Abstract: The present disclosure relates to an arithmetic device that reduces a scale of an arithmetic processing unit which performs an arithmetic process between frames in a sensor. A frame memory stores pixel data of a frame that transitions in time sequence. An inter-frame arithmetic processing unit implements a predetermined arithmetic by column parallel in a row unit on the pixel data of a current frame and the pixel data of a past frame stored in the frame memory and updates the pixel data of the past frame stored in the frame memory on the basis of a result of the predetermined arithmetic.

Abstract: An object of the present invention is to provide a device that is capable of presenting image information that is larger than an object by irradiating light onto the object that moves on a trajectory that is not known. An object tracking section controls line of sight direction so as to be directed towards a moving object. A rendering section irradiates a light beam in a direction along the line of sight direction. In this way the rendering section can irradiate the light beam onto the surface of the object. It is possible to present information, that has been rendered in a range that is larger than the surface area of the object, to an observer, utilizing an after image of the light beam that has been irradiated on the surface of the object.

Abstract: Example systems described herein to perform downhole fluid analysis include a depressurizer to be positioned downhole in a geological formation to depressurize a formation fluid in the geological formation. In such example systems, the depressurization of the formation fluid is to cause bubbles to nucleate in the formation fluid. Such example systems also include an imaging processor to be positioned downhole in the geological formation. In such example systems, the imaging processor is to capture imaging data associated with the formation fluid and to detect nucleation of the bubbles in the formation fluid based on the imaging data. Such example systems further include a controller to report measurement data via a telemetry communication link to a receiver to be located outside the geological formation. In such example systems, the measurement data includes a bubble point of the formation fluid calculated based on the detected nucleation of the bubbles.

Abstract: An object of the present invention is to widen a range in which line of sight change is possible, particularly in a pan direction. According to the present invention it is possible to acquire high line of sight changing speed. A pan mirror is capable of rotation in forward and reverse directions about a third rotational axis. Also, the third rotational axis extends in a direction that is substantially parallel to a line of sight direction directed from a tilt direction control section to the pan mirror. An angle α formed by the pan mirror and the third rotational axis is set in a range 0°
