Image Enhancement IC with LCD Backlight Control Function

■ OVERVIEW

The S2D13782 is an image enhancement IC that meets the quality requirements for in-vehicle ICs. It has color correction,

noise reduction, edge enhancement (sharpness) and other features. The S2D13782 also generates LCD panel control

signals and incorporates a backlight control function.

The Auto Movie Enhancement 2 Extended – Optimizer (AME2EX-OPT) can reduce the power consumption by 30% to

50% by adjusting the backlight of the LCD panel to an optimum luminous intensity. In conjunction with backlight control,

AME2EX-OPT can display colorful images with a high contrast by automatically adjusting input images to optimum

brightness, contrast, gamma curves and color saturation.

The color management function of the Auto Movie Enhancement 2 Extended - Color Converter Engine (AME2EX-CCE)

allows color hue and saturation to be freely adjusted in manual mode so that colors can be reproduced faithfully according to

the characteristics of the LCD panel connected.

The Noise Canceller and Color Expander (NCX) reduces block noise specific to digital images such as 1-Seg broadcasting,

and gradation noise that is likely to occur when input images have low gradations (16-bit, 18-bit).

Adaptive Sharpness (ADS) automatically identifies the text and image areas of input images and performs optimal edge

enhancement processing for each area.

For the CPU interface, either I2C or SPI (3-line/4-line) can be selected. For the image I/O interface, the 16/18/24-bit RGB

interface, 16-bit YUV interface or 8-bit YUV interface (ITU-R BT.656) can be selected. Moreover, to support LCDs that

require special horizontal/vertical synchronous signals, the S2D13782 incorporates a programmable timing controller that

generates timing signals for up to 10 lines.

The S2D13782 allows the drive capability of the output terminals for the LCD panel to be selected, the quality of output

signal waveforms can be optimized. It also incorporates a Spread Spectrum Clock Generator (SSCG), which greatly

contributes to reducing the amount of electromagnetic interference (EMI) radiated by the display system.
