An electronic device, method and computer program product enable an enhanced user experience by adjusting a white balance of a display device according to user preferences in combination with automatically adjusting luminance and chromaticity in response to ambient light conditions. The electronic device includes a color-sensitive ambient light sensor (ALS) and the display device. A controller of the electronic device measures luminance and chromaticity of ambient light using the ALS. The controller adjusts display brightness of the display device in relation to intensity of the luminance of the ambient light. The controller automatically determines a display target correlated color temperature (CCT) in relation to the chromaticity of the ambient light. The controller determines a display target white balance CCT adjusted in relation to user selection(s) related to white balance. The controller sets the display device to digitally map colors about a neutral color defined by the display target white balance.

Automatic white balancing of display device to match user-preferred modes

A device includes a digital camera positioned underneath a display of the device that captures images through the display. When capturing images using the digital camera, light emitted by the display can get into the digital camera, interfering with or corrupting the captured images. Calibration images are displayed on the display and captured by the digital camera to be used to generate an enhanced output image that mitigates the interference from the display. Recalibration images are subsequently captured in response to any of a variety of different trigger events that may cause or indicate a change in the alignment and geometries of the display pixels to the imager pixels. The captured recalibration image is merged with the previously captured calibration image to generate a merged calibration image, which is afterwards used as the captured calibration image.

Generating calibration images by merging captured recalibration images with previously captured calibration images

A device includes a digital camera positioned underneath a display of the device that captures images through the display. When capturing images using the digital camera, light emitted by the display can get into the digital camera, interfering with or corrupting the captured images. An enhanced output image is generated from a captured image that mitigates the interference from the display. The enhanced output image is generated, for example, by capturing a different calibration image for each pixel type (e.g., Red, Green, and Blue) included in the display. When an image is subsequently captured, an amount of color emitted by the pixels on the display for the currently displayed image is determined and one or more subtraction images are generated and subtracted from the captured image to mitigate the interference from the display.

Mitigating display interference with captured image using calibration images

A device includes a digital camera positioned underneath a display of the device that captures images through the display. The brightness of the display is controlled when capturing images using the digital camera to reduce interference from light emitted by the display with the captured images. The brightness can be controlled in various manners, such as reducing the brightness of only a camera region of the display that is within the field of view of the camera, reducing the brightness of only an expanded region of the display that includes a camera region of the display and an area surrounding the camera region but less than the entire display, reducing the brightness of the entire display or the brightness of only particular colors of the display, blacking out the camera region of the display, blacking out the expanded region of the display, strobing the display, and so forth.
