When you press the shutter button to a recording, the sensor of a DSLR camera is exposed to light, and the image sensor data acquisition. This data can be processed on the device and written on the memory card.
To help speed up the process buffer, the digital SLR camera (consisting of RAM or RAM), which temporarily holds data information from the camera is recording on the memory card. Intermedia camera accelerates time between recordings and enables continuous shooting mode (burst). This mode refers to the ability of the camera a plurality of images immediately after the other. The number of images that can be recorded at the same time depends on the size of the buffer in the camera memory.
Most modern DSLRs contain significant reserves that keeps you shooting while the data is processed in the background. DSLRs not original buffer contain not, and had for each plan to draw back before addressing wait!
The buffer device may be stored before or after the image processing.
- Directly placed in the buffer before processing the image buffer. Raw data from the sensor. The data is processed and written to the memory card in conjunction with other tasks. For cameras with this type of buffer Continuous shooting can not be increased by reducing the size.
- After processing image buffer. Processed images and before he placed in the buffer into its final form. For this reason, the number of photographs can be taken in burst mode by the image file size be increased.
Some DSLRs now use buffer "smart". This method combines the elements before and after buffering. Untreated files stored in the buffer of the device to allow for "frames per second" (fps) higher rate. Then treated in its final form, and back into the buffer. Files can be written in the memory card while the images are processed, thereby providing a bottleneck.
