Abstract: An improved mobile electronic device and camera provide an improved auto white balance system where constraints can be imposed the correlated color temperature (CCT) that is employed by the auto white balance system. For instance, if a distance between a subject and the camera is determined to exceed a threshold for closeness, the CCT can be constrained so that it is above a preset CCT that corresponds with sunrise or sunset. Other distance thresholds and the content of an image, as well as the brightness of the image, can be further employed in determining the CCT to employ.

Abstract: Various embodiments include devices, methods, circuits, data structures, and software that allow for rapid variation in the luminance of an OLED display panel. An OLED display driver circuit can include a first input, a second input, and a scaling circuit. The first input is to receive a scaling factor. The second input is to receive an image input signal including a digital representation of a desired output for a pixel. The scaling circuit is to multiply a pixel-level output voltage associated with the desired output for the pixel by the scaling factor.

Abstract: Applying quantum dots to surface features of an electronic device to augment or replace reflective and transmissive features. Applying quantum dots can yield more efficient illumination of those features and can permit use of diverse internal light sources to cause those features to emit any color of visible light. An electronic device, keyboard for same and method of applying features to areas of the exterior surface of an electronic device are provided. Quantum dots are applied to an area of the exterior surface that is illuminated by the device's internal light source. The quantum dots absorb incident light then emit predetermined longer wavelength light. The interior light may be a UV light, high energy light emitting diode, or back light. The quantum dots can be applied to exterior surfaces, buttons or key on electronic devices, mobile devices, and keyboards for mobile devices.

Abstract: A method and apparatus providing an autofocus routine in a camera apparatus having a processor is disclosed. The camera apparatus is adapted to detect a number of images and communicate image signals representative thereof to the processor. The method includes determining that a degree of change between a first image signal and a second image signal is below a predetermined threshold and responsive thereto, performing the autofocus routine.

Abstract: Systems and method to generate more readable modified images that are presented on electronic displays in bright ambient light, such as direct sunlight. Images normally presented in lower ambient light are modified to generate modified images that have higher contrast and that contain less information. For example, modified images contain pixels that are either “on” or “off” and may be inverted to present a black on white background image on the display. Some information, such as text fields or icons, is removed from the modified image to increase readability in bright ambient light. A backlight level of the display is also able to be increased in bright ambient light.

Abstract: A handheld communications device for transmitting an encryption key is provided. The device comprises a display device, and a data processor. The data processor of the handheld communications device is in communication with the display device. The data processor is configured to generate an encryption key, and to vary a visual output of the display device over time in accordance with a bit sequence of the encryption key. The varying visual output comprises a sequence of colors and/or brightness levels output by the display device.

Abstract: A method and an apparatus providing a visual indication of the occurrence of video recording operations on an electronic device. The video recording operations including recording a plurality of frames according to a number of characteristics. The method comprising providing a time interval between the recording of two consecutive frames by modifying at least one of the characteristics of the video recording operations and providing the visual indication of video recording operations during the time interval.
