Algorithm to differentiate camera shake from photographic movement Angular velocity sensor (to detect camera shake) Real time waveform analysis Signal isolation Camera shake Intended camera movement Outstanding image stabilisation performance Achieves smooth movement of the camera Software to differentiate camera shake from intended camera movement plays a vital role in image stabilisation. We developed our own algorithm to differentiate small camera shake which happens when holding the camera, from the swift movement of the camera that is intended. These intended movements should not be mistaken for camera shake. We developed an algorithm that analysed the waveforms for the shaking of the camera in real time, and isolated camera shake from intended movement, and in doing so, we were able to reduce the delay in tracking intentional camera movements. Kanzawa It is crucial to control the sound made by the motor drive, which is used to move the large lens unit. The initial trial piece made tremendous noise. The vibrations of the motor were picked up by the external components and in turn converted to noise, which could be heard even from a metre away. In most cases, enough room is created around the microphone to solve this kind of noise problems. However, there is no gap around the lens unit, and the parts are so closely placed that it is difficult to position the microphone even slightly apart. Every department was involved to solve this problem. Various innovative solutions were implemented to keep the noise down to a level where it does not affect the videography. Sakai The first prototype we developed was extremely large, and until the very end, we were anxious about whether it was acceptable. But once the product was finished, we were amazed at how effective the image stabilisation was, and we have also received favourable reviews from our customers.
How would you like people to use Handycam®, and what are the points that you would like the user to focus on Tsuchihashi When you are shooting a video, you don’t always keep your eyes on the camcorder’s screen. It’s likely you will look up to watch your son shoot a goal in a football match, for instance. A lot of the time, this is the instant when the camera shakes, and as a result, you might miss capturing the moment you wanted to record. We developed this feature to ensure that you get a clear, steady video footage even in such cases. I want you to use this camcorder at sporting events, like your child’s sports day. Hattori From an engineer’s perspective, I would like to highlight the strength and durability. Even without turning the camera on, the lens unit still moves when being carried, so there will be degradation of the components within. Therefore, we calculated the number of times the unit will be carried and used from the time the customer purchases the camera until it can no longer be used, then used these calculations to design its strength and durability. The lens unit alone has cleared the durability test a million times, hence we have absolute confidence in its durability. Kanzawa As a developer, there are so many features that I would like you to take note of. For instance, the cover around the lens is the result of trials with about 100 different samples which we made before deciding on this colour. However, what I want most of all is for our customers to visit our Sony stores and actually hold the camera and use it. I would like them to witness the effectiveness of the image stabilisation out for themselves. Sakai Not just the picture quality, but also the sound quality is good. What’s more, the Handycam® HDR-PJ760V also allows you to view your videos through a projector. Since this is a highly feature-rich and efficient product, I can recommend it with confidence. I want our customers to go to the stores to personally experience its effectiveness.
