Description of the Invention: [Technical Field of the Invention] The present invention relates to an interactive system, and more particularly to an interactive system capable of improving image processing speed. [Prior Art] With the increasing popularity of video and audio multimedia, image digitization has gradually become a trend. In general, image sensors installed in digital video cameras (Digital Video Camcorder) and digital still cameras (Digital Still Camera) can produce higher quality digital images, so most of them are used in image recognition and fingerprint recognition. However, image sensors installed in digital cameras and digital cameras with lower resolution are often used in interactive toys to recognize the user's simple actions. For example, the current machine pet introduced on the market, its built-in camera can be used as the "eye" of the robot pet to sense the user's movements, and then the robot's built-in control circuit instructs the robot pet to make different instructions. . Please refer to FIG. 1. FIG. 1 is a schematic diagram of a functional block diagram of the interactive system 10 of the prior art. The interactive system 10 includes an image sensor 12, a microcontroller 14, and a parallel transmission bus 16. The image sensor 201141200 12 includes a complementary MOS sensing array 22 and an analog to digital converter (ADC) 24. The data sensed by the complementary gas oxy-half sensing array 22 is passed to an analog digital converter 24. Since the complementary MOS semi-sensing array 22 can sense a plurality of pixel data for forming an image, when a dynamic continuous image is captured, the complementary MOS semi-sense array 22 continuously generates pixel data of different images. And generate huge pixel data. In order to transmit such a pixel A, the image sensor η and the microcontroller 14 transmit the sensed pixel data through the parallel transmission bus 16 . The microcontroller 14 controls the operation of the vertical system 10 based on the obtained pixel data, the image, or the state of the object. However, the amount of data in the above sense is extremely large, and the rapid development of the transmission technology, so the catch of the serial transmission is no longer as good as the serial transmission = (10) the parallel implementation of the hardware architecture == transmission interface to receive the sense of shame (4) after the data It is still necessary to calculate the sub-range and Γ: off data: Since each application of the microcontroller 14 is applied to the micro-control of the silky gas, the micro=4 does not need to be complete and detailed. The image data only needs to be like the relative position of the object moving in the shirt, and the image sensor 12 of the previous technology is required to generate the image. If the user uses all the pixel data first, the data is collected: 'The microcontroller 14 has to deal with a heavy burden. This will result in the microcontroller 201141200. Moreover, the current image sensor 12 converts only the received optical signal into a single chip of the electrical signal. Therefore, such a single-wafer image sensor 12 is in need of improvement in the trend of circuit design that emphasizes system integration.

The image sensor 42 is configured to sense an optical signal from the reference device 4 to generate a plurality of pixel signals. When a pixel signal is generated, the pixel signal is transmitted to the estimating unit 45. Then, the estimating unit 45 determines whether the pixel signal conforms to a predetermined condition. If the pixel signal meets the preset condition, the neighboring pixels of the pixel signal that meet the preset condition are the same as the object according to the preset condition. New, estimate unit 45 static parameters of the object, such as seat weight ~, area, orientation, color, boundary, object end points and / or object aspect ratio. The color static parameters of the object include the average color, the color of the pixel signal at the center of gravity, and the color % of the pixel signal with the maximum brightness. The preset condition is a brightness between a first preset threshold (10) such as a grayscale value of 8〇) and a second preset threshold (for example, a grayscale value of 2〇〇), but the current month does not This is limited. Taking the target face (10) as an example, the display state of the private object 1 〇〇 on the target face can be determined by several static parameters. The center of gravity of the object 100 is determined by the following formula:

The estimating unit 45 determines the static parameters of the target object 1〇〇 at the target pupil surface 12, such as the area, the boundary, and the grayscale value, based on the number of substantially identical pixel signals and the corresponding coordinates. In addition, the estimating unit 45 can also determine the number of object end points of the target object 100 and the aspect ratio of the object. For example, assuming that the target object 1 is a rectangle, the estimating unit 45 will determine the number of object endpoints of the target object 100 to be 4, and the aspect ratio of the target object 1〇〇. In other words, the static parameter is a parameter that can be measured when the target object 100 is in a static display. After the relevant static parameters of the target object 100 are obtained, the estimation unit 45 transmits these static parameters to the transmission interface 48. The transmission interface 48 is a universal asynchronous receiver/transmitter (UART) interface. Compared to synchronous parallel transmission, asynchronous serial (J) (asynchronous serial) transmission has the advantages of small size, low price and long transmission distance. For example, a 'general asynchronous transceiver is a non-synchronous serial/parallel φ data converter for controlling an interactive system 30 (or a processor) and a serial device connected to the interactive system 30. Transfer data between. More specifically, the function of the interactive system 30 provided by the universal asynchronous transceiver is similar to that of the data terminal equipment (DTE) such as RS-232, so the interactive system 3 can Data is exchanged with the serial device through, for example, a universal serial bus (USB). 10 201141200 In addition to the UART mentioned above (RS232 is a type of UART), the transmission interface 48 can also be I2C (inter-IC) and USB. I2C is a protocol for transmitting data by transmitting and receiving bidirectional transmission serial data lines and serial clock lines. Since the principle of I2C and USB conversion serial data and parallel data is similar to the principle of UART conversion serial data and parallel data, it will not be described here. Therefore, the first transmission interface 48 can be at least one interface of the serial transmission/combination of the UART interface, I2C (inter_IC) and USB. Finally, after the control circuit 54 receives the static parameters such as object coordinates, area, orientation, color, boundary, number of object endpoints, and/or object aspect ratio transmitted by the transmission interface 48, The target facet 12〇 can be restored by using the code of each object in the facet 110 plus the static parameter of each object in the target facet 12〇. The color static parameter package of the object • contains the average color, the color of the pixel signal at the center of gravity, and the color of the pixel signal with the maximum brightness. In addition, the control circuit 54 can perform further processing based on these static parameters to control the operation of the interactive system. In contrast to the prior art, the present invention provides an interactive system 30 having a reference device 40. The reference device 4 is used to transmit and/or reflect a specific frequency spectrum (4) optical signal. The image sensor 42 is used to sense the light from the reference device 40 to generate a plurality of pixel signals. The estimating unit 45 determines whether the pixel signal 201141200 meets the -preset condition. If the pixel signal meets the preset condition, the adjacent pixels of the pixel signal that meet the preset condition are regarded as the same object' according to the preset condition and the static parameter of each object in each face is determined. Therefore, the control circuit 54 located at the back end no longer needs to calculate these complicated static parameters, and thus reduces the complexity of the control circuit design, so that the control system M of the interactive system 3 is more flexible and shortens the interaction. The development time of the system. The above description is only the preferred embodiment of the present invention, and the scope of the present invention is the same as that of the invention.
