Independent Claim
85 words
A method of scheduling operating modes of a video information analysis device, comprising the steps of: storing scheduling information, said scheduling information including a plurality of scheduling information portions each corresponding to a respective different future period of time, and each indicating an operating mode of said analysis device that has been selected for said period of time; and controlling said analysis device so as to operate in accordance with the selected operating modes during the periods of time indicated by the stored scheduling information.
Claim 78
Independent Claim
85 words
A method of scheduling operating modes of a video information analysis device, comprising the steps of: storing scheduling information, said scheduling information including a plurality of scheduling information portions each corresponding to a respective different future period of time, and each indicating an operating mode of said analysis device that has been selected for said period of time; and controlling said analysis device so as to operate in accordance with the selected operating modes during the periods of time indicated by the stored scheduling information.
Claim 79
Dependent Claim
61 words
A method according to claim 63, wherein said selected operating modes include a first mode in which said analysis device detects an illumination condition represented by video information analyzed by the analysis device and a second mode of operation in which said analysis device determines whether the video information analyzed by the analysis device represents a moving object crossing a perimeter.
Claim 80
Dependent Claim
199 words
A video information storage apparatus, comprising: video information source means for generating a dynamic video signal formed of a sequence of video signal fields, each of said fields representing a respective image in an image plane, said dynamic video signal having a time resolution corresponding to a field rate at which successive fields of said sequence are produced, said dynamic video signal also having a space resolution corresponding to a density at which pixels of said signal are formed in said image plane; signal processing means for receiving said dynamic video signal generated by said video information source means and for selectively varying at least one of the time resolution and the space resolution of the received dynamic video signal; user adjustable means for entering a control signal for controlling whether and to what degree said signal processing means varies said at least one of the time resolution and the space resolution of the received dynamic video signal, said signal processing means outputting a processed dynamic video signal having a time resolution and a space resolution at least one of which is determined in accordance with said control signal; and storage means for storing said processed dynamic video signal.
