Abstract: The pixel number control device has a correlated double sampling (CDS) circuit by which the number of pixel signals outputted from a CCD are controlled. In the record mode, in which a still image corresponding to the pixel signals is recorded in a recording medium, all of the pixel signals are outputted from the CDS circuit. In the monitor-through mode in which a moving image corresponding to the pixel signals obtained by the CCD is indicated by a liquid crystal display, a part of the pixel signals is subsampled and is not outputted from the CDS circuit.

Abstract: An encoded symbol reader for reading and decoding an image of an encoded symbol is capable of operating in three modes and has a CCD, a display, and a light source. In each mode, the reading of an encoded symbol is initiated by a trigger switch. In the first mode, the CCD, display and light source are continuously driven and remain in an ON state. In the second mode, the CCD, display and light source are turned OFF when a decoding operation is completed after the trigger switch is released. In the third mode, the CCD, display, light source are turned OFF after a predetermined period has elapsed after the decoding operation is completed and the trigger switch is released. While operating in the third mode, during the predetermined interval, the re-reading of another symbol can be immediately executed without having to wait for the components to warm up.

Abstract: A device for controlling an imaging device, in which electric charges corresponding to an object are accumulated in photodiodes, and transferred through a vertical transfer CCD and a horizontal transfer CCD to be outputted from the imaging device.

When the electric charges are transferred into the horizontal transfer CCD, the V1 signal and the V2 signal are set to "L". When an exposure is carried out, the V1 signal and the V2 signal are set to "H", and the V3 signal and the V4 signal are changed in the same order as the vertical transfer operation, so that a charge pumping operation is carried out.
