The present invention relates to a 3D time-of-flight camera and a corresponding method for acquiring information about a scene, in particular for acquiring depth images of a scene, information about phase shifts between a reference signal and incident radiation of a scene or environmental information about the scene. To increase the frame rate, the proposed camera comprises a radiation source (12) that generates and emits electromagnetic radiation (13) for illuminating said scene (2), a radiation detector (14) that detects electromagnetic radiation (15a, 15b) reflected from said scene (2), said radiation detector (14) comprising one or more pixels (16), in particular an array of pixels, wherein said one or more pixels individually detect electromagnetic radiation reflected from said scene, wherein a pixel comprises two or more detection units (161-1, 161-2, ...) each detecting samples of a sample set of two or more samples and an evaluation unit (18) that evaluates said sample sets of said two or more detection units and generates scene-related information from said sample sets, wherein said evaluation unit comprises a rectification unit (20) that rectifies a subset of samples of said sample sets by use of a predetermined rectification operator defining a correlation between samples detected by two different detection units of a particular pixel, and an information value calculator (22) that determines an information value of said scene-related information from said subset of rectified samples and the remaining samples of the sample sets.
