摘要： An image capture apparatus generating an image, a dynamic range of which is expanded by composing two images having different exposure amounts, includes an imaging unit which continuously outputs images captured to have two different exposure amounts. A system control unit of the image capture apparatus stores in a memory an image of the first frame of two frames to be composed, which are continuously output from the imaging unit, and composes an image of the second frame output from the imaging unit and the image held in the memory so as to expand a dynamic range. The system control unit generates tone compression characteristics based on the image held in the memory and an image obtained by reducing a resolution of the held image, and compresses tones of the composed image using the generated tone compression characteristics.

摘要： When sensing an image using an image sensor driven by the rolling shutter method, a shake of an image sensing apparatus in the exposure period of the image sensor is detected, and the temporal characteristic of the detected shake is obtained. For the temporal characteristic of the shake, the frequency distribution of the distortion amount of an object image that is generated in the image owing to the shake is analyzed. For at least the center frequency, the temporal characteristic of the shake is compensated for to eliminate a phase shift generated when the temporal characteristic of the shake is obtained. An object image distortion arising from the shake for each line of the image sensor is corrected using a correction amount calculated from the compensated temporal characteristic of the shake.

摘要： A centrifugal compressor for a turbo-fan engine includes a shroud covering the edges of vanes of a compressor wheel mounted on an outer shaft with a clearance &agr; left therebetween. A vertical section of the shroud includes an upstream portion extending in an axial direction, and a downstream portion curved radially outwards and extending from a downstream end of the upstream portion. The thickness of the downstream portion is increased gradually from the upstream side toward the downstream side. Thus, it is possible to prevent the variation of the clearance &agr; defined along the downstream portion of the shroud which exerts a large influence on the compression performance, thereby suppressing the reduction in performance due to the thermal expansion of the shroud.
