CCD Camera Signal-Processing IC Developed Extensive functionality, from the CCD drive timing generator to signal processing, integrated on a single chip
LC99001
Overview
Demand for miniature digital cameras is growing steadily due to their use in video conferencing and video telephone and due to their incorporation in mobile equipment, and even toys. Since images are indispensable resources for the development of the information society, digital imaging technology is becoming increasingly important. In particular, convenient, miniature, and low cost imaging interfaces are strongly desired for personal computer applications. To respond to these needs, Sanyo has developed and is now releasing the LC99001 signal-processing IC that integrates a color CCD camera CCD controller (LC99057) and a color digital signal processor (LC99067) on a single chip. By integrating all processing from the CCD drive timing generator to signal processing on a single chip, the LC99001 allows the mounting area to be reduced by 25%, and thus can contribute to miniaturization and lower production costs in end products. This product also supports use in personal computer applications by allowing intermittent reads from the CPU, and also provides an operating mode that operates in synchronization with an external timing signal. This device is controlled over an I2C bus, which allows the image quality (brightness and color) to be adjusted and various settings, such as noise suppression parameters and the operating mode, to be set freely. A compact CCD color camera system can be constructed from three chips: a CCD (either the 300,000pixel LC9998GL or the 250,000-pixel LC9997GL), the LC99001, and a CCD driver (the LC89901V).
Features
* Supports camera miniaturization and reduced costs by providing color digital signal processing on a single chip. * Provides a full complement of synchronization modes for easy connection with personal computers and other devices.
