    • A CPU 36 of a light emitting unit 30 fetches ith bit of transmission information TX stored in a transmission data memory 33 in synchronization with a clock signal CK from a timing generator 35. The CUP 36 determines the bit value and fetches a first pattern sequence SA from a pattern data memory 44 when the bit is logic signal 1, and fetches a second pattern sequence SB from a pattern data memory 34 when the bit is logic signal 0, and outputs the first pattern sequence SA and second pattern sequence SB to a light emitting section 37. While, a CPU 39 of a light receiving unit 40 extracts a pixel area with a time sequence luminance variation pattern from a frame image captured into a capture image buffer 46, and binarizes the luminance variation pattern, and performs logic determination. A liquid crystal display 44 displays information of a light emitting area to be overlapped with a subject image.

    • A calligraphy/drawing camera image-captures a document and sends a resultant captured image to a personal computer (S101). The personal computer applies various image processes such as correction of various deformations including a trapezoidal deformation based on image information obtained from the captured image, a rotation process, a cut out process, etc. to the captured image (S102 to S104). The personal computer sends the processed image to a projector (S105). The projector projects the processed image on a screen (S106). Since the captured image is corrected based on the image information obtained from the captured image, not only correction of a trapezoidal deformation but also various other corrections can be done on the captured image.
    • 书法/绘图相机图像 - 捕获文档并将合成的拍摄图像发送到个人计算机(S101)。 个人计算机应用各种图像处理,例如基于从拍摄图像获得的图像信息,旋转处理,剪切处理等将各种变形(包括梯形变形)进行校正,以捕获图像(S 102至S104)。 个人计算机将经处理的图像发送到投影仪(S105)。 投影仪将经处理的图像投影到屏幕上(S106)。 由于基于从拍摄图像获得的图像信息来校正拍摄图像,因此不仅可以对拍摄图像进行梯形变形的校正,而且可以进行各种其他校正。
