Abstract
In the present invention, first of all, an image in each field is monitored by carrying out monitoring. An evaluation value of an AE is calculated from a result of the monitoring, and if the result of the calculation shows that the image is not in low luminance, data in each of the fields is read out by carrying out an exposure, and a normal process for a still image is performed. If the result of the calculation shows that the image is in the low luminance, the exposure and read out of the field data such as a difference in a luminance in each of the fields are carried out, and first and second field data are compared. Then, whether an object moves or not is determined from a result of the comparison, and if the object is determined to be moved, the normal process for the still image is performed. If the object is determined not to be moved, the entire field data from the first to third field data are added.
