AI Technical Summary

Benefits of technology

The solution effectively prevents image pickup failures by reliably alerting users to the macro mode setting, allowing them to change modes if necessary, thereby improving operational accuracy and user experience.

Problems solved by technology

However, if a user inadvertently photographs an object located at a far distance or middle distance by using the macro photographing mode, this results in failure in the image pickup because an image of the object is out of focus.
If an image is photograph panoramically with a photo film having a high photo film sensitivity, image quality will be low because of enlargement in the size.
In the field of the digital still camera, however, known cameras do not have a structure of apparently clarified alarm or notice of an icon of the macro photographing mode at the same time as or shortly before the image pickup.
A user is likely to miss or neglect the icon or indicia on the display panel for indicating the macro photographing mode.
A problem arises in high probability in his or her error in the image pickup because of missing the setting of the macro photographing mode.

Embodiment Construction

[0047]In FIG. 1, a digital still camera 10 includes a camera body 11 and a lens barrel 12. The lens barrel 12 protrudes from a front of the camera body 11, and has a pickup lens incorporated therein. An upper face of the camera body 11 has a power switch 13 and a shutter release button or recording trigger switch 14. The shutter release button 14 has a construction depressible at two steps. At first, the shutter release button 14 is depressed to turn on for halfway depression or at a first step. This causes the digital still camera 10 to adjust the focusing of the taking lens, adjust the exposure and other items for image pickup. Also, the shutter release button 14 is more deeply depressed to turn on at the second step, in the form of full depression. Then a live image of an object being photographed is retrieved according to a pickup signal generated by a CCD image sensor. The image data of the image as a still image is written to a memory card.

Abstract

A digital camera has a shutter release button. A mode selector sets a selected one of a regular photographing mode and a macro photographing mode adapted to image pickup at a nearer distance of close-up than the regular photographing mode. An LCD display panel as a user interface has an alarm generating region which outputs an alarm signal visually as an enlarged alarm icon, and / or a sound source as a user interface audibly outputs sound of alarm message voice. A controller is responsive to depression of the shutter release button, for mode discernment by checking a state of the mode selector. The LCD and / or sound source is driven if the macro photographing mode is set selectively.

Description

[0001]This application is a Divisional Application of co-pending application Ser. No. 11 / 078,579, filed on Mar. 14, 2005, and for which priority is claimed under 35 U.S.C. § 120; and this application claims priority of Application Nos. 2004-072332 and 2004-072333 filed in Japan on Mar. 15, 2004 under 35 U.S.C. § 119; the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a digital camera with a mode selectable structure. More particularly, the present invention relates to a digital camera with a mode selectable structure, in which a macro photographing mode is selectable, and which is capable of reliably generating an alarm signal of a present setting of the macro photographing mode.[0004]2. Description Related to the Prior Art[0005]A digital still camera includes a CCD image sensor and an image pickup optical system, and is loaded with a storage medium or memory. The CCD phot...
