* Diagonal 9.33 mm (Type 1/1.7) Approx. 12.40M-Effective Pixel High-Speed, High-Sensitivity Back-Illuminated CMOS Image Sensor for Consumer Digital Still Cameras and Camcorders


As the opportunities for shooting stills and video increase, users are demanding more from their compact digital still cameras and camcorders in terms of high-picture quality and high performance. Sony has responded to this demand by commercializing the IMX144CQJ, a Type 1/1.7 approx. 12.40M-effective pixel back-illuminated CMOS image sensor ideal for high quality compact digital still cameras and camcorders.

. .

■ Diagonal 9.33 mm (Type 1/1.7) approx. 12.40M-effective pixels (4072H x 3046V)
■ Pixel size: 1.85 Ám unit pixel
■ Supports 12.40M-pixel imaging at approx. 35 frame/s
■ Back-illuminated CMOS image sensor featuring high sensitivity, high dynamic range and low noise
■ Provides 4K video mode (4096H x 2160V, 60 frame/s)

Exmor Logo

* "Exmor R" is a trademark of Sony Corporation.
The "Exmor R" is a Sony's CMOS image sensor with significantly enhanced imaging characteristics including sensitivity and low noise by changing fundamental structure of "Exmor" pixel adopted column-parallel A/D converter to back-illuminated type.

* Vast Improvement in Picture Quality
Compared to the current products, a Type 1/2.3 back-illuminated image sensor, the IMX144CQJ is a Type 1/1.7 back-illuminated image sensor that provides higher sensitivity, higher dynamic range and lower noise.
Larger pixel size for improved sensor characteristics and full use of Sony's unique fine pixel processing technology mean that the new image sensor has 1.3 times the sensitivity and 1.9 times the saturation signal level of the current Sony product, IMX078CQK (1.55 Ám unit pixel, Type 1/2.3, approx. 12.40M-effective pixels, see the New Products section in CX-NEWS, Volume 63). (See table 2.) Dark signal characteristics equivalent to the current Sony products ensure high picture quality from dark to bright areas. (See photograph 1.)
This image sensor possesses characteristics ideal for high-quality compact digital still cameras and camcorders where high picture quality is essential.
* Greater Optical Design Freedom
Larger pixel size combined with better light collecting characteristics have vastly increased incident light angle characteristics (see figure 1) and yielded more favorable f-number dependence over the current Type 1/2.3 back-illuminated image sensors. Thanks to these improvements, the new image sensor offers greater optical design freedom and can cope with brighter lenses and high power zoom lenses.
* 4K and Many Other Shooting Modes
Sony's unique high-speed scanning technology has allowed us to build a variety of drive modes. (See table 3.) The Type 1/1.9, approx. 9.03M-pixel (approx. 17:9) sensor enables high-definition and high-speed video recording of 4K 60 frame/s makes this consumer image sensor capable of the nextgeneration 4K format. Also, the image sensor comes not only with full HD at 60 frame/s (mode 1) but is capable of slow-motion shooting with HD at 240 frame/s (mode 4) and has plenty of other video functions.
* High Speed and Low Power Consumption
While the image sensor ensures high picture quality and high speed, the structure of the column-parallel A/D conversion circuit was reconfigured to reduce power consumption by about 34% compared to the current Sony products. (Mode 1: full HD 60 frame/s mode, see table 2.)
In addition to increasing the number of images that can be shot, these achievements have added value by greater versatility and low-power design.
•••• Mr. Inoue and Mr. Yagi••••
In the general trend towards ever higher pixel counts and fine pixel processing, our goal behind the development of the IMX144CQJ was to also design in "excellent picture quality in a compact size." Large pixel size and taking cutting-edge back-illuminated and fine pixel processing technology to the next level have significantly improved picture quality. We strongly recommend that you look into Sony's high-speed and high-sensitivity imaging technologies for your next camera.
