In addition, when the image data corresponding to the new image data provided from the camera 30 is not found in the memory 80, the controller 90 reads an input request message from the memory 80. The speaker 50 is provided. When the new audio data is provided through the audio codec 70, the controller 90 stores the new audio data in the memory 80 together with the new video data provided through the interface 40. The storage completion message is read from the memory 80 and provided to the voice codec 70. On the other hand, when the storage of the new video data / new audio data fails, the controller 90 reads the storage failure message from the memory 80 and provides the audio codec 70.

Figure 4 is a flow chart for explaining the operating state of the educational toy for explaining the input image according to the present invention configured as described above. Referring to Figure 4, according to the educational toy according to the present invention, first, when the image of the subject is projected on the mirror 20, the camera 30 captures an image substantially the same as the image projected on the mirror 20 (S410). In this case, the image sensor 32 of the camera 30 generates new image data corresponding to the captured image (S420), and provides the generated new image data to the controller 90 through the interface 40. do.

In this case, the controller 90 sequentially searches for a plurality of image data stored in the memory 80 based on the new image data provided from the camera 30 (S430), and within the predetermined tolerance range, It is checked whether image data corresponding to the new image data exists in the memory 80 (S440). There are various ways to check whether the image data corresponding to the new image data exists in the memory 80 within the error range, for example, it can be done through the Motion Estimation technique used in MPEG, which is obvious to those skilled in the art. That's one thing. Specific papers related to the prior art are as follows. [1] B. Liu, A. Zaccarin: "New Fast Algorithms for the Estimation of Block Motion Vectors", IEEE Trans. on Circuits and Systems for Video Technology ", Vol. 3, No. 2, April 1993, pp148-157 [2] unju Baek, Hwang-Soek Oh and Heung-Kyu Lee:" Block-matching criterion for effiecient VLSI implementation for motion estimation ", IEE Electronics Letters, 20th June 1996, vol. 32, no. 13, jun 1996, pp 1184-1185" Then, in the checking step (S440), image data corresponding to the new image data is stored in memory 80 In the case of the detection, the controller 90 reads the audio data corresponding to the detected image data from the memory 80 (S450) and provides it to the audio codec 70. Then, the voice codec 70 converts the voice data provided from the controller 90 into a voice signal (S460), inputs it to the speaker 50, and the speaker 50 outputs the input voice signal (S470). ). In this case, the audio signal output from the speaker 50 is a description of the meaning (or use) and / or title of the image projected on the mirror 20.

On the other hand, in the checking step (S440), when it is confirmed that the image data corresponding to the new image data does not exist in the memory 80, the controller 90 reads an input request message from the memory 80 The voice codec 70 is provided. Then, the voice codec 70 converts an input request message into a voice signal and then inputs it to the speaker 50, and the speaker 50 outputs a voice signal corresponding to the input request message (S480). Subsequently, when the parent (or teacher) explains the meaning (or use) and / or title of the new video data to the microphone 60, the microphone 60 collects a new audio signal (S482) and the audio codec ( 70).

Subsequently, the voice codec 70 converts an input new voice signal to generate new voice data (S484), and provides the generated new voice data to the controller 90. In this case, the controller 90 combines the new voice data provided from the voice codec 70 together with the new image data provided from the camera 30 and stores the new voice data in the memory 80 (S486).

Then, the controller 90 checks whether the storage of the new video data / new audio data is completed (S488). In the checking step (S488), when the storage of the new video data / new audio data is completed safely, the controller 90 reads a storage completion message from the memory 80, and through the audio codec 70, a speaker Provided by 50. At this time, the speaker 50 outputs a sound indicating the completion of storage (S490), and informs the parent (or teacher) who input the new description that the storage of the new image data / new audio data is completed. In other words, the memory 80 is updated. On the other hand, if it is confirmed in the inspection step (S488) that the storage of the new video data / new audio data has failed, the controller 90 reads the storage failure message from the memory 80, and the voice codec 70 Through, to provide to the speaker 50. At this time, the speaker 50 outputs a voice indicating a storage failure (S492), and informs the parent (or teacher) that the storage of the new image data / new audio data has failed.
