Abstract: PURPOSE: To reduce the amounts of compressed data indicating an original image by selecting extracting the bell signals of the original image stored at the bell positions of an input image buffer after dividing them into those at every other bell position and the other at the residual bell positions, and preparing compressed data. CONSTITUTION: An input image buffer 24A stores bell signals indicating an original image at bell positions. First compressed data indicating the bell signals stored in every other bell position in the buffer 24A and second compressed data indicating the residual bell signals are generated by a sampling unit 25 and a compressing/extending unit 26, and transmitted through a buffer memory 7 and a transmission line 6 to a buffer memory 3 of a host processor 1, and stored in a data memory 4 under the control of a control unit 5. The compressed data are extracted from the data memory 4, extended through the buffer memories 3 and 7 by the compressing/extending units 26 and the sampling unit 25, and an output image buffer 24B stores the reproduced first bell signals and second bell signals at each bell position.

Abstract: PROBLEM TO BE SOLVED: To provide a control method for a wireless LAN module for efficiently exchanging data. SOLUTION: First of all, it is decided whether or not a power source for supplying power is an AC adapter (step S201). When the power source is the AC adapter, data are exchanged (step S206). When the power source is not the AC adapter, on the other hand, the state of a link with an access point is measured (step S202) and further, when a radio wave strength is lower than a threshold as a result of measurement, a channel search is carried out (step S204) so that data are transmitted/received to a new access point (steps S205 and S206). In such a control method, when the power source is the AC adapter, data can be continuously exchanged without measuring the link state or carrying out the channel search.

Abstract: PROBLEM TO BE SOLVED: To provide a control method for radio LAN module capable of suppressing consumption power. SOLUTION: The control method comprises a step S201 of scanning an access point, a step S205 of setting a scanning time interval T up to the next scanning to t1 if communication with the access point is available, and a step S215 of setting the time interval T to t2 longer than t1 if the communication is not available. The control method further comprises a step S207 of determining whether power is supplied from an AC power supply or not if the communication is available, a step S209 of setting drive mode of the radio LAN module to a normal mode if it is determined that the power is supplied from the AC power supply, a step S210 of setting a power saving mode if not from the AC power supply, and a step S217 of setting the drive mode to a deep sleep mode if the communication is not available.

Abstract: PURPOSE:To attain the conversion of picture elements at a high speed by adding the value -N to the sum total value to count up an address which points the storage position of an output buffer and then adding the value M to the sum total value to count up an address which points the storage position of an input buffer respectively. CONSTITUTION:A means which checks whether the sum total value is negative or not produces a 1st signal showing that the sum total value is not negative and a 2nd signal showing that the sum total value is negative. The picture element data stored in the storage position of an input buffer 2 pointed by an address counter 7 is stored, i.e., moved to the storage position of an output buffer 3 pointed by an address counter 8 in response to the 1st signal. Then the sum total value is updated by adding the value -N to the sum total value. The value M is added to the sum total value in response to the 2nd signal so that the sum total value and then the address of the storage position of the buffer 2 are updated. As a result, the picture elements can be converted at a high speed.
