We have commercialized the "IU233N2-Z (color)" and "IU233N5-Z (monochrome)" lens modules targeting the wearable and small mobile device market. These are the world's smallest*1 1M-pixel lens modules.
The world's smallest 1M-pixel lens module (2.6 mm*2 (W) × 3.3 mm (D) × 2.32 mm (H)) was realized by newly developing a super small 1M-pixel image sensor with a chip size of 2 mm × 2 mm and a super-small low-profile lens with a head size of 2.6 mm × 2.6 mm. This lens module is also equipped with a low power consumption mode that reduces power consumption by approximately 10 % to 60 % compared to existing image sensors with an equivalent number of pixels for mobile applications. This makes it the ideal lens module for super-small and lightweight mobile devices.
The IU233N2-Z and IU233N5-Z will help to further reduce the size and weight of mobile devices such as head-mounted displays and smart watches, and to develop new markets such as IoT and drones.

*2. Not including the flexible printed circuit board.
The IU233N2-Z and IU233N5-Z realize the world's smallest size by combining the world's smallest*3 laminated-type diagonal 1.72 mm (Type 1/10.49) approx. 1.06M-effective pixel CMOS image sensor, a lens with a head size of 2.6 mm (W) × 2.6 mm (D) × 1.45 mm (H), and lens-mount technology cultivated though the development of lens modules for mobile applications.
To secure compactness in consideration of assembly into products, the number of connector pins has been reduced to 20, and the width of the flexible printed circuit board and connector has been narrowed to 3.3 mm.
The head part alone weighs just 0.02 g and the weight including the flexible printed circuit board is 0.1 g or less, making this module ideal for small and lightweight mobile products.

The IU233N2-Z and IU233N5-Z have a low power consumption mode that realizes remarkably low power consumption, especially when using a low frame rate.
Power consumption during all-pixel output (1M-pixel) is approximately 55 mW at 60 frame/s, approximately 22 mW at 15 frame/s, and approximately 8 mW at 3 frame/s.
The IU233N2-Z uses an internal parallel column A/D converter, and can operate at the high frame rates of 120 frame/s in scan mode (Mode 1) or scan mode (Mode 2), or 240 frame/s in scan mode (Mode 3).
Likewise, the IU233N5-Z also uses an internal parallel column A/D converter, and can operate at the high frame rates of 240 frame/s in scan mode (Mode 1), or 120 frame/s in scan mode (Mode 2).
Both the IU233N2-Z and IU233N5-Z achieve approximately 4 times higher sensitivity in scan mode (Mode 1) by binning the adjacent 4 pixels (Table 2).

One of our specialties is super miniaturization technology, which we utilized to develop the world's smallest lens module. While it is a challenge to simultaneously realize both a small size and good picture quality performance in a lens module, we were able to achieve this by developing a new image sensor and optimizing the lens design. We hope that many people will be able to try this super-small lens module in wearable devices and also various other small mobile devices. Please consider using the IU233N2-Z/IU233N5-Z lens module.
Preparations are underway for purchase of this product via the Chip One Stop, Inc. website from late January 2017.
