According to an aspect, there is provided an apparatus comprising at least one processor and at least one memory connected to the at least one processor. The at least one memory stores program instructions that, when executed by the at least one processor, cause the apparatus to determine based on at least one indicator that a camera connected to the apparatus is in a dark environment, initiate a calibration sequence of the camera in response to determining based on the at least one indicator that the camera connected to the apparatus is in a dark environment, capture, during the calibration sequence, multiple images with the camera with different sets of shooting parameters, cause analysis of the captured images to obtain camera calibration data, and store the camera calibration data in a memory of the apparatus.

Obtaining calibration data of a camera

In one example, digital image frames are accessed, each of the digital image frames having an associated control value for an automatic image capture processing function. A measure of information content change is determined for a current digital image frame relative to at least one previous digital image frame. A measure of information content reliability with respect to the automatic image capture processing function is determined for the current digital image frame. The control value associated with the current digital image frame is corrected based on the determined measure of information content change and the determined measure of information content reliability. A final control value for the automatic image capture processing function is output based on corrected control values for one or more digital image frames.

Adaptive output correction for digital image capture processing

A method including: displaying on a display a reference image; displaying on the display a start position within the reference image; displaying on the display an end position within the reference image; determining a trajectory between the start position and the end position; and defining a target image for each of a plurality of waypoints along the determined trajectory.

Image control method for defining images for waypoints along a trajectory

A device and a method for dynamically correcting camera module sensitivity variation using face data are disclosed. The method includes accessing a digital image frame of a scene where the digital image frame originates from a camera module. In response to detection of a face area in the digital image frame, a face chromaticity is calculated from the face area detected in the digital image frame by a processor. The method further includes determining a lighting condition at the scene associated with the digital image frame. Further, the method includes comparing the face chromaticity with a reference face chromaticity associated with the lighting condition to determine a chromaticity gain shift. Thereafter, the method includes correcting a gray point curve of the camera module based on the chromaticity gain shift to obtain a corrected gray point curve of the camera module.

Methods and devices for correction of camera module sensitivity and flash color variation

An apparatus including a processor configured to move automatically a sub-set of pixels defining a target captured image within a larger set of available pixels in a direction of an edge of the target captured image when a defined area of interest within the target captured image approaches the edge of the target captured image and configured to provide a pre-emptive user output when the sub-set of pixels approaches an edge of the set of available pixels.

Image capture

In accordance with an example embodiment of the present invention, a method comprises generating at least one modified image representation of a subject image representation using at least one color shading adjustment, calculating at least one frequency of color ratio values for each of the at least one modified image representation, and determining one of said at least one modified image representation and the subject image based at least in part on the at least one frequency.
