    摘要: Provided is an information processing apparatus that includes a transformation matrix calculation section, a scale calculation section, and an input display generation section. The transformation matrix calculation section calculates a transformation matrix that converts the coordinates of an input position of an input device within a projection region projected from a display apparatus from the coordinates of an image coordinate system of a sensor apparatus having detected the input position to the coordinates of a screen coordinate system of the display apparatus. The scale calculation section calculates a scale correction value for a display mode of the locus of the input position in reference to distance information regarding the distance between the display apparatus and the input position. The input display generation section generates an input image depicting the locus of the input position through the use of the transformation matrix and the scale correction value.

    摘要: A projection system includes a light source configured to emit a light in response to an image data, a phase light modulator configured to receive the light from the light source and to apply a spatially-varying phase modulation on the light, thereby generating a projection light and steering the light on a reconstruction field, wherein the reconstruction field is a complex plane on which a reconstruction image is formed, and a controller configured to control the light source, control the phase light modulator, initialize (401) the reconstruction field to an initial value, and iteratively for each of a plurality of subframes within a frame of the image data: set (402) the reconstruction field to the initial value for the first iteration or set (402) the reconstruction field to a subsequent-iteration reconstruction field value for any subsequent-iteration, map (403) the reconstruction field to a modulation field, wherein the modulation field is a complex plane of the phase light modulator which modulates a phase of the light, set (404) an amplitude of the modulation field to a predetermined value, and map (405) the modulation field with the amplitude set to the predetermined value, to a subsequent-iteration reconstruction field, wherein the controller is further configured to provide (408) a phase control signal based on the modulation field mapped with the last iteration to the phase light modulator.
