Abstract

A camera informs a user of a posture of a camera or availability of the detection and includes an image processing apparatus having a photographing part for taking an image, a posture detecting part for detecting the posture of the photographing part in taking the image, and a display part for displaying information for allowing the user to distinguish the posture detected by the posture detecting part together with the image to be taken by the photographing part.

Claims

1. An image processing apparatus for informing a user of the posture thereof comprising:

an image pickup element;

a posture detecting device configured to detect posture information of the image pickup element;

an operation member;

a control circuit configured to execute an image taking process for storing the image data obtained from an output of the image pickup element and the posture information detected by the posture detecting device on a recording medium, in accordance with an operation of the operation member; and

a display device configured to display an image representing a visual facsimile of said image processing apparatus whose posture reflects the posture of said image processing apparatus, the visual facsimile including visually distinguishable representations of the top and bottom of said image processing apparatus the posture of said image processing apparatus and to rotate the image representing the posture of said image processing apparatus based on the image data stored in the recording medium, using the posture information stored in the recording medium, and display the thus rotated image,

wherein the posture information indicates angles which are set stepwise and the image to be displayed by said display device is allowed to be rotated based on any of the angles, and

wherein said display device is configured to continuously display an image based on the output of the image pickup element and the image representing the posture of said image processing apparatus based on the posture information detected by said posture detecting device, before the execution of the image taking process, in accordance with an operation of said operation member.

2. An image processing apparatus according to claim 1,

wherein the posture detecting device is configured to detect a change of the posture of the image pickup element, and

wherein the display device continuously displays an image based on the output of the image pickup element and the posture information after detection of the change of the posture.

3. An image processing apparatus according to claim 1,

wherein the display device displays information designating the vertical direction, as the posture information.

4. An image processing apparatus according to claim 1, wherein the display device displays information in accordance with a posture of the image processing apparatus, as the posture information.

5. An image processing apparatus according to claim 1,

further comprising a setting member configured to switch over the image processing apparatus between an image taking mode in which the image data obtained from the output of the image pickup element is stored on the recording medium and an image reproducing mode in which an image is reproduced on the display device based on the image data obtained in the image taking mode, and

wherein in the image taking mode, the display device continuously displays an image by using the output of the image pickup element and the posture information detected by the posture detecting device.

6. An image processing apparatus according to claim 5, wherein in the image reproducing mode, said display device is configured to rotate an image produced based on the image data stored in the recording medium, using the posture information stored in the recording medium.

7. An image processing apparatus according to claim 1, wherein said display device is configured to rotate, in units of 90-degrees, the image produced based on the image data stored in the recording medium, using the posture information stored in the recording medium, and to display the thus rotated image.

8. An image processing method for informing a user of the posture of an image processing apparatus comprising:

a posture detecting step for detecting posture information of an image pickup element of the image processing apparatus;

a display step for displaying an image representing a visual facsimile of said image processing apparatus whose posture reflects the posture of said image processing apparatus, the visual facsimile including visually distinguishable representations of the top and bottom of said image processing apparatus and for rotating the image representing the posture of the image processing apparatus based on the image data stored in a recording medium, using the posture information detected by said posture detecting step, and displaying the thus rotated image; and

an image taking step for storing image data obtained from the output of the image pickup element and the posture information detected by said posture detecting step, on a recording medium, in accordance with an operation of an operation member,

wherein the posture information indicates angles which are set stepwise and wherein said displaying step rotates the image based on any of the angles, and

wherein said displaying step continuously displays an image based on the output of the image pickup element and the image representing the posture of the image processing apparatus based on the posture information detected by said posture detecting step, before the execution of the image taking step, in accordance with an operation of the operation member.

9. An image processing method according to claim 8,

wherein when a change of the posture of the image pickup element is detected at the posture detecting step, an image based on the output of the image pickup element and the posture information after detection of the change of the posture are displayed at the display step.

10. An image processing method according to claim 8, wherein information designating the vertical direction is displayed as the posture information at the display step.

11. An image processing method according to claim 8, wherein information in accordance with the posture of an apparatus executing the image processing method is displayed as the posture information at the display step.

12. An image processing method according to claim 8,

further comprising a setting step for switching over between an image taking mode in which the image data obtained from the output of the image pickup element is stored on the recording medium and an image reproducing mode in which an image is reproduced on a display device based on the image data obtained in the image taking mode, and

wherein in the image taking mode, the display device continuously displays an image by using the output of the image pickup element and the posture information detected by the posture detection step.
