摘要： An image processing apparatus includes a line buffer, an FIR filter serving as an edge enhancement filter that enhances high-frequency components of an image, and an IIR filter serving as a low-pass filter that reduces noise. The same line buffer is used by both the FIR filter and the IIR filter. According to a switching signal, switches enable the FIR filter and disable the IIR filter for a relatively low noise level while the switches enable IIR filter and disable the FIR filter for a relatively high noise level.

摘要： An image projecting apparatus enables the formation of a projected image faithful to original image information by reducing degradation in the projected image due to decrease in imaging performance of a projection optical system. Image information is processed by an image processing device, which includes a first and a second image processor. A light modulating device modulates a flux of light emitted by an illumination optical system based on the processed image information. The modulated flux of light is projected on a screen by a projection optical system. If the image information processed by the first image processor in a pixel region is not within a representable modulation range of the light modulating device, the image information is processed by the second image processor.

摘要： An imaging device includes an imaging element that takes an image of a target object and output an image signal corresponding to the image; a storage unit that stores therein a zero-point adjustment reference value; a brightness detecting unit that detects a brightness of the target object; and a reference-value changing unit that changes the zero-point adjustment reference value when the brightness detected by the brightness detecting unit is equal to or lower than a threshold. A zero point in a level of the image signal output from the imaging element is adjusted by using the zero-point adjustment reference value stored in the storage unit.
