Image playback device and method and electronic camera with image playback function

An electronic camera comprising:

• an imaging means which produces moving-picture image information by imaging an object via an imaging optical system;
• an environmental parameter detection means which detects at least one environmental parameter indicative of a surrounding environment at the time of imaging;
• a medium recording means which receives moving-picture image information produced by the imaging means and at least one environmental parameter detected by the environmental parameter detection means, and records such moving-picture image information and the at least one environmental parameter on a recording medium as recorded information;
• a medium playback means which reads out the recorded information from the recording medium;
• a time period discriminating means which receives the at least one environmental parameter from the recorded information read out by the medium playback means, and discriminates time periods during which the received at least one environmental parameter agrees with at least one pre-set condition;
• and
• a playback display means which plays back and displays moving-picture image information contained in the recorded information in accordance with results of the discrimination performed by the time period discriminating means.

An image playback method comprising:

• reading out recorded information that has been recorded on a recording medium;
• discriminating time periods during which the read out recorded information agrees with at least one pre-set condition;
• and
• playing back and displaying moving-picture image information contained in the recorded information in accordance with the results of the discriminating.

An electronic camera operating method comprising:

• producing moving-picture image information by imaging an object via an imaging optical system;
• detecting at least one environmental parameter indicative of a surrounding environment at the time of imaging;
• receiving produced moving-picture image information and at least one detected environmental parameter, and recording such moving-picture image information and at least one environmental parameter on a recording medium as recorded information;
• reading out the recorded information from the recording medium;
• receiving the at least one environmental parameter from the recorded information read out, and discriminating time periods during which the received at least one environmental parameter agrees with at least one pre-set condition;
• and
• playing back and displaying moving-picture image information contained in the recorded information in accordance with results of the time period discriminating.
