摘要:
A method is set forth for automatically adjusting screen and keypad brightness on a mobile electronic device having a light sensor, display screen and keypad, for optimum legibility under varying lighting conditions, with minimal eye strain and distraction. The method includes obtaining light level samples from the light sensor, and independently adjusting backlight intensity of the display screen and keypad responsive to the light level samples. Preferably, correct screen and keypad adjustments are made responsive to pulling the handheld device out of its holster notwithstanding non-optimal ambient light detection while the device is being removed from the holster. According to another aspect, the described method allows for ambient light detection in a handheld device where the light sensor and a message notification indicator share a common light pipe.

摘要:
A handheld communications device and method for transmitting an encryption key are provided. The method comprises: generating an encryption key via the data processor, the encryption key comprising a bit sequence; and varying an output of the display device over a period of time to transmit the encryption key from the handheld communications device by varying at least one of a sequence at least one of colour rendered on the display device or a sequence of brightness levels output by the display device.
摘要:
A handheld communications device comprises a display device, and a data processor that is in communication with the display device. The data processor is configured to generate an encryption key, and vary a visual output of the display device in accordance with a bit sequence of the encryption key. The varying visual output comprises a sequence of colors rendered on the display device and/or brightness levels output by the display device.
摘要:
A hot spot filter for a light guide is created by taking an image of the light output pattern of an illuminated light guide. The hot spot filter may be a film, a layer, or an additional liquid crystal display dedicated to attenuating bright spots from the light guide. The hot spot filter may be incorporated into the image display by adjusting the grey scale of individual pixels to provide sufficient compensation.

A mobile wireless communications device includes a housing and circuit board carried by the housing and includes radio frequency (RF) circuitry and a processor carried by the circuit board and operative with each other. A display connector for an LCD connector is mounted on the circuit board and adapted to be connected to a display. Display connection lines are carried by the circuit board and interconnect the display connector and processor for carrying signals from the processor to the display connector and a connected display. Filters are carried by the circuit board and connected to the display connection lines and reduce any interfering energy from the processor and display.
摘要:
A method of controlling a flash output for capturing an image in a portable electronic device having a digital camera includes receiving light at an image sensor, determining a flash output adjusted for colour and brightness based on the light received at the image sensor, providing the flash output, and capturing a resultant image at a digital image processor.
