Technology and Quality that Support our Business

Technology that creates new value

Development at Casio is driven by the constant advancement of original technologies that drive the expansion of the locations and applications where its products and services can be used, thereby creating new value.


Technologies such as shock and water resistance make products more resilient, expanding the locations where they can be used and enabling new applications. They also have the advantage of extending products’ useful life by reducing damage that can be caused by careless handling.

The G-SHOCK shock-resistant watch overturned the traditional concept of watches as fragile precision instruments, and made it easy to use watches in intense sports and outdoor situations.

In pursuit of long-lasting value, the EX-word electronic dictionary has a durable design that assumes that the product will be put under pressure in students’ bags. Also, handheld terminals for business use are built to withstand the inevitable drops.


Technologies for miniaturization and high-density mounting allow products to be made smaller and/or thinner, delivering both improved usability and attractive design. They also free up space inside the product, making room for enhanced functionality.

The stylish Privia digital piano was given a slim profile by miniaturizing its structure while still pursuing the keyboard touch of a grand piano created by the hammer’s own weight. Since it is easy to set up and move, the Privia provides greater freedom in where it can be played, making it easier to enjoy playing the piano.

Power saving

Technologies that reduce product power consumption, enable smart use of a small amount of power, or increase power generation efficiency all improve battery life. This makes products usable for extended periods of time. The surplus power can also be used to add new functions or reduce battery size to enhance design quality.

Casio solar-powered analog watches use a shadow-dispersing solar panel that generates electricity efficiently. By optimizing the cell shape of the solar panel, the decrease in power generation due to the shadow of the hands is minimized while watch functionality and design of the dial are enhanced.

Sound source and acoustics

In its sound source and acoustic technologies, Casio pursues the tone of acoustic instruments and new performance possibilities using digital technology.

In its sound sources for digital pianos, Casio sought a more natural, realistic grand piano tone by using multi-dimensional morphing technology to smoothly change the reverberation and resonance according to the strength of keystrokes and the length of time keys are held down to offer a more expressive performance experience. Vocal Synthesis, a sound source technology that produces singing voices on a musical instrument, allows users to express smooth human singing just by playing the keyboard. It does this by combining voice tone data with the phrases of lyrics generated by simulating how the instrument should sing based on a massive amount of singing voice data.

Light source and optical design

Light source and optical design technologies are used in projectors, which are finding wider application as products are made smaller but projection brighter, and also in digital cameras for medical uses that require detailed observation and recording.

The original Casio laser and LED hybrid light source for projectors achieves high brightness without using a high-pressure mercury lamp, and it has a life of about 20,000 hours. The long life reduces the labor and cost of lamp replacement. Additionally, this light source means that Casio projectors can be used immediately after turning them on, since they can project within a few seconds without waiting. What is more, they do not need to cool down after being turned off.

The original Casio dermatology camera for dermatologists can clearly record images with reduced distortion using a specialized lens that does not need to be changed between taking shots of the whole affected area and close-up shots of lesions.

Image processing

Casio anticipates its outstanding image processing technology to find applications in various fields such as medical care and the security market.

Images of affected areas shot with the dermatology camera  for dermatologists can make it easy to observe lesions thanks to an image conversion feature that can clarify the internal structure of a lesion and emphasize blood vessels, simply by using a PC application. The Casio COLPOCAMERA for obstetricians and gynecologists uses image processing to make it easier to evaluate the color and shape of the cervix, on which light does not shine during image capture.

Going forward, Casio will aim to enhance medical care through AI analysis by combining these image processing technologies with the knowledge of medical specialists.

Sensing and algorithms

Sensing and algorithm technologies are used in sports, healthcare, and other fields. They combine sensing technology that measures environmental data such as bearing, barometric pressure/altitude, and temperature, biological data such as heart rate and step count, and exercise data with algorithm technology that visualizes the information and provides it in the form of a useful function to the user.

The Casio motion sensor, equipped with GPS and a nine-axis sensor, analyzes with great accuracy the body’s movement while running, and visualizes the user’s running form by connecting with the Runmetrix smartphone app for running. This makes it possible for users to check their running form and helps them understand where to make improvements.

Quality initiatives

Casio's primary objective is to make products that work reliably in any environment, and can always be used with safety. From the initial engineering phase to the release of the final product, Casio takes great pains to ensure there are no compromises on manufacturing quality.

Thorough quality testing in the design stage

Casio has quality standards designed to ensure that products can be used in all kinds of situations, and the company performs repeated stringent testing through product prototyping. For example, Casio electronic dictionaries are subjected to a pressure test, where a load is placed on the dictionary unit, and robustness is verified from the top-down direction. Only those prototypes that meet all the quality criteria for the product concerned can move on to the factory production process. These criteria include resistance to vibration, dropping, dust, salt water, UV light, and static electricity, as well as extremes of temperature and humidity.

Production system enhances quality with a high level of manufacturing technology

The Premium Production Line at Yamagata Casio produces high-end Casio brand watches. With a combination of technology to maximize accuracy using the company’s own special manufacturing equipment and a high level of human skill found only in top certified personnel, Yamagata Casio is pursuing high-quality and high-precision manufacturing. This Japanese manufacturing expertise is also transferred to Casio production sites in other countries, as part of a global production system producing a high level of quality worldwide.
