A digital picture signal processing apparatus is disclosed, that comprises a picture processing means for compressing a captured digital picture signal, and a mode designating means for generating a signal that designates a picture processing operation of the picture processing means to a first mode or a second mode, wherein when the first mode is designated, the picture processing means generates first compressed picture data of which the digital picture signal is compressed by a non-inversible encoding method, and wherein when the second mode is designated, the picture processing means generates second compressed picture data of which the digital picture signal is digitized and the digitized picture signal is compressed by an inversible encoding method.

Digital picture signal processing apparatus, method thereof, digital picture recording apparatus, method thereof, transmitting method thereof, and data record medium thereof

In an image data communication system, a digital image recording apparatus captures a desired still image or moving video image. For a color still image, the digital image recording apparatus compresses the image based on JPEG to create a color GIF (graphics interchange format) file. This file is converted to image data having an amount of data which can be processed with a portable telephone or a portable information terminal. An image sender transfers the image data generated from the digital image recording apparatus to an image distribution server. The image distribution server records the image data in an internal recording apparatus and notifies a recipient that the image is ready for distribution by sending, for example, an e-mail message to the portable telephone or the portable information terminal.

Image data communication system and method thereof, and image pickup apparatus and image data processing method

When an animation mode is designated, still picture data that has been photographed or discretely read from a record medium is compressed in a subtractive color process and a data compressing process corresponding to the LZW method. The compressed data is converted into an animation GIF file of which still picture data is combined in the time sequence and it is correlatively displayed on the time base. When an animation mode completion command is input or the size of the GIF file becomes a recordable size of the external storage medium, the GIF file data is written to the external storage medium. In addition, after a photographed still picture is recorded to the external storage medium, an animation can be created. In addition, an animation GIF file can be created using a plurality of still pictures recorded in the external storage medium. In addition, an animation GIF file that has been created can be edited.
