Abstract
The present invention discloses a motion image data generator, a system using motion image data, and methods relating to the generator and the system. The motion image data generator comprises: a photo sensor for capturing an image and converting it to digital image data; and a motion detection and processing circuit coupled to the photo sensor for comparing two digital image data outputted from the photo sensor to determine whether there is an object moving, and generating a corresponding output. In determining whether there is a movement, an object which keeps moving by a fixed frequency is filtered out.
Claims28
A motion image data generator comprising:
- a photo sensor for capturing an image and converting it to digital image data;
- and
- a motion detection and processing circuit coupled to the photo sensor for comparing two digital image data outputted from the photo sensor to determine whether there is an object moving, and generating a corresponding output.
An optical automatic power management system comprising:
- a motion image data generator including:
- a photo sensor for capturing an image and converting it to digital image data;
- and
- a motion detection and processing circuit coupled to the photo sensor for comparing two digital image data outputted from the photo sensor to determine whether there is an object moving, and generating a corresponding output;
- and
- a power management circuit coupled to the motion image data generator for determining whether to enter a power-saving mode according to the output from the motion detection and processing circuit.
A method for generating a motion image data, comprising:
- capturing an image;
- converting the captured image to digital image data;
- comparing two of the digital image data;
- generating a motion data according to the comparison of two of the digital image data;
- and
- generating motion image data according to the digital image data and the motion data.
A motion image data comprising data of plural pixels, wherein every pixel data includes X-bit image data and Y-bit motion data, where X and Y are positive integers.
A method for processing an image with only one single image buffer, comprising:
- providing a single image buffer;
- storing a first image data in the single image buffer;
- receiving a second image data and comparing the second image data with the first image data stored in the single image buffer;
- when the difference of the two image data is lower than a predetermined threshold, keeping the image data in the image buffer without updating it;
- and
- when the difference of the two image data is higher than the predetermined threshold, storing a third image data in the image buffer.
