Diagonal 7.20 mm (Type 1/2.5) Approx. 8.51M-Effective Pixel Color CMOS Image Sensor
16:9 Aspect Ratio CMOS Image Sensor Capable of 4K (3840 × 2160) Output for Industrial Applications
Sony has commercialized the "IMX274LQC" Type 1/2.5 (16:9) back-illuminated CMOS image sensor with approximately 8.51M effective pixels for the expanding 4K market.
The IMX274LQC is capable of 4K (3840 × 2160) output at 60 frames/s in ADC 10-bit mode. In addition, the DOL (Digital Overlap)-type HDR (High Dynamic Range) function is supported at 30 frames/s, realizing 4K video imaging with a wide dynamic range. The IMX274LQC has lower power consumption and is smaller than the existing 4K support CMOS image sensor (IMX172LQT), and the interface supports Sub-LVDS and MIPI CSI-2, enabling use in security camera and industrial applications.

* 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.
* STARVIS is a trademark of Sony Corporation. The STARVIS is back-illuminated pixel technology used in CMOS image sensors for surveillance camera applications. It features a sensitivity of 2000 mV or more per 1 µm2 (color product, when imaging with a 706 cd/m2 light source, F5.6 in 1 s accumulation equivalent), and realizes high picture quality in the visible-light and near infrared light regions.
High-speed video imaging function
The IMX274LQC realizes 4K (3840 × 2160) all-pixel scan at 30 frames/s in ADC 12-bit mode, and at the high frame rate output of 60 frames/s in ADC 10-bit mode, making it the ideal CMOS image sensor for expanding 4K market applications. The IMX274LQC also realizes Full HD (1920 × 1080) output at 60 frames/s in ADC 12-bit mode (mode 1) and 120 frames/s in ADC 10-bit mode (mode 2), enabling high-speed video imaging. In addition, various other readout methods are also supported, and diverse drive modes can be selected (Table-3).
Use of a lower frame rate makes it possible to reduce power consumption.
Versatile interface
The IMX274LQC is equipped with two types of output interface (Sub-LVDS, MIPI CSI-2) to meet diverse needs. Both interfaces are capable of 4K 60 frames/s (ADC 10-bit) output, so the interface can be selected in accordance with the DSP and system used (Table-1).
DOL-HDR function
The IMX274LQC is Sony's first CMOS image sensor to support a DOL-type HDR function for a 4K angle of view. This makes it possible to shoot 4K video with an expanded dynamic range. The modes that support the DOL function are 4K (3840 × 2160) ADC 10-bit 30 frames/s and Full HD (1920 × 1080) ADC 10-bit 60 frames/s (Table-3).
Compact device size
The IMX274LQC realizes a compact package size of 10.70 mm (H) × 8.50 mm (V) × 1.62 mm (t). This reduced camera size expands the range of potential security camera and industrial applications.
