Abstract: This document describes methods and systems for a hybrid white balance, HWB, mode (114), which is a hybrid of automatic and manual WB modes, in a camera system (104) of an electronic device (102). The HWB mode may provide options for a user to select a WB setting, via a camera user interface (118) in a live-preview mode (110), along a continuous WB-adjustment range. In this way, the user's desired color can be applied with respect to images or video captured by the camera system. The camera UI includes a manual WB control (112) to manually adjust the white balance. A WB module (108) determines target WB gains corresponding to the manual WB control relative to an initial automatic WB decision for a current frame displayed in the live-preview mode of the camera application. In aspects, a look-up-table correlating to the manual WB control is used to compute the target WB gains.

Abstract: This document describes techniques and apparatuses for automatic white-balance for a camera system. The techniques and apparatuses utilize a precursor image to detect one or more detected faces and determine a tone. The camera system retrieves tonal data based on a group of images determined to contain a same face as the detected face. Based on this tonal data, a difference in white balance is determined based on the difference in tone of the detected face within the precursor image and the associated tonal data. Camera settings are adjusted based on the difference in white balance to enable capture of an image having an improved tone.
