Abstract
When a chart is used as a subject, whether or not the chart can be captured for storage is determined based on the result obtained through distance measurement at a plurality of locations in a field captured for temporary display on a viewfinder. For example, a maximum difference of distances ΔL is calculated. It is determined that the chart cannot be captured for storage if ΔL is greater than a depth of field or is greater than a predetermined TL. A message indicating that the chart cannot be captured for storage is provided. Furthermore, it is determined that the subject is not the chart to be captured for storage if a subject size does not fall within a predetermined range.
