Abstract: A digital camera has an image sensor system, a first compression system, a frame buffer, a first decompression system, and an image processing system. The image sensor system provides n pixels of initial image information. The n pixels each have m bits of intensity information of one color from three component colors. The initial image information is thus nnullm bits in size. The first compression system compresses the nnullm bits of the initial image information into r bits of secondary image information. The frame buffer is at least r bits in size for storing the secondary image information. The first decompression system decompresses the r bits stored in the frame buffer to provide tertiary image information. Finally, the image processing system accepts the tertiary image information to generate processed image information. The pixels of the processed image information each have intensity information for each color of the three component colors.

Abstract: Data is received from a memory, which includes bitmap images, for output on an output device. The images may be stored in compressed or uncompressed form. The operating system, application or generic graphics environment program interface, queries the printer driver for the types of image compression formats supported by the printer. If the image is available in a compatible compressed format, that compressed image is read from memory. Alternatively or in addition, the best possible compression format supported by the printer is selected from the formats available in the printer driver. The image is then loaded in a printer compatible compression format or compressed using the selected format. The image is spooled in the selected compression format. The image file may be spooled as a raw file or metafile depending on the embodiment used. When needed by the printer or video display, the spool file containing the compressed image is accessed from storage, and the compressed image is sent directly to the printer or video display without allocating memory for decompressing the bitmap image or decompressing the image.

Abstract: This invention is a digital still camera having a coded data quantity monitoring circuit (9). This monitoring circuit (9) detects the quantity of data of an image signal compressed by a JPEG compression circuit (7). When a CPU (10) judges that the quantity of data detected by the coded data quantity monitoring circuit (9) is equal to or more than a maximum coded data quantity S, first, an image pickup element (3) is caused to pick up an image of an object again and output a different image signal, and a quantization table to be used in a quantization circuit (21) is changed. Next, the different image data is compressed by being DCT-transformed by a DCT circuit (20), then quantized by the quantization circuit (21) and coded by a coding circuit (22). The compressed different image signal is recorded to a memory card (13). In this case, the different image signal is recorded into an area where an image signal has been recorded in advance on the memory card (13).

Abstract: A sender transforms scanned image data to binary compressed data with a fixed parameter, converts it to e-mail data, adds information indicating its local control system and identification information for a capability request to the e-mail data and sends the resultant e-mail data. When a transmission destination is an electronic mail device, the transmission destination prints the attached page of specific conditions after which communications between the sender and the receiver are terminated. When the transmission destination has the same control device as the sender, the transmission destination transmits a response message to the sender in which information indicating its local control method and a capability response are provided. The sender generates, from image data, binary compressed data whose image size, resolution and coding system are matched with the capability of the transmission destination, converts this binary compressed data to e-mail data and resends the e-mail data.

Abstract: A communications system receives fax image data encoded with a specific facsimile data format and carrying transmission codes having no relation with image contents, converts the received fax image data into Internet-fax data in a specific format, and transfers the Internet-fax data to an Internet terminal as an in-system terminal. The communications system includes a receiver to receive the fax image data supplied via a regular communications network, a comparator to compare an encoding mode for the received fax image data and an encoding mode for the Internet-fax data for the Internet terminal, a converter to add format data for the Internet-fax data to the fax image data with no decoding of the fax image data if there is a match in the comparison, for converting the format data-added fax image data into the Internet fax data, and a transmitter to transmit the converted Internet fax data to the Internet terminal.
