Abstract: An apparatus detects movement of a target object, estimates a control quantity for first feedback control for the target object at a first period, based on a detection signal, and estimates a first state quantity of the target object and a second state quantity obtained by time differentiation of the first state quantity in order to perform second feedback control for the target object at a second period shorter than the first period, based on the detection signal. The apparatus generates a first operation quantity for the first feedback control, based on the estimated control quantity, generates a second operation quantity for the second feedback control, based on the estimated first and second state quantities, and determines an output value, based on a result of comparing the second operation quantity with a maximum value of the first operation quantity.

Abstract: Techniques for interactively determining/visualizing the color content of a source image and how the corresponding image data is mapped to device colors are described herein. For example, the color content of a digital image can be converted between different color spaces to identify gamut limitations of an output device (e.g., a printing assembly), discover color(s) that cannot be accurately reproduced, etc. Color space conversions enable the transformation of the color content of the digital image from device-specific colorants to a device-independent representation (and vice versa). In some embodiments, these transformations are facilitated using lookup tables that are implemented in graphical processing unit-resident memory.
