摘要： Torque ripples of a motor having interior permanent magnets can be reduced through the following method and the torque ripple controller using the same method: first, drive the motor having a plurality of phase windings and interior permanent magnets with a basic current supply circuit which outputs a basic current having a predetermined waveform, then store torque ripple waves produced in the running motor or obtained through a numerical analysis into a torque-ripple-wave-memory, next, compensate the torque ripple wave tapped off from the memory according to a prepared torque ripple compensation pattern and transform it to a torque compensation waveform with a torque-compensation-waveform-producing-circuit, further, multiply the torque compensation waveform tapped off from the waveform producing circuit by the basic current with a multiplier to output a torque ripple control current, and, supply the torque ripple control current to the plurality of phase windings shifting a phase by a predetermined electrical angle sequentially.

摘要： A normal AWB (auto white balance) correction value is calculated based on inputted image data. Further, a face area is identified from the inputted image data and a face AWB correction value is calculated based on image data in the face area. Then, first feature data and second feature data are extracted from the inputted image data and image data in the face area, respectively. A total AWB correction value is calculated in accordance with at least one of the face AWB correction value and the normal AWB correction value based on a comparison result of the first feature data and the second feature data. Thus, an erroneous correction can be prevented in an AWB correction using a face detection function.

摘要： When the image of a face is detected from within the image of a subject, the brightness of the face image is calculated. If it is determined that the face image is dark are requires a correction, a revised gamma correction curve is calculated in such a manner that both the face image and the overall image of the subject take on the appropriate brightness. A gamma correction is applied using the revised gamma correction curve. Noise reduction processing is executed in order to suppress the amount of noise produced by the gamma correction.

摘要： An image processing apparatus includes a face detector and a gamma corrector. The face detector detects a subject area or areas out of image data output from an image sensor. A correction table is produced on the basis of luminance values of the subject area and a frequency distribution of luminance, i.e., distribution information derived from the entire or part of an area represented by the image data. The gamma corrector uses either one of the above correction table and a basic correction table to correct the tone of the image data.

摘要： A motor includes a rotor with interior permanent magnets and a stator with teeth wound by concentrated windings. Each permanent magnet is split along a plane oriented towards the stator, and an electrically insulating section is set between the spilt magnet pieces. This structure allows each permanent magnet to be electrically split, thereby restraining the production of an eddy current. As a result, heat-production is dampened thereby preventing heat demagnetization of the permanent magnets.

摘要： In a stereoscopic imaging device including a plurality of imaging optical systems, a wide-image in which a principal subject is shifted from the center is taken, and also, a tele-image in which the principal subject is enlarged is taken at the same time. A size of a wide-side frame W, that is, a size of an angle of view of a trimming wide-image is decided based on a size of a tele-side frame T, that is, a zoom magnification of a tele-side imaging optical system, a position of the wide-side frame W displayed in the decided size is arbitrarily moved depending on an instruction from an operation unit, an area delimited by the wide-side frame W moved to any position is clipped from a default wide-image, and thereby, the trimming wide-image is obtained. Thereby, the tele-image which is a telephoto image in which a desired subject is zoomed, and the trimming wide-image which is a wide-angle image in which the subject can exist at a position other than the center of the image are simultaneously obtained.
