Abstract: A phase-based TOF system is operated with N?3 modulation frequencies fi. These frequencies can be changed during N time intervals that together define an exposure time for the TOF pixel array. Preferably N=3 and modulation frequencies f1, f2, f3 are used, where f1=?m1, f2=?m2, and f3=?m3, where m1, m2, and m3 are small integers co-prime to each other, and a is a coefficent. A first phase image is acquired during perhaps the first third of exposure time using f1, then for the next third of exposure time a second phase image is acquired using f2, and then f3 is used to acquire a third phase image during the last third of exposure time. Geometric analysis yields desired values for m1, m2, and m3 to unwrap and thus disambiguate phase. Identification of valid and invalid data is identified using dynamically adjustable error tolerances.

Abstract: Embodiments relate to systems and methods for dynamic sharpness control in system using binary to continuous tone conversion. Image data can be processed in the image path of a copier, printer, or other device to enhance sharpness based on user settings. The image can originate in a high-resolution and/or high-color format. The user can select sharpness values to provide better rendered detail. A front-end high-pass 2D filter can be adjusted in response to the settings. A binarized version of the image data is produced in the downstream path. At the back of the image path, the image would conventionally be sent through a binary data to extended contone (BDEC) low-pass filter, set to a fixed level, to produce contone output, counteracting the user's sharpness settings. Instead of applying a fixed back-end filter, that stage can be dynamically adjusted to correspond to the user's sharpness settings, reducing the low-pass effect proportionately.
