ABSTRACT:
A digital still camera includes a pickup lens, which focuses object light on a focal plane. An externally operable focus adjusting ring adjusts focusing of the pickup lens. A CCD image sensor is disposed on the focal plane, for receiving the object light to produce image data. A liquid crystal display (LCD) panel displays an image according to the image data. An EEPROM stores information of an area split pattern having 36 partial areas in which the LCD panel is split. A CPU displays a focus adjusting state of the 36 partial areas distinctly during adjustment of the focus adjusting ring. CPU compares a focus evaluation value fna with a preceding evaluation value fnb, and extracts at least one of the 36 partial areas where the focus adjusting state is in-focus according to a result of comparison.
