摘要
The line memory controller of a camcoder is comprised of: an address controller (11) deciding a capacity of 1/2 line memories (15 and 16) to output a start/stop signals in accordance with it; a counter (12) generating an address signal (ADD) at a half rate of a main clock signal (CK) under a control of the address controller (11), and outputting 1/2 clock signal (1/2CK); a delay element (13) delaying the 1/2 clock signal (1/2CK) output from the address counter (12) by one clock on the basis of the main clock signal (CK) to output it; a delay element (14) delaying the address signal (ADD) output from the address counter (12) by one clock on the basis of the main clock signal (CK) to output it; an 1/2 line memory (15) directly provided with the address signal (ADD) output from the address counter (12), and provided with the 1/2 clock signal (1/2CK) output from least significant bit (LSB) of the counter (12) as a read enable signal(RE1) and a write enable signal (WE1) to read/write image data of one horizontal line every one period of the main clock signal (CK); an 1/2 line memory (16) directly provided with the address signal (ADD) output from the delay element (13), and provided with the 1/2 clock signal (1/2CK) output from the delay element (14) as a read enable signal(RE2) and a write enable signal (WE2) to read/write image data of one horizontal line to alternate with the read/write operation of the 1/2 line memory (15) every one period of the main clock signal (CK).
