A digital camera captures images from the real world using sensors for capturing, sampling and quantization for processing the image.

Explanation:

Digital camera's contains arrays of electronic photo detectors which are also called photo sensors used to convert light photons to electric, these absorbed photons make electron hole pairs in depletion region to capture images focused by lens.

Capturing an image from a camera is a physical process using the sunlight as a source of energy. A sensor array is used for the acquisition of the image. So when the sunlight falls upon the object, then the amount of light reflected by that object is sensed by the sensors, and a continuous voltage signal is generated by the amount of sensed data.

In order to create a digital image , we need to convert this data into a digital form. This involves sampling and quantization which results in an two dimensional array or matrix of numbers which are nothing but a digital image.

Answer:

subtotal function

Explanation:

The Microsoft Excel SUBTOTAL returns the subtotal of the numbers in the columns in a list or database, and it can be applied horizontally as well as vertically. And the SUBTOTAL function happens to be the built-in function in Excel which is categorized as the Math function or the Trigger function. And like a worksheet function, it can be inserted as a part of the formula inside a cell of a worksheet. Select the columns in a row, or rows in a column, and move to the Data tab in the ribbon. From there,  select the SUBTOTAL, and the function you would like to use, and press ok. And this means here the correct option is the subtotal function.
