Phone camera with flash and indication light sharing common output
View Patent ↗A portable electronic device with a camera of the present invention comprises a camera portion, a first light source outputting a first light as a strobe light emitting operation in connection with a photographing operation of the camera portion, a second light source outputting a second light for display and an illumination lens through which the first light and the second light exit the device. The illumination lens outputs both of the first light and the second light. A light diffuser, such as a prism reflects the second light to the illumination lens side between the illumination lens and the first light source, the second light reaching the first light source having been made as small as negligible.
1. A mobile telephone with a camera, comprising:
a camera portion;
a first light source for outputting white light as a strobe light emitting operation in connection with a photographing operation of said camera portion;
a second light source for outputting non-white light for display of incoming indication; and
a lens for outputting said white light and said non-white light to the outside therethrough, wherein said lens is provided with a first entrance face through which said white light comes in, a second entrance face through which said non-white light comes in and a common exit face opposite to said first entrance face to output said white light and said non-white light therethrough while said first entrance face and said second entrance face are on different planes crossing to each other,
wherein a light diffusing sheet is provided in contact with or adjacently to either of said first entrance face and said second entrance face of said lens,
wherein said white light outputted from said first light source is inputted into said first entrance face of said lens through said light diffusing sheet and is outputted from said common exit face of said lens to the outside, and
wherein said non-white light outputted from said second light source is inputted into said second entrance face of said lens, is reflected and diffused by said light diffusing sheet and is outputted from said common exit face of said lens to the outside.
2. A mobile telephone with a camera according to claim 1 , wherein said second light source is used for illumination display during conversation.
3. A mobile telephone with a camera according to claim 1 , wherein said light diffusing sheet is a sheet selected from a group consisting of a prism sheet and a diffusing sheet.
4. A mobile telephone with a camera according to claim 1 , wherein said first light source and said second light source each are provided with a light emitting diode.
5. A mobile telephone with a camera according to claim 1 , wherein said first light source is provided with a white light emitting diode.
6. A mobile telephone with a camera according to claim 1 , wherein said second light source is provided with a blue light emitting diode.
