请教ZR36060的寄存器配置
各位老师:
大家好! 上次我发的一个关于咨询OV7620和ZR36060的匹配接口的贴子,现在已经解决了,在此衷心感谢大侠孙江波和guo263的鼎力相助. 现在开发中又遇到这样一个问题,就是数据传回来后,将其转存为JPEG文件,格式都正确,但看到的图像却是五彩斑斓,根本看不出拍摄景物,我怀疑是JPEG的寄存器配置的问题,请教各位老师,我想进行静态图像采集,对存储容量要求不严格,以下寄存器应该如何配置: 1. 0x003(Codec Mode Register) 2. 0x005(Maximum Block Code Volume Register) 3. 0x009~0x00C (Target Net Code Volume Register) 4. 0x00D~0x010 (Target Data Code Volume Register) 5. 0x011~0x012 (Scale Factor Register) 6. 0x013~0x015 (Allocation Factor Register) 7. DRI段、DQT段和DHT段能否完全按照Datasheet上的推荐参数 8. APP段和COM段是否可以不要,也不用在寄存器的0x380~0x3FF中进行初始化. 有哪位老师能百忙之中抽空帮我一把，万分感激！ |
