Title: Imaging device
Inventor: MAEDA TAKEHISA
IPC: B41J2/44
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To form a dot stably by suppressing occurrence of longitudinal streaks on an image regardless of fluctuation in the distribution of quantity of light among respective LED elements. SOLUTION: An image is formed using a group of two adjacent LED elements in an LED array 12 as the minimum unit of image information (1 dot). Even if a dot is formed unstably using only one LED element 3, peak quantity of light can be increased by summing the quantity of light of the LED elements 3 forming a group continuously and enlarging the distribution of quantity of light in the main scanning direction. Consequently, occurrence of longitudinal streaks is suppressed and dots D are formed stably.

Title: Facsimile terminal
Inventor: YOSHIDA TOMOKI
IPC: H04N1/21
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To reduce compression processing time by applying efficient compression processing to data in matching with the size of a buffer in use storing compressed data. SOLUTION: A system control section 30 decides the number of lines to be compressed in the basis of the size of a compression data storage buffer 28 in use. For example, in the case that the number of compression lines is 4, the system control section 30 checks whether there is an idle area by 4 lines in the compression data storage buffer 28, and when there is no idle area, the control section 30 halts the processing until the buffer has an idle area by 4 lines, and when the compression data storage buffer 28 has the idle area, an image data compression section 26 compressed the data by 4 lines. Then the completion of the compression processing is checked and when not finished, compression processing is repeated every time the buffer becomes idle, and when the end of the compression processing is confirmed, the compression processing is completed.
