Embodiment Construction

[0021] Figure 1 illustrates a general digital imaging device that may be used in some embodiments of the present invention. Note that embodiments of the present invention may also be used in digital cameras other than the arrangement of Figure 1, which is only one example of a possible configuration.

[0022] The device of FIG. 1 includes an image sensing device 100 . The image sensing device includes a lens assembly and an image sensor. The structure of the device 100 will be described in more detail below. Image sensing devices capture images and convert the captured images into electronic form. The electrical signal generated by apparatus 100 is directed to A / D converter 102, which converts the analog signal into digital form. The digitized signal goes from the converter to the signal processor 104 . Image data is processed in a signal processor to create an image file. The output signal of the image sensing device 100 contains raw image data that needs post-processing...

Abstract

An imaging device comprising at least three image capturing apparatuses is provided. Each apparatus includes a lens system and a sensor and is configured to produce an image. The device further comprises a processor configured to combine at least a portion of the images with each other to produce a colour image. Each lens system comprises a phase mask which modifies the phase of incoming rays of light such that distribution of rays after the lens system is insensitive to the location of the sensor.

Description

technical field [0001] The invention relates to the creation of color images in an imaging device comprising at least three image capture devices. Background technique [0002] The popularity of photography is constantly increasing. Especially digital photography, as the supply of cheap digital cameras has improved. Integrated cameras in mobile phones have also contributed to the increased popularity of photography. [0003] The demand for compact cameras is constantly increasing. The small size of the camera is a challenge for camera manufacturers because reducing the size of the camera is best done without reducing the quality of the images the camera produces. [0004] One possibility to reduce the size of the camera is to use the lenslet technique. This solution is especially useful in digital cameras. In lenslet technology, a camera is implemented with at least three image capture devices, each device comprising an independent lens system. The device uses sensors ...
