Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a camera-equipped mobile terminal, and more particularly to a camera-equipped mobile terminal that can shoot even when the illuminance around a subject is low.
[0002]
[Prior art]
Conventional camera-equipped mobile phones and camera-equipped information terminals can be attached to and detached from the camera body as an illumination source for the subject in the event of insufficient illuminance when shooting the subject (at low illuminance). Some were equipped with an external flashlight configured. In recent years, these apparatuses have a built-in white LED (Light Emitting Diode) or a three-color (red-blue-green; hereinafter, referred to as RBG) LED provided exclusively for the white LED or three-color LED. In some cases, an (RBG) LED emits light at the time of shooting to be used as an illumination source for camera shooting at low illuminance.
[0003]
Further, in such an apparatus, it is proposed in Patent Documents 1 and 2 to use backlight light of a liquid crystal display as an illumination source for photographing at the time of photographing with a camera. FIG. 13 is a diagram illustrating an imaging device disclosed in Patent Document 1. FIG. 14 is a side view of a digital camera with a liquid crystal monitor disclosed in Patent Document 2 in a state of performing macro shooting.
[0004]
First, referring to FIG. 13, in an imaging apparatus, an imaging unit 101 includes a photographic lens 102 for capturing an image of a subject, and has a built-in image sensor such as a CCD at a focal position of the photographic lens 102. Further, a display unit 104 is attached to the imaging unit 101 via a connecting member 103. The display unit 104 includes a liquid crystal display 105, and can rotate 360 degrees in the vertical direction about the connecting member 103 as a rotation axis as indicated by an arrow A. The display unit 104 is used as a viewfinder during normal shooting.
[0005]
In the configuration shown in FIG. 13, when the illuminance of the subject 106 is insufficient, the display unit 104 is rotated to irradiate the backlight 106 of the liquid crystal display 105 toward the subject 106, thereby obtaining a liquid crystal display. The subject 106 can be photographed by the imaging unit 101 using the backlight 107 of the container 105 as an illumination source.
[0006]
Next, a digital camera with a liquid crystal monitor shown in FIG. 14 will be described. In the digital camera 201 with a liquid crystal monitor, when the user selects the macro shooting mode at the time of macro shooting, transmission of image signals from a CCD (charge-coupled device) is stopped on the liquid crystal screen 203a of the liquid crystal monitor 203, and the liquid crystal is stopped. Image data is transmitted so that the screen 203a is entirely a white screen. As a result, the liquid crystal screen 203a serves as an illumination source that displays white on the entire surface and emits white light.
[0007]
By rotating a liquid crystal monitor 203 connected to the main body 202 by a connecting member 210 via a rotating shaft 211 and a rotating shaft 212, the direction of white light emitted from the liquid crystal screen 203a is changed by the shooting lens 204. The direction can be set so as to irradiate the imaging region. This makes it possible to uniformly illuminate the shooting area of the subject 250 with a predetermined illuminance.

Next, the CPU 40 records the image display data from the imaging device 14 in the memory 41 in response to the depression of the shutter button in S36.
[0064]
Next, in S37, the CPU 40 causes the camera-captured image captured in S36 to be temporarily displayed on the main liquid crystal display device 11, and proceeds to S38. After the image captured by the camera is temporarily displayed, the camera image is displayed on the main liquid crystal display device 11, as in S31.
[0065]
Next, in S38, the CPU 40 determines whether or not the camera shooting mode has been ended. If it is determined that the camera shooting mode has not been ended, the process returns to S34, and the above control is repeated. On the other hand, when it is determined that the camera shooting mode has been ended, the power supply to the imaging device 14 is turned off to end the camera shooting mode.
[0066]
