Abstract: Provided are an imaging device and a focusing control method capable of preventing a focusing error even in a case where still image capturing is consecutively performed to enhance imaging quality. A digital camera performs a correlation operation of two images captured by a pixel pair P1 after performing an imaging process of an N-th frame, and determines a reliability of a correlation operation result based on the result of the correlation operation. In a case where the reliability is low, the digital camera performs a focusing control based on a contrast AF method in each time of imaging subsequent to an (N+1)-th frame, and in a case where the reliability is low, the digital camera performs a focusing control based on a phase difference AF method in an imaging process of the (N+1)-th frame.

Abstract translation: 提供了即使在连续执行静态图像拍摄以提高成像质量的情况下也能够防止聚焦误差的成像装置和聚焦控制方法。 在执行第N帧的成像处理之后，数字照相机执行由像素对P1拍摄的两个图像的相关运算，并且基于相关运算的结果来确定相关运算结果的可靠性。 在可靠性低的情况下，数字照相机在第（N + 1）帧之后的每次成像的时间都进行基于对比度AF方法的聚焦控制，并且在可靠性低的情况下， 数字照相机在第（N + 1）帧的成像处理中，基于相位差AF法进行聚焦控制。

Abstract: An information processing apparatus acquires a plurality of pieces of sound information, sound collection device position information, and target subject position information. In addition, the information processing apparatus specifies a target sound of a region corresponding to a position of a target subject from the plurality of pieces of sound information based on the acquired sound collection device position information and the acquired target subject position information. Further, the information processing apparatus generates target subject emphasis sound information indicating a sound including a target subject emphasis sound in which the specified target sound is emphasized more than a sound emitted from a region different from the region corresponding to the position of the target subject indicated by the acquired target subject position information in a case in which a virtual viewpoint video is generated.

Abstract: The image blur correction device includes an acceleration sensor, an angular velocity sensor, and a system control unit. The system control unit selects one of rotation axes based on a usage state of a digital camera, and calculates a shift blur amount generated in a direction by rotation of the digital camera around a second axis and a shift blur amount generated in a direction by rotation of the digital camera around a first axis based on distances from the selected rotation axis to the acceleration sensor, angular velocities, and accelerations.

Abstract: An image blur correction device includes an acceleration sensor, an angular velocity sensor, and a system control unit that calculates rotational acceleration components which are included in detected accelerations and are generated by rotation of a digital camera around a rotation axis parallel to an optical axis, and corrects blurs of the captured image signal in directions based on accelerations obtained by subtracting the rotational acceleration components from the accelerations detected by the acceleration sensor. The system control unit selects one of rotation axes based on a usage state of the digital camera, and calculates the rotational acceleration components generated by the rotation of the digital camera around the selected rotation axis based on an angular velocity and distances in the directions from the selected rotation axis to the acceleration sensor.

Abstract: In one aspect of the present invention, when reset of a camera is received, a pan motor and a tilt motor of a pan and tilt mechanism are rotated in a first preset rotation direction, and the pan and tilt mechanism is first moved to a pan reference position and a tilt reference position. Thereafter, the pan motor and the tilt motor are rotated in a second rotation direction opposite to the first rotation direction, and the pan and tilt mechanism is moved to an initial pan position and an initial tilt position. Using a movement of the pan and tilt mechanism to initial pan and tilt positions, detection of a subject for automatic tracking is performed, and if the subject is detected, then transition to an automatic tracking state is caused to occur.
