Sensor size comparison
Sensor size is generally a good indicator of the quality of the camera. Sensors can vary greatly in size. As a general rule, the bigger the sensor, the better the image quality.

Bigger sensors are more effective, because they have more surface area to capture light. An important factor when comparing digital cameras is also camera generation. Generally, newer sensors will outperform the older.

Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next. It tells you how close the pixels are to each other.

The bigger the pixel pitch, the further apart they are and the bigger each pixel is. Bigger pixels tend to have better signal to noise ratio and greater dynamic range.

Diagonal

Diagonal is calculated by the use of Pythagorean theorem:
Diagonal =  w² + h²
where w = sensor width and h = sensor height

Kodak EasyShare C195 diagonal

The diagonal of Kodak EasyShare C195 image sensor is not 1/2.3 inch as you might expect, but approximately two thirds of that value. If you want to know why, see sensor sizes.

w = 6.16 mm
h = 4.62 mm
Diagonal =  6.16² + 4.62²   = 7.70 mm

Kodak EasyShare C1550 diagonal

The diagonal of Kodak EasyShare C1550 image sensor is not 1/2.3 inch as you might expect, but approximately two thirds of that value. If you want to know why, see sensor sizes.

w = 6.16 mm
h = 4.62 mm
Diagonal =  6.16² + 4.62²   = 7.70 mm


Surface area

Surface area is calculated by multiplying the width and the height of a sensor.

Kodak EasyShare C195 surface area

Width = 6.16 mm
Height = 4.62 mm

Surface area = 6.16 × 4.62 = 28.46 mm²

Kodak EasyShare C1550 surface area

Width = 6.16 mm
Height = 4.62 mm

Surface area = 6.16 × 4.62 = 28.46 mm²


Pixel pitch

Pixel pitch is the distance from the center of one pixel to the center of the next measured in micrometers (µm). It can be calculated with the following formula:
Pixel pitch =   sensor width in mm  × 1000
sensor resolution width in pixels

Kodak EasyShare C195 pixel pitch

Sensor width = 6.16 mm
Sensor resolution width = 4392 pixels
Pixel pitch =   6.16  × 1000  = 1.4 µm
4392

Kodak EasyShare C1550 pixel pitch

Sensor width = 6.16 mm
Sensor resolution width = 4699 pixels
Pixel pitch =   6.16  × 1000  = 1.31 µm
4699


Pixel area

The area of one pixel can be calculated by simply squaring the pixel pitch:
Pixel area = pixel pitch²

You could also divide sensor surface area with effective megapixels:
Pixel area =   sensor surface area in mm²
effective megapixels

Kodak EasyShare C195 pixel area

Pixel pitch = 1.4 µm

Pixel area = 1.4² = 1.96 µm²

Kodak EasyShare C1550 pixel area

Pixel pitch = 1.31 µm

Pixel area = 1.31² = 1.72 µm²


Pixel density

Pixel density can be calculated with the following formula:
Pixel density =  ( sensor resolution width in pixels )² / 1000000
sensor width in cm

You could also use this formula:
Pixel density =   effective megapixels × 1000000  / 10000
sensor surface area in mm²

Kodak EasyShare C195 pixel density

Sensor resolution width = 4392 pixels
Sensor width = 0.616 cm

Pixel density = (4392 / 0.616)² / 1000000 = 50.84 MP/cm²

Kodak EasyShare C1550 pixel density

Sensor resolution width = 4699 pixels
Sensor width = 0.616 cm

Pixel density = (4699 / 0.616)² / 1000000 = 58.19 MP/cm²


Sensor resolution

Sensor resolution is calculated from sensor size and effective megapixels. It's slightly higher than maximum (not interpolated) image resolution which is usually stated on camera specifications. Sensor resolution is used in pixel pitch, pixel area, and pixel density formula. For sake of simplicity, we're going to calculate it in 3 stages.

1. First we need to find the ratio between horizontal and vertical length by dividing the former with the latter (aspect ratio). It's usually 1.33 (4:3) or 1.5 (3:2), but not always. 22.8 × 15.5 sensor for example has a ratio of 1.47.

2. With the ratio (r) known we can calculate the X from the formula below, where X is a vertical number of pixels:
(X × r) × X = effective megapixels × 1000000    →   
X =  effective megapixels × 1000000
r
3. To get sensor resolution we then multiply X with the corresponding ratio:

Resolution horizontal: X × r
Resolution vertical: X

Kodak EasyShare C195 sensor resolution

Sensor width = 6.16 mm
Sensor height = 4.62 mm
Effective megapixels = 14.50
r = 6.16/4.62 = 1.33
X =  14.50 × 1000000  = 3302
1.33
Resolution horizontal: X × r = 3302 × 1.33 = 4392
Resolution vertical: X = 3302

Sensor resolution = 4392 x 3302

Kodak EasyShare C1550 sensor resolution

Sensor width = 6.16 mm
Sensor height = 4.62 mm
Effective megapixels = 16.60
r = 6.16/4.62 = 1.33
X =  16.60 × 1000000  = 3533
1.33
Resolution horizontal: X × r = 3533 × 1.33 = 4699
Resolution vertical: X = 3533

Sensor resolution = 4699 x 3533


Crop factor

Crop factor or focal length multiplier is calculated by dividing the diagonal of 35 mm film (43.27 mm) with the diagonal of the sensor.
Crop factor =   43.27 mm
sensor diagonal in mm


Kodak EasyShare C195 crop factor

Sensor diagonal in mm = 7.70 mm
Crop factor =   43.27  = 5.62
7.70

Kodak EasyShare C1550 crop factor

Sensor diagonal in mm = 7.70 mm
Crop factor =   43.27  = 5.62
7.70

35 mm equivalent aperture

Equivalent aperture (in 135 film terms) is calculated by multiplying lens aperture with crop factor (a.k.a. focal length multiplier).

Kodak EasyShare C195 equivalent aperture

Aperture is a lens characteristic, so it's calculated only for fixed lens cameras. If you want to know the equivalent aperture for Kodak EasyShare C195, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Kodak EasyShare C195 is 5.62

Kodak EasyShare C1550 equivalent aperture

Aperture is a lens characteristic, so it's calculated only for fixed lens cameras. If you want to know the equivalent aperture for Kodak EasyShare C1550, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Kodak EasyShare C1550 is 5.62
