ROHM's TV encoder LSI with built-in camera image correction AIE offers exceptional visibility
This makes it ideal for surveillance cameras, home security systems, automobile drive recorders and vehicle mounted cameras, where visibility is often poor due to changing ambient conditions, extreme backlighting, or darkness. The BU6520KV rapidly analyzes input images, divides the images into areas using unique algorithms, extracts the optimum brightness and color correction parameters for each area, and conducts real-time, high-speed image correction. The brightness of dark and bright areas are adjusted proportionally, resulting in visibility similar to the human eye. All required settings such as NTSC/PAL values, sampling frequency, and gamma values, can be stored in and read from an external EEPROM, enabling operation without a microcontroller– unlike conventional TV encoder ICs. Additional features include support for composite and CCIR601/656 component outputs, wireless LAN compatibility, and access of image correction data via external EEPROM, enabling replacement in existing systems without the need for hardware or software modification.
