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.

Abstract: A wheel bearing apparatus has an outer member, an inner member, and double row rolling elements are contained between the outer raceway surfaces. Seals are mounted in openings formed between the outer member and the inner member. A shoulder height H of the inner raceway surface of the inner ring is set with a range of 0.4-0.8 times a diameter “d” of the ball (H/d=0.4-0.8). 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 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).
