If the blinking display process is not selected, it is subsequently determined whether or not the color change display process is selected (S62). When the color change display process is selected, the write color change display layer is created by performing the color change display process of the write layer data (S65), and the process returns. If the color change display process is not selected, a writing layer data enhancement (line width enlargement) display process is created by performing writing layer data enhancement (line width enlargement) display processing (S62), and the process returns.

6). Layer (layer) concept and method for realizing layer screen composition processing
(A) Conceptual layers FIG. 7A and FIG. 7B show conceptual diagrams in which the original image layer and the writing layer are overlapped.
The original image layer is a layer for displaying the original image to be displayed and edited, and the writing layer is a layer for drawing the content written on the screen by the operator (100) by pen input or the like. These layers are subjected to screen composition processing, and the screen composition result (off-screen buffer) is transferred to constitute display contents. The original image data and the writing layer data are stored in the same folder, and the storage of the data may be realized by a bitmap method or a vector method.

The original image layer and the writing layer are associated with each other, and the associated writing layer is also switched in conjunction with the switching of the page of the original image. That is, the original image layer and the writing layer corresponding to the page are combined and displayed. Note that the number of writing layers associated with one original image layer is not limited to one, and a plurality of layers may be used.

(B) Method for realizing layer screen composition processing In FIG. 8, color information (color code) representation U in the writing layer, color information (color code) representation P in the original image layer, screen composition result (off-screen buffer) A color information (color code) expression O is shown in FIG. In the writing layer, the drawing method is determined in the T bit state. At this time, transparent / opaque can be selected for each dot (color specified by the operator).

In the screen composition result (off-screen buffer) in which the writing layer and the original image layer are combined, (a) an opaque color (T = 0) dot in the writing layer and (a) a transparent color (T = 1) in the writing layer ) And are shown separately. In (a), the “write” content is displayed over the page on the screen. In this case, for example, it feels like an overcoat with paint. In (A), as shown in FIG. 9, there are an implementation method (1) and an implementation method (2). In the realization method (1), red, green, and blue of color information (color code) in the writing layer (U) and the original image layer (P) are ANDed (logical product), respectively, and the screen composition result (O) and It is conceptually shown to be. In this case, there are the following effects, advantages and disadvantages.
Effect: A feeling of dyeing paper with a dye can be produced.
Pros: Processing is lighter than method (2).
Disadvantages: Depending on the color combination of the writing layer (U) and the layer (P) of the original image, no color may appear (the logical product pattern does not change).

In the realization method (2), red, green, and blue color information (color code) in the writing layer (U) and the original image layer (P) are respectively multiplied by the color components as shown in FIG. It is conceptually shown to be a synthesis result (O). In this case, there are the following effects, advantages and disadvantages.
Effect: A feeling of dyeing paper with a dye can be produced.
Pros: True to the expression of paper.
Cons: Processing is heavier than method (1). However, it can be easily realized by using MMX (multi-media processing instruction of x86 CPU such as Intel, USA, etc.) and RISC CPU having instructions equivalent to it.

FIG. 10 shows a flow of layer screen composition processing in the case of Red.
First, by multiplying the red value range of the color information in the writing layer (U) and the original image layer (P) by the color component shown in the figure, the range of the red value of the color information in the screen composition result (O) Will be required. In the case of Green and Blue, calculation may be performed similarly to Red.
