●Development Scheme
This technical note is aimed at trying the connectivity in the hardware between customer’s system and our AIE Adaptive
Image Enhancer series.
We prepare various data and tools for every development STEP as follows other than this technical note, please
contact the sales staff in your duty also including the support system.
(1) Demonstration STEP
(You can try the standard image processing functions by the standard Demonstration kit at once.)
You can confirm on TV screen what carried out AIE processing of a camera image and the DVD video image.
・Standard Demonstration board kit
◎Demonstration board(TV-IN→BU1573KV→TV-OUT board)
◎Demonstration board operation manual
◎Demonstration software
If the software for the trial board is installed in your Windows PC(Windows 2000/XP), more detailed setting
is possible.
◎USB cable
(2) Confirmation STEP
(We will respond to customer’s camera module.)
・Specifications
We will provide specifications for AIE Adaptive Image Enhancer according to customer’s requirements.
・Function explanation
We will deliver you the function explanation describing detailed functions, register settings, external
interfaces, timing, and so forth of AIE Adaptive Image Enhancer according to your requests.
・Application note
We will deliver you the detailed explanation data on application development of AIE Adaptive Image
Enhancer according to your requests.
(3) System check STEP
(You can check the application operation as a system by the kit of system check tools and your camera
module.)
You can check the interface with your camera module and the application operation on the system check board using
the tools for user’s only.
・System check tools kit
◎Board for system evaluation
◎Manual for system evaluation
◎Macro command file for reference
*You can check the detailed functions of the application operation by your PC using the macro command file.
(4) Integrated check STEP with user’s system
(You can check the application operation as a system on your system check board using the integrated
check software.)
You can check the application operation on the sample LSI-equipped system check board by your camera
module using the integrated check software.
・On line Support；We will answer your questions about the software development.
●Cautions on use
(1) Absolute Maximum Ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break
down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any special mode
exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety measures
including the use of fuses, etc.
(2) Operating conditions
These conditions represent a range within which characteristics can be provided approximately as expected. The electrical
characteristics are guaranteed under the conditions of each parameter.
(3) Reverse connection of power supply connector
The reverse connection of power supply connector can break down ICs. Take protective measures against the breakdown due
to the reverse connection, such as mounting an external diode between the power supply and the IC’s power supply terminal.
(4) Power supply line
Design PCB pattern to provide low impedance for the wiring between the power supply and the GND lines.
In this regard, for the digital block power supply and the analog block power supply, even though these power supplies has the
same level of potential, separate the power supply pattern for the digital block from that for the analog block, thus suppressing
the diffraction of digital noises to the analog block power supply resulting from impedance common to the wiring patterns. For
the GND line, give consideration to design the patterns in a similar manner.
Furthermore, for all power supply terminals to ICs, mount a capacitor between the power supply and the GND terminal. At the
same time, in order to use an electrolytic capacitor, thoroughly check to be sure the characteristics of the capacitor to be used
present no problem including the occurrence of capacity dropout at a low temperature, thus determining the constant.
