OV3640 CMOS Camera Module All Documents

I finally downloaded the firmware level application notes for Auto-Focusing   OV3640 CMOS camera module. And also I found some source codes for firmware level (Auto-focus). That means we now control VCM (Voice Coil Motor) in OV3640 module. In our module used the embedded auto-focus solution.

Compact Camera Module

Concept

CCM, acronym of Compact Camera Module, is always used in cell phone. So it has another name, cell phone camera module. The sensor type used in this kind of module is CMOS or CCD.

Types
(1) Differentiated by sensor :
A. CCD-Charge Couple Device
B. CMOS-Complementary Metal Oxide Semiconductor.

Compared with CCD , CMOS sensor have smaller size, lower consumption, better integration and lower Cost.

(2) Differentiated by manufacture technics :
A. CSP-Chip Scale Package

Some kinds of packaged sensor are used in CSP process. It is convenient to make module with packaged sensor. There are no obvious performance differences between CSP and COB type in low pixel module, such as VGA and 1.3 Mega pixel.

B. COB-Chip On Board
Unpackaged sensor separated from the wafer are directly used in COB process. The image performance or COB type is better than CSP because no additional glass is covered on the senor. And the module height is lower.

(3) Differentiated by lens :

AF (Auto Focus Lens) Working Concept

Using Voice Coil Motor (VCM) for lens movement.
VCM use the Lorentz force which is generated from the energized coils and the permanent magnets for moving the Lens.

Offering CCM for applications
•Cell phone, video phone
•PDA, PMP,MP4
•Vehicle-mounted camera-car reverse camera
•Toy
•Scope and security system
•Medical product
•DSC
•PC camera, laptop/notebook camera, webcam

Тэнгэр шиг бай

Хамаг бүгдээр чамайг

Харааж нулимж байвч тэнгэр шиг бай

Хамгийн сайн хүмүүс гэж

Хашгирч ерөөж байвч тэнгэр шиг бай

Тэвчээр барагдаж, нөхөд чинь орхивч

Тэнгэр шиг бай, мөнхөд амгалан

Тэргэнд суулгаж алтан титэм өмсгөвч

Тэнгэр шиг бай, юу ч болоогүй юм шиг

Хамгийн хайртай хүн чинь хаяж одсон ч

Хан тэнгэр нурчихаагүй цагт бүү зов

Гүтгэж доромжилж бахаа ганц хангавч

Гүн тэнгэр хэмхрээгүй цагт бүү ай

Өвчин зовлонд нэрвэгдэж тартагтаа тулавч

Өнө мөнхийн тэнгэр шиг бай, чи ялна

Өрөөл бусдад тоогдохоо байж мартагдавч

Өндөр тэнгэр дээр чинь цэлийж буйг бүү март

Яг л амьдрал чинь дуусаж, явах замгүй болсон ч

Яадгаан алдалгүй хүлээ, тэнгэр шиг бай

Яаруухан санаа мөхөсдөж, хулгай зэлгийд өртсөн ч

Ядмагхан амьтдыг бүү тоо, тэнгэр шиг бай

Олз омог чамд үүдээ хаасан ч тэнгэр шиг бай

Олон түмэн нүүрээ бууруулсанч тэнгэр шиг бай

Одод гялалзаж наран саран ээлжлэх цагт

Орчлон дээр аавын хүү шантрах ёсгүй

Project Load Failure

I meet some trouble for VS2005 Project load. I found some error fixing methods from some blog. 

Try out the following
1. For each user on the machine remove the %userprofile%\Local Settings\Application Data\Microsoft\CoreCon\1.0 Folder and all files under it.
2. For each user on the machine rename the %userprofile%\Application Data\Microsoft\Device Emulator\ folder to %userprofile%\Application Data\Microsoft\Device Emulator_B2\

3. Repair the Windows Mobile 5.0 SDKs
