2.12.1. How to Operate the Motion Detection Function

1). Set the Motion detection On (Bank2, 0x00/02/04/06[4]) - Set at low

2). Set the area for which to detect motion

: The screen is divided into 192 sections and each section is matched one to one.

- (BANK2, 0x20~0x37 - Channel 1, Bank2, 0x38~4F - Channel 2)

- (BANK2, 0x50~0x67 - Channel 3, Bank2, 0x68~7F - Channel 4)

3). Set the motion sensitivity 1 (Pixel Sensitivity: Set at BANK2, 0x10)

4). Set the motion sensitivity 2 (Temporal Sensitivity : Set at BANK2 0x01/03/05/07)

: When setting motion sensitivity, it is recommended to set the pixel sensitivity at “0x60” and

use the temporal sensitivity to send the sensitivity to situation.

5). Output of Motion Detection

: Motion information generated from each section is not to be generated separately through data

interface. In other words, the motion information needs to be confirmed in the register or It is not

included in the BT.656/1120(like) data.

: Motion information generated from each area can be displayed on the screen.

Display can be done through three approaches. This can be controlled using MOTION_PIC

(BANK2, 0x00/02/04/06[1:0]).
