Sony Ericsson XCI-V3 Partial scan mode

Partial scan mode

This mode can be set using the HIGH RATE SCAN screen in the GUI application for camera settings.

In this mode, the desired rectangle area is read out, and the redundant image area is transmitted at high speed to raise the frame rate. The read out area can be set separately as an effective image area vertically and horizontally. For the XCI-SX1, the effective image area is vertically divided into 32 areas and horizontally divided into 10 areas. You can select a specific portion among those from 1 block to 32 blocks vertically in

units of one block separately or succesively, and 3 blocks to 10 blocks horizontally in minimum units of successive 3 blocks. For the XCI-V3, the effective area is vertically divided into 16 areas and horizontally divided into 10 areas. You can select a specific portion among those from 1 block to 16 blocks vertically. Partial scan can be individually set in a horizontal or vertical direction.

The tables below show approximate frame rate values when the partial scan mode is used.
