And Debugging

Key words: SM8250, Spectra 480, ISP, Know-How

1.1 Introduction

The document describes how to dump frames for camera tuning and debugging.

1.2 Frequently Used Command Overview

<Camxsettings.xml> shows the details information of dump command, below listed frequently used command.

persist.vendor.camera.autoImageDump

1：enable dump

0：disable dump

persist.vendor.camera.autoImageDumpMask

ImageDumpType will limit dumps to only the specified nodes and ports

when autoImageDump is enabled.

No dumps = 0x0

All output ports for IFE = 0x1

All output ports for IPE = 0x2

All output ports for BPS = 0x4

All JPEG output ports for all JPEG nodes = 0x8

All output ports for FDHw = 0x10

All output ports for LRME = 0x20

All output ports for RANSAC = 0x40

All output ports for all ChiNodes = 0x80

All output ports for CVP = 0x100

All other nodes not explicitly listed above = 0x40000000

persist.vendor.camera.autoInputImageDumpMask

ImageDumpType Will limit dumps to only the specified nodes when

autoInputImageDump is enabled.

No dumps = 0x0

All input ports for IFE = 0x1

All input ports for IPE = 0x2
