Image observation apparatus

An image observation apparatus comprising:

• a main body which has an image display device;
• a first detector which is provided in the main body and which detects that a user observes an image being displayed on the image display device;
• a second detector which detects a posture of the main body;
• and
• a controller which controls the image being displayed on the image display device in response to a signal which is output from the second detector,
• wherein the controller does not allow changing the image being displayed on the image display device in response to the signal which is output from the second detector when the first detector detects that the user does not observe the image being displayed on the image display device.

An image observation apparatus comprising:

• a main body which has an image display device;
• a controller for controlling the image observation apparatus;
• and
• a first detector for detecting whether a user stops observing an image which is displayed on the image display device or not,
• wherein the controller sets at least one setting condition of the image observation apparatus to a predetermined condition such that the image which is displayed on the image display device is not allowed to change when the first detector detects that the user stops observing the image.

An image observation apparatus comprising:

• a main body which has an image display device, the main body being configured to be held in a user's hands when the user observes an image being displayed on the image display device;
• an operational member which is provided on the main body and which is operated manually in order to give an instruction to the image observation apparatus;
• a detector for detecting a posture of the main body;
• and
• a controller for controlling the image which is displayed on the image display device in response to a signal which is output from the detector,
• wherein the controller does not allow changing the image which is displayed on the image display device in response to the signal which is output from the detector when the operational member is operated.

An image observation apparatus comprising:

• a main body which has an image display device;
• an operational member which is provided on the main body and which is operated manually in order to give an instruction to the image observation apparatus to prevent circuitry which provides the image display device with context from changing the displayed image;
• a detector for detecting a posture of the main body;
• and
• a controller for controlling the image which is displayed on the image display device in response to a signal which is output from the detector,
• wherein the controller does not allow changing the image which is displayed on the image display device in response to the signal which is output from the detector when the operational member is operated.
