Abstract

An information processing device communicably connected to a head mounted display including a display device displaying an image and a sight line detector detecting a user'"'"'s line of sight is caused to function as a drawing control part. The drawing control part controls drawing of the image such that the drawing is simplified in a peripheral region of a user'"'"'s gaze point as compared to a vicinity region of the gaze point based on information on the user'"'"'s line of sight detected by the sight line detector.

Claims

1. An image processing method executed by an information processing device communicably connected to a head mounted display comprising a display device configured to display an image and a sight line detector configured to detect a user'"'"'s line of sight, the image processing method comprising:

controlling drawing of the image such that the drawing is simplified in a peripheral region of a gaze point of the user as compared to a vicinity region that is nearer to the gaze point than the peripheral region, based on information of the user'"'"'s line of sight detected by the sight line detector.

2. The image processing method according to claim 1, further comprising:

storing a plurality of models drawn at different levels of image quality for each type of the model,

wherein the controlling drawing of the image comprises

switching the model located in the peripheral region to the model with lower image quality as compared to the model located in the vicinity region.

3. The image processing method according to claim 2,

wherein the controlling drawing of the image comprises

switching the model located in the vicinity region to the model with highest image quality out of corresponding type of the models stored.

4. The image processing method according to claim 2,

wherein the storing a plurality of models comprises

storing a plurality of models having different levels of polygon count for each type of the model,

wherein the controlling drawing of the image comprises

switching the model located in the peripheral region to the model having smaller polygon count as compared to the model located in the vicinity region.

5. The image processing method according to claim 2,

wherein the storing a plurality of models comprises

storing a plurality of models having different levels of texture resolution for each type of the model,

wherein the controlling drawing of the image comprises

switching the model located in the peripheral region to the model having lower texture resolution as compared to the model located in the vicinity region.

6. The image processing method according to claim 2,

wherein the storing a plurality of models comprises

storing a plurality of models having different degrees of shader effect for each type of the model,

wherein the controlling drawing of the image comprises

switching the model located in the peripheral region to the model having smaller degree of shader effect as compared to the model located in the vicinity region.

7. A non-transitory recording medium readable by an information processing device communicably connected to a head mounted display comprising a display device configured to display an image and a sight line detector configured to detect a user'"'"'s line of sight, the recording medium storing a program causing the information processing device to function as:

a drawing control part that controls drawing of the image such that the drawing is simplified in a peripheral region of a gaze point of the user as compared to a vicinity region that is nearer to the gaze point than the peripheral region, based on information of the user'"'"'s line of sight detected by the sight line detector.

8. The recording medium according to claim 7, the program further causing the information processing device to function as:

a storage part that stores a plurality of models drawn at different levels of image quality for each type of the model,

wherein the drawing control part switches the model located in the peripheral region to the model with lower image quality as compared to the model located in the vicinity region.

9. The recording medium according to claim 8,

wherein the drawing control part switches the model located in the vicinity region to the model with highest image quality out of corresponding type of the models stored in the storage part.

10. The recording medium according to claim 8,

wherein the storage part stores a plurality of models having different levels of polygon count for each type of the model,

wherein the drawing control part switches the model located in the peripheral region to the model having smaller polygon count as compared to the model located in the vicinity region.

11. The recording medium according to claim 8,

wherein the storage part stores a plurality of models having different levels of texture resolution for each type of the model,

wherein the drawing control part switches the model located in the peripheral region to the model having lower texture resolution as compared to the model located in the vicinity region.

12. The recording medium according to claim 8,

wherein the storage part stores a plurality of models having different degrees of shader effect for each type of the model,

wherein the drawing control part switches the model located in the peripheral region to the model having smaller degree of shader effect as compared to the model located in the vicinity region.
