摘要:
A method for obtaining a combined depth map, and a depth camera. The method is applicable to a processor in the depth camera. The depth camera includes the processor, at least one light emitting element, and at least two time-of-flight (ToF) sensors, and the composite irradiation range of the at least one light emitting element convers the composite field of view of the at least two ToF sensors. The light emitting elements in the depth camera modulate light signals with the same modulation signal and then transmit the modulated light signals; the ToF sensors demodulate, by using same demodulation signal corresponding to the modulation signal, the received modulated light signal reflected back by an object, so as to generate depth data; and the processor performs data fusion processing on all the received depth data, so as to obtain a combined depth map. By applying the technical solutions provided in the embodiments of the present application, the application requirements of the depth map of the large field of view can be satisfied, and the problem of mutual interference due to asynchronization of modulation and demodulation can be avoided.

A camera array comprises a plurality of cameras configured to capture images of a scene and an image processor configured to process at least a subset of images captured by the plurality of camera. The plurality of cameras comprises at least two cameras having different imaging characteristics including different fields of view comprising a wide field of view camera and a telephoto camera. The cameras having different imaging characteristics are configured to operate with at least one difference in operating parameters. The image processor is configured to: measure parallax within the processed images by detecting parallax-induced changes taking into account the position of the cameras that captured the images and by ignoring pixels in the images captured by the plurality of cameras that are in an exposed occlusion set; generate a depth map using the measured parallax; synthesize images having different levels of zoom; and synthesize an image at a zoom level between a zoom level of the wide field of view camera and a zoom level of the telephoto camera using the images captured by plurality of cameras and the depth map.

An imaging unit 20 has a configuration in which an identical polarization pixel block made up of a plurality of pixels with an identical polarization direction is provided for each of a plurality of polarization directions and pixels of respective predetermined colors are provided in the identical polarization pixel block. A correction processing unit 31 performs correction processing such as white balance correction on a polarized image generated by the imaging unit 20. A polarized image processing unit 32 separates or extracts a reflection component using the polarized image after the correction processing. By using a polarized image of the separated or extracted reflection component, for example, it is possible to generate normal line information with high accuracy.

An image capturing system (300), a kit for an image capturing system, a mobile phone, a use of an image capturing system and a method of configured a color matched light source are provided. The image capturing system obtains captured images having a substantially equal color reproduction in a portion illuminated by ambient light (L1) and a portion illuminated by a color matched light source (305). The image capturing system comprises an image capturing sensor (310), a controller (340) and the color matched light source. The color matched light source (305) comprises a first light source (320) and a second light source (330. The light emission spectra of the first and second light source are selected such that, in a color space of the image capturing sensor, a line between their color points is for a large part close to the locus line, while the first or second light source are at a distance from the locus line.
