PROBLEM TO BE SOLVED: To provide an adjusting method for digital imaging which improves the resolution of an image. SOLUTION: An image is automatically enhanced by correcting the reference voltage (VREF), gain, and integration period of a differential amplifier 24 so that an input using the whole dynamic range of a differential analog-digital converter(ADC) 32 is supplied to the ADC. When it is used together with a CMOS array, imaging logic 8 is manufactured on a single chip 20 together with the array by using fast and inexpensive combination logic for correction. The digital resolution of an image of a part of interest in spectrum is increased by enlarging a desired part (176-178) of the luminance spectrum of the image.
