Assume that you have a camera with a resolution of 5MP where the camera sensor is square shaped with awidth of 14mm. It is also given that the focal length of the camera is 15mm.1. Compute the Field of View of the camera in the horizontal and vertical direction.

The field of view = 66.84°

Explanation:

given:

focal lenght = 15mm

width = 14mm

resolution = 5MP

for us to determine the image size of the square lens of width 14mm

we use Pythagoras theorem,

(diagonal)² = (14)² + (14)²

diagonal = √(392)

the diagonal of the squared camera sensor is the image size in vertical and horizontal.

hence,

image size = √(392) = 19.8mm

Since,

Field of view, fov = 2*arctan(image size/(focal lenght *2))

fov = 2*arctan(19.8/(15 x 2)) = 2*33.425

fov = 66.84°

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
