An imaging apparatus includes an image sensor and a processor that merges together a plurality of images captured by said image sensor to produce a composite image. The positions or the plurality of images being adjusted to reduce displacement of a reference area that is determined within each one of said plurality of images before the plurality of images is merged together. The reference area includes at least one of an in-focus area determined by a focusing operation, a face area determined by face-sensing processes, a predetermined-color area determined by white-balance information and predetermined color information, and a predetermined-brightness area determined by photometry.

A three-panel projection apparatus in which display quality due to displacements of fixing positions of panels is improved is provided. By displaying position-adjusting-images of a plurality of colors formed in a plurality of different patterns and by selecting any of the patterns, the overall display frame is compensated for with a method corresponding to the selected adjusting images and displayed. Further, at least two of the adjusting images are arranged on the opposing corners of the display frame. Still further, the compensating method performs computation on the basis of a target pixel and its circumferential pixels so as to form a compensation pixel.

The invention discloses a reciprocating compressor and a refrigerator with the same. The reciprocating compressor comprises a crankshaft, an air cylinder, a piston and an eccentric sleeve. The crankshaft comprises a main shaft and an eccentric shaft which are connected with each other and are eccentrically arranged, the piston is connected with the eccentric shaft through a connecting rod, the piston is arranged in the air cylinder and can move in the axial direction of the air cylinder, and an eccentric shaft sleeve is arranged on the eccentric shaft and located in a rod hole of the connecting rod; the eccentric shaft sleeve is located at the first position when the crankshaft rotates in the first direction, and is located at the second position when the crankshaft rotates in the second direction opposite to the first direction; when the eccentric shaft sleeve is located at the first position, the outer diameter center of the eccentric shaft sleeve is located on the side, far away from the main shaft, of the inner diameter center of the eccentric shaft sleeve; and when the eccentric shaft sleeve is located at the second position, the outer diameter center of the eccentric shaft sleeve is located on the side, close to the main shaft, of the inner diameter center of the eccentric shaft sleeve. The reciprocating compressor has different displacements when rotating in different directions, the displacement of the reciprocating compressor is adjustable, and the power dissipation is smaller.

A warm-up pilot pressure control unit adjusts pilot pressure inputted to a first flow channel open / close unit so that the flow channel open / close unit is switched to an open state when a warm-up start state is entered under the necessary condition that a first winch operation member is in a neutral position. When the first flow channel open / close unit is in the open state, a first pump displacement adjustment unit adjusts the displacement of a first hydraulic pump so that the differential pressure between a first pump hydraulic circuit and a first warm-up hydraulic circuit becomes constant at a predetermined set pressure.

The invention relates to a method and a device for applying an exciting force in a space direction, and belongs to the field of vibration testing, applying an exciting force and testing instruments. Move the vertical moving body and the horizontal moving and rotating block to an appropriate position, rotate the horizontal moving and rotating block at a certain angle, so that the angle between the axis of the pressure sensor and the horizontal direction is α, and then rotate the piezoelectric stack bracket by a certain amount. The angle β of , get the exciting force in X, Y, Z direction. The layout of the device is gantry type, the vertical moving body can move up and down along the vertical guide rail, the horizontal movement and the rotating block can rotate and move horizontally, the piezoelectric stack bracket can realize the rotation around the disc, and the piezoelectric stack is connected to the hinge by pushing The micro-motion platform realizes the output of displacement and force, and the displacement of the pressure sensor can be amplified by the long arm of the lever amplification mechanism. The advantages are stable structure, high excitation frequency, simple operation, adjustable output displacement, piezoelectric stacks of different lengths and specifications can be installed, and the object can be excited in all directions in space.
