IMAGING MODULE AND IMAGING DEVICE

摘要

The present invention relates to an imaging device including a multi-lens including a central optical system (wide-angle lens) and an annular optical system (telescopic lens) which have a common optical axis, an image sensor, and an array lens provided on the incidence surface side of the image sensor and including microlenses (pupil imaging lens). In a preferred aspect of the present invention, two images having different characteristics are generated based on a pupil image of each unit block including 3×3 light reception cells assigned to each of the microlenses of the array lens. The unit block has eight surrounding light reception cells that correspond to one of the two images, and the eight surrounding light reception cells in the unit block are configured to output RGB pixel signals in all wavelength regions necessary for generating this one image.

主权项

1. An imaging module that simultaneously captures X subject images having different characteristics, and outputs pixel signals in a plurality of wavelength regions for at least one of the X subject images, where X is an integer equal to or greater than 2, the imaging module comprising:
a multi-lens that has X areas on which subject light is incident, and causes the subject images having different characteristics to be formed to overlap in the same image plane in each of the X areas; a pupil division device configured to divide a pupil image of the multi-lens into the respective X areas; and Y photoelectric converters arranged corresponding to X light reception areas that respectively receive X pupil images divided by the pupil division device, where Y is an integer equal to or greater than X+1, wherein: a plurality of photoelectric converters are arranged in at least one of the X light reception areas, the plurality of photoelectric converters arranged in the light reception area output the pixel signals in the plurality of wavelength regions, the pupil division device is an array lens including two-dimensionally arranged microlenses, the array lens being arranged on the incidence surface side of the photoelectric converters and causing the pupil image of the multi-lens to be incident on the Y photoelectric converters by the respective microlenses, and the array lens causes pupil images adjacent to each other among the pupil images respectively incident on the photoelectric converters due to the respective microlenses to partially overlap on the photoelectric converters.
