ImageGrab and PyTesseract
ImageGrab is a Python module that helps to capture the contents of the screen. PyTesseract is an Optical Character Recognition(OCR) tool for Python. Together they can be used to read the contents of a section of the screen.
Pillow (a newer version of PIL)pip install Pillow
PyTesseractpip install pytesseract
Apart from this, a tesseract executable needs to be installed.
Implementation of code
The following functions were primarily used in the code –
pytesseract.image_to_string(image, lang=**language**) – Takes the image and searches for words of the language in their text.
cv2.cvtColor(image, **colour conversion**) – Used to make the image monochrome(using cv2.COLOR_BGR2GRAY).
ImageGrab.grab(bbox=**Coordinates of the area of the screen to be captured**) – Used to repeatedly(using a loop) capture a specific part of the screen.
The objectives of the code are:
- To use a loop to repeatedly capture a part of the screen.
- To convert the captured image into grayscale.
- Use PyTesseract to read the text in it.

The above code can be used to capture a certain section of the screen and read the text contents of it.
