Embodiment
See also Fig. 2, Fig. 2 is the functional block diagram of interactive apparatus 30 of the present invention.Interactive apparatus can be a mouse or an interacting toys (interactive toy).Interactive apparatus 30 comprises a processing module 44 and a control circuit 54.Processing module 44 is a chip.Processing module 44 comprises an image sensor 42, its can be a Charged Coupled Device (charge-coupled device, CCD) or a CMOS optical sensor, to be used for most digital pixel (pixel) signals of acquisition.Most pixel signals that produce are sent to processing module 44.Processing module 44 comprises a substrate 41, an evaluation unit 45, a computing unit 46 and transmission interface 48,52.Image sensor 42, evaluation unit 45, computing unit 46 and transmission interface 48,52 all are formed in the substrate 41.
See also Fig. 3, Fig. 3 is the synoptic diagram of most image frames.Each picture (picture) can be combined by most picture element signals.For instance, concerning the picture of a 800*600 size, need 480,000 picture element signals to combine altogether.Image sensor 42 promptly is to be used for producing most picture element signals.And most picture element signals that produce are sent to after the evaluation unit 45, and evaluation unit 45 will be judged the various parameters of each image according to most picture element signals.With target picture 120 is example, the decision show state of destination object 100 on target picture 120 can determine by several image parameterss, such as parameters such as coordinate, area (size), color parameter, directivity (orientation) and border (boundary), the object number of endpoint of destination object 100 on target picture 120, object length breadth ratios.For instance, destination object 100 can be considered the set of the picture element signal with same hue parameter, and evaluation unit 45 can be judged the parameters such as size, directivity border and GTG value of destination object 100 in target picture 120 according to number with same pixel signal and coordinate.Parameters such as evaluation unit 45 all right decision objects number of endpoint and object length breadth ratio.For instance, if destination object 100 is rectangles, then can also to determine the object number of endpoint be 4 to evaluation unit 45, and the length breadth ratio of this rectangular object.In other words, when static image system of parameters destination object 100 is in static the demonstration, can be for the parameter that measures.
In addition, general so-called dynamic image is a succession of continuous image sequence in fact, yet because have a kind of existing picture of persistence of vision on the human vision, so can produce the illusion of the image that links up.And in this kind dynamic image, because the time interval between picture is very little, so several indifferences between the picture that faces mutually are the change in location of picture material mostly.If when showing a dynamic image, most the picture element signals of must constantly recombinating in theory just can present continuous image.Yet, in general, on same image frame, have some common characteristics, perhaps be on the color, perhaps be on how much, or the further feature value obtain.Remove the mode of the redundant information on these spaces, will identify element important in the picture exactly, and remove repetition and do not have the element of demand.Please continue to consult Fig. 3, target picture 120 is to be distinguished into a plurality of objects, and each object can be any size.Each object in the middle of the target picture 120, be according to its with time shaft on difference between a object in the middle of the last picture 110, or and the central object of back one picture 130 between difference encode.With a destination object 100 carry out matching ratio to the time, can compare one by one to the object to be compared of all similar sizes in the search area 115 of last picture 110, or to a search area 135 of back one picture 130 in the object to be compared of all similar sizes compare one by one.In Fig. 3, after comparison, in the middle of all objects to be compared of last picture 110 and back one picture 130, find out is a references object 150 with destination object 100 difference minimums.The displacement difference that references object 150 and destination object are 100 is dynamic vector (motion vector).Computing unit 46 can see through above-mentioned mode and determine dynamic vector between each object.
After evaluation unit 45 and computing unit 46 obtain the correlation parameter of image, will respectively these image parameterss be transmitted and give transmission interface 48,52. Transmission interface 48,52 can be an asynchronism transceiver (universal asynchronous receiver/transmitter, UART) interface.Compared to synchronous concatenation transmission (synchronous parallel transmission), it is little that asynchronous serial (asynchronous serial) transmission has a volume, advantages such as cheap and long transmission distance.For instance, UART Universal Asynchronous Receiver Transmitter is a kind of a kind of asynchronous serial/parallel data converter that includes the data transmission between the serial type device (serial device) that is used for controlling this interactive apparatus 30 (or a processor) and is connected with interactive apparatus 30.More particularly, the function series of interactive apparatus that UART provides 30 is similar in appearance to data termination equipment (the data terminal equipment such as RS-232, DTE) the data function of exchange that is provided, so that interactive apparatus 30 can see through as universal serial bus (universal serial bus, serial type bus USB) and the mutual swap date of serial type device.
Except mentioned before UART (RS232 is a kind of of UART), transmission interface 48,52 also can be I
2C (inter-IC) and USB etc.I
2C is a kind of agreement that sees through two two-way (send and receive) transmission line (serial data line SDA and serial clock pulse line SCL) with data transmission.Because I
2The principle system of conversion such as C and USB serial data and data side by side is similar in appearance to the UART conversion serial data and the principle of data side by side, and is all this field person and knows, so do not repeat them here.
In other words, first transmission interface 48 or second transmission interface 52 can be UART interface, I
2At least a interface in the serial transmission group that C and USB constituted.
At last, control circuit 54 is after receiving static parameters such as the dynamic vector (motion vector) that transmitted by transmission interface 48,52 or the coordinate of object 110, size (size), color parameter, directivity (orientation), border (boundary), object number of endpoint, object length breadth ratio, can utilize the coding of each object in the last picture 110, the dynamic vector and the static parameter that cooperate each object in the target picture 120 are to reduce target picture 120.Or control circuit 54 is done further other processing according to these parameters, with the operation of control interactive apparatus 30.
Among another embodiment, first transmission interface 48 of the data that responsible transmission evaluation unit 45 is produced can be integrated into same interface with second transmission interface 52 of the dynamic vector that responsible transmission computing unit 46 is calculated.
For the interactive apparatus of optical mouse and so on,, pay much attention to for the shift position of cursor (can be considered an object) because optical mouse is a simple cursor (cursor) control device.So the parameter of the size of the imaged object that is determined for evaluation unit 45 and directivity and so on does not need especially, relatively payes attention to the dynamic vector that computing unit 46 is determined on the contrary.Therefore among the 3rd embodiment, processing module 44 can be at the device of optical mouse and so on, only design image sensor 42, computing unit 46 and second transmission interface 52 are formed in the same substrate 41, and do not need the evaluation unit 45 and first transmission interface 48 also together are formed in the same substrate 41.
Among the 4th embodiment, processing module 44 can only be formed at image sensor 42, evaluation unit 45 and first transmission interface 48 in the same substrate 41, and does not need the computing unit 46 and second transmission interface 52 also together are formed in the same substrate 41.
Compared to known technology, the processing module 44 that the present invention includes image sensor 42, evaluation unit 45, computing unit 46, transmission interface 48,52 can be integrated into the single-chip that is positioned at same substrate 41.Evaluation unit 45 can be judged the coordinate of most picture element signals, and determines the image parameterss such as size, border, directivity and color parameter of imaged object according to pixel coordinate.And computing unit 46 can calculate dynamic vector via most the signal of video signal that image sensor 42 is transmitted in advance.Simultaneously transmission interface 48,52 is to utilize the UART interface or other any serial transmission interface transmits the image parameters that these calculate.So use the interactive apparatus 30 of the designed chip of the framework of processing module of the present invention, because this chip can calculate these image parameterss in advance, utilize general serial transmission interface (as UART) that parameter is transmitted simultaneously and give control circuit 54, no longer need additionally to go to calculate these complicated parameter so be positioned at the control circuit 54 of rear end, also therefore reduce the complexity of Circuit Design, make that the use elasticity of control circuit 54 of interactive apparatus 30 is bigger, and shorten the time-histories of interactive apparatus exploitation.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to the covering scope of patent of the present invention.
