Which camera sensor format is commonly used in professional DSLRs and mirrorless cameras, offering a large sensor size for high-resolution images?

  1. APS-C

  2. Micro Four Thirds

  3. Full Frame

  4. Medium Format


Correct Option: C
Explanation:

Full Frame sensors are larger in size compared to other formats, allowing for greater light-gathering capabilities and producing images with higher resolution and dynamic range.

What is the primary advantage of a CMOS sensor over a CCD sensor in digital cameras?

  1. Lower power consumption

  2. Faster readout speeds

  3. Higher dynamic range

  4. Improved color accuracy


Correct Option: B
Explanation:

CMOS sensors offer faster readout speeds compared to CCD sensors, enabling continuous shooting at higher frame rates and reducing the risk of motion blur.

Which sensor technology is known for its ability to capture images with minimal noise, even in low-light conditions?

  1. Back-Side Illuminated (BSI)

  2. Front-Side Illuminated (FSI)

  3. Stacked CMOS

  4. Time-of-Flight (ToF)


Correct Option: A
Explanation:

Back-Side Illuminated (BSI) sensors have improved light sensitivity and reduced noise levels compared to Front-Side Illuminated (FSI) sensors, making them ideal for low-light photography.

What is the primary function of a Bayer filter in a digital camera sensor?

  1. Color interpolation

  2. Noise reduction

  3. White balance adjustment

  4. Autofocus


Correct Option: A
Explanation:

A Bayer filter is a color filter array placed over the sensor to capture red, green, and blue light information. This data is then interpolated to create a full-color image.

Which sensor type is commonly used in smartphones and compact cameras due to its small size and low power consumption?

  1. Full Frame

  2. APS-C

  3. Micro Four Thirds

  4. 1/2.3-inch


Correct Option: D
Explanation:

1/2.3-inch sensors are smaller in size and consume less power compared to larger sensor formats, making them suitable for compact cameras and smartphones.

What is the primary advantage of a stacked CMOS sensor design?

  1. Increased resolution

  2. Improved dynamic range

  3. Faster readout speeds

  4. Reduced noise levels


Correct Option: C
Explanation:

Stacked CMOS sensors stack the sensor and processing components vertically, enabling faster readout speeds and reducing rolling shutter distortion.

Which sensor technology is commonly used in high-end mirrorless cameras and offers improved image quality and dynamic range?

  1. CCD

  2. CMOS

  3. Foveon X3

  4. Time-of-Flight (ToF)


Correct Option: C
Explanation:

Foveon X3 sensors capture full-color information at each pixel, resulting in improved image quality and dynamic range compared to traditional Bayer filter sensors.

What is the primary advantage of a Time-of-Flight (ToF) sensor in smartphones and depth-sensing cameras?

  1. Improved low-light performance

  2. Faster autofocus

  3. Accurate depth mapping

  4. Higher resolution images


Correct Option: C
Explanation:

Time-of-Flight (ToF) sensors measure the time taken for light to travel to and from objects, enabling accurate depth mapping and 3D reconstruction.

Which sensor format is commonly used in medium format cameras, offering exceptional image quality and resolution?

  1. APS-C

  2. Micro Four Thirds

  3. Full Frame

  4. Medium Format


Correct Option: D
Explanation:

Medium Format sensors are larger than Full Frame sensors, providing higher resolution and image quality, making them ideal for professional photography.

What is the primary advantage of a global shutter sensor design over a rolling shutter sensor?

  1. Reduced motion blur

  2. Improved dynamic range

  3. Faster readout speeds

  4. Lower power consumption


Correct Option: A
Explanation:

Global shutter sensors capture the entire image at once, eliminating rolling shutter distortion and reducing motion blur, making them suitable for capturing fast-moving subjects.

Which sensor technology is commonly used in some high-end digital cameras and offers improved color accuracy and reduced moiré patterns?

  1. CCD

  2. CMOS

  3. Foveon X3

  4. SuperCCD


Correct Option: D
Explanation:

SuperCCD sensors use a unique pixel arrangement to improve color accuracy and reduce moiré patterns, resulting in sharper and more detailed images.

What is the primary advantage of a dual-pixel autofocus sensor design in digital cameras?

  1. Improved low-light performance

  2. Faster autofocus

  3. Higher resolution images

  4. Reduced noise levels


Correct Option: B
Explanation:

Dual-pixel autofocus sensors have each pixel split into two photodiodes, enabling phase detection autofocus, resulting in faster and more accurate focusing.

Which sensor format is commonly used in entry-level DSLRs and mirrorless cameras, offering a balance between image quality and affordability?

  1. APS-C

  2. Micro Four Thirds

  3. Full Frame

  4. Medium Format


Correct Option: A
Explanation:

APS-C sensors are smaller than Full Frame sensors but larger than Micro Four Thirds sensors, providing a good balance between image quality and affordability.

What is the primary advantage of a backside-illuminated sensor (BSI) over a front-side illuminated sensor (FSI) in digital cameras?

  1. Improved low-light performance

  2. Faster readout speeds

  3. Higher dynamic range

  4. Reduced noise levels


Correct Option: A
Explanation:

Backside-illuminated sensors have improved light-gathering capabilities due to the placement of photodiodes at the back of the sensor, resulting in better low-light performance and reduced noise levels.

Which sensor technology is commonly used in some high-end digital cameras and offers improved image quality and dynamic range, but at the cost of increased noise levels?

  1. CCD

  2. CMOS

  3. Foveon X3

  4. SuperCCD


Correct Option: A
Explanation:

CCD sensors offer excellent image quality and dynamic range, but they are more prone to noise compared to CMOS sensors, especially in low-light conditions.
