is the n-1 free Become. Therefore, the weighting coefficient w ₀ can be obtained from Expression 3.

(Equation 3)

For convenience, the shape pattern P ₀ corresponding to the weighting coefficient w ₀ is called a base image.

FIG. 3 shows a configuration for calculating the weighting coefficient w ₀ corresponding to the base image described above. That is, in this embodiment, the weighting coefficients stored in the memory 11 ₁ to 11 _{n -1} w ₁ to w _n-1
There is supplied to the memory ₁₂₁ to 12 _n-1, while being stored and supplied to the calculator 13. Operator 13 performs an operation shown in Formula 3 described above, and supplied to the memory 12 ₀ the operation result as the weighting factor w _0, for storage. That is, when the weighting factor w ₀ Other (n-1) weighting coefficients w ₁ to w _n-1 is determined, can be determined by calculation from these values.

In the embodiment shown in FIG. 1, the weighting coefficient is calculated based on the same principle as that shown in FIG. That is, the weighting coefficients w ₁ to w _n-1 read out from the memory 21 ₁ to 21 _n-1 includes a multiplier 22
_{1 to} 22 _n−1 and multiplied by the fade coefficient F read from the memory 23. The multiplication result is supplied to the memory 25 ₁ to 25 _n-1 as it is as a new weighting coefficient W ₁ to W _n-1, are stored. The output of the multiplier 22 ₁ to 22 _n-1 are supplied to the calculator 24, calculation shown in Equation 4 is executed.

(Equation 4)

[0021] By this operation, the weighting coefficients W ₀ in consideration of fading coefficients is calculated corresponding to the base image, is supplied to the memory 25 _0, it is stored.

The memory 25 ₀ to 25 _n-1 in FIG. 1, will be arranged in place of the memory 3 ₀ to 3 _n-1 in FIG.

The fade coefficient F changes linearly from 0 to 1 from time t ₀ to t ₁ as shown in FIG. It is constant at ₁ from time t ₁ to time t ₂ , and the time t
From ₂ to time t ₃ decreases linearly from 1 to 0. Therefore, at time t ₀ , the image data P becomes the base image P ₀ . Further, between the time t ₀ to time t ₁ will be shape pattern P ₁ to P _n-1 is added to the base image P ₀ slowly (i.e., fade in). Since the fade coefficient F is ₁ from time t ₁ to time t ₂ , the animation is the original data. In the range of the time t ₃ further from the time t _2, the shape pattern P ₁
To P _n-1 are gradually removed from the base image P ₀ , resulting in a so-called fade-out state. Since the fading coefficient F becomes 0 at time t _3, the base image P ₀ again as in the time t _0.

[0024] In this way, begins with a base image P _0, the animation ends with a base image P ₀ is easily created.

The fade coefficient shown in FIG. 4 is an example. In the case of fade-in, F = 0 starts and F = 1.
The characteristic does not necessarily need to be linear as long as the characteristic increases monotonically. Also, in the case of fade-out,
= 1 and monotonically decrease to F = 0, and does not necessarily have to decrease linearly. Various variations of animation can be created by changing the time required for fade-in or fade-out and the rate of increase (decrease) of the fade coefficient.

Next, a specific example of animation will be described. Now, as a basic shape pattern, FIG.
It is assumed that there are three spheres, a cube, and a pyramid as shown in FIG.
It is assumed that the weighting coefficient w _{0 of the} sphere is always 0 in a period of 24 seconds. Also, the weighting coefficient w _{1 of the} cube
Increases linearly from 0 to 1.0 from 0 to 12 seconds and decreases linearly from 1.0 to 0 from 12 to 24 seconds. Further, the weight coefficient w _{2 of the} quadrangular pyramid decreases linearly from 1.0 to 0 from 0 to 12 seconds, and linearly increases from 0 to 1.0 from 12 to 24 seconds. .

When the weighting coefficient is changed in this manner for 24 seconds, the animation for 24 seconds is shown in FIG.
Animations that change as shown in FIGS. 7A to 7F and FIGS. 7G to 7K are obtained. That is, in this case, first, the cube component is gradually added to the shape of the quadrangular pyramid, and the cube component is removed again to return to the shape of the quadrangular pyramid. In this embodiment, since the weighting coefficient w _{0 of the} sphere is always 0, the influence of the shape pattern of the sphere does not appear.

On the other hand, as shown in FIG.
Increases linearly from 0 to 1 from 0 to 6 seconds,
It is held at 1 from 6 seconds to 18 seconds, and from 18 seconds to 24
If set to decrease linearly from 1 to 0 over seconds, the weighting factor W ₀ decreases linearly from 1 to 0 from 0 to 6 seconds and remains 0 from 6 to 18 seconds;
It increases linearly from 0 to 1 from 18 seconds to 24 seconds. Further, the weighting factor W ₁ is increased from 0-0 seconds to 6 seconds curvilinear to 0.5, 0 to 6 seconds to 12 seconds.
It increases linearly from 5 to 1. And from 12 seconds to 18
Linearly decreases from 1 to 0.5 down to seconds, from 18 seconds to 2
Curvewise decreases from 0.5 to 0 by 4 seconds. Further, the weighting factor W ₂ multiplied by fading factor increases from 0-0 seconds to 6 seconds curvilinear 0.5, decreases linearly to zero from 0.5 to 6 seconds to 12 seconds. Also from 12 seconds to 1
It increases linearly from 0 to 0.5 until 8 seconds, and from 18 seconds to 2
Curvewise decreases from 0.5 to 0 by 4 seconds.

As shown in FIG. 8, when the weighting coefficient is set in consideration of the fade coefficient, FIGS.
In addition, animations as shown in FIGS. 10 (g) to 10 (k) are obtained. In this example, starting with a sphere,
A quadrangular pyramid component is added thereto, and further a cubic component is added. After that, the cube component and the quadrangular pyramid component are gradually removed, and the process ends again with a spherical shape pattern.

FIG. 11 shows the configuration of a second embodiment of the animation image creating apparatus according to the present invention.

In this embodiment, the weighting coefficients w _{0 to} w _n-1 are stored in the memories 31 _{0 to} 31 _n−1 , and the fade coefficient F is stored in the memory 33. Multiplier 32
_{0 to} 32 _n-1 multiply these weighting coefficients w _{0 to} w _n-1 by a fade coefficient F, and select the selector 34 and the selector 37
Output to The selector 34 determines a predetermined (i-th) value (α _i-1 = F ×
w _i−1 ) is removed, and the remaining value is output to the calculation unit 36. The operation unit 36 adds the input value, and subtracts the value from 1 to obtain a value β. That is, the calculation shown in Expression 5 is performed.

(Equation 5)

The output of the operation unit 36 is supplied to a selector 37. The selector 37 removes α _i−1 from the values α _{0 to} α _n−1 supplied from the multipliers 32 _{0 to} 32 _n−1 in accordance with the instruction from the selection unit 35, and replaces it with the operation unit 36. Output the input data β. Values α _j other than α _i−1 are output as they are. In this way, the memories 38 _{0 to} 38 _n
The _-1, weighting coefficients W ₀ to W _i and W _i-2 and W _i to W _n-1 is stored.

In this embodiment, the fade coefficient F is set to 0
, The outputs of the multipliers 32 _{0 to} 32 _n−1 are all 0. Therefore, the outputs of the selector 34 are all 0, and the output of the operation unit 36 is 1. Therefore, selector 3
7 is only i-th weighting factors W _i-1 which is designated by the selection unit 35 a 1, the other coefficients W ₀ to W _i-2 and W _i
Through W _n-1 to 0. Thus, the base image can be arbitrarily selected from n shape patterns by operating the selection unit 35.

On the other hand, when the fade coefficient F is 1, the value β output from the operation unit 36 is the same as the output of the multiplier 32 _i-1 . Therefore, the output of the weighting factor W ₀ through W _n-1 multipliers 32 ₀ to 32 _n-1 is supplied as it is. When the fade coefficient F is a value between 0 and 1, fade-in or fade-out is performed according to the direction of the change.

FIG. 12 shows a third embodiment. In this embodiment, the selector 39 is connected to the n-
One output and one output of the operation unit 36 are supplied. Then, the selector 39 inserts the value β supplied from the operation unit 36 into the i-th value and supplies the value β to the memory 38 _i-1 .
Other configurations are the same as those in FIG.

That is, in this embodiment, the i-th shape pattern selected by the selector 35 can be used as the base image, as in the case of the embodiment of FIG. Other operations are the same as those in FIG.

FIG. 13 shows a fourth embodiment. In this embodiment, the selector 40 is the i-th select only values F × w _i-1 from the n input of the multiplier 32 ₀ to 32 _n-1 in response to the selection of the selection unit 35, arithmetic unit 42. Computing unit 41 to obtain the value γ by adding the outputs of the multipliers 32 ₀ to 32 _n-1. The operation unit 42 calculates the value F × w supplied from the selector 40 from the value γ supplied from the operation unit 41.
_The value δ is obtained by subtracting _i-1 . The operation unit 43 is an operation unit 4
The value δ supplied from 2 is subtracted from 1 to obtain the value β. The value β of the calculation unit 43 is supplied to the selector 37. Other configurations are the same as those in FIG.

[0038] Also in this embodiment, the i-th coefficient F × w _i-1 which is selected is supplied to the selector 37 by the selection unit 35, among the data supplied from the multiplier 32 ₀ to 32 _n-1, Only the i-th data is replaced by this data β and output.

FIG. 14 shows a fifth embodiment. In this embodiment, the value F selected by the selector 40 is
× wi _-1 is supplied to the arithmetic unit 51. The operation unit 5
1 is also supplied with a fade coefficient F from the memory 33. The arithmetic unit 51 subtracts F × wi ₋₁ from the fade coefficient F to obtain a value δ. The data δ output from the arithmetic unit 51 is supplied to the arithmetic unit 43, and the arithmetic unit 43 sets this value δ to 1
To obtain the value β. Other configurations are the same as those in FIG. That is, in this embodiment, data is calculated by calculating Equation (6).

(Equation 6) Thereby, the processing can be simplified.

Now, as shown in FIG. 15, when executing fade-in and fade-out using a cube (w ₁ ) as a base image, as shown in FIG. 15, since the coefficient w ₀ is always 0, the coefficients W ₀ and W _The coefficient W ₁ obtained from ₂ has such a characteristic that the coefficient W ₂ is inverted with reference to 0.5.

When an animation is created based on these characteristics, FIGS. 16A to 16F and FIG.
To (k). That is, a quadrangular pyramid component is added to the cube including the cube, and the cube returns to the cube again. After that, the components of the quadrangular pyramid are added again, and the cube returns to a cube.

FIG. 18 shows the configuration of the sixth embodiment. In this embodiment, the pattern selection signal S is stored in the memory 61. The pattern selection signal S is a binary signal of logic 1 or 0. The pattern selection signal S is supplied to the selector 62 and the selector 64.
The selector 62 and 64 are also supplied with a selection signal from the selector 63. The selector 63 selects the i-th data (F × w _i−1 ) when the pattern selection signal S is 1, and selects the j-th value (F × w _j−1 ) when S = 0. The selector 62 is controlled. That is, the selector 62 removes the i-th value when the pattern selection signal S is 1, and j when S = 0.
The third value is removed, and the other values are output to the calculation unit 36. The operation unit 36 adds the input values, subtracts the added value from 1, obtains β, and outputs β to the selector 64. Further to the selector 64 is also supplied the output of the multiplier 32 ₀ to 32 _n-1. Further, the output of the selector 63 is also supplied to the selector 64. When the pattern selection signal S is 1, the i-th value is replaced by β, and when the S is 0, the j-th value is output. Is replaced by β and output.

As a result, when S = 1, the shape pattern P
_{For 0} , W ₀ (= F × w ₀ ) is used as a weighting coefficient,
For the shape pattern P _i−1 , W _i−1 (= β) is used as a weighting coefficient, and for the shape pattern P _n−1 , W _n−1 (= F)
× w _n-1 ) is used as a weighting coefficient. Further, in the case of S = 0 it is, W ₀ (= F × for shape pattern P ₀
w ₀ ), W _j−1 (= β) for P _j−1 , and P _n−1
, W _n-1 (= F × w _n-1 ) is adopted as a new weighting coefficient.

Further, when F = 1, w _{0 to} w _n−1 are directly used as weighting coefficients, and an animation with the original data is generated. When F = 0, W
_i-1 = 1 (or W _j-1 = 1), and all other weighting coefficients become 0, so that the base image P
A shape pattern of only _i-1 (or P _j-1 ) is obtained.

For example, if the fade coefficient F and the pattern selection signal S are set to a function as shown in FIG.
_{When 0} (F = 0, S = 1), there is only the base image P _i-1 . Between t ₁ and t ₂ , the animation remains the original data, and t = t ₃ (F = 0, S = 0)
In the case of, the shape pattern is only the base image P _j-1 . Then, in the section between t ₀ and t ₁ (S = 1), a shape pattern other than the base image P _i−1 is gradually added and faded in. Also, t _{2 to} t ₃ (S
= 0), the shape pattern other than the base image P _j-1 is gradually removed and faded out.
Therefore, an animation that starts with the base image P _i-1 and ends with the shape pattern P _j−1 is created.

As shown in FIG. 20, the fade coefficient F is 0
When the pattern selection signal S is switched in the course of linearly changing from (1) to (1) (when the fade coefficient is 0.5), the coefficient W _i-1 becomes β before and after that.
(1-F (1-w i-1)) from F × w _i-1 abruptly changes, the addition coefficient W _j-1 is F × w from _{j-1 β (1-F} (1-w
_j-1 )). For this reason, the generated shape pattern also changes rapidly.

Therefore, as shown in FIG. 21, when the fade coefficient F is 1 (when an animation with the original data is generated), the pattern selection signal S is switched from 1 to 0. This way,
The switching of the weighting coefficient corresponding to each shape pattern before and after the switching of the selection signal S is eliminated (the coefficient remains at wi _-1 before and after the switching), so that the base image can be switched without a break in the animation. become.

In the embodiment of FIG. 11, since there is no function of switching the shape pattern to be selected, different shape patterns cannot be used at the beginning and end of the scene.
On the other hand, in the embodiment shown in FIG. 18, the shape pattern to be selected can be switched, so that different shape patterns can be designated at the time of fade-in and fade-out. Therefore, an animation with a higher degree of freedom can be created.

The embodiment shown in FIG. 18 is further equivalent to FIG.
2 to 24 can also be used. FIG.
In the second embodiment, when the i-th and j-th are selected by the selection unit 72, the selection signal is supplied to the selector 71. The selector 71 is also supplied with a fade coefficient F from the memory 33. Selector 7
Numeral 1 has a fade coefficient determination function. After the fade coefficient F changes from 0 to 1, the coefficient to be removed is switched from i to j. Therefore, the pattern selection signal S in FIG. 18 becomes unnecessary.

Of the outputs of the multipliers 32 _{0 to} 32 _n−1 , i
The jth or jth output is removed, and the other output is supplied from the selector 71 to the calculator 36. The arithmetic unit 36 adds these inputs, subtracts the added value from 1 to obtain a value β, and supplies the value β to the selector 73. The selector 73 has a determination function similarly fade factor F a selector 71, when the F = 1, switch the i-th to j-th, of the supplied coefficient from the multiplier 32 ₀ to 32 _n-1, The i-th or j-th value specified by the selector 72 is replaced with the output β of the arithmetic unit 36 and output.

In the embodiment shown in FIG.
, A pattern selection signal S and i-th and j-th selection signals are supplied from a memory 61 and a selection unit 72. The selector 81 selects the i-th selection signal when the pattern selection signal S is 1, and selects the j-th selection signal when the pattern selection signal S is 0, and outputs it to the selector 34 and the selector 37. Therefore, in this embodiment, the selectors 34 and 37 of FIG. 11 can be used as they are.

In the embodiment shown in FIG.
Is supplied with a fade coefficient F from the memory 33. The selector 91 determines the magnitude of the fade coefficient F, and
Is not 1, the i-th selection signal supplied from the selection section 72 is selected, and when F becomes 1, the j-th selection signal is selected and output. The i-th or j-th selection signal from the selector 91 is supplied to the selector 34 and the selector 37. Therefore,
Selector also selects a predetermined one of the outputs of the multipliers 32 ₀ to 32 _n-1 In this case, as well as a selector for selecting a predetermined one of the output β of the multiplier 32 ₀ to 32 _n-1 and the arithmetic unit 36 , The same selector as in FIG. 11 can be used.

By using the embodiment of FIG. 18 to change the fade coefficient F for each of the weighting coefficients w ₀ , w ₁ , and w _{2 of} the sphere, cube, and quadrangular pyramid as shown in FIG. The weighting coefficients W _{0 to} W ₂ in consideration of F are shown in FIG.
It changes as shown in FIG. In this embodiment, fade-in is performed using the cube (w ₁ ) as a base image, and fade-out is performed using a quadrangular pyramid (w ₂ ) as a base image.

The coefficient w _{1 at} the time of fade-in and the coefficient w _{2 at} the time of fade-out are calculated as follows. W ₁ = 1−F × (w ₀ + w ₂ ) W ₂ = 1−F × (w ₀ + w ₁ )

The animation in this case is shown in FIG.
(A) to (f) and FIGS. 27 (g) to (k). That is, a cube is used as a base image, a quadrangular pyramid shape is added to the base image, and the cube is faded in to return to a cube again. Further, a quadrangular pyramid component is added from the cube and fade-out is performed, and the processing ends with a quadrangular pyramid base image.

In this animation, F × w ₀ =
Since it is 0 (constant), the effect of the sphere does not appear. Therefore,
In (a) to (c) (fade in), a quadrangular pyramid is gradually added to the cube (FIGS. 16 (a) to 16 (c)).
26 (d) to FIG. 27 (h), a normal animation (FIGS. 6 (d) to 7)
(Same as in (h)). Further, in FIGS. 27 (i) to 27 (k) (at fade-out), the cube is gradually removed and ends in a quadrangular pyramid. 26 (i) to (k) and FIGS. 7 (i) to 7 (k),
In the case of FIG. 26, the weighting coefficient of the quadrangular pyramid becomes larger earlier, so that the shape is closer to the quadrangular pyramid.

As described above, it is possible to create an animation that starts with an arbitrary shape pattern and ends with an arbitrary shape pattern using an existing animation.

[0058]

As described above, according to the animation image creating apparatus and the animation image creating method of the present invention ,
Since the weighting coefficient is multiplied by the fade coefficient and then multiplied by the image data, it is possible to easily realize an animation in which the beginning and end of the scene have the same predetermined shape pattern without complicated editing work. it can.

Further , the image data corresponding to the selected image data
Since the fade coefficient multiplied by the weighting multiplier is replaced with the replacement data, when creating an animation in which the beginning and end of the scene have the same shape pattern, the shape pattern can be selected as an arbitrary shape pattern. it can. Therefore, by switching the shape pattern to be selected, an animation having a different expression can be created while using the same part of the existing animation data.
