GENERAL DESCRIPTION
The KS7314 offers enlarged image through the zoom effect attained by horizontal and vertical interpolation of luminance and chrominance signal input supplied from CCD digital signal processor (KS7306) implemented by employing a 2nd generation electronic zoom IC which electronically enlarges the image picked up by the CCD of a camcorder. Besides, it provides a function of correcting wobble of camera holding hands, being coupled with the worked of a gyro-sensor, and a special effect function namely the mosaic mirror in addition.
FEATURES
- 256 discrete zoom steps.
- Field memoriless zoom operation.
- Vertical image expansion and vertical interpolation by the control of a built-in 2H delay line.
- Zoom operation dependent upon Y, R-Y, B-Y signal input (Source Format ® 4:1:1).
- Variable zoom ratio technology applicable to horizontal and vertical directions (Styling Effect):
- Correction of wobbling hand by the sub-pixels in vertical direction.
- Correction of wobbling hand in horizontal direction.
- Provision of special effects available:
• Horizontal mirror technology.
• Variable 16 mode mosaic block size technology.
(Mosaic function available in EIS mode)
- Linear interpolation algorithm applied to both luminance and chroma signals in horizontal and vertical directions.
- Applicable to wide TV screen with 630,000 pixels.
- Applicable to world-wide models, of different systems like NTSC/PAL, HI8/NORMAL, and DVC.
- Electronic zoom ratio:
Expansion available upto four times (4´) maximum, and the more in horizontal zooming.
- Operable normally at 3.3 / 5.0 voltages.
