Abstract:
An image capture, conversion, compression, storage and transmission system provides a data signal representing the image in a format and protocol capable of being transmitted over any of a plurality of readily available transmission systems and received by readily available, standard equipment receiving stations. In its most comprehensive form, the system is capable of sending and receiving audio, documentary and visual image data to and from standard remote stations readily available throughout the world.
Abstract:
The presently claimed invention relates generally to methods and apparatus associated with steganographic encoding (e.g., data hiding). One claim recites a method including: obtaining plural-bit auxiliary information; and during communication between a first computer and a second computer over a network, modulating timing or phase of a clock signal generated by the first computer so as to steganographically hide the plural-bit auxiliary information in a communications signal sent between the first computer and the second computer. Of course, other claims and combinations are provided as well.
Abstract:
Images are captured and are stored (either in compressed or non-compressed form) in non-volatile storage at a predetermined quality or Q level. When the storage fills to a predetermined threshold, some or all of the images are compressed or recompressed to a lower quality, to make room for additional storage; i.e. new images may be captured and compressed at this lower quality or Q level, to minimize the rate at which the remaining storage is consumed; or all of the captured and stored images may be compressed or recompressed to this lower quality or Q level.
Abstract:
An image reading apparatus reads image information of an original document to produce image data having different data sizes. An image converting section converts the image information into a plurality of items of image data. A display section displays a plurality of items of information on the plurality of items of image data. A selecting section allows selecting of one of plurality of items of image data.
Abstract:
Methods are provided for an apparatus which encodes items of data by variable-length coding and which stores the encoded items of data in a memory, wherein a size of one of the items of encoded data is variable by varying a value of a control parameter of the variable-length coding. One method includes: determining an amount of available memory space in the memory; determining a value of the control parameter for the variable-length coding of the items of data; and determining a number of items of encoded data that can be stored in the available memory space, based on an upper limit of the size of one of the items of encoded data at the determined value of the control parameter.
Abstract:
A facsimile apparatus is disclosed that performs accurate and efficient facsimile transmission while obtaining accurate reception capacity information of each transmission destination. The reception capacity of each transmission destination is stored, together with the mail address, in a memory unit of the apparatus. When facsimile transmission accompanied by a delivery confirmation request is carried out, a main controlling unit causes the memory unit to store the transmission mode. If delivery confirmation mail from the transmission destination contains reception capacity information, the main controlling unit causes the memory unit to store it as the reception capacity information of the transmission destination. If the delivery confirmation mail does not contain reception capacity information but confirms that the communication has been properly completed, the transmission mode already stored in the memory unit is stored as a transmission enabling mode of the transmission destination in the memory unit.
Abstract:
An original document image is inputted as multi valued image data (original image data) from an input unit. The multivalued image data is binarized by a binary image generation unit. Then, layout analysis is performed based on the binary image data. Based on the layout information, a partial image having text-attribute is extracted and a partial image having non-text-attribute are extracted from the multi-valued image data. One of the partial images is encrypted, and the encrypted data is stored with the partial image that is not encrypted and the layout information.
Abstract:
An image forming apparatus including: a data generator to generate image data; an email writing unit to write an email including the generated image data; a user interface unit to display a user interface, which enables a user to select email transmission options, if the image data exceeds a file size limitation information of a mail server to receive the email; and a controller to control the email writing unit to write the email, according to the transmission option(s) selected through the user interface.
Abstract:
There is provided a method of determining an optimal image transmission method when image data is transmitted from an image supplying device 1 and 1′ to an image display device 2 and 2′, the method including: before the image data is transmitted after a transmission path from the image supplying device 1 and 1′ to the image display device 2 and 2′ is established, determining the image transmission method on the basis of correspondence table, which is previously prepared, such that the optimal image transmission method according to at least one of transmission path information and capability of the image display device 2 and 2′ acquired by the image supplying device 1 and 1′ is derived.
Abstract:
The present invention enables reduction in the amount of data of a document image while maintaining a layout of the document image, and enables suppression of image quality deterioration when reproducing the document image. An original document image is inputted as multivalued image data (original image data) from an image input unit. The multivalued image data is binarized by a binary image output unit. Then, layout analysis is performed based on the binary image data. With respect to text areas, character recognition is performed on the binary image, then the recognition data is outputted. With respect to non-text areas, the binary image data is used without further processing. With respect to a multivalued image, e.g., photographs or the like, the image data is compressed with an appropriate condition and stored.
