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: Provided are an imaging apparatus, an imaging method, and a program that can directly determine a sensor position at which an image with good image quality is obtained from obtained image information. The imaging apparatus moves an image sensor to a plurality of sensor positions in the optical axis direction of an imaging lens, and focuses a subject at each of the plurality of sensor positions. Image data of the subject focused at each of the plurality of sensor positions is acquired, and the image data is analyzed to calculate an image evaluation value at each of the plurality of sensor positions.

Abstract: Provided are an imaging device, an imaging device main body, and a focusing control method of an imaging device capable of appropriately supporting a photographer at the time of focusing. An image sensor movement driver that moves an image sensor along an optical axis is provided, and a subject is tracked by moving the image sensor within a movable range. A focusing operation detector that detects a focusing operation for the subject and a movable range switch that switches the movable range of the image sensor are provided. In a case where the focusing operation is detected by the focusing operation detector, the movable range switch widens the movable range of the image sensor.

Abstract: The present invention provides a focus device, an imaging system, and a method of outputting a focus-lens drive signal each capable of securing the amount of infrared rays incident on a focus sensor. Visible rays and infrared rays included in the incidence rays are transmitted through a first region of a diaphragm and the infrared rays are transmitted through a second region of the diaphragm. The visible rays are transmitted through a dichroic mirror, and are incident on an image sensor. The infrared rays are reflected by a reflection surface of the dichroic mirror, and are incident on a focus sensor. A focus-lens drive signal is output from the focus sensor, and is input to a focus-lens drive unit. A focus lens is driven by the focus-lens drive unit. The amount of rays incident on the focus sensor is not decreased, and hence precise focusing can be performed.

Abstract: There is provided a control device including a processor and a memory connected to or built into the processor. The processor acquires, for a marker of which a position in a vertical direction is variable with a displacement mechanism, the position of the marker in the vertical direction detected by an optical sensor mounted on a flying object and performs control of maintaining or changing a position of the flying object in the vertical direction, with respect to the flying object, based on the position of the marker in the vertical direction.
