Problems solved by technology

However, regarding thinning, the focal length of the lens is required to some extent in accordance with the number of pixels, so the distance between the lens part and the imaging element cannot be reduced, and there is a limit to thinning
[0006] In addition, in order to obtain color image data, each pixel receives light of three wavelengths, but since the refractive index of the lens is different for each wavelength of light, chromatic aberration occurs
In order to correct chromatic aberration, it is necessary to stack multiple lenses, the camera module becomes expensive, and it also hinders thinning

Embodiment Construction

[0024] Embodiments of the present invention will be described in detail with reference to the drawings. figure 1 An exploded view showing the camera module of this embodiment. As shown in the figure, the camera module according to this embodiment includes a rectangular plate-shaped imaging element 1, a plate-shaped lens member 2 facing the imaging element 1, and a plate-shaped lens member 2 disposed between the imaging element 1 and the lens member 2. The partition plate 3 receives the light condensed by the lens member 2 by the imaging element 1, converts the light into an electrical signal by the imaging element 1, and obtains image data.

[0025] In the imaging element 1, a plurality of photoelectric conversion elements are arranged on a light receiving surface. In addition, since the photoelectric conversion elements are extremely small, they are not shown in the drawings. Each photoelectric conversion element has a color filter that passes only one of red, green, and b...

Abstract

This invention provides a camera module which may reduce the focal length of a small lens without changing pixel number and does not generate the colour difference. A shooting component comprises at least three regions. A first region (10) of the shooting component (1) comprises a filer in which only the red light can be passed. A second region (11) of the shooting component (1) comprises a filer in which only the green light can be passed. A third region (12) of the shooting component (1) comprises a filer in which only the blue light can be passed. A lens component (2) comprises multiple lens part (21) corresponding to each region of the shooting component (1), respectively.

Description

technical field [0001] The present invention relates to a camera module that receives light collected by a lens member by an imaging element to obtain image data, and particularly relates to a camera module that divides the imaging element into a plurality of areas and acquires data of each monochrome color in each area. Background technique [0002] Conventionally, there is known a camera module that receives light collected by a lens member having a lens portion with an imaging element such as a CCD or CMOS, converts the light into an electrical signal, and obtains image data. An imaging element used in such a camera module divides a light-receiving surface into a plurality of pixels, and performs photoelectric conversion in each pixel. Image data is obtained in color, and a color filter of any color among the three primary colors of light is installed in one pixel, and an R signal is detected in a pixel of a color filter set to pass only red light, and a color filter set ...
