JunoCam

The downlink average data rate of around 325 bits per second will limit the number of images that are captured and transmitted during each orbit to somewhere between 10 and 100 depending on the compression level used.

[3] This is comparable to the previous Galileo mission that orbited Jupiter, which captured thousands of images[4] despite its slow data rate of 1000 bits per second (at maximum compression levels) due to antenna problems that prevented operation with its planned 135,000 bit-per-second communications link.

However, the housing and some aspects of the camera's inner mechanism have been modified to provide stable operation in Jupiter's intense radiation environment and magnetic fields.

Part of its mission will be to provide close up views of Jupiter's polar region and lower-latitude cloud belts, and at Juno's intended orbit the camera is able to take images at up to 15 kilometres (9.3 mi) per pixel resolution.

However, within one hour of closest approach to Jupiter it can take up to 3 kilometres (1.9 mi) pixel, thus exceeding the resolution of Cassini up to that time on Saturn.

[10] The low resolution, rigid mounting, and lossy compression applied before transmission makes it effectively the Juno "dashcam".

In 2005 the Italian Space Agency (ASI) proposed an additional visible light instrument "ItaCam", but instead they built a near-infrared camera/spectrometer, the Jovian Infrared Auroral Mapper (JIRAM) and a Ka-band transponder.
