The image processor, supplied with an image analysis system, is a circuit board or board set specialized for handling large image files and designed to interface to cameras. The image processor, under the control of the host computer, is responsible for image acquisition, transformation, and display. Image processors use large memory buffers to store images and specialized hardware designed to increase the speed of certain operations. A frame buffer is a bank of random access memory located within the imaging system. Large amounts of fast image memory are incorporated in standard imaging systems. In a modular image processor, the imaging components can transfer data very rapidly by communicating with each other using a dedicated and fast data path called the imaging bus. Data can be transferred more quickly in this manner than via the host-computer bus. The bandwidth of the imaging bus determines the data manipulation limit of the imaging system. At the time of writing, most manufacturers used a 15- to 20-MHz imaging bus, although more expensive systems use bus bandwidths of 40 MHz or more.

The cameras used for our study are Canon electro optical system (EOS) 70D (Kissiyar et al., 2008) which is having 20.2 megapixels with advanced photosystem type-C (APS-C) CMOS-sensor and built in Wi-Fi and have digital imaging integrated circuit (DIGIC) 5+ image processor with ISO-range of 100–12800 (H: 25600) with electronic shutter. CMOS-sensor stands for complementary metal oxide semiconductor that converts the light into electrical signals. It allows shooting in a wide variety of lighting conditions. The touchscreen is 3-inches with 19-point cross type auto focus and 7.0 fps continuous burst shooting. Canon’s EOS 70D captures a massive 5472 × 3648-pixel resolution, which is good enough for even the largest enlargements and offers the best quality for significant cropping, while preserving the essence and detail of the scene. 14-bit signal processing ensures excellent tonal gradation and a wide (the International Organization for Standardization) range of 100–12800 (H: 25600) ensures excellent image capture even in dim lighting situations. Canon’s EOS 70D uses the DIGIC 5+ Image Processor to enhance the camera’s image sensor for faster data processing, improved noise reduction and even real-time compensation for chromatic aberration.
Chromium and cadmium removal from wastewater using duckweed - Lemna gibba L. and ultrastructural deformation due to metal toxicity

Scanning electron microscopic (SEM) study provides very fine details at high resolution of biological specimen. SEM analysis was done in central instrumentation laboratory at Punjab University, Chandigarh, India. Digital scanning electron microscope - JSM 6100 (JEOL) is equipped with a digital image processor where biological specimen were stored in 0.1 M buffer at 4 °C after primary fixation were received for studies. Further treatment was undertaken by the technical personnel appointed by the Centre.

A multiplier is the core component of processors such as a digital signal processor, image processor and many more which are responsible for the synthesis of the videos and images for digital content in portable gadgets requiring a considerable amount of time and power. As a result, low-power and high-performance processors are required which in turn can be achieved by power and speed efficient multiplier unit as discussed in Meher & Stouraitis, (2017).
