\u25cfOmniVision's high-performance OV16880 is a 1\/3.06-inch 16-megapixel image sensor based on OmniVision's PureCel\u00ae Plus-s stacked chip technology. The sensor leverages advanced 1-micron pixels to bring advanced features such as ultra-high-resolution image and video capture and phase detection autofocus (PDAF) to slim smartphones and tablets. \u25cfOmniVision's PureCel\u00ae Plus-s sensor utilizes buried color filter array (BCFA) and deep trench isolation (DTI) technology to greatly reduce pixel crosstalk and improve signal-to-noise ratio to produce superior images and videos. In addition, the technology allows for larger chief ray angle (CRA) lenses without compromising image quality, enabling slimmer module designs. \u25cfThe OV16880 PureCel\u00ae Plus-S image sensor is capable of capturing 16-megapixel (4672 x 3504 pixels) images at 30 frames per second (fps), enabling full-resolution burst shooting and zero shutter lag. In addition, the sensor is capable of capturing 4K video at 30 fps, 1080p video at 90 fps, and 720p video at 120 fps. \u25cfThe sensor can be mounted in an 8.5 x 8.5 mm module with a z-height of less than 5 mm. \u25cfProduct Features: \u25a0Automatic black level calibration \u25a0Programmable control of frame rate, mirroring and flipping, cropping and windowing \u25a0Support dynamic DPC cancellation \u25a0Support output format: 10-bit RAW RGB \u25a0Support horizontal and vertical subsampling \u25a0Support typical image sizes: 4672×3504, 4672×2628, 2336×1752, 1920×1080, 1280×720 \u25a0Support 2×2 binning \u25a0Standard serial SCCB interface \u25a0Up to 4-channel MIPI TX interface with speed up to 1.5 Gbps\/channel \u25a0Programmable I\/O drive capability \u25a0Up to 1\/2\/4-channel LVDS interface with speed up to 1.5 Gbps\/channel \u25a0Embedded 13kbit (1664 bytes) one-time programmable (OTP) memory for customer use \u25a0Interlaced row HDR output \u25a0Support high-speed AF \u25a0Support PDAF \u25a0Three on-chip phase-locked loops \u25a0Programmable I\/O drive capability \u25a0Built-in temperature sensor OV16880 camera image sensor FAQ\uff1a Q1: What type of image sensor is OV16880? A1: OV16880 is a high-performance 16-megapixel CMOS image sensor that uses stacked chip technology to provide 4672×3504 resolution images at 30fps. It is designed for high-resolution digital still cameras (DSCs), HD camcorders, and mobile phones to provide high-quality imaging solutions. Q2: What are the main features of the OV16880 image sensor? A2: The main features of the OV16880 image sensor include: High resolution: 16 million pixels, providing delicate image details. High performance: Capable of taking full-resolution photos at 30fps, with support for burst shooting and zero shutter lag. Flexible configuration: User-programmable image resolution, frame rate, and image quality parameters. Advanced technology: Adopts PureCel Plus-S stacked die technology, with buried color filter array (BCFA) and deep trench isolation (DTI) technology to reduce pixel crosstalk and improve signal-to-noise ratio. Wide application: Suitable for a variety of devices such as smartphones, tablets, digital cameras, etc. Q3: What common problems may occur with the OV16880 image sensor? A3: The OV16880 image sensor may encounter the following problems during use: Overtemperature: Long-term operation will cause the temperature to rise, which may cause the "hot pixel" phenomenon, that is, the increase in noise caused by chip overheating. Voltage problem: Low or unstable analog voltage may cause the image sensor to malfunction, such as color cast, stripes, or require stronger light to sense the image. Mechanical damage: Mechanical shock or vibration may cause damage to the internal structure. Electromagnetic interference: Strong electromagnetic fields or electromagnetic wave interference may affect the normal operation of the sensor. Circuit failure: Data line short circuit, open circuit or wrong connection may cause image anomalies, such as color cast, water ripples, etc. Q4: How to solve the "hot pixel" problem of OV16880 image sensor? A4: The "hot pixel" problem is usually caused by chip overheating. The solution includes: Ensure that the device is well cooled and avoid long-term continuous operation. Perform noise suppression at the software level, such as using digital filtering technology. If the problem is serious, you may need to consider replacing the sensor or contacting the manufacturer for repair. Q5: What should I do if I encounter image color cast or stripe problems? A5: When you encounter image color cast or stripe problems, you can try the following solutions: Check whether the analog voltage is stable and meets the specifications. Check whether there are strong electromagnetic interference sources around the sensor and try to stay away from it. Check whether the data cable is connected correctly and there is no short circuit or open circuit. Try to recalibrate the sensor or update the firmware. If the problem persists, it is recommended to contact a professional repairman or the manufacturer for further inspection and repair. Q6: How to prevent damage to the OV16880 image sensor? A6: To prevent damage to the OV16880 image sensor, you can take the following measures: Avoid long-term continuous operation and pay attention to heat dissipation. Use a stable power supply and voltage to avoid voltage fluctuations. Handle the device with care to avoid mechanical shock and vibration. Keep away from strong electromagnetic interference sources. Regularly check and maintain the device to ensure that all components are connected properly.<\/p>","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_eb_attr":"","footnotes":""},"categories":[613],"tags":[662],"class_list":["post-13221","post","type-post","status-publish","format-standard","hentry","category-16mp-4k-camera-sensor","tag-ov16880"],"_links":{"self":[{"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/posts\/13221","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/comments?post=13221"}],"version-history":[{"count":0,"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/posts\/13221\/revisions"}],"wp:attachment":[{"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/media?parent=13221"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/categories?post=13221"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/tags?post=13221"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
