Iwata: How did you decide on the pixel count?
Kuwahara: It is generally thought that the higher the pixel count the better, but that isnt necessarily so considered from the objective of giving a game console eyes. With higher pixel counts, the physical size of the camera increases, as does the amount of data it must be able to handle, substantially increasing the processing load.
For a digital camera, where youre mainly interested in just capturing an image, simply putting in the requisite circuitry for the number of pixels is enough, but we were expecting to use this for a variety of applications, so we decided on a 0.3-megapixel camera.
Iwata: Makers of digital cameras and cell phones have been competing with each other in recent years, resulting in ever higher pixel counts, so some people may think that 0.3 megapixels isnt much for this day in age, but thats 640 × 480. In other words, you can capture images at a resolution 2.5 times that of the length and width of the DS screen.
With the Nintendo DSi you can enlarge part of a picture youve taken and theres no sense that the resolution isnt high enough. Another problem with higher pixel count is that the memory needed to save each picture increases considerably.
Recently when I use a digital camera with a high pixel count, it takes so much space to store each image that I find myself lowering the resolution when I save. We gave thought to what would be the right size for viewing photos rapidly one after the next on the Nintendo DSi screen. I guess you could say that weve lived up to Nintendos tradition for using technology that withstood the test of time. Besides the camera, what were the other hardware changes? ...(interview continues on)
