IPC: G03G21/00
Filed: 2019-06-06
Abstract: To achieve both image formation with a uniform density across the entire area in a conveyance direction of a long recording material, and prevention of deterioration of a developing roller and a photoconductor drum.SOLUTION: A control unit calculates an image ratio for a recording material one by one based on image data (S2). When the length in a conveyance direction of the recording material is equal to or more than a predetermined length (YES in S3), and the image ratio is equal to or less than a predetermined value (YES in S4), the control unit sets a development contrast to a first potential difference (S5). On the other hand, when the image ratio is larger than the predetermined value (NO in S4), the control unit sets the development contrast to a second potential difference smaller than the first potential difference (S6). After that, an image forming operation is started. With these operations, an image with a low density is formed across the entire area in the conveyance direction of the recording material, and the image density does not fall below a density at which a user can determine a difference in density by visual inspection. Thus, image formation with a uniform density across the entire area in a conveyance direction of a long recording material, and prevention of deterioration of a developing roller and a photoconductor drum can be achieved.SELECTED DRAWING: Figure 4

Title: System, program and the like
Inventor: TAKAHASHI KEIZO
IPC: H04W28/06
Filed: 2019-06-28
Abstract: To suppress further power consumption in a system for controlling communication means by LPWA.SOLUTION: In a drive recorder 1, a camera 18 captures an image of a driver's seat and outputs a vide signal indicating this image. A controller 11 converts this video signal into video data, analyzes the video data to determine a danger of driving, generates determination result data indicating a determination result, and causes an LPWA communication device 13 to transmit the generated determination result data to a server 2. Since the determination result data is data indicating a comprehensive determination result obtained by analyzing the content of the video data and comparing motion and a position of each site of a driver with a predetermined pattern, a threshold value, etc., an information amount of the determination result data is smaller than an information amount of the video data. Therefore, power to be consumed when a drive recorder 1 transmits data to the server 2 is suppressed as compared with a case where the drive recorder 1 transmits the video data which is data before the video data has been processed.SELECTED DRAWING: Figure 4
