  • Patent number: 10158809
    Abstract: To prevent an increase in memory capacities in a device for performing image combination. A data generation unit executes long exposure processing and short exposure processing in sequence, the long exposure processing being performed to generate data including a plurality of pixel data items as long exposure data by performing exposure over a longer time period of two different exposure time periods, the short exposure processing being performed to generate data including a plurality of pixel data items as short exposure data by performing exposure over a shorter time period of the two different exposure time periods after the long exposure processing. A compression unit compresses the long exposure data to generate compression data. A memory holds the compression data over delay time corresponding to the shorter time period of the two exposure time periods. A decompression unit decompresses the held compression data to restore the long exposure data.

A shoulder height ? of a smaller diameter portion formed on the outermost circumference of the inner ring is set to a value ?/d?0.35. A corner, formed by the tapered surface and the inner raceway surface, is rounded to have a circular arc cross-section. A shoulder height H1 of the inner raceway surface from its bottom to the corner is set within a range of 0.40-0.50 times a diameter of the ball (d) (H1/d=0.40-0.50).
