Abstract: A digital camera performs first predetermined image processing on digital image data representing a rectangular primary area in an object image acquired through photographing, and performs second predetermined image processing on digital image data representing secondary areas other than the primary area of the object image. The second image processing has an effect such that a compression rate for the secondary areas becomes higher than a compression rate for the primary area in the digital image data when the digital image data is compressed. After the digital image data subjected to these image processings has been compressed, the digital image data is recorded in a recording medium. In this manner, a data amount of the digital image data recorded through photographing can be effectively reduced.

Abstract: A worm is formed by rolling to reduce the number of processing steps while ensuring the worm accuracy satisfactorily. A work material is positioned between a first rolling die (100) and a second rolling die (101) by rotation of the rolling dies and a servomotor (76) for feeding the work material. When the lead angle of a worm is large and there is a large difference between the finished diameter and the blank diameter, the lead angle changes during the progress of rolling process, resulting in occurrence of through-feed. A slide plate (55) is freely slidable on a slide (53). Therefore, when through-feed occurs owing to the lead angles of the first and second rolling dies (100) and (101) and the workpiece, the slide plate (55) slides freely, and this is detected with a detecting sensor. The rotation of the first and second rolling dies (100) and (101) is stopped.

Abstract: A CCD is driven so as to output a video signal at a rate of one line out of four up to an enlargement ratio of 2×. If the enlargement ratio of 2× is surpassed, the CCD is controlled so as to output a video signal at a rate of one line out of two. Since resolution of the image represented by the video signal output from the CCD is raised, an image having a comparatively high resolution is obtained even when the image is enlarged by an electronic zoom function.
