Abstract

PROBLEM TO BE SOLVED: To solve the problem that a portable telephone which can be connected to a digital camera or is integrated with the digital camera can not be used as a magnifying glass since the portable telephone can merely photograph a subject as a general camera and does not have close-up and enlargement functions specially for photographic modes. SOLUTION: The portable telephone which can be connected to the digital camera or is integrated with the digital camera is provided with a close-up dedicated function for a photographic mode; and then an image pickup lens can be put in focus at a close-up position and an arbitrary enlarged image can be confirmed as a through image on a liquid crystal display part. Further, the telephone set is provided with a lighting means for lighting up the subject.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone to which a digital camera can be connected or a digital camera is integrated.

[0002]

2. Description of the Related Art Conventionally, a digital camera has been added to a portable telephone to which a digital camera can be connected or a digital camera is integrated, in order to photograph a subject and a person or a character scenery.

[0003]

A mobile phone that can be connected to a digital camera or an integrated digital camera can only shoot a subject as a general camera. There was no function.

[0004]

A portable telephone to which the digital camera of the present invention can be connected or which has an integrated digital camera is provided with a close-up function only in a photographing mode so that an image pickup lens is focused at a close-up position. In addition to the configuration, an arbitrary enlarged image can be confirmed as a through image on the liquid crystal display unit. In addition, when the lens camera is brought close to the subject, external light is blocked by the mobile phone itself, so that the illuminance is reduced. As a countermeasure, an illuminating means for irradiating a subject around the lens is provided.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A mobile phone to which a digital camera can be connected or an integrated digital camera, and a close-up lens provided with a close-up lens allows a magnified image to be confirmed as a through image on a liquid crystal display unit while the close-up is being performed. At the same time as having a mode, it is provided with means for illuminating the subject.

[0006]

FIG. 1 is a front view of a digital camera integrated type showing an embodiment of the present invention as viewed from a lens side. FIG. 2 is a rear view. In each drawing, the same numbers indicate the same components.

In FIG. 1, reference numeral 1 denotes a photographing lens. 2
Denotes a half mirror which is a positioning mirror.

In a normal photographing mode, the half mirror 2 functions as a mirror from the front side of the photographing lens 1 so that the range reflected on the half mirror 2 is used as a guide of the photographing range. Or On the other hand, in the close-up mode, light from the backlight of the liquid crystal display unit is transmitted to illuminate the subject in front of the taking lens 1.

Reference numeral 3 denotes a liquid crystal display unit. In addition to the status display function of the mobile phone, the display of contents and text mail, the subject captured by the photographing lens 1 is displayed as a through image. Alternatively, a scale, a cross cursor, and an integrated distance, which will be described later, are displayed together with the through image.

Reference numeral 4 denotes a mode selection button, which also functions as a shutter button in a photographing mode. 5 is an enlarge button,
6 is a reduction button.

7 is a decision button, 8 is an accumulation button,
Reference numeral 9 denotes a gap holding projection for keeping the distance between the subject and the photographing lens 1 constant, and reference numeral 10 denotes an antenna projection which forms a projection substantially in the same plane as the three gap holding projections 9.

Reference numeral 11 denotes a scale to be displayed on the liquid crystal display unit 3 with a through image. The scale 11 forms a scale indicating an actual size in conjunction with the zoom magnification.

Reference numeral 12 denotes a cross cursor which is displayed almost at the center of the liquid crystal screen 3 in combination with a through image. Reference numeral 13 denotes an integrated distance displayed on the liquid crystal screen 3 by being combined with a through image.

Next, these functions will be described. First, with the mobile phone turned on, the photographing lens 1 faces the subject to be photographed, such as a newspaper or a map, and the mode selection button 4 is pressed to select a close-up mode. Then, the photographing lens 1 is switched to the close-up lens position, and the focus is on a nearby newspaper or map.

At this time, the distance between the photographing lens 1 of the cellular phone and the newspaper or map as the subject is a fixed distance for close-up photography due to the protrusion of the three gap holding protrusions and the antenna protrusion 10 around the photographing lens 1. Is kept.

The illumination light of the backlight of the liquid crystal display unit 3 illuminates the liquid crystal display unit 3 and passes through the half mirror 2 to illuminate the subject.

Therefore, by bringing the taking lens 1 closer to the close-up position, even if the subject becomes dark, part of the illumination of the backlight of the liquid crystal display unit 3 illuminates the subject through the half mirror 2, so that the subject is clearly displayed on the liquid crystal display. It becomes possible to catch the part 3.

In particular, when it is desired to check characters and minute objects at night or in the dark, by using a mobile phone in this mode, the subject can be illuminated and checked.

Next, if you want to enlarge the display,
By pressing, the image is zoomed and displayed on the liquid crystal display unit 3.
When the user wants to reduce the size, the user presses the reduction button 6 to reduce the size.

In the close-up mode, the scale 11 can be synthesized and displayed on the liquid crystal display unit 3. The scale of the scale 11 is changed according to the zoom magnification ratio. By comparing the actual size of the subject on the enlarged screen with this cursor, the approximate size can be determined.

When a map mode below the close-up mode is selected, a cross cursor 12 can be displayed at the center. First, the scale of the map is input in advance. Next, when the mobile phone is relatively moved while pressing the accumulation button 8, the moving distance can be accumulated by digitally processing the image captured by the digital camera in the same principle as the optical mouse.

The moving distance according to the input magnification is displayed at the bottom of the display screen as an integrated distance.

[0023]

As described above, by adding a function of performing close-up illumination on a camera and enlarging and displaying the same, a mobile phone with a digital camera can be used as a digital magnifying glass.

For enlargement of a through image on the liquid crystal display unit of the imaging,
The image captured by the CCD or CMOS may be digitally zoomed, or may be an optical zoom in which the lens enlarges itself.

In the embodiment, the backlight of the liquid crystal display unit is used for illuminating the subject at the time of close-up photography. However, a light source dedicated to illumination may be provided.

At least a part of the case is a skeleton, so that even when the mobile phone is brought close to the subject, external light is transmitted to make shadows difficult, and illumination light of the liquid crystal display unit passes through the skeleton body through the subject. May be configured to be the illumination.

In the embodiment, these light sources are automatically illuminated in the close-up mode, but they may be manually turned on and off.
