31results about How to "Realistic impression" patented technology

The method enables a user to see how a selected product or how a plurality of selected products look in an immersive three-dimensional scene that resembles an actual or real property to be constructed or updated, or the relevant portions thereof. Since the images of the scene are displayed immersively, the user can view the scene from any vantage point and at any angle just as if the user were walking around the actual property. The user can thus obtain a realistic impression of how the new or changed property will look and the approximate cost of the improvement without first constructing a new structure or implementing changes to an existing structure. This enables the user to view many different possible options in order to decide which option is most desired. The user can feel confident that corresponding changes made to the real property be pleasing to the user.

A display system (20, 100, 300, 320) is provided for presenting images to a viewer (50) together with complementary peripheral surround- lighting (130). The system (20, 100, 300, 320) includes a monitor (20) for presenting the images to the viewer (50), and lights (100) for generating the surround- lighting (130) appearing in operation to the viewer (50) as at least partially peripherally surrounding the monitor (20). Moreover, the system (20, 100, 300, 320) further includes a controller (320) for energizing the lights (100) in response to properties of portions of the images presented on the monitor (20), and a sensor (300, 310) for sensing the surround-lighting (130) and / or environmental illumination and generating corresponding sensor signals (330). The controller (320) is arranged in operation to receive the sensor signals (330) for controlling the lights (100) for at least partially compensating the surround-lighting (130) to influence from the environmental illumination.

Provided are, among other things, systems, methods and techniques for processing an audio signal to add virtual bass. In one representative embodiment, an apparatus includes: (a) an input line that inputs an original audio signal in the time domain; (b) a bass extraction filter that extracts a bass portion of the original audio signal, which also is in the time domain; (c) an estimator that estimates a fundamental frequency of a bass sound within the bass portion; (d) a frequency translator that shifts the bass portion by a positive frequency increment that is an integer multiple of the fundamental frequency estimated by the estimator, thereby providing a virtual bass signal; (e) an adder having (i) inputs coupled to the original audio signal and to the virtual bass signal and (ii) an output; and (f) an audio output device coupled to the output of the adder.

Provided are, among other things, systems, methods and techniques for processing an audio signal to add virtual bass. In one representative embodiment, an apparatus includes: an input line that inputs an original audio signal; an estimator, coupled to the input line, that estimates a fundamental frequency of a bass sound within the original audio signal; a bass extraction filter, coupled to the input line, that extracts a bass portion of the original audio signal that is at least 1 octave wide and includes the fundamental frequency; a frequency translator, coupled to the bass extraction filter, that shifts the bass portion, in its entirety, by a positive frequency increment that is an integer multiple of the fundamental frequency estimated by the estimator, thereby providing a virtual bass signal; and an adder having 1) inputs coupled to the original audio signal and to the virtual bass signal and 2) an output.
