GC4663 is a high quality 4Mega CMOS image sensor for security camera products, digital camera products and mobile phone camera applications. Full integration with high performance makes GC4663 fit the design and reduce the implementation process. GC4663 includes a 2560Hx1440V pixel array, on-chip 12\/10-bit ADC and image signal processor. It provides raw12 and RAW10 data formats with mipi interface. It has a common two-wire serial interface for the host to control the operation of the entire sensor. In addition, it also has an HDR function with interleaved output mode, allowing users to combine a picture with 2 different exposure time frames to improve dynamic range and avoid tailing.

What is the resolution of the GC4663 image sensor? A: The GC4663 image sensor has a resolution of 4 megapixels (4MP) and a pixel array of 2560×1440, which is capable of capturing high-quality images. 2. What data formats does the GC4663 support? A: The GC4663 supports RAW12 and RAW10 data formats with MIPI interfaces, which provide high flexibility and data processing capabilities. 3. What are the power requirements of the GC4663? A: The power requirements of the GC4663 include: AVDD28: 2.7~2.9V (typical value is 2.8V) for analog voltage. DVDD: 1.15~1.25V (typical value is 1.2V) for digital voltage. IOVDD: 1.7~1.9V (typical value is 1.8V) for input and output voltage. 4. How to adjust the output frame rate of the GC4663? A: Adjusting the output frame rate of the GC4663 usually involves modifying the settings of the frame time (VTS) and line time (line_time). The specific steps include: Determine the target frame rate (such as dropping from 30fps to 20fps). Calculate the pclk value using the formula pclk = frame_length * line_length * fps. Calculate the new frame time (VTS) based on the pclk value and the known line time (line_time) or line length (line_length). Modify the VTS value in the sensor settings to achieve the target frame rate. 5. How does the GC4663 perform in high and low temperature environments? A: The GC4663 operates over a wide temperature range of -20\u00b0C to 80\u00b0C with stable performance. However, at extreme temperatures, the performance of the sensor may be affected to a certain extent, such as increased dark current and reduced sensitivity. 6. Does the GC4663 support HDR function? A: Yes, GC4663 supports HDR function with interleaved output mode, which allows users to combine two different exposure time frames into one picture to improve dynamic range and avoid tailing. 7. How to solve the noise problem of GC4663 image sensor? A: Noise problem can be caused by many factors, such as excessive temperature, underexposure or improper sensor gain setting. Solutions include: Lower sensor temperature, such as adding heat dissipation measures. Adjust exposure time and gain settings to optimize image quality. Use image post-processing techniques such as noise reduction algorithms to reduce noise. 8. What is the package form of GC4663? A: GC4663 adopts CSP (Chip Scale Package) package form, which helps to reduce sensor size and improve integration. 9. Does GC4663 support automatic gain control (AGC)? A: Although the specific information may vary depending on the product version, in general, high-performance CMOS image sensors such as GC4663 usually support automatic gain control function to automatically adjust gain under different lighting conditions to obtain the best image quality. 10. What are the main application areas of GC4663 image sensor? Answer: The main application areas of GC4663 image sensor include security cameras, digital cameras, mobile phone cameras, smart home systems, IoT cameras, car driving recorders, video phones and conference equipment, etc.<\/p>","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_eb_attr":"","footnotes":""},"categories":[618],"tags":[652],"class_list":["post-13156","post","type-post","status-publish","format-standard","hentry","category-4mp-2k-camera-sensor","tag-gc4663"],"_links":{"self":[{"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/posts\/13156","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=13156"}],"version-history":[{"count":0,"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/posts\/13156\/revisions"}],"wp:attachment":[{"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/media?parent=13156"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/categories?post=13156"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/dgzx.hk\/vi\/wp-json\/wp\/v2\/tags?post=13156"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
