Method and System for Automatic Display Orientation Change to Accommodate Light Reflection

While capturing photograph on a mobile device , light reflecting directly onto the screen sometimes prevents the user from viewing the display. Thus, the user cannot view the photograph and determine whether it is satisfactory. The user must open the captured photograph to review it. Alternatively, the user can change the angle of capture to avoid light reflection, but that might not capture the desired image, either.

A method and system are needed by which a user can preview a captured photograph on a mobile device screen, even if there is a reflection of light.

Prior art does not discuss the identification of light reflected on a portion of the display . Current approaches to address the problem include changing the brightness of the portion of the display, dynamically calculating an effective display area and accordingly repositioning the content, or inclining the display to change the orientation. Prior art mentions making changes to the brightness level of the entire screen , but not a particular portion of the screen.

The novel contribution is a method and system to automatically change the mobile device display orientation to accommodate light reflection .

Software installed in mobile camera device analyzes the user's current usage behavior and additional illumination level on the screen to detect light reflection from the screen . Software analyzes the direction and area of reflection . The software then automatically changes the display orientation to reduce reflection and make the image visible to the user.

An illumination sensor installed in the display detects where the external light falls in the display, and then the software accordingly changes the brightness in the region . This helps the user view the content in the display, even if there is a reflected light in that portion of the screen.

The software can also adjust the display content where the actual picture content is displayed. When the sensor detects reflected light , the software installed in the display identifies the region and accordingly repositions the contents in the display . This improves the transparent display; the reflected portion automatically becomes transparent, so light passes through, which reduces the amount of reflected light. The display orientation automatically changes to avoid the...
