Abstract

An image pickup apparatus is disclosed which provides an appropriate inclination guide display in accordance with an aspect ratio of a picked-up image and the like. The image pickup apparatus includes an inclination detector which detects an inclination of the image pickup apparatus, a display device capable of superimposedly showing an inclination guide display corresponding to a detection output from the inclination detector, on a picked-up image, and an aspect ratio setter which sets the aspect ratio of a picked-up image. The apparatus includes a display controller which controls whether or not to show the inclination guide display on the display device on the basis of the aspect ratio set by the aspect ratio setter.

Claims

1. An image pickup apparatus comprising:

a display device which displays a picked-up image;

an inclination detector which detects an inclination of the image pickup apparatus;

a display processor for showing an inclination guide display corresponding to the inclination of the image pickup apparatus detected by the inclination detector; and

a display controller which controls display of the inclination guide display in accordance with a zoom position of the image pickup apparatus,

wherein the display controller switches whether or not to show the inclination guide display on the display device based on the inclination of the image pickup apparatus detected by the inclination detector, and

wherein the inclination at which the inclination guide display is switched between a display and a non-display is smaller when a zoom position of the image pickup apparatus is on a wide-angle side from a predetermined zoom position than that when the zoom position is on a telephoto side from the predetermined zoom position.

2. An image pickup apparatus comprising:

a display device which displays a picked-up image;

an inclination detector which detects an inclination of the image pickup apparatus;

a display processor for showing an inclination guide display corresponding to the inclination of the image pickup apparatus detected by the inclination detector; and

a display controller which controls display of the inclination guide display in accordance with a zoom position of the image pickup apparatus,

wherein the display controller controls so as to show the inclination guide display whose display angle for a same inclination detected by the inclination detector is larger when the zoom position of the image pickup apparatus is on a wide-angle side from a predetermined zoom position than that when the zoom position is on a telephoto side from the predetermined zoom position.

3. An image pickup apparatus comprising:

a display device which displays a picked-up image;

an inclination detector which detects an inclination of the image pickup apparatus;

a display controller which performs a control so as to show an inclination guide display corresponding to the inclination of the image pickup apparatus detected by the inclination detector, wherein the inclination guide display indicates a degree of the inclination of the image pickup apparatus from a regular position in a rotational direction; and

a detection sensitivity changer which changes detection sensitivity of the inclination detector in accordance with a zoom position of the image pickup apparatus,

wherein the display controller shows the inclination guide display as to indicate a degree more exaggerated than an actual degree of the inclination of the inclination of the image pickup apparatus when the detection sensitivity of the inclination detector is increased by the detection sensitivity changer.

4. The image pickup apparatus according to claim 3, wherein the detection sensitivity changer changes the detection sensitivity so that the detection sensitivity is increased when the zoom position detected by a zoom position detector is on a wide-angle side from a predetermined zoom position than that when the zoom position is on a telephoto side from the predetermined zoom position.

5. A control method of an image pickup apparatus, the method comprising steps of:

displaying a picked-up image;

detecting an inclination of an image pickup apparatus;

showing an inclination guide display corresponding to the inclination of the image pickup apparatus detected in the detecting step;

controlling display of the inclination guide display in accordance with a zoom position of the image pickup apparatus; and

switching whether or not to show the inclination guide display based on the inclination of the image pickup apparatus detected in the detecting step,

wherein the inclination at which the inclination guide display is switched between a display and a non-display is smaller when a zoom position of the image pickup apparatus is on a wide-angle side from a predetermined zoom position than that when the zoom position is on a telephoto side from the predetermined zoom position.

6. A control method of an image pickup apparatus, the method comprising steps of:

displaying a picked-up image;

detecting an inclination of an image pickup apparatus;

performing a control so as to show an inclination guide display corresponding to the inclination of the image pickup apparatus detected in the detecting step, wherein the inclination guide display indicates a degree of the inclination of the image pickup apparatus from a regular position in a rotational direction; and

changing detection sensitivity of the detecting step in accordance with a zoom position of the image pickup apparatus,

wherein the inclination guide display is switched as to indicate a degree more exaggerated than an actual degree of the inclination of the image pickup apparatus when the detection sensitivity of the detecting step is increased.
