Techniques for determining settings for a content capture device
摘要
說(shuō)明書
In some examples, a content capture device 1210 may be configured in a high dynamic range (HDR) mode. The HDR mode may facilitate capturing multiple images of a similar scene and stitching the multiple images together. In such examples, the HDR mode may include an ability to have one or more settings changed for particular images. In a traditional HDR mode, software and/or hardware associated with a content capture device may programmed to automatically adjust an exposure value (e.g., a number that represents a combination of a content capture device's shutter speed and f-number, sometimes abbreviated as EV) for a sequence of 3 or 5 frames by +/?1 EV or +/?1 EV and +/?3 EV. In some examples, EV may be an exposure step of a predetermined sized. For example, a 3-frame HDR mode may adjust the EV to ?1 for a first frame, 0 for a second frame, and +1 for a third frame. In such examples, the traditional HDR mode may blindly adjust exposure by a fixed amount in an attempt to increase contrast in an image. The object-based exposure methods described herein are able to provide proper settings for a number of objects in the image. For example, a 3-frame HDR mode may adjust the EV for a first object for a first frame, for a second object in a second frame, and for the remaining objects in a third frame.
