CXD4129GG, Security Cameras System ICs that CXD4130GG Support 960H CCD Image Sensors ∗ "ARM" is a trademark of ARM Limited. Sony has now released two new system ICs in the "Effio" Series for high-resolution, high-sensitivity, and excellent color reproduction security cameras: the "Effio-P" for high-end products and the "Effio-S" for midrange products. In addition to improving the basic picture quality performance, these new devices also integrate both memory and a microcontroller in the same package. In conjunction with the previously released entry-level model "Effio-E"∗1, Sony is now providing a full lineup of "Effio" Series products as a security camera platform. ∗1: See the New Products section in CX-NEWS, Volume 61. "Effio-P" CXD4129GG "Effio-S" CXD4130GG ■ Horizontal resolution of over 650 TV lines ■ Built-in high-performance WDR and ATR-EX functions ■ Digital image stabilizer (DIS) function ■ Built-in memory and microcontroller * "Effio" is a trademark of Sony Corporation. The "Effio" is a signal processor chip from Sony employing processing modes that deliver high resolution, high S/N ratio and excellent color reproduction. Horizontal Resolution of Over 650 TV Lines The "Effio-P" (CXD4129GG) and "Effio-S" (CXD4130GG) devices, when combined with an analog front end (AFE: CXD4813GG or CXD4816GG) IC, form a camera system that supports 760H and 960H CCD image sensors. (See figure 1.) These new devices, especially when combined with 960H CCD image sensor, can achieve high horizontal resolutions of over 650 TV lines and can provide highly detailed images. (See table 1.) Built-in High-Performance WDR and ATR-EX Functions The WDR (wide dynamic range) function included in the "Effio-P" (CXD4129GG) is based on Sony's proven dual shutter method and includes a refined version of the synthesis and compression algorithms for improved performance. As a result, the exposure correction function for high contrast scenes has been improved further and cameras using this device can acquire natural images with fewer blown out highlights and blocked up shadows. (See photograph 1.) Furthermore, these devices include the ATR-EX function, which feat u res improved calculation precision over that of the ATR (adaptive tone reproduction) function included in the "Effio-E" (CXD4127GG). These improvements make imaging with fewer blown out highlights and blocked up shadows possible, even in exposure modes that use the single shutter method. Built-in Memory and Microcontroller The "Effio-P" (CXD4129GG) and "Effio-S" (CXD4130GG) include both flash memory for program storage and the microcontroller that runs the user applications, which were previously provided as separate chips. This flash memory can also be used to hold camera adjustment values instead of the EEPROM that had been used previously. Sony also provides sample microcontroller software for camera developers as a board support package. These devices also include the DRAM required for implementing electronic zoom, slow shutter, noise reduction, and other functions. Not only do these contribute to reducing parts counts and reducing circuit board area for lower development costs, but they can also reduce our customers' camera development periods as well. Digital Image Stabilizer (DIS) Function These devices now include a digital image stabilizer (DIS) function, which is highly desired in midrange to high-end models. This allows the image shaking that can easily occur when cameras are mounted outdoors or in higher locations to be suppressed electronically. It is also effective at suppressing image shaking that occurs when zooming in on the subject. I t t o o k a l o t o f t h o u g h t a n d e ff o r t , including revising the control methods, to make it possible to implement the camera functions using only internal memory, but we worked together as a team. We think that by filling out the "Effio" line we have made it easier for camera manufacturers to structure their camera lineups. We strongly recommend that you look into the "Effio-P" and "Effio-S" products.
