Image sensing device and its mfg. method, image sensing equipment with said device

Abstract

The present invention provides an image sensing device as well as manufacturing method, camera shooting device containing the imaging sensing device. The image sensing device is characterized in that including: prism unit, for the incidence of beam from articles and forming object image on an imaging plane, has at least two reflecting surfaces each having a free-form surface shape, and the incidence optical axis for the incidence of beam from object and the ejaculatory axis for emitting beam to the imaging plane from the prism unit are basically parellel with each other, and have prescribed distance; a camera shooting element, locating on the imaging plane and transforming the object image on the imaging plane to electric signal; an adjustment member for finely adjusting the prism unit at a position of the prism unit in a direction perpendicular to the light-receiving surface of the image sensing element.

Description

technical field [0001] The present invention relates to an imaging device used in a digital camera, a mobile phone with a camera, and the like, and more particularly to an imaging device using a prism using a free-form surface as a reflection surface, etc., an imaging device using the imaging device, and manufacturing of the imaging device method. Background technique [0002] [Patent Document 1] JP-A-2001-272587 [0003] [Patent Document 2] JP-A-2002-267928 [0004] [Patent Document 3] JP-A-2002-320122 [0005] [Patent Document 4] JP-A-11-326766 [0006] [Patent Document 5] JP-A-2002-196243 [0007] [Patent Document 6] JP-A-2003-84200 [0008] In recent years, many imaging devices using coaxial optical systems have been applied for as imaging devices used in digital cameras and camera-equipped mobile phones. A coaxial system refers to an optical system in which optical elements such as lenses are arranged rotationally symmetrically with respect to the optical axis of ...

Problems solved by technology

[0019] And, in the case of mass-producing such imaging devices, it is difficult to accurately image the subject image on the optical system or the holding frame member of the optical system due to dimensional or characteristic deviations, assembly deviations, and the like. The imaging surface of the imaging element that reads the image

[0020] In order to solve this problem, in each imaging element, it is necessary to perform focal plane adjustment (hereinafter referred to as fc adjustment) so as to optimize the relationship between the position of the incident surface of the imaging element and the imaging surface, but regarding the The fc adjustment mechanism is not described in the aforementioned Patent Documents 1 to 6

Also, there is no disclosure of a method of realizing the fc adjustment mechanism with a small number of components
