HD49815TF Datasheet, PDF (2/25 Pages) Hitachi Semiconductor – Digital Camera Signal Processor

HD49815TF
Features (cont)
• Since the HD49815TF can be made compatible with the former product, HD49811TFA, through
software, a shorter development term is enabled.
• Since software controls AWB, AE, and AF, any protocol can be prepared according to the camera
shooting conditions.
• Programmable TG enables use of any CCD device.
