Abstract: Provided are an image processing device capable of performing compression processing on a video captured in each video capturing mode according to a first video capturing mode and a second video capturing mode with different capturing conditions. A possible range of a quantization parameter applied in a case where the video is compressed is made different in the first video capturing mode and the second video capturing mode with different capturing conditions. The quantization parameter is determined within a first range in a case of the first video capturing mode, and the quantization parameter is determined within a second range narrower than the first range in a case of the second video capturing mode. In particular, a second upper limit value of the second range is smaller than a first upper limit value of the first range, and a second lower limit value of the second range is larger than a first lower limit value of the first range.

Abstract: A first imaging unit images angle-of-view mark light of each of other television cameras. An image compositing unit generates a virtual angle-of-view mark image and a virtual angle-of-view frame image as a virtual angle-of-view image showing an imaging angle of view of each of the other television cameras in an imaging angle of view of the host television camera based on the angle-of-view mark light of each of the other television cameras. The image compositing unit generates a composite image by compositing the virtual angle-of-view mark image and the virtual angle-of-view frame image with a video image. The composite image is displayed on a lens monitor of a lens device that is detachable from a camera body.

Abstract: A first imaging unit images subject light after angle-of-view mark light is removed by a dichroic mirror, and outputs a first imaging signal. A second imaging unit images the angle-of-view mark light of each of other television cameras. A calculating unit calculates a position of a virtual angle-of-view mark showing an imaging angle of view of each of the other television cameras in an imaging angle of view of the host television camera based on the angle-of-view mark light of each of the other television cameras. An image compositing unit generates a composite image by compositing a virtual angle-of-view mark image and a virtual angle-of-view frame image corresponding to the position of the virtual angle-of-view mark with a video image based on the first imaging signal. The composite image is displayed on a monitor.

Abstract: An imaging apparatus includes: a detection unit that detects accelerations in directions of three orthogonal axes; a generation unit that, in a case in which a difference between the magnitude of a resultant vector of the accelerations in the directions of the three orthogonal axes and the magnitude of the acceleration of gravity is equal to or less than a predetermined threshold value, generates a reference vector using the resultant vector; and a correction unit that corrects an image blur caused by translational shakes in directions of two orthogonal axes perpendicular to at least an optical axis of an imaging optical system, using the reference vector, on the basis of the accelerations in the directions of the three orthogonal axes.

Abstract: A control section 11 moves an imaging lens 1 based on a detection signal from an angular velocity detection section 6 so as to correct image blurring which occurs in captured image data obtained through imaging performed by an imaging element 3. The control section 11 calculates a first motion vector between first captured image data, which is obtained through imaging performed by the imaging element 3, and second captured image data which is obtained subsequent to the first captured image data and in which image blurring is corrected. The control section 11 performs an offset correction for reducing an offset signal included in the detection signal of the angular velocity detection section 6, based on the first motion vector.
