Additionally, they made the camera driver an open source and provided an SPI camera solution.īack then, it was difficult for MCUs, e.g., Arduino, to handle image sensors with equal to or resolutions higher than 2MP. OV2640 on Arduino dates back to 2012, when a dedicated team presented the sensor into the communication protocol (Arduino platform). Several factors contribute to the popularity of OV2640. As such, you can easily process and store it in the internal RAM of a microcontroller. So, a higher compression ratio or lower image resolution results in a smaller JPEG image size output. Contrarily, a JPEG format with a similar image occupies 150KB space (approximately ×25 compression ratio). Next, its hardware JPEG encoder feature lessens memory footprint usage and divests the processing power from the MCUs.Ī YUV format image/1600×1200 RGB565 often occupies a RAM space of 3.66MB.Then, it is user-friendly for low-end RISC and ARM microcontrollers such as ESP32 and STM32.Furthermore, it has a Digital Video Port (DVP) sensor interface with an associated pixel clock, vertical/synchronization signal, and 8-bit data.The outcome is a nicely-represented image. The SOC sensor comprises an on-chip ISP that performs auto-white balance and auto-exposure in small sensor packages.ĭespite not being fancy based on its image quality, resolution, and sensor format, OV2640 still stands out as an excellent image sensor. Its maximum image transfer rate is, , and 1600 ×.The package dimension is 5725 × 6285µm, whereas its image area is 3590 × 2684µm.Besides, its output format is Raw/RGB/YUV RGB data, and its resolution is UXGA SVGA and below.The image format is type 1/4” with a sensitivity of 0.6V/Lux-sec and a dark current of 15mV/s at 60☌.To learn more about how and for what purposes Amazon uses personal information (such as Amazon Store order history), please visit our Privacy Notice.An image displaying the Y, U, and V components (top to bottom) You can change your choices at any time by visiting Cookie Preferences, as described in the Cookie Notice.
