20100053326 | IMAGE SENSOR, THE OPERATING METHOD AND USAGE THEREOF - To solve the defect of the present image sensor used for obtaining both visible information and information indicating variation, such as low frame rate and being not applicable for portable apparatus, the present invention proposed an image sensor, operating method and usage thereof. The image sensor comprises an optoelectronic array, configured to convert optical signals of a first image and reference images at different moments into electronic signals, and the resolution of the optoelectronic array satisfying the requirement of visualization; a first module, configured to read the electronic signals of said first image by way of sampling, to read the electronic signals of each of said reference images by way of sampling, and to obtain the information indicating variation of the first image with respect to the reference images; and a second module, configured to read at least part of the electronic signals of one or more images, and to obtain at least part of visible information of the one or more images. The image sensor according to the present invention can output the visible information of the image at a suitable frame rate, and can also work at high frame rate and output the information indicating variation of the image, without consuming external resource and being especially applicable to the portable apparatus such as mobile phones. | 03-04-2010 |
