    Abstract: In an image pickup apparatus, a level compensator compensates the level of an image xL (i, j) sensed by an image sensor by exposure for a long time on the basis of the exposure of the image to produce a compensated image xL′ (i, j), while another level compensator compensates the level of an image xS (i, j) sensed by the image sensor by exposure for a short time on the basis of the exposure of the image to produce a compensated image xS′ (i, j). The image pickup apparatus also includes an image synthesizer to synthesize these compensates images xL′ (i, j) and xS′ (i, j) to produce a single synthetic image x (i, j). A dynamic range compressor also included in the image pickup apparatus compresses the synthetic image x (i, j) to produce a compressed image y (i, j) for delivery to outside.

    Abstract: An image signal generation portion 11 generates an image signal of a variable frame-rate picked-up image. A signal generation control portion 24 drives the image signal generation portion 11 and generates image pick-up setting information IF to generate an image signal that is frame-synchronized with a generated image signal DVd. The generated image signal DVd is output in condition where the image pick-up setting information IF is inserted in it. When supplied with image pick-up setting information IFex, the signal generation control portion 24 controls the driving operations of the image signal generation portion 11 based on the image pick-up setting information IFex, to frame-synchronize the generated image signal with an image signal of a reference variable frame-rate picked-up image of a source that has supplied the image pick-up setting information IFex. If a plurality of image pick-up devices capable of varying a frame rate is used, the image signals can be frame-synchronized with each other.

    Abstract: The present invention relates to an image processing circuit and an image processing method, and is applied to, for example, a video camera, an electronic still camera and the like, for compressing the dynamic range at a high compression rate with evading the lowering of an impression concerning the contrast and the unnatural edge emphasis. The present invention smoothes an input image X while preserving the edge to obtain a gain correction coefficient, and corrects the pixel value x(i, j) of the input image X with the gain correction coefficient.

    Abstract: A lever-type connector electrically detects a connected state of housings and has an improved reliability in its connection detecting function. A magnet (33) is provided integrally in an operable portion (31) of a lever (30), and a lead switch (50) is provided at the bottom surface of a receptacle (41). The lever (30) is operated to engage cam pins (44) with cam grooves (35), and female and male housings (10, 40) are properly connected by the cam action and the lead switch (50) is turned on by a magnetic force of the magnet (33). Whether the two housings (10, 40) are connected properly can be detected electrically by connecting the lead switch (50) with a detecting circuit or the like.

    Abstract: A rolling apparatus is disclosed which forms a thin walled portion on part of a steel strip by allowing the steel strip to intervene between a pair of upper and lower rolling rolls, in which the upper rolling roll is vertically movable. The steel strip which has been pressed between a pair of upper and lower rolling rolls is repeatedly moved on a traveling table to upstream side and downstream side alternately, thereby forming the thin walled portion having a width corresponding to the movement quantity. In forming the thin walled portion, the steel strip is grasped on both upstream side and downstream side with a plurality of clamping means and is subjected to a tension due to tension imparting means, thereby facilitating formation of the thin walled portion.
