Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup device suitably applied to a mobile information terminal such as a mobile phone.

[0002]

2. Description of the Related Art A conventional image pickup device will be described by taking a mobile phone as an example. In the conventional mobile phone with a solid-state imaging device, the solid-state imaging device of the solid-state imaging device is mounted on a circuit board (mobile phone main body substrate) of the mobile phone main body, and the lens barrel of the solid-state imaging device is the mobile phone main body substrate. It is fixed by screwing or gluing. A cover glass is attached to the mobile phone casing, and a window for transmitting incident light is formed in the cover glass. Further, an imaging lens and an optical filter for forming an image of the incident light on the solid-state imaging device are supported and fixed to the lens barrel.

In such a conventional mobile phone with a solid-state image pickup device, the positioning accuracy of the lens barrel of the solid-state image pickup device in the direction perpendicular to the optical axis is as follows: Mounting accuracy of the image pickup device (b) Positioning accuracy of the lens barrel with respect to the solid-state image pickup device (c) Positional accuracy of the pattern and outer shape on the mobile phone body substrate (d) Positioning accuracy between the mobile phone body substrate and the mobile phone housing Decided.

Since the positional accuracy of the lens barrel and the mobile phone housing is poor, it is necessary to enlarge the window provided in the mobile phone housing for the image pickup device. When the window becomes large, extra light enters the image pickup device, image performance is deteriorated, and designability is deteriorated due to the positional deviation between the window and the lens barrel.

Further, the accuracy of the gap between the lens barrel of the solid-state image pickup device and the housing of the portable telephone (positioning accuracy in the direction parallel to the optical axis).
Is determined by (e) the mounting accuracy of the lens barrel to the mobile phone body substrate, and (f) the positioning accuracy of the mobile phone body substrate and the mobile phone housing.

[0006]

In the conventional portable telephone with the solid-state image pickup device, the positioning accuracy of the lens barrel of the solid-state image pickup device and the casing of the portable telephone is determined by the factors (a) to (f). Neither the positioning accuracy in the direction perpendicular to the optical axis nor the gap (positioning accuracy in the direction parallel to the optical axis) can be obtained with high accuracy.

Since the positional accuracy of the lens barrel and the mobile phone housing in the direction perpendicular to the optical axis is poor, the imaging lens supported and fixed to the lens barrel and the window of the cover glass attached to the mobile phone housing. The position accuracy in the above direction is also poor, and for this reason, it is necessary to enlarge the window of the cover glass. By enlarging the window of the cover glass, extra light is incident on the solid-state imaging device, image performance is deteriorated, and the design property is deteriorated due to the positional shift between the window and the housing.

Further, since the accuracy of the gap between the lens barrel and the mobile phone housing is poor, it is necessary to increase the gap between the solid-state image pickup device and the mobile phone housing, which increases the thickness of the mobile phone which is becoming thinner. There is a problem.

As described above, in the conventional solid-state image pickup device and the mobile phone with the solid-state image pickup device, the lens barrel of the solid-state image pickup device cannot be accurately positioned in the case of the mobile phone (the image pickup lens is in the window of the cover glass). There is a problem that the image performance and the design are deteriorated and the mobile phone cannot be made thin.

The present invention has been made to solve such a conventional problem, and improves the positional accuracy between the lens barrel of the solid-state image pickup device and the mobile phone housing, and the solid-state image pickup device is installed in the mobile phone housing. The purpose of the present invention is to improve the image performance and the design and to make the mobile phone thinner by accurately mounting it in a small space.
