Description

  The present invention relates to an image processing apparatus and an image processing method for processing movement of an image displayed on a display unit.

  In recent years, many portable terminals include a small LCD (Liquid Crystal Display) as a display unit and display objects such as characters and images on the LCD. And in order to use a small display part effectively, many portable terminals align so that the space between objects becomes as small as possible, and display a lot of information on a narrow screen. Yes.

  Conventionally, there is a method using an intermediate color as a technique for aligning an object with an accuracy of 1 pixel or less. An alignment method using intermediate colors will be described with reference to FIG. FIG. 11A shows a bitmap font of characters “Kanji”. When this bitmap font is moved to the right of the 1/3 pixel drawing, for example, the original bitmap font is enlarged three times in the vertical and horizontal directions as shown in FIG. The bitmap font thus moved is moved to the right in the 1-pixel drawing. Then, the average of the color values of three vertical pixels and three horizontal pixels, that is, nine pixels is obtained, and the enlarged font is reduced to 1/3. FIG.11 (d) is an enlarged view of FIG.11 (c). FIG. 11D shows that the bitmap font has moved by 1/3 pixel.

  Further, in the conventional bitmap font, a white space provided around the character is provided as an option. The left side bearing (or right side bearing), which is a sub-pixel included in this white space, is converted to a luminance value (luminance) of sub-pixel RGB, and rendering is performed in sub-pixel units in a bitmap font based on this luminance value. And a technique for performing hinting (for example, Patent Document 1).

  However, the method of aligning an object using an intermediate color has a problem that the edge of an image is blurred and visibility is deteriorated because the color values of a plurality of pixels are averaged.

  In the technique described in Patent Document 1, each subpixel of RGB is treated as an independent light source (luminance value). However, when the width between objects is reduced, subpixel information to be emitted is lost. Unexpected color development may occur.

  The present invention has been made in view of the above-described problems, and provides an image processing apparatus and an image processing method that perform alignment with an accuracy of less than one pixel while preserving the color of an object such as a character or an image. The purpose is to provide.

  In order to achieve the above-described object, the present invention provides an image processing apparatus that processes movement of an object displayed on a display unit in which a plurality of pixels including a plurality of sub-pixels for generating different colors are arranged. The object is moved by moving at least a part of the color component values of the sub-pixels constituting the object corresponding to different colors in units of pixels.

  According to the present invention, an object is moved in units of subpixels by moving subpixels in units of pixels. When the sub-pixel is moved, the arrangement of the sub-pixels constituting the pixel is changed, but the number of light-emitting pixels and luminance are not changed, and the color is preserved. Further, the edge is preserved and the visibility is hardly deteriorated.

  Further, according to the present invention, it is possible to move the image with higher accuracy than the sub-pixel by moving a part of the color component value of the sub-pixel. At this time, there is no change in the sum of the color component values, and a sharp edge image can be obtained.

  An image processing apparatus to which the present invention is applied will be described below with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration of the image processing apparatus 1. The image processing apparatus 1 calculates an image input unit 2 that inputs an image to be moved, a movement amount input unit 3 that inputs an object movement distance and a movement direction, and a color component value movement distance for each RGB subpixel. And a movement processing unit 5 that moves the color component value for each RGB sub-pixel in units of one pixel according to the designated movement distance. The generated image of the image processing apparatus 1 is output to an output device 6 such as a display, a recording medium, or a network interface. The display is composed of a plurality of pixels. The pixel is composed of three subpixels arranged in the order of RGB. On the horizontal scanning line of the display, as shown in FIG. 2, subpixels are arranged in the order of RGBRGBRGB.

  The movement amount input unit 3 is an input device such as a pointing device or a keyboard. The movement amount input unit 3 receives an input of the movement distance and movement direction of the object. The moving distance input in the present embodiment has an accuracy of 1/3 pixel unit, for example.

The movement distance calculation unit 4 calculates the movement direction of the object based on the input to the movement amount input unit 3, and when the movement direction is the right direction of the drawing, the expression of the object is expressed by (Expression 1) to (Expression 3). The movement distances T _R , T _G , and T _B of the color component values for each RGB subpixel are calculated from the movement amount. Note (Equation 1) is a calculation formula for obtaining the moving distance T _R color component values of the sub-pixels R.
T _R = (N + 2) / 3 (Formula 1)
(Equation 2) is a calculation formula for calculating the moving distance T _G color component values of the sub-pixels G.
T _G = (N + 1) / 3 (Expression 2)
(Equation 3) is a calculation formula for calculating the moving distance T _B color component values of the subpixel B.
T _B = N / 3 (Formula 3)
However, in (Expression 1) to (Expression 3), the fractional part is rounded down.

From (Expression 1) to (Expression 3), when the moving distance of the object is 1/3 pixel, the moving distance TR of the color component value of the sub-pixel _R is 1 pixel, and the moving distance T of the color component value of the sub-pixel G. _G is 0 pixels, a moving distance T _B color component values of the sub-pixel B is calculated as 0-pixels.

When the moving distance of the object is 2/3 pixel, the moving distance TR of the color component value of the subpixel _R is 1 pixel and the moving color component value of the subpixel G is calculated from (Expression 1) to (Expression 3). the distance T _G is 1 pixel, the movement distance T _B color component values of the sub-pixel B is calculated as 0-pixels.

When the moving distance of the object is 1 pixel, the moving distance TR of the color component value of the sub-pixel _R is 1 pixel and the moving distance T of the color component value of the sub-pixel G from (Expression 1) to (Expression 3). _G is 1 pixel, the movement distance T _B color component values of the sub-pixel B is calculated as 1 pixel. This is the same as moving the entire object one pixel.

On the other hand, when the movement direction of the object is left movement, the movement amount calculation unit 4 uses (Expression 4) to (Expression 6) to move the color component value movement distances T _R and T _G for each RGB subpixel. , determine the _{T B.}

(Equation 4) is a calculation formula for obtaining the moving distance T _R color component values of the sub-pixels R.
T _R = N / 3 (Formula 4)
(Equation 5) is a calculation formula for calculating the moving distance T _G color component values of the sub-pixels G.
T _G = (N + 1) / 3 (Expression 5)
(Equation 6) is a calculation formula for calculating the moving distance T _B color component values of the subpixel B.
T _B = (N + 2) / 3 (Expression 6)
However, in (Expression 4) to (Expression 6), the fractional part is rounded down.

From (Expression 4) to (Expression 6), when the moving distance of the object is 1/3 pixel, the moving distance TR of the color component value of the sub-pixel _R is 0 pixel, and the moving distance T of the color component value of the sub-pixel G. _G is 0 pixels, a moving distance T _B color component values of the object B is calculated as 1 pixel.

When the moving distance of the object is 2/3 pixel, the moving distance TR of the color component value of the sub-pixel _R is 0 pixel and the moving color component value of the sub-pixel G from (Expression 4) to (Expression 6). The distance _TG is 1 pixel, and the moving distance TB of the color component value of the sub-pixel _B is 1 pixel.

When the moving distance of the object is 1 pixel, the moving distance TR of the color component value of the sub-pixel _R is 1 pixel and the moving distance T of the color component value of the sub-pixel G from (Expression 4) to (Expression 6). _G is 1 pixel, and the moving distance TB of the color component value of the sub-pixel _B is 1 pixel. This is the same as moving the entire object one pixel.

3 to 5 schematically show how the object is moved in the right direction. FIG. 3A shows a sub-pixel before movement. Before the movement, three sub-pixels arranged in the order of RGB constitute one pixel. FIG. 3B shows how the color component values of subpixels move. When the moving distance of the object is 1/3 pixel, as described above, the moving distance TR of the color component value of the sub-pixel _R is 1 pixel, the moving distance TG of the color component value of the sub-pixel _G is 0 pixel, The moving distance TB of the color component value of the pixel _B is 0 pixel. That is, when the moving distance of the object is 1/3 pixel, only the color component value of the subpixel R moves to the right by one pixel. Circle numbers in FIG. 3B indicate the order of movement. As shown in the figure, when moving the object in the right direction of the drawing, the processing is performed in order from the pixel at the right end of the object. The movement processing unit 5 performs a movement process for each horizontal line to move the entire object. FIG. 3C shows the arrangement of subpixels after movement. The subpixels after movement appear to be rearranged in the order of GBRGBR... That is, after movement, three subpixels conceptually arranged in the order of GBR constitute one pixel. The pixel before movement and the pixel after movement differ in the arrangement of subpixels, but the color component values of the RGB subpixels are not changed. For this reason, there is no change in the number of pixels that emit light and the luminance, and the color is preserved. Further, the edge is preserved and the visibility is hardly deteriorated.

Next, a state when the object is moved by 2/3 pixel is shown. FIG. 4A shows a sub-pixel before movement. Before the movement, three sub-pixels arranged in the order of RGB constitute one pixel. FIG. 4B shows how the color component values of subpixels move. When the moving distance of the object is 2/3 pixel, as described above, the moving distance TR of the color component value of the subpixel _R is 1 pixel, the moving distance TG of the color component value of the subpixel _G is 1 pixel, The moving distance TB of the color component value of the pixel _B is 0 pixel. That is, when the moving distance of the object is 2/3 pixel, the color component value of the subpixel R and the color component value of the subpixel G move to the right by one pixel. Circle numbers in FIG. 4B indicate the order of movement. As shown in the figure, when the object is moved in the right direction of the drawing, the moving process is performed in order from the pixel at the right end of the object.

  FIG. 4C shows the arrangement of subpixels after movement. The subpixels after the movement appear to have the color component values of the subpixels before the movement rearranged in the order of BRGBRG. That is, after the movement, conceptually, the three subpixels arranged in the order of BRG constitute one pixel. The pixel before movement and the pixel after movement differ in the arrangement of subpixels, but the color components of the RGB subpixels are not changed. For this reason, there is no change in the number of pixels that emit light and the luminance, and the color is preserved. Further, the edge is preserved and the visibility is hardly deteriorated.

Next, a state when the moving distance of the object is 1 pixel is shown. FIG. 5A shows a sub-pixel before movement. Before the movement, three sub-pixels arranged in the order of RGB constitute one pixel. FIG. 5B shows how the sub-pixel moves. When the moving distance of the object is 1 pixel, the moving distance TR of the color component value of the subpixel _R is 1 pixel, and the moving distance TG of the color component value of the subpixel _G is 1 pixel and the subpixel B as described above. the moving distance T _B of the color component value is 1 pixel. That is, when the movement amount of the object is 1 pixel, the color component values of all RGB sub-pixels are moved by 1 pixel. The circled numbers in FIG. 5B indicate the order of movement. As shown in the figure, when the object is moved in the right direction of the drawing, the moving process is sequentially performed from the pixel at the right end of the object.

  FIG. 5C shows the arrangement of subpixels after movement. Subpixels after movement are arranged in the order of RGBRGB. Even after the movement, the three subpixels arranged in the order of RGB constitute one pixel. When the object is moved by one pixel, the RGB arrangement does not change, and the entire pixel moves.

  As described above, the image processing apparatus 1 to which the present invention is applied moves the object in units of subpixels by moving the color component values of the subpixels in units of pixels. When the color component value of the sub-pixel is moved, the arrangement of the sub-pixels constituting the pixel changes, but the color is preserved with no change in the number of pixels that emit light and the luminance. Further, the edge is preserved and the visibility is hardly deteriorated.

  In addition, the process for moving the object to the right has been described so far. A process of moving the object to the left by 1/3 pixel will be described with reference to FIG. FIG. 6A shows a sub-pixel before movement. Before the movement, three sub-pixels arranged in the order of RGB constitute one pixel. FIG. 6B shows how the color component values of subpixels move. When the moving distance of the object is 1/3 pixel, only the color component value of the subpixel B moves by 1 pixel. Circle numbers in FIG. 6B indicate the order of movement. As shown in the figure, when the object is moved in the left direction of the drawing, the moving process is sequentially performed from the leftmost pixel of the object.

  FIG. 6C shows the arrangement of sub-pixels after movement. The subpixels after movement appear to be rearranged in the order of BRGBRG... That is, after the movement, conceptually, the three subpixels arranged in the order of BRG constitute one pixel.

  Similarly, when moving the object to the left by 2/3 pixel, the sub-pixels appear to have been rearranged as GBRGBR. That is, after the movement, conceptually, three subpixels arranged in the order of GBR constitute one pixel.

  Even when the object is moved to the left, the pixel before movement and the pixel after movement only differ in the arrangement of the subpixels, and the color components of the RGB subpixels constituting the pixel are not changed. For this reason, there is no change in the number of pixels that emit light and the luminance, and the color is preserved. Further, the edge is preserved and the visibility is hardly deteriorated.

  Next, another image processing apparatus 10 to which the present invention is applied will be described. The image processing apparatus 10 enables alignment with higher accuracy than a 1/3 pixel unit by moving a part of color component values of sub-pixels in a pixel unit. FIG. 7 is a block diagram illustrating a configuration of the image processing apparatus 10. The image processing apparatus 10 includes an image input unit 2 that inputs an image, a movement amount input unit 3 that inputs a movement distance and a movement direction of an object, and a movement rate calculation that calculates a movement rate of color component values of RGB sub-pixels. Unit 11, a color component value calculation unit 12 that calculates the color component value of the moved sub-pixel, and a movement processing unit 5 that moves the RGB sub-pixels according to the calculated color component value. The same components as those of the image processing apparatus 10 in FIG.

Moving the percentage calculation unit 11, the moving rate _W R color component values of each _sub-pixel, W G, and calculates the _{W B.}

With reference to the flowchart of FIG. 8, the moving ratio of the color component values of the sub-pixel W _R, W _G, the procedure of calculating the W _B will be described. In the following description, it is assumed that the moving distance of the object is n / D pixels (n and D are positive integers, n <D). Even if n / D exceeds 1 pixel, a movement exceeding 1 pixel can be dealt with by a normal movement process.

The movement ratio calculation unit 11 determines whether or not the movement distance n / D pixel of the object is 1/3 pixel or less (step S11). Here, when the moving distance n / D pixel of the object is 1/3 pixel or less (step S11; YES), the moving ratio calculation unit 11 sets the moving ratio WR of the color component value of the subpixel _R to 3n / D, the moving rate W _G color component values of the sub-pixels G 0, and 0 movement ratio W _B color component values of the sub-pixel B (step S12).

On the other hand, when the moving distance n / D pixel of the object is larger than 1/3 pixel (step S11; NO), the moving ratio calculation unit 11 determines whether the moving distance n / D pixel of the object is 2/3 pixel or less. (Step S13). Here, when the moving distance n / D object satisfies more than one-third and two-thirds or less (step S13; YES), the mobile ratio _{W R} color component values of the sub-pixels R 1 (i.e., total) the moving rate _{W G} color component values of the sub-pixels G 3n / D, the sub-pixel B move ratio _{W B} color component values to 0 (step S14).

On the other hand, when the moving distance n / D of the object is larger than 2/3 in step S13 (step S13; NO), the moving ratio calculation unit 11 sets the moving ratio WR of the color component value of the subpixel _R to 1, the moving rate _{W G} color component values of pixels G 1, the moving amount _{W B} of the color component values of the subpixel B with 3 × (n / D) (step S15).

  The color component value calculation unit 12 calculates the color component value of the subpixel after movement. When the object is moved to the right, the color component is calculated sequentially from the leftmost pixel to the rightmost pixel of the object. Conversely, when moving the object to the left, the processing is performed in order from the rightmost pixel of the object to the leftmost.

  A procedure for calculating the color component value of the sub-pixel after movement will be described with reference to the flowchart of FIG. In this flowchart, the following temporary variables are used and a sub-pixel for which a color component value is calculated is referred to as a target pixel.

x: horizontal position of the target subpixel y: height position of the target subpixel rem: moving color component value tmp: temporary storage of the moving color component value The color component value calculation unit 12 moves the color component value of the subpixel. Get the rate 3n / D. Then, 0 is substituted for the temporary variable y (step S21), and 0 is substituted for the temporary variable rem and the temporary variable x (step S22).

  The color component value calculation unit 12 substitutes (color component value in x, y) × (3n / D) into the temporary variable tmp (step S23). Then, (color component value at x, y) × (1-3n / D) + rem is calculated. This calculation result is defined as (color component value at x, y) (step S24). The (subcomponent value in x, y) calculated in step S24 is the target subpixel color component value after movement.

  Next, the color component value calculation unit 12 substitutes the value of the variable tmp for the variable rem (step S25). Then, the temporary variable x + 1 is calculated, and the calculated value is substituted for the temporary variable x (step S26).

  The color component value calculation unit 12 compares the temporary variable x with the width of the object. If the temporary variable x is smaller than the width of the object (step S27; NO), the processing of step S23 to step S26 is repeated. On the other hand, if the temporary variable x is equal to the width of the object (step S27; YES), the temporary variable y + 1 is calculated, and the calculated value is substituted into the temporary variable y (step S28).

  The color component value calculation unit 12 compares the temporary variable y with the height of the object. If the temporary variable y is smaller than the height of the object (step S29; NO), the processing of step S22 to step S28 is repeated. On the other hand, if the height of the object is equal to the temporary variable y (step S29; YES), the color component value calculation process is terminated.

  As a specific example, an operation when the moving distance of the object is 1/5 pixel and the moving direction is the right direction will be described. FIG. 10A shows a pixel before movement. In FIG. 10, three pixels are drawn. The color component values of the sub-pixels constituting these pixels are all 100.

When the movement of 1/5 pixel is instructed by the user, the movement amount calculation unit 11 proceeds to step S11 in FIG. 1/5 pixels, to meet the 1/5 ≦ 1/3, the movement amount calculating unit 11 goes to step S12, calculates the moving rate _{T R} color component values of the sub-pixels R. Moving ratio _{W R} becomes 3/5 (= 3 × 1 /5).

  The color component value calculation unit 12 inputs the movement ratio 3/5 of the subpixel R, and substitutes 0 for the temporary variable y, the temporary variable rem, and the temporary variable x. Then, a value obtained by multiplying the color component value of the sub-pixel R at the (0, 0) position (the rightmost pixel in FIG. 10) by the movement ratio 3/5 is substituted into the temporary variable tmp. At this time, the temporary variable tmp becomes 60.

  Then, the color component value calculation unit 12 multiplies the color component value of the sub-pixel R at the (0, 0) position by 2/3 (= 1-3 / 5), and further adds the temporary variable rem. The color component value of the sub-pixel R at the (0, 0) position is used. As a result, the color component value of the sub-pixel R at the (0, 0) position is 40.

  The color component value calculation unit 12 assigns the value of the temporary variable tmp to the temporary variable rem. Then, the color component value calculation unit 12 adds 1 to the temporary variable x. The color component value calculation unit 12 substitutes a value obtained by multiplying the color component value of the sub-pixel R at the (1, 0) position (the middle pixel in FIG. 10) by the movement ratio 3/5 into the temporary variable tmp. At this time, the temporary variable tmp becomes 60.

  Then, the color component value calculation unit 12 multiplies the color component value of the subpixel R at the (1, 0) position by 2/5, and further adds the temporary variable rem to the result at the (1,0) position. The color component value of the subpixel R is used. As a result, the color component value of the sub-pixel R at the (1, 0) position is 100.

  The color component value calculation unit 12 assigns the value of the temporary variable tmp to the temporary variable rem. Then, the color component value calculation unit 12 adds 1 to the temporary variable x. The color component value calculation unit 12 assigns a value obtained by multiplying the color component value of the sub-pixel R at the (2, 0) position (the leftmost pixel in FIG. 10) by the movement ratio 3/5 to the temporary variable tmp. At this time, the temporary variable temp becomes 60.

  Then, the color component value calculation unit 12 multiplies the color component value of the sub-pixel R at the (2, 0) position by 2/5, and further adds the temporary variable rem to the result at the (2, 0) position. The color component value of the subpixel R is used. As a result, the color component value of the sub-pixel R at the (2, 0) position is 100.

  The color component value calculation unit 12 assigns the value of the temporary variable tmp to the temporary variable rem. At this time, the value of the temporary variable tmp is 60. The color component value of the sub-pixel R at the (3, 0) position is 60.

  FIG. 10C shows the pixel after movement. The image processing apparatus 10 moves the color component value of the subpixel R by 60%, and sets the color component value of the subpixel R to 60, 100, 100, and 40. As shown in FIG. 10B, the image processing apparatus 10 moves 60% of the 1/3 pixel, that is, 1/5 pixel object by moving the color component value of the sub-pixel R by 60%. In the object moving methods described so far, the sum of the color component values does not change, and a sharper edge image can be obtained than the conventional method using intermediate colors.

  As described above, the image processing apparatus 10 according to the present embodiment moves part of the color components of the sub-pixels in units of pixels, and enables object alignment that is more accurate than 1/3 pixel. did.

  The example in which the object is moved rightward in the drawing has been described so far. Conversely, when the object is moved in the left direction of the drawing, the processing for the subpixel R in the movement ratio calculation processing shown in FIG. 8 and the color component value calculation processing shown in FIG. Replace.

  In addition, when the moving distance n / D of the object is 1 pixel or more, the moving process of 1 pixel or less may be performed after the amount exceeding 1 pixel is first processed by the normal movement.

  An image processing apparatus to which the present invention is applied is used, for example, for designing a GUI (Graphical User Interface) of a portable device. When a GUI designer arranges an object such as a character or an image on a screen, the GUI designer aligns the space between the object as much as possible and displays a large amount of information on a small display.

  The image processing apparatus may embed an image generated by executing an object moving process at the time of designing an image in a product, or may generate an image by executing the moving process at any time when displaying an image.

  In this embodiment, an example in which an object is moved along the horizontal axis of the display has been described. However, when subpixels are arranged in the vertical direction, the object can be moved along the vertical axis. . In a display that is rotated and used, the object is moved in accordance with the direction of the display.
