Title: COLOR IMAGING DEVICE, AND METHOD FOR OBTAINING COLOR IMAGES
Abstract:
Embodiments of the present invention provide a color imaging device, and a method for obtaining color images, for use in solving the problem that color filters are difficult to process. The color imaging device comprises a main lens, a microlens array, and an imaging sensor that are sequentially arranged along an optical transmission path; the device further comprises a first color filter disposed at an aperture stop of the main lens; the main lens, the first color filter, the microlens array, and the imaging sensor are parallel to each other and co-axial; the imaging sensor is located at the focal point of the microlens array; light, when reaching the imaging sensor from a microlens, covers a M*N pixel array of the imaging sensor; the first color filter comprises at least one filter capable of performing filtering to obtain at least one color; the size of the first color filter in any direction vertical to an axis is not less than the size of the main lens in the corresponding direction.
