Simulate how the landscape will look when snow falls. In such a landscape simulation, it is preferable that the result of the simulation is close to the actual phenomenon, so that reality is required.

[0003] Conventionally, as a landscape image generating apparatus for performing a landscape simulation, for example, there has been a device that generates a specific landscape image displaying a landscape in a state of snowfall based on a landscape image displaying a landscape. In this method, a specific landscape image is generated by superimposing an image of a snow landscape different from the landscape on a landscape image displaying a certain landscape.

[0004]

However, in the conventional landscape image generating apparatus, since the image of the snow scene is simply superimposed on the original landscape image, the generated specific landscape image is not included in the landscape image. As unnatural and lacked reality.

Then, when the detected color density satisfies a predetermined condition, the image processing means performs predetermined image processing on the image area. When a specific landscape image is generated by processing the landscape image in this way, the specific landscape image is output by the output unit.

Here, the density detecting means targets at least one image region constituting the landscape image, and this image region is, for example, all or a part (minimum of one pixel) of the landscape image. The detection result may be, for example, the color density of each pixel in the image area, the color density of each predetermined number of pixels in the predetermined area, or the color density of the entire predetermined area. Alternatively, the color density of a plurality of pixels randomly extracted in a predetermined area may be used.

The image processing means performs a predetermined image processing on the image area. The predetermined image processing includes, for example, a case where a specific landscape image in a state where snow falls is accumulated. In the image area, there is a process of replacing the color of a pixel whose color density exceeds a predetermined value with white, and, for example, when generating a specific landscape image in a rainy state, in the image area, For some pixels around the pixel whose density exceeds a predetermined value, blurring or the like may be performed such that the pixel becomes wet with water.

The density detecting means and the image processing means detect the color density in the image area of the landscape image and perform image processing according to the degree. In addition to this, the hue and color The degree, the luminance, and the like may be detected, and the image processing may be performed according to the degree.

The output means may be, for example, a display means such as a CRT, a printing means such as a printer, an information writing means such as an FDD, or a communication means such as a modem. It may be a process for outputting an image.

In the first aspect of the present invention, "specific conditions" means, for example, a state of snow or rain, a state of snow, a cloudy or foggy state, or a clear state. . That is, the landscape image generating device according to the present invention uses a landscape image displaying a certain landscape, when it is snowing or raining, when it is snowing, when it is cloudy or foggy, or when it is sunny, etc. It simulates what the landscape looks like.

The CRTC 150 is connected to a CRT 190 for displaying an output image signal on a screen.
The C150 reads the display data stored in the VRAM 135 sequentially from the head address at a predetermined cycle, converts the read display data into an image signal, and
Output.

The CPU 110 includes a microprocessing unit MPU and the like. When a specific landscape image is generated, the CPU 110 activates a predetermined program stored in a predetermined area of the ROM 120 and executes the processing shown in the flowchart of FIG. It has become. FIG.
5 is a flowchart showing a process executed by the control unit.

First, in FIG. 2, for example, when an instruction to generate a specific landscape image is input from the keyboard 180, the process proceeds to step S100, where the landscape image data is input to the scanner 1.
60, the process proceeds to step S102, for example, the color density of each pixel is detected in a predetermined order from the upper left of the landscape image related to the landscape image data, and the process proceeds to step S10.
Then, it is determined whether or not the detected color density exceeds a predetermined value. This predetermined value is set for each object (for example, leaf, tree, mountain,
For example, if the object is a leaf, the color density at the center of the leaf is set to a predetermined value. Each object is specified by the hue of a pixel whose color density is to be detected, the hue of surrounding pixels, and the like.

When it is determined in step S104 that the detected color density exceeds a predetermined value (Yes).
Proceeds to step S106, replaces the color of the corresponding pixel with white, and proceeds to step S108 to execute steps S102 to S102 for all the pixels in the landscape image.
It is determined whether or not the process of step S106 has been completed. If it is determined that the process has been completed (Yes), the process proceeds to step S1.
The process moves to 10.

In step S110, step S102

Next, the operation of the above embodiment will be described.
First, when a specific landscape image is generated, the fact is input using the keyboard 180 and a landscape image from which the specific landscape image is generated is read from the scanner 160. Then, in step S100, the landscape image data of the landscape image is read into the RAM. At this time, the landscape image data is input as, for example, 800 × 600 pixel full color image data.

Next, in step S102, for example, the color density of each pixel is detected in order from left to right and from top to bottom with reference to the upper left of the landscape image related to the landscape image data. If the detected color density is higher than the predetermined value, the color of the corresponding pixel is replaced with white in step S106. If the detected color density is lower than the predetermined value, No image processing is performed on the pixels. For example, as for a leaf, the color density at the center of the leaf is set to a predetermined value, so that the color of the light part that is just illuminated is replaced with white, and the color of the dark part that becomes a shadow remains unchanged .

After the processing has been completed for all the pixels as described above, in steps S110 and S112,
The specific landscape image data that is the processing result is stored in the auxiliary storage device 170, and the specific landscape image data is stored in C

I can draw snow, compared to the past,
It is possible to generate a specific landscape image displaying a landscape in a state where snow falls and relatively approximate to a real phenomenon.

Further, since a predetermined value of the color density is set for each object included in the landscape image, snow can be drawn according to the subtle shade of each object, and the landscape in a state where snow falls and is accumulated is displayed. The generated specific landscape image can be generated by further approximating the actual phenomenon.

However, the present invention is not limited to this, and the present invention is not limited to this. It may be configured to generate a specific landscape image that displays a landscape in a sunken state or a clear state. For example, when generating a specific landscape image displaying a landscape in a rainy state, some pixels around the pixel around which the color density exceeds a predetermined value are in a state of being wet with water. By performing image processing such as blurring, a light portion which is actually hit by rain becomes wet, and a dark portion which is shaded by rain is left as it is.

In the above embodiment, the color of a pixel having a color density higher than a predetermined value is simply replaced with white. However, the present invention is not limited to this. May be configured to decrease the saturation of the color. With such a configuration, the background color appears to some extent even in a place where snow falls, so that the specific landscape image can be generated by further approximating the actual phenomenon.

Further, in the above embodiment, the color density of the pixel is detected and the image processing is performed according to the degree. However, the present invention is not limited to this, and the hue, the saturation, the luminance and the like are detected. The image processing may be performed according to the degree. With such a configuration, the specific landscape image can be generated by further approximating the actual phenomenon.

Further, in the above embodiment, steps S102 to S102 are performed for all the pixels in the landscape image.
Although the processing of S106 is configured to be performed, the invention is not limited thereto, and the processing of steps S102 to S106 may be performed for some pixels extracted at random. With such a configuration, the specific landscape image can be generated by further approximating the actual phenomenon.

Further, in the above-described embodiment, the case where a program stored in the ROM 120 is executed in executing the processing shown in the flowchart of FIG. 2 has been described. However, the present invention is not limited to this. The program may be read from the recording medium on which the program indicating the procedure is recorded into the RAM 130 and executed.
