  • Patent number: 10450684
    Abstract: Disclosed is a sewing machine which evaluates sewing quality using a stitch tightness index. During sewing operation, a used length of an upper thread per stitch is detected, and a stitch tightness index per sewn stitch is calculated on the basis of a stitch length per stitch defined by sewing pattern data, a fabric thickness of a sewing workpiece, and detected data of the used length of the upper thread. Then, notification is made which corresponds to the calculated stitch tightness index per sewn stitch (such as a visual display of the stitch tightness index). After that, acceptability/non-acceptability of the thread tightness per sewn stitch can be determined by comparing the calculated stitch tightness index per sewn stitch against a reference value, and a result of the determination can be notified.

  • Patent number: 9609298
    Abstract: Disclosed herein are an imaging apparatus, an imaging method, a recording medium, and a program which are capable of processing imaging data in a manner similar to that of a normal frame rate. Image data captured by a solid-state imaging element capable of performing imaging at a high resolution and a high frame rate is supplied to a memory control. The memory control, at the same time as writing the imaging data input from the imaging element in a frame memory, reads preceding frames of imaging data that are recorded on the frame memory, and sequentially respectively outputs them in parallel, as video image data items, for each frame, to respective camera signal processing units. In the camera signal processing units, a video output, a viewfinder output, codec units, and recording units, processing similar to that when a frame rate that is ¼ the imaging frame rate is executed.
