The SDK that belongs to the Selfie 2.0 product family of popCamera SDK has been developed to solve the problems that occur under conflicting situations, such as “a selfie image taken with one hand is blurred” and “to take an unblurred image, you should use both hands, which is poor usability,” and achieve handier and higher-quality shooting of selfies and photos.
The following illustrates the positioning and relevance of the popCamera SDK products group of the SDK and the description scope of this document.
The SDK is a product that uses sensors mounted on a smartphone terminal to detect the movement of the terminal and determine quiescence/movement/vibration of the terminal so that the system can know the optimal timing of shutter release. SensorShutterCamera SDK provides the shooting function using the functions of SensorShutter, enabling users to easily develop apps. However, to develop a camera app that is more in line with the hardware, use this SDK.
SensorShutter provides two types of detection methods: flip shutter and tap shutter. Developers who use the SDK can select either of the shutter methods or enable both shutter methods for developing camera apps.
The FlipShutter and popShutter are, as these names indicate, methods of using the tap operation and flip operation of a smartphone instead of the shutter button on the screen. A smartphone equipped with these methods continuously monitors the quantity of motion measured with the speed sensor, acceleration sensor, and gyro sensor, and determines that the shutter is operated when movement in the opposite direction is detected immediately after the tilt or rotation movement is detected (moving of the terminal in any direction and returning of it to the original position).
Note that in this detection method, the same input information may be obtained as with the case of changing the way of holding a smartphone (correcting or changing the way of holding), leading to wrong detection of shutter operation. Therefore, for the SDK, the default threshold of the shutter determination is set to a higher value to prevent such wrong detection. Developers can specify the threshold for this determination as parameters.
The FlipShutter provided by the SDK can determine the flip operation in any of the X, Y, and Z directions as shutter.
or the conventional shutter by screen tap, the button coordinates on the screen are used in detection of tapping for shooting. On the other hand, the popShutter of the SDK can recognize tapping anywhere on either the front side (on the screen) or back side as shutter operation. This enables users to take selfies and photos by holding their smartphones in the desired way without being restricted by the arrangement of buttons on the screen.
