Abstract:
The image processing apparatus transforms orthogonal transform coefficients into a predetermined number of bits for each spatial frequency, rearranges quantized data for each spatial frequency to an arrangement with spatial frequency band portions, thereby generates bit serial data that the quantized data of the same spatial frequency band exists successively over adjacent blocks, and compresses the bit serial data.
Abstract:
The present invention calculates a product of the present sampling data by the sampling data 1 data unit ahead through multiplier 14, adds up product values calculated for every sampling by going back to the time point 1 data unit ahead through adder 16 and detects a reference timing with regard to a CP signal using the addition value.
Abstract:
A communication apparatus is connected to a terminal apparatus via a network. The communication apparatus includes a memory that stores image data and a storage period of the image data and a checker that determines whether a storage time of the image data exceeds the storage period time. A deleter deletes image data based on a determination by the checker section and a server transmits an instruction for changing the storage period to the terminal apparatus in accordance with a request by the terminal apparatus, wherein the storage period is changeable from the terminal apparatus.
Abstract:
A multifunctional printer is provided with a main CPU that controls the entire apparatus, main power unit that supplies power to the main CPU, sub CPU that shuts down the power supply from the main power unit to the main CPU at a predetermined condition and restores the power supply from the main power unit to the main CPU upon detecting a factor canceling the power supply shut-down, PC interface board that informs the sub CPU about the factor canceling the power supply shut-down upon detecting a printing request from a PC, and sub power unit that supplies the power to the sub CPU and PC interface board separately from the main power unit.
Abstract:
A center and remote sides are connected via a line and perform an initialization sequence to set a transmission speed and to detect gain characteristics of a signal received during the initialization sequence at both sides. Both center and remote sides then inform each other of the detected gain characteristics and correct gain characteristics of future transmission signals based on the informed gain characteristics. Therefore, it is possible for a sender side to perform a gain correction that raises gain amounts of transmission signals according to a decay rate, and for a receiver side to maintain the reception level, which is more than a predetermined value, thereby providing a high-speed data rate.
Abstract:
A toner container holding device that engages with a toner container having a first opening to supply toner to a developing device is provided. The toner container holding device includes a container holder that detachably holds the toner container and has a second opening at a position coinciding with the first opening, and a hopper frame that stores the toner received from the toner container. A first seal member if provided between the toner container and the container holder, when the toner container is engaged with the container holder. A second seal member is provided between the container holder and the hopper frame. The container holder has an opening portion spaced from the first and second seal members.
Abstract:
The present invention provides a process cartridge includes a first unit and a second unit separable (detachable) from the first unit. The first unit includes a photosensitive member, a developing unit that forms an image on the photosensitive member, and a cleaning unit that collects residual toner from the photosensitive member. The second unit includes a toner hopper unit that supplies toner on the photosensitive member, and a waste toner box that stores the collected residual toner. The developing unit engages with the toner hopper unit so as to engage
Abstract:
A communication apparatus is connected to a terminal apparatus via a network. The communication apparatus includes a receiver that receives e-mail data via the network, a memory that stores the received e-mail data, and a generator that generates management data corresponding to the stored e-mail data, as a structured document. A server transmits the management data to the terminal apparatus when a request for the management data is received from the terminal apparatus. The management data is displayable at the terminal apparatus, and the terminal apparatus designates the management data to delete e-mail data in the memory, corresponding the designated management data. A deleting section, when the designated management data and a request for deletion are received from the terminal apparatus via the network, deletes e-mail data stored in the memory, corresponding to the designated management data.
Abstract:
An Internet communication control apparatus and its transmission control method is provided, to which communication terminals such as facsimile apparatuses and/or telephones are connected, that is connected to the Internet to perform transmission/reception with other communication terminals. When an off-hook state of a connected communication terminal is detected upon transmitting, a setting for dial tone signal reception is prepared, and the received signals are converted to a destination number. By checking the corresponding table, the destination number is converted into a destination address, and according to the content of the table, whether the communication is for facsimile transmission or telephone call is determined. According to the result of the determination, a facsimile process or telephone process is selectively performed so that the transmission operation does not seem abnormal and complicated.
Abstract:
A communication apparatus includes a scanner configured to scan a document to obtain binary image data, an adder that adds paper size information to the obtained binary image data and a converter that converts the binary image data, including the paper size information, into e-mail data. A transmitter transmits the converted e-mail data, including the paper size information to a destination terminal over a network so that the destination terminal can determine whether to downsize the binary image data in the e-mail data in accordance with the paper size information.
