An image pickup apparatus including a photoelectric conversion element, first, a shutter speed for still-image pickup is set. Next, an image-pickup frame rate is set on the basis of the shutter speed for still-image pickup. Then, an operation of the photoelectric conversion element is controlled such that picked-up images are output at the set image-pickup frame rate. When the image-pickup frame rate that is set is higher than a moving-image-reproducing frame rate, a frame for use in a moving-image reproduction is generated from a plurality of frames of the picked-up images and reproduction is performed at the moving-image-reproduction frame rate.

A light-emitting device can be configured to have little variation in light emission characteristics even at increased temperatures. A light-emitting device can include a light-emitting section for emitting light with a predetermined wavelength, and a fluorescent material for absorbing a part of light emitted from the light-emitting section and emitting light with a longer wavelength. The light-emitting device can mix the light with the predetermined wavelength from the light-emitting section and the light with the longer wavelength from the fluorescent material, and thereby emit a mixed light. The fluorescent material can include single crystal grains in which primary grains have a diameter of 1 &#x3bc;m or less. Crystal defects, such as a grain boundary, do not often and sometimes never occur in the single crystal grain having a diameter of 1 &#x3bc;m or less. Thus, it is possible to restrain a phenomenon in which a crystal defect non-radially emits absorbed energy (as heat) which then reduces light emission efficiency.

Charges are transferred from vertical charge transfer devices of a solid-state image sensing device to horizontal charge transfer device via buffer storage cells. Charges obtained from a unessential area out of the transferred charges are discarded by operating the horizontal charge transfer device, and charges obtained from a specific area out of the transferred charges are normally read out by operating the horizontal charge transfer device.
