A camera system includes two or more sensor arrays and an optical path. The sensor arrays are on the same sensor chip. Each sensor array includes the same field of view (FOV) as each other sensor array. The optical path includes a main lens and a metalens that are shared by each sensor array, and a microlens associated with each sensor array. The metalens splits incident light into different spectrums of light and directs each respective spectrum to a corresponding sensor array. The different spectrums of light include at least two of visible light, near infrared light, shortwave infrared and longwave infrared, and at least one sensor array includes single-photon avalanche diodes. The image processor that provides image processing, object recognition and object tracking and/or image fusion functionality may be on the same sensor chip as the sensor arrays.

[Object] To provide an image-capturing apparatus, an image-capturing method, and a program that are suitable to perform image-capturing with pieces of light of different wavelengths. [Solving Means] An image-capturing apparatus according to the present technology includes an imaging element, an optical element, a first stop, a second stop, and a stop controller. The imaging element performs wavelength separation on incident light to obtain first light of a first wavelength and second light of a second wavelength, and photoelectrically converts the first light and the second light, the first light and the second light being included in the incident light. The optical element collects light in the image-capturing apparatus. The first stop is provided in a path of the incident light, and includes a first opening portion and a first blocking portion, the first opening portion being a portion through which the first light and the second light are transmitted, the first blocking portion being a portion that blocks the first light and through which the second light is transmitted. The second stop is provided in the path of the incident light, and includes a second opening portion and a second blocking portion, the second opening portion being a portion through which the first light and the second light are transmitted, the second blocking portion being a portion that blocks the second light and through which the first light is transmitted. The stop controller separately controls a size of the first opening portion and a size of the second opening portion.

The present disclosure provides systems and methods for collecting multispectral images with a mobile device having a camera with an image sensor, such as a mobile phone. The systems and methods of the present disclosure control, support and power one or more light sources to emit single or multiple wavelengths of light onto an object. The system further supports and controls the camera within the mobile device to capture a series of images or video in the different or same light wavelengths and geometries. The resulting series of images may be used individually or collectively to detect and compare features in an object. This system may be used for the capture of multispectral images or video that could individually or collectively reveal features in the object that may not be visible in a single image.
