Imaging device and electronic device including same

An electronic device comprising:

• an image capturing device comprising a lens assembly, and an image sensor configured to receive light guided by the lens assembly;
• and
• at least one processor configured to acquire a subject image using the image capturing device,
• wherein the lens assembly comprises:
• a plurality of lenses comprising two or more and six or less lenses, the plurality of lenses being aligned along an optical axis and sequentially arranged toward the image sensor, a first lens being farthest from the image sensor among the plurality of lenses, and
• an aperture stop between the first lens and an n-th lens among the plurality of lenses,
• wherein the lens assembly satisfies a first conditional expression, a fourth conditional expression, and a fifth conditional expression,
• wherein the first conditional expression is:
• 0.5≤fn/f≤1.1, the fourth conditional expression is:
• 1.57≤Ndn≤2.1, and the fifth conditional expression is:
• 40≤Vdn≤82, and
• wherein fn is a focal length of the n-th lens, f is a focal length of the lens assembly, Ndn is a refractive index of the n-th lens, and Vdn is an Abbe number of the n-th lens.
