Abstract: According to one embodiment, a control circuit includes a capacitive element connected between an output terminal of an output-switching transistor circuit and a control electrode, and a charge circuit charges the capacitive element when the ON/OFF switching signal is switched from an OFF command to an ON command, delay improvement circuit shortens a delay time from OFF to ON of the transistor circuit by setting the ON/OFF control voltage of the transistor circuit to the first switching threshold in conjunction with the operation of the charge circuit.

Abstract: A digital camera includes a CCD image sensor that produces a plurality of sets of image data by continuously capturing a subject, a controller that sets the priority for executing image processing on at least one of the plurality of sets of image data, and an image processor that subjects a plurality of sets of image data to image processing on the basis of the priority for executing image processing.

Abstract: An imaging device is provided that is configured to perform continuous shooting and includes an imaging unit, a memory, an imaging control unit and a grouping determination unit. The imaging unit is configured to capture an image of a subject. The memory is configured to store continuous shooting control information indicating a value of a control parameter related to continuous shooting. The imaging control unit is configured to cause the imaging unit to perform continuous shooting in accordance with the stored continuous shooting control information. The grouping determination unit is configured to determine, based on the stored continuous shooting control information, whether a series of image information are to be grouped together. The series of image information is obtained in one continuous shooting.

Abstract: An imaging device of the present invention includes a normal operation period and a focusing operation period and includes: a CCD (102) able to perform thinning processing on image signals of an imaging subject; an AFE (103) that converts the image signals into image data; a signal processing unit (104b) that converts the image data into display data; an LCD (107) that displays an image based on the display data; and a thinning control unit (104c) that that changes a read frame rate and thinning rate of the CCD (102). The thinning control unit (104c) performs control so that in the focusing operation period, image signals are read from the CCD (102) at a higher read frame rate than in the normal operation period, and so that in the focusing operation period and a frame immediately before the focusing operation period, image signals are read from the CCD (102) using a larger thinning rate than in the normal operation period.

Abstract: In a screw fluid machine including male and female rotors which are engaged with each other, a casing for accommodating both the male and female rotors, fluid working rooms which are formed by the male and female rotors and the casing, and fluid inlet and outlet ports which are provided in the casing so as to intercommunicate with one end portion and the other end portion of the working rooms, the helix angle of the screw gear constituting each of the male and female rotors is set to be continuously varied in a helix advance direction. Further, the screw gear is designed so that the peripheral length of a pitch cylinder in a helix advance direction on a development of a tooth-trace rolling curve on the pitch cylinder of the screw gear can be expressed by a substantially monotonically increasing function.
