GC4653 camera image sensor FAQ

1. What type of image sensor is GC4653?

GC4653 is a high-quality 4Mega CMOS image sensor suitable for security camera products, digital camera products and mobile phone camera applications. It integrates a high-performance pixel array, ADC (analog-to-digital converter) and image signal processor, with the characteristics of full integration, which is easy to design and implement.

2. What are the pixel size and resolution of GC4653?

The pixel size of GC4653 is 2.0μm x 2.0μm (BSI), with a pixel array of 2560Hx1440V, that is, a resolution of 4MP (million pixels). This high resolution can provide clear image quality.

3. What is the maximum frame rate of GC4653?

The maximum frame rate of GC4653 is 30fps (frames per second) at full size. However, according to specific needs, the frame rate can be adjusted by modifying the settings, such as reducing to 20fps to increase exposure time or reduce transmission bandwidth.

4. What power requirements does GC4653 support?

The power requirements of GC4653 include three main parts:

AVDD28: analog power supply, ranging from 2.7~2.9V (typical value is 2.8V).

DVDD: Digital circuit power supply, ranging from 1.15~1.25V (typical value is 1.2V).

VDDIO: I/O power supply, ranging from 1.7~1.9V (typical value is 1.8V).

5. What is the package type of GC4653?

The package type of GC4653 is 41PIN-CSP (Chip Scale Package), which is a chip-scale package. This package type helps to reduce the overall size and improve the integration of the product.

6. In what fields is GC4653 used?

GC4653 is mainly used in security equipment, such as security cameras, car cameras, etc. At the same time, due to its high performance and comprehensive integration capabilities, it is also widely used in digital cameras and mobile phone cameras.

7. How to adjust the output frame rate of GC4653?

Adjusting the output frame rate of GC4653 is usually achieved by modifying VTS (frame length). The exposure time of a frame image is equal to the frame length multiplied by a line time. Increasing the frame length will increase the exposure time of a single frame image, thereby reducing the number of frames per unit time, that is, reducing the frame rate. The specific adjustment method needs to refer to the sensor's data sheet and setting instructions.

8. How does GC4653 perform in low-light environments?

The performance of GC4653 in low-light environments is affected by its sensitivity and noise characteristics. Higher sensitivity and lower noise levels help to obtain better image quality in low light. In addition, by adjusting parameters such as exposure time and gain, the image effect in low light can be further optimized.

9. What are the color response characteristics of GC4653?

As a CMOS image sensor, the color response characteristics of GC4653 are affected by photodiodes and color filters. Silicon image sensors are generally more sensitive to red and green, but less sensitive to blue. Therefore, the color correction and balance of the sensor need to be considered during the design and application process to ensure accurate color reproduction.

10. What is the operating temperature range of GC4653?

The operating temperature range of GC4653 is -20℃ to 80℃. Within this temperature range, the sensor can maintain stable performance and reliable image output. However, when used in extreme high or low temperature environments, additional heat dissipation or insulation measures may be required to ensure the normal operation of the sensor.
