Abstract

It is an object of the present invention to enable to provide with a image display method which displays a high-quality picture without making any disorder on the screen even when the processing load increases.

A required time for each unit processing within one flame is detected during the image display processing, and a cumulative processing time Ta which is a total of each unit processing time is calculated. Then it is judged weather the situation Ta<Tr is made for the predetermined reference value Tr. By the result of the above judgement, the first display mode in which the pixel position of an odd number flame and an even number flame are differently arranged, and the second display mode in which the pixel position of an odd number flame and an even number flame are identically arranged, are alternatively settled. Then the paint processing for the object flame is performed. The first display mode which has advantage in picture quality is settled if the processing load is light. The second display mode is settled if the processing load is heavy. Accordingly, the disorder on the screen caused by the delay of processing is prevented and the high quality image display is realized.

Claims

1. An image displaying method for displaying an image by outputting image data by each flame to a display device, wherein being capable to set alternatively a first display mode which outputs image data to said display device with a different pixel arrangement for each flame and a second display mode which outputs image data to said display device with an identical pixel arrangement for each flame, comprising steps of:

judging a scale of a processing load performed within one flame, and

setting said first display mode when the load is judged to be light or setting said second display mode when the load is judged to be heavy.

2. An image displaying method according to

claim 1

, wherein said first display mode constitutes image data by arranging pixel data at different pixel positions each other for an odd number flame and an even number flame.

3. An image displaying method according to

claim 1

, further comprising steps of;

measuring a processing time required for the processing performed within one flame, and

judging a scale of a load by comparing said processing time with a predetermined reference value.

4. An image displaying method according to

claim 3

, wherein a switching operation to said first display mode is performed if said processing time is continuously less than said reference value during predetermined number of flames in the case where said second display mode is set.

5. A game system displaying an image by outputting image data to a display device for each flame, comprising a display mode setting device for setting alternatively a first display mode outputting image data to said display device with a different pixel arrangement for each flame and a second display mode outputting image data to said display device with an identical pixel arrangement for each flame, wherein said display mode setting device judges a scale of processing load performed within one flame, sets said first display mode when the load is judged to be light, or sets second display mode when the load is judged to be heavy.

6. A game system according to

claim 5

, wherein said display mode setting device makes said first display mode constitute image data by arranging pixel data at different pixel positions each other for an odd number flame and an even number flame.

7. A game system according to

claim 5

, wherein said display mode setting device measures a processing time required for the processing performed in one flame and judges a scale of load by comparing said processing time with a predetermined reference value.

8. A game system according to

claim 7

, wherein said display mode setting device sets a switching to said first display mode when said processing time is continuously less than said reference value during predetermined number of flames in the case where said second display mode is set.

9. A computer readable storage medium storing an image display program formed so as to make a computer, performing an image display processing to display an image by outputting image data to a display device by each flame, function as;

being able to set alternatively a first display mode which outputs image data to said display device with a different pixel arrangement for each flame to a second display mode which outputs image data to said display device with an identical pixel arrangement for each flame, and

judging a processing load performed within one flame and setting said first display mode when the load is judged to be light or setting said second display mode when the load is judged to be heavy.

10. A computer readable storage medium storing an image display program according to

claim 9

, wherein said first display mode constitutes image data by arranging pixel data at different pixel positions each other for an odd number flame and an even number flame.

11. A computer readable storage medium storing an image display program according to

claim 9

, wherein the program is formed so as to make the computer measure a processing time required for the processing performed in one flame and judge a scale of load by comparing said processing time with a predetermined reference value.

12. A computer readable storage medium storing an image display program according to

claim 11

, wherein the program is formed so as to make the computer switch to said first display mode when said processing time is continuously less than said reference value during predetermined number of flames in the case where said second display mode is set.
