    • An image processing method and an image processing apparatus converts a binary image into a grayscale image by increasing the size and information quantity of the binary image. The image processing method includes generating a plurality of lookup tables having multiple gray level values assigned to a predetermined pattern of the binary image such that the gray level is retrieved from the plurality of lookup tables depending on the context of the block being processed. The binary image may be converted into the grayscale image by applying the gray value of one of the plurality of lookup tables that corresponds to the context, such as the frequency components of the binary image. With this configuration, since the size and information quantity of an image can be reduced for transmission, it is possible to prevent deterioration of image quality when the image is restored, while also printing at a higher speed.
    • 图像处理方法和图像处理装置通过增加二值图像的大小和信息量将二进制图像转换成灰度图像。 图像处理方法包括生成具有分配给二进制图像的预定图案的多个灰度值的多个查找表,使得根据正被处理的块的上下文从多个查找表中检索灰度级。 可以通过应用与上下文相对应的多个查找表中的一个的灰度值,例如二进制图像的频率分量,将二进制图像转换成灰度图像。 利用这种配置,由于可以减小图像的尺寸和信息量以进行传输,所以可以防止当图像恢复时图像质量的劣化,同时也以更高的速度进行打印。

    • As a back panel of a view camera, the connector panel (100) attaches a digital single lens reflex camera to a view camera. The connector panel comprises a base panel (110), sliding panel (140), protruding pieces (130), and a mount ring (160). Two guiding strips (150) are attached to the base panel, allowing the sliding panel to be shifted side-to-side. This horizontal movement produces panorama photographs with no distortions and financial burden. Moreover, photographs can be taken at various angles as the mount ring, where the DSLR camera is attached, can rotate both clockwise and counter-clockwise. Lastly, the connector panel allows view camera's images to be saved as digital images through DSLR camera's imaging sensor, such as CCD and CMOS. Hence, view camera's images become easier to be saved, edited, and developed.
