Sanyo VPC-J1EX instruction manual About the resolution and compression settings see

HINT

œAt a B resolution, the camera processes the captured image internally to produce a 2880 x 2160-pixel image.

œWhen capturing images at a B resolution, it takes 4 seconds after the shutter release button is pressed before the data is recorded (when using the supplied SD Memory Card).

NOTE

œThe digital zoom cannot be used when the resolution is set to B.

About the resolution and compression settings (see page 101)

œThe image captured by a digital camera consists of a collection of small dots. The resolution refers to the number of these dots, and the greater the number, the higher the image quality. As the resolution increases, the size of the resulting data also increases, and the number of images that can be captured decreases. To compensate for this, this digital camera is able to compress the data. This digital camera uses JPEG compression. If JPEG compression is used, when the image is played back, an extremely small portion of it is lost. The higher the compression rate, the more of the original image is lost.

Therefore, in the still image and sequential shots shooting modes, this digital camera also allows you to store image data at extremely low

compression to ensure that a minimum of the original image is lost. This is the a mode. Since the image data is large when the a mode is used, compared to c or b compression, the digital camera requires more time both to store the data after the shutter release button is pressed and to display the image in the playback mode.
