Abstract: Various examples pertaining to utilization of a resizer in image processing are described. A processor of an apparatus receives image data of a captured image from an image sensor. The processor processes the image data through a pipeline in which the image data is resized before further processing is performed to provide processed data of a processed image used in preview or video recording.

Abstract: A synchronization controller for a multi-sensor camera device includes a detection circuit and a control circuit. The detection circuit detects asynchronization between image outputs generated from the multi-sensor camera device, wherein the image outputs correspond to different viewing angles. The control circuit controls an operation of the multi-sensor camera device in response to the asynchronization detected by the detection circuit. In addition, a synchronization method applied to a multi-sensor camera device includes following steps: detecting asynchronization between image outputs generated from the multi-sensor camera device, wherein the image outputs correspond to different viewing angles; and controlling an operation of the multi-sensor camera device in response to the detected asynchronization.

Abstract: Techniques and examples pertaining to frame synchronization for dynamic frame rate in dual-camera applications are described. A change in brightness in ambient lighting may be detected when an electronic apparatus operates in a dual-camera mode utilizing images captured by a first image sensor and a second image sensor. In response to the detected change in brightness in the ambient lighting, frame rates of the first image sensor and the second image sensor may be synchronized.
