Embodiment 1

[0052] figure 1 It is a figure showing the external appearance shape of the mobile telephone device with a camera which concerns on Example 1 of this invention.

[0053] exist figure 1 Among them, 1 represents the whole of the mobile phone device with a camera of the present embodiment, 11 represents the housing of the mobile phone device, and 12 represents a light (video light) that continuously illuminates the object to be photographed using a light-emitting diode (LED) that emits light with high brightness. ). 13 is a camera that has an imaging element such as a CCD and an optical lens, and is capable of shooting moving pictures in addition to still pictures. 14 is a display (display means) such as a liquid crystal provided in a rectangular shape for displaying operation information, character information, and images captured by a camera. 15 is a group of input keys (buttons) for specifying and selecting telephone numbers, characters, and image data, and includes a light...

Embodiment 2

[0070] In the first embodiment, the light distribution lens 33 is arranged between the light emitting diode 32 and the transparent cover 34, but in order to arrange the light distribution lens 33 at a given position, it is necessary to use other members not shown.

[0071] In Example 2 described below, a case where the light distribution lens is arranged on the light emitting diode 32 so as not to require other components will be described.

[0072] image 3 It is a sectional view showing the structure of the lamp 12 according to the second embodiment of the present invention. Moreover, the overall structure of the mobile phone device 1 with a camera of the present embodiment 2 is the same as that of the first embodiment. figure 1 .

[0073] The difference between embodiment 1 and embodiment 2 is: in the light distribution lens 39 of this embodiment, at the bottom of the lens part 39a (the light distribution lens 32 side), there is a light distribution lens installed on the ...

Embodiment 3

[0076] In said embodiment 1 and embodiment 2, the light distribution lens 33 or the light distribution lens 39 is arranged between the light emitting diode 32 and the transparent cover 34, so the space, weight and thickness of the light distribution lens 33 or the light distribution lens 39 part , the space, weight and thickness of the transparent cover 34 part are necessary in the mobile phone device.

[0077] In Example 3 described below, regarding the shape of the transparent cover, a case where the light distribution lens is not required by forming a convex lens surface to have the light collecting function of the light distribution lens will be described.

[0078] Figure 4 It is a sectional view showing the structure of the lamp 12 according to Embodiment 3 of the present invention. Moreover, the overall structure of the mobile phone device 1 with a camera of the present embodiment 3 is the same as that of the embodiments 1 and 2. figure 1 .

[0079] The difference be...

Abstract

A mobile telephone device (1) having a camera (13) for imaging a moving picture of an object further includes illumination means (12) for illuminating the object by using a light emitting diode, switch means (21) for causing the illumination means (12) to emit light, a light orientation lens for converging the light emitted from the illumination means (12) toward the object, and a transparent cover for protecting the light orientation lens. These components are arranged on the front side as the object side of the illumination means (12), so that the requirements for small size, light weight, and thin thickness are satisfied while adding a light capable of continuously emitting light.

Description

technical field [0001] The present invention relates to a mobile phone device having a camera for capturing moving images with a solid-state image pickup device, and more particularly to a mobile phone device with a camera provided with an illumination unit for use when illumination is insufficient, such as at night. Background technique [0002] In recent years, mobile phone devices with still picture cameras have been commercialized, but the size of the imaging element or lens is limited. Since the size of the mobile phone device cannot be large, it is difficult to capture the subject in a dark place. Therefore, it is known that a flash used in a general camera is built into a mobile phone with a still camera, or an external flash is connected to a mobile phone with a still camera, so that pictures can be taken even in dark places. thing. [0003] For example, Japanese Unexamined Patent Publication No. 2001-320622 shows a conventional example in which a flash unit is buil...
