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 combination unit combines the restored long exposure data and the short exposure data.
