Document Type and Number:
WIPO Patent Application WO/2015/135395
Kind Code:
A1
Abstract:
Image processing technologies, an image acquisition method and an image acquisition apparatus are provided. A method comprises exposing an image sensor, reading a charge on the image sensor and performing analog-to-digital conversion, where a charge of pixels on a partial region of the photosensitive sensor is read by means of pixel binning according to data characteristics of an image of a target scene, and obtaining a target image of the target scene according to the read charge. Local combination can be performed on at least two images of different image quality according to data characteristics of the images, so that the dynamic range and/or signal-to-noise ratio can be improved locally on the basis of presenting image details as fully as possible, that is, the image quality can be improved according to requirements.
