摘要:
A highly-efficient standing-wave vibration motor is disclosed in which the rotating direction can be maintained when the driving frequency is in the vicinity of the resonant frequencies. Driving signals are applied to the motor via an inductance element. The inductance of the element is determined so that the phase difference between a phase of a bending vibration and a phase of a longitudinal vibration with respect to currents in relation to the respective driving voltages does not exceed .pi..

A vibration driven actuator includes a vibration member for causing an electro-mechanical energy conversion element to excite bending and longitudinal vibrations, and producing a driving force by using specific vibrations obtained by synthesizing the bending and longitudinal vibrations, and a projection portion formed at a position, on at least one of the energy conversion element and the vibration member, which corresponds to a node of the bending vibrations. The projection portion is used for supplying a signal to the energy conversion element.

A digital camera which performs digital processing on an image obtained by image capturing has a three-dimensional lattice point data table for image data conversion processing. The digital camera holds a matrix coefficient set for performing the conversion processing by matrix operation. In the respective lattice points of the three-dimensional lattice point data table, values corresponding to the conversion processing with the matrix coefficient set are set. Then a raw image file, including compressed image data obtained by lossy compression on the image data converted by the conversion processing and the held matrix coefficient set, as attendant information, is generated.

An image pickup system causes a first illumination unit to emit light toward a subject at a first angle without causing a second illumination unit for emitting light toward the subject at a second angle different from the first angle, and causes an image pickup unit to capture the image of the subject so as to obtain a first captured image. The image pickup system causes the second illumination unit to emit light without causing the first illumination unit to emit light, and causes the image pickup unit to capture the image of the subject so as to obtain a second captured image. The image pickup system associates the first captured image with the second captured image.

An image pickup apparatus including a photoelectric conversion element, first, a shutter speed for still-image pickup is set. Next, an image-pickup frame rate is set on the basis of the shutter speed for still-image pickup. Then, an operation of the photoelectric conversion element is controlled such that picked-up images are output at the set image-pickup frame rate. When the image-pickup frame rate that is set is higher than a moving-image-reproducing frame rate, a frame for use in a moving-image reproduction is generated from a plurality of frames of the picked-up images and reproduction is performed at the moving-image-reproduction frame rate.

An image sensing apparatus comprising: a CCD, optical system for forming an image on the CCD; A/D converter for converting an image signal outputted by the CCD to a digital signal; color interpolator for performing color interpolation on the digital signal converted by the A/D converter and generating image data on R, G and B color planes; color space converter for converting RGB color space to YUV colorimetric system; and median filter for reducing pseudo color components, generated by the color interpolator, by controlling color difference signals U and V. By cutting high frequency components of the signal, filtered by the median filter, then thinning out YUV signals and performing JPEG compression, pseudo color components generated by color interpolation can be reduced.

摘要:
A sensor includes a plurality of weight portions which swivel, support parts each of which supports at one end a corresponding one of the plurality of weight portions in the same direction, and a driving part which supplies driving power to the support parts to swivel the plurality of weight portions. The driving part swivels at least one weight portion of the plurality of weight portions in a first direction and a remaining weight portion in a second direction opposite to the first direction so that the angular velocity about an axis parallel to a predetermined swivel locus of the at least one weight portion, excluding an acceleration component in the direction of the axis, can be detected from the difference between a deviation of a swivel locus of the at least one weight portion from the predetermined swivel locus and a deviation of a swivel locus of the remaining weight portion from a predetermined swivel locus thereof.

An information processing apparatus includes a first acquisition unit configured to acquire a first image generated based on light passing through a lens unit, a second acquisition unit configured to acquire information corresponding to a pupil distance of the lens unit when the first image is acquired, and a correction unit configured to generate a second image, which is generated by correcting optical characteristics of the lens unit based on a position of the lens unit at the time of acquisition of the first image, wherein the correction unit corrects the first image affected by the optical characteristics based on the lens position of the lens unit based on the information corresponding to the pupil distance acquired by the second acquisition unit.
摘要:
A lens unit 1 acquires identification information for an attached lens unit from the lens unit and stores the acquired identification information in a second memory 37. In a case in which correction information for the stored identification information is not registered, a CPU 36 reads the correction information for the stored identification information out from an external memory 39 and registers it.
