Abstract: In a video monitoring system including HD and SD cameras, the system includes, on the transmitting side, a division/rotation processing unit for dividing an SD image into multiple divided images horizontally and performing a process for rotating the divided images by 90 degrees to the left, an image insertion unit for arranging and superimposing the divided images in a text telop region of an HD image, and a HD encoder for compressing and transmitting the HD image with the SD image superimposed. The system further includes, on the receiving side, a HD decoder for expanding the received HD image, and an output image processing unit for extracting the multiple divided images of the SD image and rotating these images by 90 degrees to the right, sorting and combining these images to reproduce the SD image, and outputting the expanded output HD image and the reproduced output SD image.

Abstract: It is determined based on processing to be performed on image data generated by reading by a first reading unit and a second reading unit, whether to separate, into image data of the first surface and image data of the second surface, image data that has been generated by reading by the first reading unit configured to read the first surface of a document, and the second reading unit configured to read the second surface of the document, and that includes the first surface and the second surface. When it is determined to separate the image data, the image data including the first surface and the second surface is separated into the image data of the first surface and the image data of the second surface.

Abstract: A converting apparatus includes a plurality of decoders, and a plurality of pieces of decoded data respectively corresponding to a plurality of pieces of compressed image data are generated. A switcher is configured to output the plurality of pieces of decoded data, by every predetermined amount, in association with an identification code of a corresponding portion of the plurality of pieces of compressed image data as process target data, and switch a destination decoder among the plurality of pieces of decoders every time when the predetermined amount of process target data is output. A converter is configured to apply an inverse quantization process and an inverse frequency conversion process to the predetermined amount of process target data. Each of the pieces of sub-image data converted by the converter is stored in the storage area corresponding to the identification code associated with the each of the pieces of sub-image data.
