Tokyo, January 26, 2021 — Casio Computer Co., Ltd. announced today the upcoming release of the DZ-D100 DERMOCAMERA that allows close-up shots with the lens directly touching the skin as well as ordinary shots, all using a single camera. The new product was created based on collaborative research Casio conducted with Chiba University. At the same time, Casio will also release D’z IMAGE Viewer, a PC software application developed with Shinshu University that facilitates management of the captured images, and the lightweight DZ-S50 dermoscope, which is fitted with a wide-aperture 40.5mm diameter lens that facilitates observation of larger areas of skin and was developed with Chiba University.

In the past, when photographing lesions, it was typical to take close-up shots of the affected area using a commercial camera fitted with a special external lens, which made the camera large and heavy. In addition, taking ordinary shots took time and effort, including the need to change lenses or to use two separate cameras.

Leveraging Casio’s powerful camera technology and the knowledge of expert dermatologists, the DZ-D100 delivers exactly what dermatologists want — close-up shots to confirm the color and structure of a lesion as well as shots of the affected area, including the area around the lesion to confirm its position — all using a single compact, lightweight camera.

The DZ-D100 takes the polarized shots needed to confirm color and structure inside the skin, non-polarized shots to record the lesion on the surface of the skin, and UV* shots that clearly show the margins, including hidden spots and blurred moles with a single click of the shutter button. Because each image can be captured from the same angle, it is useful for comparison and verification.

  • UV shots use safe light with a wavelength of 405nm.

The captured images can also be automatically transferred to a PC by connecting the DZ-D100 to the D’z IMAGE Viewer image management software via Wi-Fi. Images taken with an entered ID are automatically sorted according to each ID, eliminating the need for cumbersome folder sorting. In addition, a scale can be displayed on close-up shots, allowing the size of the lesion to be confirmed on the screen, and it is also possible to measure the distance between two points such as edge to edge on the lesion using the measuring function.

The DZ-S50 dermoscope features a function that enables quick and simple one-touch switching between polarized and non-polarized light. It is also lightweight, weighing in at only about 125g, which makes it conveniently portable. Lens zoom can also be increased from the default 6x to 9x using the DSL-50M optional conversion lens, which easily attaches and detaches with built-in magnets. This allows the user to switch easily from observing larger areas of skin to small lesions.

Going forward, Casio will continue to help reduce the burden on physicians by making medical examinations more routine, looking to reach new markets with its products and services, especially areas where the threat of skin disease in particularly high, including Australia.

Casio History in the Dermatology Field

Based on the image conversion technology Casio created in the development of digital cameras, in 2015 Casio released its free dermoscopy learning service D’z IMAGE . The learning service allows medical professionals to efficiently learn about dermoscopic examinations* using image conversion functions that elucidate the structure of lesions and their blood vessel distribution. Dr. Toshitsugu Sato of Sato Dermatology Clinic says, “With just one click, you instantly get a variety of different types of enhanced dermoscopy structure images, which makes efficient study of dermoscopy possible.” Casio has subsequently enhanced the content of the service, which represents a collaboration between medicine and engineering.

Casio has been providing DERMOCAMERA and image management software in Japan since 2019, receiving feedback from research collaborators including: “The DERMOCAMERA is versatile and lightweight, just like a ninja,” (Dr. Yaei Togawa of Chiba University) and, on the image management software, “The advantage is that patient images can be managed securely without the need to upload them to the cloud” (Dr. Hiroshi Koga of Shinshu University). In addition, Professor Masaru Tanaka of Tokyo Women’s Medical University Medical Center East, who is an authority on dermoscopy, has commented that the DERMOCAMERA is the ideal integrated digital camera, in that it is developed specifically for dermoscopy and is light and easy to hold.

Casio is also developing a skin cancer diagnosis support system that uses artificial intelligence and will continue contributing to medical treatment in the dermatology field.

Main Features of DZ-D100

Close-up and ordinary shots can be captured with a single camera

Dermatologists typically used a commercial camera fitted with a special external lens to take close-up shots of lesions. Thus, they had to change lenses or use two separate cameras when also taking ordinary shots. The DZ-D100 has made it possible to take close-up and ordinary shots with a simple switch of modes, so all the images needed for an examination can be taken easily.

Takes polarized/non-polarized/UV shots with a single click of the shutter button

The camera controls the reflection of light, making it possible to take the polarized shot needed to capture color and structure inside the skin immediately below the skin’s pellicle, the non-polarized shot that is handy for capturing the lesion on the surface of the skin, and the UV shot that clearly shows lesion margins including hidden spots and blurred moles that do not stand out with polarized light — all with just one click of the shutter button. This not only eliminates time and effort, but also enables each of the three images to be captured from the exact same angle, which is very useful when making comparisons.

Compact and lightweight: Designed to be held in one hand

While the total weight of many cameras with a conventional external lens is over 1kg, the new Casio DERMOCAMERA only weighs about 400g. The user can capture images without camera shake due to the weight. In addition, Casio adopted a shape designed for holding the camera in one hand as well as two, taking ease of grip into consideration.

High-definition image quality showing everything from the lesion to the affected area as a whole

The integrated design from the image sensor through the lens reduces distortion and allows accurate capture of lesion shape. In addition, the LED light emitted from inside the lens when capturing close-up shots has minimal lighting inconsistency, ensuring uniform image quality over the entire photographed area from the center to the edges of the screen. Meanwhile, when capturing ordinary shots, by using the LED ring light, the camera can be held while lit, unlike a strobe flash, allowing the image to be recorded as seen on an LCD screen.

Main Features of D’z IMAGE Viewer

Automatic transfer from DZ-D100 to D’z IMAGE Viewer

Connecting the DZ-D100 to the D’z IMAGE Viewer via Wi-Fi automatically transfers captured images to a PC. In addition, images taken with an entered ID are automatically sorted according to each ID, eliminating the need for cumbersome folder sorting.

Scale display function shows lesion size

Lesion size can be easily confirmed with a function that displays a scale on images captured in close-up. The distance between two points can also be measured using the measuring function, making it possible to measure the size of the necessary section.

Main Features of DZ-S50

Lightweight dermoscope facilitates wide-ranging observations

Features a wide-aperture 40.5mm diameter lens to meet the need for observing larger areas of skin while also allowing easy observation of affected areas. Distortion is reduced to the edge of the lens to allow smooth observations. Weighing in at only about 125g, it is lightweight and conveniently portable.

Zoom can be easily changed with the optional conversion lens

Lens zoom can also be increased from the default 6x to 9x using the DSL-50M optional conversion lens, which easily attaches and detaches with built-in magnets. This allows the user to switch easily from observing larger areas of skin to small lesions.
