摘要： PURPOSE:To obtain a reproduced picture having its contrast corrected optionally by preparing plural types of gradation characteristic curve data and designating a level range of said data for production of the gradation correction data. CONSTITUTION:A CPU 13 of a gradation correcting part 1 reads the designated gradation characteristic data out of a ROM11 based on a selection instruction to store the data into a RAM12 and also to transfer it to a control part 3. Then the CPU13 produces the gradation correction data from the data on a gradation characteristic curve in accordance with a correcting level range included in the selection instruction received from the part 3. In other words, the CPU13 performs an arithmetic operation to change an input level range (a) of a gradation characteristic curve A into a designated level range (b). Then the obtained output level data on a gradation correcting curve B corresponding to the curve A is stored in the RAM12 and at the same time sent to the part 3. The part 3 gives both input and output levels of the gradation correction data to a display part 4 to show them in the image forms. Thus the correction picture data 15 of corrected multi-gradation is obtained.

摘要： PURPOSE:To wait for the release of holding in an on-hook state by a held extension subscriber by storing a holding set extension subscriber number and a held extension subscriber number and calling back the held extension subscriber after a holding set extension subscriber cancels holding. CONSTITUTION:When an extension subscriber (STA) 1 sets the holding of connection to an STA 2 while the STA 1 and STA 2 speak each other, a central control unit (CC) 8 stores the extension number information of the STA1 and STA2 in a main memory 9. When a holding cancel operation is executed by the STA 1 in this state, according to the extension number information of the STA 1 and 2 read out from the MM 9, the CC 8 transmits a ringer tone from an audible tone transmitter (TNG) 5 to the STA 1 and transmits a ringer tone from a ringer tone transmitter (RG) 7 through an extension subscriber circuit (LC) 5 to the STA 2 so as to call the STA 2.

摘要： PURPOSE:To attain the setting of a callback at the arrival of a dial-in call by allowing a caller setting the callback to make an exchange recognize and store its own subscriber number based on dial information. CONSTITUTION:A central controller 6 reports it to a caller 3 when a called extension subscriber 1 is busy or in the lockout state at the time of arrival of a dial-in call, and requests dialing of a special number for callback setting, a toll station number of a caller, a local number and a subscriber number of the caller when the setting of callback is desired, and stores the numbers. After the called extension subscriber is restored, the called extension subscriber 1 is called and after the reply of the called extension subscriber 1, the setting of the callback is informed and the called extension subscriber 1 is connected to a main wire trunk 10 and the toll station number, the local station number and the subscriber number of the caller received and stored by the caller 3 are sent to a telephone network.

摘要： PROBLEM TO BE SOLVED: To provide a caller call back system for a communication terminal which attains knowing the calling source of an incoming call by a callee's communication terminal though the callee does not respond to the call and which automatically calls back to the caller of the calling source. SOLUTION: When a prescribed condition to the incoming call to a multi- function communication terminal 1 (Calling continues over a prescribed time 'T', the callee is under communication and the like.) is generated, CPU 8 stores caller information in an area corresponding to caller information 2n corresponding to the multi-function communication terminal 1 of a caller information memory part 20 and lights a key light emitting part 12 corresponding to the calling key 13 of the multi-function communication terminal 1. On the other hand, CPU 8 reads caller information from the caller information memory part 20 based on the depressing operation of a calling key 13, picture-displays it on the picture display part 11 of the multi-function communication terminal 1 and when a prescribed dial key is depress-operated during displaying caller information on the picture display part 11, executes automatic dial calling based on this caller information.

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor memory of which the miniaturization can be attained by decreasing the number of pads, and its testing method. SOLUTION: A fuse F1 is cut off to perform normal operation in a SSTL mode. Also, in a normal operation, for example, voltage of 1.5 V is supplied to a pad PAD1. Consequently, as HIGH is outputted from a switch SW2 through a switch SW1 and a resistance element R1, a switch SW3 outputs a ground potential. A switch SW4 outputs voltage of the pad PAD1 to a switch SW6. At the time, as the switch SW6 is fixed to a SS side, voltage of the PAD1 is outputted from the switch 6 as a reference potential VREF. On the other hand, voltage generated by a reference potential generating circuit 1 is outputted as a reference potential VREF0. Therefore, in normal operation in the SSTL mode, the reference potential VREF0 is a voltage generated by the reference potential generating circuit, and the reference potential VREF is 1.5 V supplied to the pad PAD1.
