Abstract:

A system for the storage and retrieval of audio files includes an audio storage and retrieval device and a label with an encoded memory storage address. The audio storage and retrieval device includes a memory for storing a plurality of audio files where each stored audio file corresponds to a unique memory storage address, a decoder for reading an encoded memory storage address from the label, and a control module: i) in communication with the decoder for deriving the memory storage address corresponding to the encoded memory storage address and ii) in communication with the memory for retrieving an audio file corresponding to the memory storage address.

Assignee:

Polaroid Corporation - Cambridge MA

International Classification:

G03B 700

US Classification:

354415

Abstract:

An automatic exposure system for an electronic flash camera incorporates an arrangement for measuring the reflectivity of a scene illuminated by the electronic flash prior to exposure in order to determine certain photographic scene characteristics for use in controlling a subsequent photographic exposure, an arrangement that substantially reduces the complexity and energy consumption of the electronic flash system while improving the ability of the exposure control system to accurately determine these characteristics. The arrangement includes the pre-exposure firing of the electronic flash to illuminate a scene with a pulse of light for a short, fixed period of time. A reflection of this light pulse is integrated for a portion of this fixed period of time. The final integrated value of the reflected light is a measure of subject reflectivity. This integrated value is then employed to derive the desired photographic scene characteristics.

International Classification:

G03B 708

US Classification:

Abstract:

An exposure control system in a self-developing camera having a user trim adjustment for manually varying the exposure time of a picture over a limited range of exposure times is provided with a photocell for measuring the level of ambient light in a scene to be photographed and a memory for temporarily storing this scene light information. If after taking a picture of a particular scene the camera operator determines that the resulting photograph was either too light or too dark and chooses to take another picture of the particular scene, the trim control is manually adjusted to obtain the desired picture brightness level. In the present arrangement, when the particular scene is re-framed and the trim control is adjusted, the ambient scene light information stored in memory is varied, and not the ambient scene light subsequently sensed by the photocell in order to compensate for the fact that upon re-framing the scene the photocell sees a different portion of the same scene and therefore a different ambient scene light level and that the intent of the operator in such instances is to alter the exposure time relating to the initial scene that produced the unwanted scene light conditions and not that relating to the re-framed scene.
