Overview
General Description The IP00C720 is a low-cost device for real-time image reduction and expansion up to W-XGA resolution.
The IP00C720 supports input image sizes from NTSC to SXGA and output resolution up to W-XGA (1366 x 768 pixels) at 76 Mpixels/sec.
It makes use of an improved pixel interpolation algorithm based on 4 pixels in the horizontal direction and 2 pixels in the vertical direction.
It is ideally suited for low-cost applications because it can operate from one single SDRAM memory chip.
The input and output ports are completed independent to allow image scaling even if the input and output images have different frame rates.
